Problems solved by technology

[0005] In the prior art, it is usually installed inside or outside the equipment or cabinet, which not only has a complex structure and poor reliability, but also occupies a large space for the liquid cooling plate and its accessory parts
In addition, the existing inflatable and stamping-welded liquid-cooled plates are light and thin in structure and high in production efficiency, but their structural strength is low and their load-bearing capacity is weak, so it is difficult to be used as the bottom plate of equipment or equipment shells alone

Embodiment 1

[0059] The inner panel of one of the two adjacent sides is bent toward the plane of the other side to form the inner flange, and the inner panel of the other side has a gap matching the shape of the inner flange. The outer plate of one of the sides is bent toward the plane of the other side to form an outer flange, and the outer plate of the other side has a notch matching the shape of the outer flange.

[0060] Specifically, such as Figure 1~6 , the first gap is the first right angle gap 11 opened at the four corners of the liquid cold plate 100, the first right angle gap 11 has a first side 12 and a second side 13 on both sides, the first side 12 and the liquid cold plate The length direction or width direction of 100 is parallel, the first side 12 is provided with a first square notch 121, one side of the first square notch 121 coincides with the second side 13, and the first square notch 121 is far away from the point of the first side 12 It is the first innermost point ...

Embodiment 2

[0063] All sides are of the same height, and the base surface is flanged in the vacant positions of the sides. The base flanging and the side flanging are spliced ​​together.

[0064] Such as Figure 7-11 , the first gap and the second gap are arranged on the two lengthwise sides of the liquid cooling plate 100, the number of the first gap or the second gap on each side is 2, and the first gap is the first four One of the two inner corners of the first quadrilateral notch 21 is a first right angle, the apex of the first right angle is the first innermost point 4, and the second notch is a second quadrilateral In the notch 22 , one of the two inner corners of the second quadrilateral notch 22 is a second right angle, and the apex of the second right angle is the second innermost point 5 . This embodiment significantly reduces the cutting size of the liquid-cooled plate, which not only reduces material waste, but also can be processed with a rolling mill or a brazing furnace w...

Embodiment 3

[0067] All sides are of the same height, and the base surface is flanged in the vacant positions of the sides. The vacant part where the flanging of the base surface is lower than the side can be filled by the side plate.

[0068] Specifically, such as Figures 12 to 16 , the first gap and the second gap are arranged on the two lengthwise sides of the liquid cooling plate 100, the number of the first gap or the second gap on each side is 2, and the first gap is the first V-shaped Gap 31, the angle between the two sides of the first V-shaped notch 31 is a third right angle, the apex of the third right angle is the first innermost point 4, the second notch is the second V-shaped notch 32, the second V-shaped notch The included angle between the two sides of the notch 32 is the fourth right angle, and the vertex of the fourth right angle is the second innermost point 5. The liquid cooling plate 100 is fixed with folded parts on both sides of the first notch and the second notch....

Abstract

The invention relates to the technical field of heat dissipation equipment, in particular to a bending type liquid-cooled heat dissipation cabinet. The bending type liquid-cooled heat dissipation cabinet comprises a liquid-cooled plate, wherein the liquid-cooled plate comprises an inner plate and an outer plate; a liquid-cooled flow path is arranged between the inner plate and the outer plate; andthe liquid-cooled plate is spliced or bent to form a base surface and at least one side surface of the heat dissipation cabinet. The heat dissipation cabinet or a part of the cabinet body is formed by the liquid-cooled plate, so that the space is utilized efficiently, and the heat transfer performance is strengthened.

Description

technical field [0001] The invention relates to the technical field of heat dissipation equipment, in particular to a bent liquid-cooled heat dissipation cabinet. Background technique [0002] With the rapid development of power electronic equipment and devices towards miniaturization, integration, and high efficiency, device performance and heat dissipation continue to increase, resulting in uneven distribution of heat flux density, extremely high local heat flux density, and heat accumulation in local areas. The problem of local overheating. These problems pose new challenges to the thermal design of power electronic equipment, requiring thermal management systems to meet the requirements of high performance, high compactness, high reliability, and high flexibility. [0003] The liquid cooling plate is a plate radiator with a liquid cooling flow path inside. Through the circulation of coolant in the liquid cooling flow path, heat is taken away from the surface of the liqu...
