Fig. 1 is a schematic structural diagram of a circulating heat dissipation type integrated power supply based on a liquid medium according to an embodiment of the present application. The device comprises a housing 1, a rectifying plate, a cooling liquid and a cooling liquid flow passage 10. The rectifying plate is provided with a plurality of rectifying elements 3 which generate heat during operation, so that the density of the cooling liquid in the area is reduced after absorbing heat, and the cooling liquid circulation is automatically formed in the accommodating cavity.
Specifically, the housing 1 includes a first housing 5 and a second housing 6 disposed opposite to each other. The first housing 5 is substantially hollow and has a rectangular parallelepiped structure with an opening at one side. The second housing 6 is a cover plate adapted to the shape of the opening of the first housing 5. After the first casing 5 is abutted with the second casing 6, the second casing 6 can seal the opening end of the first casing 5, so that a closed accommodating cavity 2 is formed between the first casing 5 and the second casing 6.
Wherein, a plurality of bolt holes are arranged on the first shell 5 and the second shell 6 in an aligned way. When the first shell 5 is in butt joint with the second shell 6, the bolt holes on the first shell 5 are aligned with the bolt holes on the second shell 6 one by one, and at the moment, the first shell 5 and the second shell 6 can be fixedly connected through the connecting bolts 9, so that the first shell 5 and the second shell 6 can be detachably connected.
The rectifying plate is fixedly arranged in the accommodating cavity 2 of the shell 1. A plurality of components are arranged on the rectifying plate. These components include the primary heating element and other elements. In this embodiment, the main heating element is the rectifying element 3. Referring to fig. 3, the rectifying elements 3 are located on the left and right sides of the accommodating chamber 2.
The cooling liquid fills the accommodating chamber 2, and fills the accommodating chamber 2. The cooling liquid is in direct contact with the rectifying element 3 in the accommodating cavity 2, and absorbs heat generated during the working of the rectifying element 3 through heat exchange, so that the cooling effect of the rectifying element 3 is realized. Meanwhile, the cooling liquid can transfer heat to the shell 1 through heat exchange, and then the shell 1 radiates heat to the outside, so that the cooling of the cooling liquid is realized.
Preferably, the heat dissipation efficiency of the housing 1 is improved. A plurality of radiating fins 4 are fixedly arranged on the outer sides of the first shell 5 and the second shell 6. The heat dissipation area of the housing 1 is effectively increased by the heat dissipation fins 4, thereby improving the heat dissipation efficiency of the housing 1.
In addition, a launder 11 communicating with the accommodating chamber 2 is provided inside each heat radiating fin 4. The launder 11 extends in the longitudinal direction of the heat radiating fin 4. The flow grooves 11 not only increase the contact area between the shell 1 and the cooling liquid and improve the heat conduction efficiency between the cooling liquid and the shell 1, but also can flow into the flow grooves 11 and flow along the flow grooves 11 when the cooling liquid flows in the accommodating cavity 2, at the moment, the cooling liquid and the atmosphere outside the shell 1 are separated by only thinner radiating fins, and the cooling liquid and the atmosphere exchange heat through the radiating fins 4, so that the heat exchange principle similar to a plate heat exchanger is formed, and the heat exchange efficiency between the cooling liquid and the outside atmosphere is greatly improved.

Referring to fig. 6, in the present embodiment, the heat radiating fins 4 and the launder 11 are each triangular in cross-sectional shape. The cross-sectional shapes of the heat radiation fins 4 and the launders 11 may be rectangular, semi-elliptical, or the like.
Two flow passage partitions 7 are fixedly installed on the side surface of the first housing 5 facing the second housing 6. Both flow passage partition plates 7 are arranged in the vertical direction. When the first casing 5 is abutted against the second casing 6, the end of the flow passage partition 7 abuts against the inner end surface of the second casing 6. The flow passage partition 7 forms three coolant flow passages 10 extending in the vertical direction in the accommodating chamber 2. And a gap is reserved between the upper end of the flow passage partition plate 7 and the upper end of the accommodating cavity 2, and a gap is reserved between the lower end of the flow passage partition plate 7 and the lower end surface of the accommodating cavity 2, so that the upper end and the lower end of the cooling liquid flow passage 10 are mutually communicated.

The upper end of the flow passage partition 7 is higher than the upper end face of the rectifying element 3, and the lower end of the flow passage partition 7 is lower than the lower end face of the rectifying element 3. A cooling liquid flow passage 10 is formed between the two flow passage partition plates 7, and no rectifying element 3 is arranged in the cooling liquid flow passage.
Referring to fig. 5, the rectifying element 3 is operated with its main heating element generating more heat. The cooling liquid in the housing chamber 2 located near the main heating element absorbs heat of heat dissipation thereof, and the cooling liquid in the portion is warmed up. The liquid coolant after the temperature rise is reduced in density and moves to the upper portion of the housing chamber 2. During the upward movement, heat exchange occurs between the cooling liquid and the casing 1, so that the temperature of the cooling liquid is gradually reduced. After rising a certain distance, it flows over the coolant flow channel 10 located in the middle, then moves downward along the coolant flow channel 10, and finally flows out from the lower end of the coolant flow channel 10 to both sides. Thereby creating two coolant loops within the receiving chamber 2. Through the circulation flow of the cooling liquid, the cooling effect on the rectifying element 3 is effectively improved.
Preferably, a placing cavity 8 for placing the rectifying element 3 is further formed on the inner side of the first housing 5. See fig. 4. The shape of each placement cavity 8 is adapted to the shape of the corresponding site element. By arranging the placing cavity 8, the mounting stability of the rectifying plate can be improved, and the situation that the rectifying element 3 is deviated in position and the like in the assembling process of the shell 1 is avoided.
In addition, a wiring cavity is arranged below the accommodating cavity in the shell. The wiring cavity is separated from the accommodating cavity by a partition plate. An opening is formed in the partition plate, and a sealing gasket is fixedly installed in the opening. Two through holes with smaller diameters are formed in the sealing gasket. The upper end of the switching copper column penetrates through the through hole and then extends into the accommodating cavity, and is electrically connected with the rectifying plate. The lower end of the switching copper column extends into the wiring cavity, so that a circuit in the wiring cavity can be electrically connected with the rectifying plate through the switching copper column. Through the interference fit between switching copper post and the through-hole, realize circuit connection when guaranteeing to seal.
From this, the mounted position of rectifying element and runner baffle is rationally disposed to technical scheme of this application, and density reduces after absorbing heat through the coolant liquid, is holding the intracavity and is automatically forming the coolant liquid circulation, and then further improves the cooling effect that rectifies the element through the coolant liquid circulation and makes the coolant liquid that holds the intracavity flow in order to guarantee the circulation flow of coolant liquid, improve the cooling effect of rectifying element.
