Embodiment Construction

[0013] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] Such as figure 1 , 2 1. The water-cooled radiator with uniform heat dissipation shown in 3 includes a cuboid radiator body 1, a water inlet 2 and a water outlet 3 arranged on the radiator body 1, wherein the water inlet 2 and 3 are arranged on the same surface On: connect the water inlet 11 arranged inside the radiator body 1 with the water inlet 2, connect the water outlet 12 arranged inside the radiator body 1 with the water outlet 2, wherein the water inlet 11 is parallel to the water outlet 12; vertically connect the water inlet 11 and There are four heat exchange channels 13 in the water outlet channel 12; the cross-sectional area of ​​the heat exchange channel 13 becomes smaller as it gets closer to the water inlet 2 and the water outlet 3 ends. The main body of the heat exchange channel 13 is a water channel in a cylindrical ca...

Abstract

The invention discloses a water-cooling heat dissipater capable of realizing uniform heat dissipation, and belongs to the field of water-cooling heat dissipaters. Aiming at the problems of different flows and different heat exchange amounts of cooling fluid or water due to different resistances caused by different distances from a heat exchange water way to a water inlet and to a water outlet, the invention is based on the following scheme: the water-cooling heat dissipater capable of realizing uniform heat dissipation comprises a cuboid heat dissipater body, the water inlet and the water outlet which are formed in the heat dissipater body, a water inlet way which is connected with the water inlet and is arranged in the heat dissipater body, a water outlet way which is connected with the water outlet and is arranged in the heat dissipater body, and a plurality of heat exchange water ways perpendicularly connected with the water inlet way and the water outlet way; the end of each heat exchange water way is closer to the water inlet and the water outlet, and the sectional area of the end is smaller; and by the adjustment of the sectional area of each heat exchange water way, the heat exchange amounts of all the heat exchange water ways can tend to be consistent, and a heat exchanger is more uniform in overall heat exchange.

Description

technical field [0001] The invention belongs to the field of water-cooled radiators, in particular to a water-cooled radiator with uniform heat dissipation. Background technique [0002] IGBT module, Insulated Gate Bipolar Transistor, is a compound fully controlled voltage-driven power semiconductor device composed of BJT (Bipolar Transistor) and MOS (Insulated Gate Field Effect Transistor), applied to DC voltages of 600V and above Converter systems such as AC motors, frequency converters, switching power supplies, lighting circuits, traction drives and other fields; IGBT modules generate a lot of heat during operation, which requires radiators to dissipate heat. [0003] Chinese invention patent "copper water-cooled radiator", announcement number CN201788963U, announcement date 2011-04-06, discloses a water-cooled radiator, including a cuboid radiator body, a water inlet and a water outlet arranged on the radiator body , the water inlet connected to the water inlet arrange...
