The working medium flow channel 11 and working medium flow pass 12 of axis setting, the working medium in working medium flow channel 11 and working medium flow pass 12
Flow direction is opposite to form convection current, and the coaxial design of working medium flow channel 11 and working medium flow pass 12, so that the suction on tube wall
Hot fin 2 and the intracorporal working medium flow channel 11 of pipe and the equal equidistant placement of working medium flow pass 12, and increase inflow working medium
The heat exchange area between outflow working medium, so that managing, intracorporal working medium heat exchange is more abundant, and heat absorption is more uniform.With it is existing
There is technology to compare, required working medium amount is greatly decreased under same endotherm area, reduces working medium cost；Working medium access is shortened,
Reduce the flow resistance of working medium；The flow cycle for shortening refrigeration oil, avoid due to oil circuit it is too long caused by unit return
Oil it is difficult and in turn caused by compressor fault；Material cost needed for being repaired under heat area on an equal basis is lower, and processing is more convenient, weight
It measures lighter.
Working medium flow channel 11 is preferably co-axially located in working medium flow pass 12, so that working medium flow pass 12 is located at work
Between matter flow channel 11 and the closing of tube body 1, tube body 1 is followed successively by heat absorbing fins 2, tube wall, working medium flow pass from outside to inside
12, working medium flow channel 11.On the one hand, working medium flow pass 12 is closely equipped with the tube wall of heat absorbing fins 2, enables to effuser
The working medium of body 1 is sufficiently absorbed heat；On the other hand, working medium flow channel 11 is co-axially located in working medium flow pass 12, is flowed into
Working medium can absorb the heat of outflow working medium and be heated, the heat absorption of working medium in tube body 1 is more full and uniform；And due to work
Matter flow channel 11 is located at 1 axle center of tube body, and section is solid close-shaped, and working medium flow pass 12 is due to being located at work
Between matter flow channel 11 and tube wall, interface is cyclic annular, under identical section traffic conditions, the thickness of working medium flow pass 12
It is relatively thin, it is exchanged so that it is able to carry out sufficient heat with the tube wall of the working medium flow channel 11 of inside and outside.
Working medium flow pass 12 includes the equally distributed multiple working medium outflow subchannels of outer wall in working medium flow channel 11
121.The multiple demarcation plates 122 that can be disposed radially in working medium flow pass 12, demarcation plate 122 is by working medium flow pass 12
It is divided into multiple working medium outflow subchannels 121.As shown in Fig. 2, being radially arranged in the working medium flow pass 12 of the present embodiment
