Detailed Description

The utility model is further described below with reference to the drawings and examples.

Referring to fig. 1-5, a heat exchange device for a cooling fan includes a frame 10, a plurality of heat exchange fins 20 for conveying heat exchange liquid are transversely arranged in the frame 10, the heat exchange fins 20 are arranged in a wave shape, a water inlet pipe 210 and a water outlet pipe 220 which are communicated with the inside are arranged on the heat exchange fins 20, the water inlet pipe 210 and the water outlet pipe 220 in adjacent heat exchange fins 20 are connected with each other by adopting a connecting pipe fitting 230, the water inlet pipe 210 of the heat exchange fin 20 at the head end is connected with an external water tank 30, and the water outlet pipe 220 of the heat exchange fin 20 at the tail end is connected with the external water tank 30.

Specifically, the heat exchange fins 20 are arranged laterally. When the air flows from back to front, the air flow speed is weakened when the heat exchange fins 20 are arranged in a wave shape, so that the air contacts with the heat exchange fins as much as possible, the heat exchange efficiency is improved, and the use requirement of a user is met.

Referring to fig. 2 and 3, the heat exchange fin 20 is provided with a mounting ear seat 200, and the mounting ear seat 200 is fixedly mounted on the frame 10 by using a fastener.

Specifically, the fastener adopts a bolt. At the time of assembly, the heat exchange fins 20 are put into the frame 10 and moved to the installed position, and then screwed with the frame 10 through the installation lugs 200 using bolts.

Referring to fig. 3, the water inlet pipe 210 and the water outlet pipe 220 located in the same heat exchange fin 20 are disposed diagonally to each other. The diagonally arranged water inlet pipe 210 and water outlet pipe 220 can enable heat exchange liquid to flow in from one corner of the heat exchange fin 20 and then flow out from the opposite corner, so that the whole heat exchange fin 20 is filled with the heat exchange liquid, and the heat exchange efficiency is fully ensured.

Referring to fig. 2, the heat exchanging fin 20 is composed of a plurality of heat exchanging parts 240 connected in sequence, and each heat exchanging part 240 is hollow and is communicated with each other in sequence; the included angle between two adjacent heat exchange parts 240 is A; a is more than 0 DEG and less than 180 deg.

The included angle A is more than 0 degrees and less than 180 degrees. The function is as follows: the adjacent heat exchange parts 240 are not positioned on the same plane, so that the flow velocity of the air is reduced when the air flows, the contact time of the air and the heat exchange fins 20 is increased, and the heat exchange efficiency is improved.
