Compact heat exchanger with hexagonal spiral channels

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] The material of the hexagonal spiral channel compact heat exchanger of the present invention can be metal or non-metal material. The working process of the compact heat exchanger is as follows: the cold fluid enters the heat exchanger from the outer tube 1, passes through the cold air distribution chamber 2 and then enters the cold fluid inner channel 5, and exchanges heat with the hot fluid inner channel 4 through the rotating part in the middle of the heat exchanger. Afterwards, it is discharged from the cold fluid outer pipe 8 through the cold fluid distribution cavity. At the same time, the hot fluid enters the heat exchanger from the hot fluid outer pipe 6, enters the hot fluid inner channel 4 after passing through the hot fluid distribution chamber 7, exchanges heat with the cold fluid in the middle of the heat exchanger, and passes through the hot
