Instead, this flow direction, its heat transfer effect and efficiency are more preferable
Further, the housing is cylinder shell, and housing sidewall front end is provided with heat conducting pipe main entrance, housing sidewall
End is provided with heat conducting pipe general export, and the heat conducting pipe main entrance and heat conducting pipe general export are respectively communicated with corresponding each heat conducting pipe
Both ends, the housing forward end face are provided with heat exchanger tube leakage fluid dram, and end face is provided with heat exchanger tube inlet, the heat exchanger tube row thereafter
Liquid mouth and heat exchanger tube inlet are respectively communicated with heat exchanger tube both ends.
Further, the heat conducting pipe main entrance and heat conducting pipe general export are more siphunculus, including with heat conducting pipe quantity pair
The multiple interfaces answered, and a general export or a main entrance.
The beneficial effects of the utility model are as follows：
(1) such heat exchanger, several grooves being set by the outer wall in heat exchanger tube, each groove inner close fitting has heat conducting pipe,
Both the contact area between heat exchanger tube and heat conducting pipe had been increased, and the heat exchange efficiency of heat exchanger had been improved, with because of liquid（Such as：Water is other
Heat transferring medium）Flowed along heat exchanger tube, heat transferring medium flows along heat conducting pipe, is separate pipe between heat exchanger tube and heat conducting pipe
Road, heat conducting pipe and heat exchanger tube abut, realize that heat quickly transmits between heat conducting pipe and heat exchanger tube, due to heat exchanger tube and heat conduction
Pipe is independent tubes, and any pipeline breaking nor affects on remaining pipes work, improves the stability of its work, effectively prevents from changing
Pollution caused by thermal medium leaks, the practicality of heat exchanger is greatly improved, be especially suitable for heat-pump apparatus field and use.
