DC-DC module power supply liquid cooling passage

[0025] The present invention will be further described below in conjunction with the drawings, but the protection scope of the present invention is not limited to the following.

[0026] Such as figure 1 , figure 2 with image 3 As shown, the DC-DC module power supply liquid cooling channel includes a power housing 1, a liquid inlet 2, a channel body, a liquid outlet 6, and a cover plate 10. The power housing 1 is a plate structure, and the side walls of the power housing 1 are symmetrical A liquid inlet 2 and a liquid outlet 6 are opened longitudinally, and a channel body is opened on the front of the power supply housing 1 from the liquid inlet 2 to the liquid outlet 6, and the channel body includes a liquid cooling channel front section 3 and a liquid cooling channel that are connected to each other The two side walls of the middle section 4 and the rear section 5 of the liquid cooling channel, the front section 3 of the liquid cooling channel and the rear section 5 of the liquid cooling channel are respectively provided with slow flow plates B8, and the two side walls of the middle section 4 of the liquid cooling channel are respectively provided with slow flow Plate A7, cover plate 10 covers the liquid cooling channel formed by the liquid inlet 2, the front section 3 of the liquid cooling channel, the middle section 4 of the liquid cooling channel, the rear section 5 of the liquid cooling channel and the liquid outlet 6, and passes through the power supply housing 1. The welding layer 9 is welded and fixed;

[0027] Such as Figure 4 As shown, the self-locking connector includes a female head 11 and a male head 12, the two female heads 11 are respectively connected with the liquid inlet 2 and the liquid outlet 6 through a threaded fit, and the female head 11 is provided with a self-locking structure, The male head 12 and the female head 11 are matedly connected.

[0028] The ends of the slow flow plate A7 are of semi-cylindrical structure and are alternately staggered and arranged on both sides of the middle section 4 of the liquid cooling channel; the ends of the slow flow plate B8 are of cylindrical structure and are alternately staggered and arranged in the liquid cooling channel. On the two side walls of the front section 3 and the rear section 5 of the liquid cooling channel.

[0029] The power supply housing 1 is made of aluminum, aluminum alloy or aluminum-magnesium alloy.

[0030] The welding method of the cover plate and the power supply housing 1 is argon arc welding, brazing or laser welding.

[0031] The cross section of the channel body is rectangular, and the aspect ratio is 2:1.

[0032] The working process of the present invention is as follows: the cooling liquid enters the front section 3 of the liquid cooling channel, the middle section 4 of the liquid cooling channel and the rear section 5 of the liquid cooling channel from the liquid inlet 2 in sequence, and finally flows out from the liquid outlet 6, at the slow flow plate B8 and the slow flow The slow flow of the plate A7 makes the cooling liquid flow forward in a meandering manner, extending the flow distance of the cooling liquid, so that the cooling liquid can achieve the best heat dissipation effect in the narrower liquid cooling channel. Moreover, the ends of the slow flow plate A7 and the slow flow plate B8 are semi-cylindrical and cylindrical surfaces, so that the cooling liquid encounters the resistance of the slow flow plate A7 and the slow flow plate B8, and the fluidity of the cooling liquid is enhanced.

[0033] When connecting with the outside, before the female head 11 and the male head 12 are butted, the male head 12 and the female head 11 are butted after positioning through the positioning pin and the positioning hole. During separation, while the male head 12 is withdrawn from the female head 11, the self-locking structure provided inside the female head 11 realizes automatic locking and prevents the coolant from flowing out.
