Description
Technical field
The present invention relates to a kind of device of technical field of heat exchangers, specifically is a kind of U type gravity assisted heat pipe that is used for refrigeration system.
Background technology
Heat pipe heat exchanging is a kind of high-efficiency heat conduction element that utilizes phase transformation to carry out the heat transmission, has obtained extensive use in Aero-Space and various industrial recuperation of heat occasion.Heat pipe mainly is divided into the Horizontal heat pipe of gravity assisted heat pipe and capillary auxiliary reflux etc. on the liquid reflux type at present.Gravity assisted heat pipe inside does not generally have capillary structure, and the liquid of condensation relies on gravity to get back to the evaporator section of heat pipe bottom from heat pipe top.
In the freeze drying system, dehumidification process mainly as refrigeration system evaporator or central air-conditioning surface cooler on carry out, processed air on surface cooler before this temperature be reduced to dew-point temperature, cooling is dried again, through behind the surface cooler, temperature reduces, and passes through the evaporimeter of refrigeration system or special heater more usually, enters air conditioner surroundings then.By rational heat exchange form, air before the surface cooler and the air through dehumidifying carried out heat exchange, then can reduce surface cooler to handling the pre-refrigeration duty of air, also reduced behind the surface cooler heating load to the heater of handling air.Heat pipe by arrange heat pipe in the surface cooler front and back end, just can be realized above-mentioned functions as a kind of high thermal conductivity structure, reduces the sensible heat cooling load of processed air, is applied in a lot of at home and abroad engineerings of this technology.But in a lot of occasions, the evaporimeter or the surface cooler of the refrigeration system that is used to lower the temperature are vertically placed, the air channel level, and heat exchanger is arranged closely in the air channel, in the placement process because the compactedness requirement of actual air-conditioning box, usually heat pipe design becomes horizontal U type to place, and wherein curved a little higher than another arm of an arm of U moves in the gravity assisted heat pipe mode.The evaporation ends and the condensation end that are heat pipe are arranged in the position of surface cooler front and back near surface cooler, and the level height of evaporation ends is only a little low a little than condensation end, and this is most of dehumidification process pipe of energy-saving heat form.This heat pipe form in running because the existence of U type elbow, condensate liquid and steam the influencing each other in this zone of evaporation back high velocity stream that low speed is refluxed toward condensation end, partial reflux liquid is because the rolling action of gas is difficult to get back to evaporation ends, thereby influences the Heat Transfer of Heat Pipe on Heat Pipe ability.This influence is higher than influencing each other in flat segments far away in the curved zone of U type.Particularly, be easy to because the gas, liquid in U type zone influences mutually and early entrainment limit occurs, thereby influence the performance of heat exchanger, cause the performance driving economy of system to be affected for the situation of longer heat exchanger tube.
Document " utilizing heat exchange of heat pipe to improve small-sized dehumidifier wet-out property experiment " has been discussed the heat pipe operation characteristic of the U type heat pipe structure that adopts in the dehumidifier in (the 12 national heat pipe proceeding, in October, 2010).Find that by numerical simulation heat pipe is in service, the gas-liquid vortex flow obviously influences the fluid transport process of evaporation and condensation segment in the adiabatic bend pipe, thereby cause the fluctuation of boundary, and, under the steady flow of heat density conditions, cause the instability of boundary for above-mentioned reasons, vapor-liquid temperature fluctuates thereupon.Therefore, the boundary heat and mass instability of evaporation and condensation segment.
Summary of the invention
The present invention is directed to the prior art above shortcomings, a kind of U type gravity assisted heat pipe that is used for refrigeration system is provided, this device can guarantee the heat pipe of heat exchange of heat pipe under the long situation of length, working stability, and keep heat-transfer capability preferably.The application of this invention can improve the effect on moisture extraction of air-conditioning system, and plays energy-conservation effect.
The present invention is achieved by the following technical solutions, the present invention includes: evaporator section, condensation segment, U type bend pipe and inner sleeve spare, wherein: an end of evaporator section and condensation segment is connected the pipeline of heat exchanger respectively, the other end of evaporator section and condensation segment is connected with the two ends of U type bend pipe respectively, and inner sleeve spare is welded on inside heat pipe.
Described inner sleeve spare adopts imperforate plate or porous plate, shape of this inner sleeve spare and heat pipe U type elbow profile are complementary, wall thickness 0.2～1.0mm, inner sleeve spare forms annulus with the internal face of U type bend pipe, and inner sleeve outer wall and outer tube wall clearance distance are the 1/20-1/5 of outer tube diameter.
The outer wall of the U type heat pipe of described evaporator section, condensation segment is provided with heat exchange fin.
Inner sleeve spare of the present invention has the gas that inside is mobile in opposite directions and the function of fluid separation applications, during normal the operation, in U type bend pipe, the condensed fluid mainly space between inner sleeve spare and U type pipe is back to evaporator section, steam is subjected to the constraint of inner sleeve when motion, less to the condensate liquid influence of move toward one another.The occasion that the present invention can be applied to heat, cooling section does not have obvious difference in height.
The heat exchanger that the present invention forms can be used in the air-conditioning treatment box of air-conditioning system, is used to improve the effect on moisture extraction of surface cooler, and plays energy-conservation effect.
