The corresponding wall surface of the electronic components of the control circuit board is in close contact with the outer wall of the inner plate. Through the heat absorption and expansion of the refrigerant, the heat of the electronic components on the control circuit board is quickly absorbed and cooled by the air blown by the cooling fan, thereby rapidly cooling the electronic components. It has a good cooling effect, fast cooling and good effect.

[0026] For example, see below. Figures 1 to 9 As shown, an integrated air-cooled radiator includes a main housing 10, and a plurality of cooling fans 20 are installed at the rear of the main housing 10.

[0027] The inner walls of the left and right inner side plates 30 of the main housing 10 are each formed with a plurality of vertically extending elongated grooves 31. Each elongated groove 31 has a rearwardly extending side passage 32 on its rear side wall, which communicates with the adjacent elongated groove 31 behind it. In each pair of adjacent elongated grooves 31, the side passage 32 of the preceding elongated groove 31 is located at the upper part, and the side passage 32 of the following elongated groove 31 is located at the lower part, or the side passage 32 of the preceding elongated groove 31... The side through groove 32 of the groove 31 is located at the bottom, and the side through groove 32 of the next elongated groove 31 is located at the top. All the side through grooves 32 are intersected. The side through grooves 32 of the two corresponding elongated grooves 31 on the left and right sides of the two inner side plates 30 are also intersected. That is, the side through groove 32 of the elongated groove 31 on the left is located at the top, and the side through groove 32 of the elongated groove 31 on the right is located at the bottom, or the side through groove 32 of the elongated groove 31 on the left is located at the bottom, and the side through groove 32 of the elongated groove 31 on the right is located at the top.

[0028] An intermediate heat exchange assembly 40 is provided between two corresponding elongated grooves 31 on the left and right sides of the two inner side plates 30. The two connecting end plates 41 of the intermediate heat exchange assembly 40 are welded and fixed to the inner wall surface of the corresponding inner side plates 30 and cover the corresponding elongated grooves 31. The heat exchange pipe 42 of the intermediate heat exchange assembly 40 is connected to the corresponding two elongated grooves 31.

[0029] The front fixed front end plate 11 of the main housing 10 has a central through groove 12 formed in the middle. The central through groove 12 faces all the intermediate heat exchange components 40 between the two inner side plates 30. All the intermediate heat exchange components 40 face the central through groove 12. The air inlet of the cooling fan 20 faces the central through groove 12.

[0030] Furthermore, both the intermediate heat exchange component 40 and the elongated groove 31 are filled with refrigerant liquid.

[0031] Furthermore, the intermediate heat exchange assembly 40 includes a plurality of horizontally extending heat exchange tubes 42 arranged vertically. The heat exchange tubes 42 are microchannel flat tubes, and their left and right parts are locked in the corresponding waist-shaped through grooves formed on the two connecting end plates 41 and welded and fixed. The ends of the heat exchange tubes 42 extend out of the corresponding wall surface of the connecting end plates 41 and extend into the corresponding elongated grooves 31.

[0032] A corrugated heat exchange fin 43 is welded and fixed between every two adjacent heat exchange tubes 42.

[0033] Furthermore, an upper connecting plate is fixed to the top surface of the topmost heat dissipation fin 43 of each intermediate heat exchange component 40, and a lower connecting plate is fixed to the bottom surface of the bottommost heat dissipation fin 43.

[0034] Furthermore, at least one elongated groove 31 has an outwardly extending punching connection through hole 1 formed on its inner wall surface, which can be connected to a supplementary connector. The refrigerant liquid can be punched into the corresponding elongated groove 31 through the punching connection through hole 1. The refrigerant liquid can be punched into the total volume of all elongated grooves 31 and the heat exchange tubes 42 of the intermediate heat exchange assembly 40, thereby allowing the refrigerant liquid to have enough space to absorb heat, expand and vaporize.

[0035] Furthermore, the main housing 10 has the following structure: the tops of the two inner side panels 30 are fixed with the same upper fixing plate; an inner bottom plate 14 is fixed between the lower parts of the two inner side panels 30; the bottom ends of the two inner side panels 30 are fixed with the same bottom plate; the rear wall panel is fixed on the rear wall surface of the upper fixing plate and the rear wall surface of the bottom plate; the rear wall surfaces of the two inner side panels 30 and the inner bottom plate 14 are pressed against the rear wall surface of the rear wall panel; multiple air blowing holes 15 are formed on the rear wall panel; multiple cooling fans 20 are fixed on the rear wall panel; the air inlets of the cooling fans 20 face the air blowing holes 15; a rear cover 16 is fixed to the rear part of the rear wall panel; and all the cooling fans 20 are located in the rear cover 16.

[0036] The front ends of the upper fixing plate, the bottom plate, and the two inner side plates 30 are fixed to the same front end plate 11.

[0037] Furthermore, the rear wall panel of the rear cover 16 is formed with a plurality of air outlet holes 161, which are aligned with the air outlet of the cooling fan 20.

[0038] The air outlet 161 is composed of multiple arc-shaped through holes.

[0039] Furthermore, two inner side plates 30 extend from the left and right sides of the rear wall panel, the left and right sides of the upper fixing plate, the left and right sides of the bottom plate, and the left and right sides of the front end plate 11. Two outer side plates 17 press against the side walls of the rear wall panel, upper fixing plate, bottom plate, and front end plate 11 on the corresponding side and are fixed with bolts. An installation cavity is formed between the outer side plate 17 and the corresponding inner side plate 30 and the portion of the rear wall panel, upper fixing plate, bottom plate, and front end plate 11 extending from the inner side plate 30. In use, the control circuit board is placed in the installation cavity and fixed to the outside of the corresponding inner side plate 30. The corresponding wall surfaces of the electronic components of the control circuit board are fixed to the outer side walls of the corresponding inner side plate 30 with thermally conductive adhesive to improve its heat conduction effect.

[0040] When in use, the electronic components on the control circuit board generate heat during operation. This heat is conducted through the inner plate 30 to the refrigerant liquid in the corresponding elongated groove 31 and the refrigerant liquid in the heat exchange tube 42, causing it to absorb heat and vaporize. The vaporized refrigerant flows upward and fills the entire elongated groove 31. At this time, the cooling fan 20 draws in air, allowing external air to enter the heat dissipation component 40 and the inner plate 30 between the two inner plates 30, where it exchanges heat with them. This causes the refrigerant inside to liquefy and fall, and the gas after heat exchange is discharged from the air outlet 161.

[0041] The liquefied refrigerant absorbs heat from the electronic components, vaporizes again, and is then cooled by the cooling fan 20, liquefying and descending again. This process repeats, thereby achieving the effect of cooling the electronic components on the control circuit board. It has a good cooling effect and high heat exchange efficiency.

[0042] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model, and the patent protection scope of the present utility model should be defined by the claims.
