[0005] To solve the above technical problems, the technical scheme adopted by the utility model is: a heat exchange pipe fixing device, comprising outer heat exchange pipes and inner heat exchange pipes, a plurality of strap fixing devices for fixing the outer heat exchange pipes and the inner heat exchange pipes are installed between the outer heat exchange pipes and the inner heat exchange pipes, the strap fixing device comprises a strap body and a strap head matched with the strap body, a plurality of first clamping grooves are processed on the strap body, and a second clamping groove is processed on the strap head.

[0006] Preferably, the heat exchange pipe fixing device, wherein the end of the outer heat exchange pipe is provided with a refrigerant inlet, and the end of the inner heat exchange pipe is provided with a refrigerant outlet.

[0007] Preferably, the heat exchange pipe fixing device, wherein a rack is processed on one side outer wall of the strap body, and a lock catch for locking the rack is processed in the strap head.

[0008] The utility model has the advantages and beneficial effects that: through installing a plurality of ribbon fixing devices between the outer heat exchange pipe and the inner heat exchange pipe, the outer heat exchange pipe and the inner heat exchange pipe are clamped through the first clamping groove and the second clamping groove respectively, then the tightness is adjusted through the rack and the ribbon head, the outer heat exchange pipe and the inner heat exchange pipe can be better isolated and fixed, breakage between the outer heat exchange pipe and the inner heat exchange pipe due to friction is effectively prevented, and the structure is simple and convenient to use.
