Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: See Figures 1 to 6 A novel air-conditioning heat exchanger comprises: a heat exchange component 2 and a cross arm 11 installed in a chassis 1; the heat exchange component 2 comprises a connecting seat 23 and a group of heat exchangers 21, a group of positioning seats 231 are arranged on both sides of the upper end of the connecting seat 23, a pair of the heat exchangers 21 are respectively inserted between the corresponding positioning seats 231, and a limited edge 211 is also arranged on the heat exchanger 21, and the limited edge 211 is distributed on both sides of the positioning seat 231; a clamping mechanism 4 is arranged between the cross arm 11 and the heat exchange component 2, and is used to fix the heat exchange component 2; a fixing mechanism 3 is arranged between the chassis 1 and the heat exchange component 2, and is used to fix the heat exchange component 2 to the chassis 1.

[0026] The working principle of the utility model is as follows: by setting up a group of heat exchangers 21, when a certain heat exchanger 21 fails to work normally, it will not affect the normal use of the computer room air conditioner. The heat exchange component 2 is fixed by the clamping mechanism 4 in cooperation with the fixing mechanism 3. The operation is simple and the heat exchanger 21 can be conveniently disassembled and replaced, which can better meet the use requirements.

[0027] As a further solution, a positioning chamfer 232 is further provided at the upper end of the positioning seat 231, and a reinforcing connecting piece 22 is further provided between a pair of the heat exchangers 21. The end of the reinforcing connecting piece 22 is fixedly connected to the corresponding limiting edge 211, and the heat exchanger 21 is arranged at an angle.

[0028] A pair of tilted heat exchangers 21 can increase the contact area between the heat exchanger 21 and the air, thereby improving the heat exchange effect of the computer room air conditioner and better meeting the use requirements. The strengthening connecting piece 22 can improve the connection strength between the heat exchangers 21;

[0029] During installation, first insert the heat exchanger 21 between the positioning seats 231, and then fix the heat exchanger 21 and the positioning seats 231 with bolts.

As the clamping protrusion 42 extends into the clamping groove 43, the clamping strip 41 deforms inward. When the clamping protrusion 42 passes through the installation groove 43, the clamping strip 41 is reset, so that the clamping protrusion 42 is buckled under the cross arm 11, and the fixation is completed.
