Description

HEAT EXCHANGING SYSTEM
Technical Field
The present invention relates to a heat exchanging system capable of exchanging heat generated from the human body by circulating the forcedly blown air into the inside, and more particularly, to a heat exchanging system, which a user can wear the heat exchanging system or lie on the heat exchanging system comfortably even in summer.
Background Art
In general, a mattress put on a bed or the floor of a room to take a rest or a sleep and a mattress used in a chair or a seat for a car generally have a cover made of cloth and cotton or sponge contained in the cover, thereby providing a thermal insulation effect and a cushiony effect.
However, such mattresses are improper in summer when people sweat profusely. So, thin cloth or a mat made of pieces of bamboo instead of the mattresses, but they cannot provide the thermal insulation effect and cushiony effect so much as the mattresses.
Therefore, the conventional mattresses may give unpleasantness to a user because of sweat generated from the user's body when the temperature rises and injure the user's health. Especially, if a handicapped person or a patient, who has to lie on a bed for a long time, uses the mattress, the handicapped person or patient may suffer from prickly heat or tumor on the user's back. If an electric fan or an air conditioner is used to relieve the prickly heat or tumor, other diseases such as air-conditioningitis may be caused.
Furthermore, in case of shoes for protecting feet and providing the feet with adiabatic effect and a helmet used when the user operates two-wheeled vehicle or takes part in various leisure activities, because sealing a part of the user's body, they give unpleasantness to the user due to sweat.
Therefore, it is required to develop a new heat exchanging system, which can be embedded in the conventional mattress, shoes or helmet to allow the user to take a rest or sleep or work comfortably or work in an agreeable condition.
Disclosure of Invention
Accordingly, the present invention is a heat exchanging system, which can exchange a user's body heat with forcedly or naturally blown air by circulating the air into the inside uniformly, thereby preventing unpleasantness or diseases due to sweat generated from the user's body part contacting with a mattress in summer and preventing prickly heat or tumor had to a patient who lies on a bed for a long time.
To achieve the above object, the present invention provides a heat exchanging system including an air blowing part for blowing air generated by an air blower or air naturally blown into the inside; and a heat exchanging part for thermally exchanging the user's body heat contacting with the air.

If the integrated supporting member 210 and the bulkhead members 220, 230 and 240 are wrapped with cloth, which has good air-permeability and good touch feeling, while the inlet and outlet of each stage are opened, so that a heat exchanging part 200 according to the first embodiment is finished. If the finished heat exchanging part 200 is embedded into an upper end of a mattress, which is equal to or larger than the heat exchanging part 20, and the mattress and the heat exchanging part are wrapped with cloth, which has good air- permeability and good touch feeling, while the inlet and outlet of each stage are opened, the mattress having a heat exchanging function can be manufactured. A use process of the mattress in which the heat exchanging system according to the present invention is embedded will be described as follows.
First, the heat exchanging mattress is put on the floor of a room or on a bed, the air blower 101 is installed at a position where the air circulates well, the insertion member 103 of the air blow pipe 102 is connected to the inlet 214 of the supporting member 210 of a lower end of the mattress, and the suction pipe 104 is connected to the outlet 235 of the second bulkhead member 230 of an upper end of the mattress. If a user lies on the mattress for taking a sleep or a rest and operates the air blower 101, wind generated from the air blower 101 is sterilized, deodorized and dried during passing the filtering device 106, flowed into a space between the supporting member 210 and the first bulkhead member 220 through the air blow pipe 102, passes the first vent hole 201 formed in the cross plate 221 of the first bulkhead member 220 and the second vent hole 202 formed in the second bulkhead member 230, and then respectively flowed into an inner space formed by the first and second bulkhead members 220 and 230 and into an inner space formed by the second and third bulkhead members 230 and 240 in order. At this time, the air flowed into each space becomes slow in velocity while passing the first and second vent hole 201 and 202, of which an upper portion and a lower portion are in the opposite direction to each other, in order.
The air flowed into the space between the second and third bulkhead members 230 and 240 absorbs heat generated from the user's body stopping the third vent hole 203 and exchanges heat, and then is circulated through the outlet 235 of the second bulkhead member 230 and through the suction pipe 104 to the air blower 101. If the above process is repeated, the heat generated from the user's body is exchanged with heat of the room temperature, and thereby the user is prevented from sweat. In the first embodiment of the present invention, an air cooling device, i.e., air conditioner may be used instead of the air blower, and the suction pipe may be removed to discharge the heat-exchanged air naturally.
In a second preferred embodiment, two heat exchanging parts connected to each other may be applied to a chair or a seat for a car. Referring to FIGS. 4 and 5, detailed structure and application method will be described as follows. FIG. 4 illustrates an exploded perspective view of a heat exchanging system according to a second embodiment of the present invention, and FIG. 5 illustrates a structural view showing an installation state of the heat exchanging system according to the second embodiment of the present invention.
The heat exchanging system according to the second embodiment of the present invention is manufactured by connecting the two heat exchanging parts of the first embodiment.
Concretely, the heat exchanging system according to the second embodiment is manufactured in such a manner that first and second heat exchanging parts, which are the same as the heat exchanging part of the first embodiment, are connected to each other by a flexible T-shaped air blow pipe 11 and a suction pipe 12.
Here, the T-shaped air blow pipe 11 and the suction pipe 12 has a front end of T-shape and two insertion members 13, and the two heat exchanging parts are located in such a manner that the inlets of the supporting members are faced to each other. As shown in FIG. 5, the flexible T-shaped air blow pipe 11 and suction pipe 12 can take a desired shape, for example Y-shape, when they are installed.
If the finished heat exchanging parts are embedded into a chair or a mattress of a seat for a car, i.e., mattress for a seat or a back seat and the heat exchanging parts and the mattress are wrapped with cloth, which has good air- permeability and good touch feeling, while the inlet and outlet of each stage are opened, the mattress or chair having a heat exchanging function can be manufactured.
A use process of the chair or the seat for the car manufactured by the above will be described as follows. First, the air blower 14 is installed at a position where the air is circulated well, the insertion members 13 of the air blow pipe 11 are connected to the inlet of the supporting member of a lower end of each heat exchanging part, and the suction pipe is connected to the outlet of the second bulkhead member of an upper end of each mattress.
In the above installation state, if the user lies or sits down on the chair or mattress to take a rest or drive the car and operates the air blower 101, the air flowed into each heat exchanging part embedded into each mattress absorbs heat generated from the user's body and exchanges heat while passing inner spaces formed by the supporting member and the bulkhead members, and is circulated through each outlet and through the suction pipe 12 to the air blower 14 again. If the above process is repeated, the heat generated from the user's body is exchanged with heat of the room temperature, and thereby the user is prevented from sweat.
In the second embodiment of the present invention, in case that the heat exchanging system is used in the seat for the car, an air cooling device, i.e., air conditioner, may be used instead of the air blower, and the suction pipe may be removed to discharge the heat-exchanged air naturally.
