Preferably, the inclination angle β is 3 degrees or 6 degrees. This scheme can make the coolant liquid that remains in nest of tubes inside discharge away better through certain suitable inclination's transport nest of tubes, forms the evacuation freeze-proof environment.

Preferably, the conveying pipe groups are selected from 2-5 groups. This scheme can increase cooling mobility and area through certain suitable number delivery nest of tubes for the cooling effect obtains further improving, has improved cooling efficiency simultaneously.

Preferably, the first circulation pipe is located at the upper end of the conveying pipe group, and the second circulation pipe is located at the lower end of the conveying pipe group and is located on a different vertical line from the first circulation pipe. The scheme can lead the circulating cooling liquid to flow more smoothly and stably through the proper positions of the first circulating pipe and the second circulating pipe, and simultaneously lead the speed of the residual cooling liquid to be increased.

Preferably, the connector is a grooved pipe fitting. This scheme can make two liang of conveying nest of tubes connect more stably through the slot pipe fitting to it is convenient fast to dismantle, convenient follow-up ground is maintained.

Preferably, the connector is inclined at an angle of 20-45 degrees with respect to a line along which the width of the frame is located, and is connected with every two adjacent conveying pipe sets. This scheme can make other transport nest of tubes remaining coolant liquid can carry the emission better through the connector of certain connection inclination, ensures the inside evacuation state that forms of heat exchanger.

Preferably, at least two openings are fixed on the front surface of the bottom of the frame. This scheme can increase heat circulation speed through a plurality of trompils, improves heat transfer refrigerated speed and efficiency.

Has the advantages that: after the structure of the utility model is adopted, because the structure is provided with the first circulating pipe, the second circulating pipe, the frame and at least one conveying pipe group, the inclination angle beta 3-8 between every two conveying pipe groups is fixed on the frame, and the connector is in inclined connection of 30 degrees, the cooling liquid in the cooling pipe is emptied by standing and inclining, thereby avoiding frostbite caused by over-low external temperature; and then obtain rational in infrastructure, can fast and stably heat transfer to can also empty and prevent frostbite the formula and carry out the protection of stewing, long service life's anti-freezing heat exchanger.
