The second fixing rod 3 is provided with a second slot 5, which penetrates the upper and lower sides of the second fixing rod 3 and extends along the length direction of the second fixing rod 3.

[0036] A plurality of heat absorbing components, wherein the plurality of heat absorbing components are mounted on the first fixing rod 2 and the second fixing rod 3, and the heat absorbing components are sequentially arranged along the length direction of the first fixing rod 2, and the heat absorbing components include two heat absorbing members 6, and the two heat absorbing members 6 are respectively arranged on the upper and lower sides of the heat exchange tube 1, and the heat absorbing member 6 includes a heat absorbing half ring 7 and a heat absorbing sheet 8 fixed on the heat absorbing half ring 7, and a first plug block 9 and a second plug block 10 are respectively fixed at both ends of the heat absorbing half ring 7, and the first plug block 9 is plugged into the first slot 4, and the second plug block 10 is plugged into the second slot 5;

[0037] The limiting device includes a limiting state and an unlocking state. In the limiting state, the limiting device limits the first plug-in block 9 in the first slot 4. In the unlocking state, the limiting device releases the limiting of the first plug-in block 9.

[0038] When it is observed that the heat absorption sheet 8 on a certain heat absorption component 6 is damaged, it is only necessary to adjust the limiting device to the unlocked state, and the limiting device releases the limit on the first plug block 9. At this time, the first plug block 9 can be moved out of the first slot 4, and the second plug block 10 can be moved out of the second slot 5. The damaged heat absorption sheet 8 can be removed, and then the first plug block 9 of the new heat absorption component 6 is plugged into the first slot 4, and the second plug block 10 is plugged into the second slot 5. Then the limiting device limits the first plug block 9 in the first slot 4, and the new heat absorption component 6 is replaced. Only a single heat absorption component 6 needs to be replaced, and there is no need to replace the entire heat exchanger, which is low in cost.
