[0015] For example, see Figures 1 to 13 As shown, an air-cooled radiator includes a main box body 10, and a plurality of heat dissipation fans 20 are installed at the rear of the main box body 10; A plurality of heat exchange grooves 31 are formed on the inner side walls of the left and right inner plates 30 of the main box body 10. The inner side walls of the two inner plates 30 are formed with rectangular frame portions at the four edges. The inner horizontal fixing plates 32 are inserted into the rectangular frame portions. The outer side walls of the inner horizontal fixing plates 32 are welded and fixed to the inner side walls of the rectangular frame portions. The corresponding wall surfaces of the inner horizontal fixing plates 32 are pressed against the inner side walls of the inner plates 30 and cover all the corresponding heat exchange grooves 31 on the inner plates 30, thereby dividing all the heat exchange grooves 31 into heat exchange chambers 33. A heat dissipation assembly 40 is fixed on the inner horizontal fixed plate 32 corresponding to the heat exchange cavity 33 , and the heat dissipation assembly 40 is in communication with the corresponding heat exchange cavity 33 ; A central through slot 12 is formed in the middle of the front end plate 11 fixed at the front of the main box body 10 . The central through slot 12 faces all the heat dissipation components 40 between the two inner plates 30 , and all the heat dissipation fans 20 face the central through slot 12 .

[0016] Furthermore, the heat dissipation assembly 40 and the corresponding heat exchange cavity 33 are filled with refrigerant liquid.

[0017] The liquid level of the refrigerant liquid reaches one third to one half of the height of the heat dissipation component 40 and the corresponding heat exchange cavity 33 .

[0018] The heat dissipation assembly 40 includes two horizontal tube bodies 41 extending left and right at the upper and lower parts, and a plurality of vertically extending flat tubes 42 (microchannel flat tubes are used in this embodiment, generally microchannel aluminum flat tubes) with both ends welded and fixed to the upper and lower horizontal tube bodies 41. The corresponding ends of the flat tubes 42 are connected to the corresponding horizontal tube bodies 41, and a heat dissipation fin 43 with a wave-shaped bending extension is welded and fixed between each adjacent two flat tubes 42.

[0019] A liquid filling connector is connected to the middle side plate of a transverse tube body 41 of each heat dissipation assembly 40, and refrigerant liquid can be replenished through the liquid filling connector.

[0020] One end of the two horizontal tubes 41 is formed with an end plate, and the other end is welded and fixed to the inner wall surface of the corresponding inner horizontal fixing plate 32 and communicates with the through hole formed on the corresponding inner horizontal fixing plate 32, and the through hole communicates with the corresponding heat exchange cavity 33.

[0021] The structure of the main box body 10 is as follows: the tops of the two inner plate bodies 30 are fixed to the same upper fixed plate, the inner bottom plate 14 is fixed between the lower parts of the two inner plate bodies 30, the bottom ends of the two inner plate bodies 30 are fixed to the same bottom plate, the rear wall plate is fixed to the rear wall surface of the upper fixed plate and the rear wall surface of the bottom plate, the rear walls of the two inner plate bodies 30 and the inner bottom plate 14 are pressed against the rear wall surface of the rear wall plate, a plurality of blowing holes 15 are formed on the rear wall plate, a plurality of cooling fans 20 are fixed on the rear wall plate of the rear wall plate, the air inlet holes of the cooling fans 20 face the blowing holes 15, a rear cover 16 is fixed to the rear part of the rear wall plate, and all cooling fans 20 are located in the rear cover 16; The upper fixing plate, the bottom plate and the front ends of the two inner plates 30 are fixed to the same front end plate 11 .

[0022] A plurality of air outlet holes 161 are formed on the rear wall of the rear cover 16 , and the air outlet holes 161 face the air outlet of the heat dissipation fan 20 ; The air outlet hole 161 is composed of a plurality of arc-shaped holes. This structure prevents large external objects from entering through the air outlet hole 161.

[0023] Specifically, two inner panels 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 wall panel 11. Two outer panels 17 are pressed against the sidewalls of the rear wall panel, upper fixing plate, bottom plate, and front wall panel 11 at the corresponding side and secured by bolts. An installation cavity is formed between the outer panels 17, the corresponding inner panels 30, and the portions of the rear wall panel, upper fixing plate, bottom plate, and front wall panel 11 extending from the inner panels 30. A control circuit board is disposed within the installation cavity. The control circuit board is secured to the inner panels 30 and located on the outer sidewalls of the inner panels 30 at the corresponding heat exchange chamber 33. The outer wall surface of the electronic components of the control circuit board is tightly secured to the outer wall surface of the corresponding inner panel 30 using thermally conductive adhesive (which is an insulating adhesive).

[0024] A plurality of waist-shaped raised rings 34 are formed on the outer wall from the middle to the rear of the inner plate body 30 on the left side, and all the waist-shaped raised rings 34 are arranged in a runway-shaped heat exchange portion 35. The inner wall of the inner plate body 30 corresponding to the runway-shaped heat exchange portion 35 is formed with a waist-shaped heat exchange groove 31; its runway-shaped heat exchange portion 35 increases its heat exchange area, and the outer wall surface of the electronic components of the corresponding fixed control circuit board is bonded and fixed to the runway-shaped heat exchange portion 35 by thermal conductive glue, thereby achieving a heat conduction effect.

[0025] Furthermore, a plurality of inwardly extending protrusions 36 are formed on the inner wall surface of the waist-shaped heat exchange groove 31, and all the protrusions 36 are evenly distributed on the inner wall surface of the waist-shaped heat exchange groove 31. The corresponding protrusions 36 in the vertical direction are arranged vertically in a row, and all the protrusions 36 form multiple rows. The corresponding protrusions 36 in the transverse direction are arranged horizontally in a row, and all the protrusions 36 form multiple rows. A transverse groove is formed between each two adjacent rows of protrusions 36, and a vertical groove is formed between each two adjacent rows of protrusions 36. The raised portion 36 below the middle of the waist-shaped heat exchange groove 31 is a vertically extending long strip protrusion, and the raised portion above the middle is a cube protrusion, which is one-third the size of the long strip protrusion at the lower part. The upper transverse tube body 41 of the heat dissipation component 40 here is located at the upper part of the waist-shaped heat exchange groove 31, and the lower transverse tube body 41 is located at the lower part of the waist-shaped heat exchange groove 31.

[0026] This layout arrangement makes the flow channels between the lower raised parts 36 fewer than the flow channels between the upper raised parts 36, so that when the refrigerant absorbs heat and vaporizes, it flows upward smoothly, and the upper part has more flow channels, so that the vaporized refrigerant is more evenly distributed in the heat exchange groove 31, ensuring the heat exchange effect.

[0027] Furthermore, a rectangular heat exchange groove 31 is formed on the upper and lower portions of the inner side wall of the front portion of the left inner plate 30, and a plurality of second protrusions 37 are formed on the inner wall surface of the heat exchange groove 31. All the second protrusions 37 are distributed throughout the rectangular heat exchange groove 31. A plurality of rectangular heat exchange grooves 31 are formed on the entire inner wall surface of the inner plate 30 on the right side. A plurality of second protrusions 37 are also formed on the inner wall surfaces of all heat exchange grooves 31. All second protrusions 37 are evenly distributed on the entire inner wall surface of the corresponding heat exchange grooves 31. In all rectangular heat exchange grooves 31, the corresponding second protrusions 37 in the vertical direction of each heat exchange groove 31 are arranged vertically in a row, and all the second protrusions 37 form multiple rows. The corresponding second protrusions 37 in the transverse direction are arranged horizontally in a row, and all the second protrusions 37 form multiple rows. A transverse groove is formed between the second protrusions 37 in each adjacent row, and a vertical groove is formed between the second protrusions 37 in each adjacent row. In the rectangular heat exchange groove 31, the second raised portion 37 below the middle is a vertically extending long strip protrusion, and the raised portion above the middle is a cube protrusion, which is one-third the size of the long strip protrusion at the lower part. The upper transverse tube body 41 of the heat dissipation component 40 here is located at the upper part of the waist-shaped heat exchange groove 31, and the lower transverse tube body 41 is located at the lower part of the waist-shaped heat exchange groove 31.

[0028] This structure has the same effect as the above-mentioned protrusion 36 and will not be described in detail here.

[0029] Furthermore, the heat dissipation component 40 forms an angle of 60 to 80 degrees with the air inlet end of the horizontal plane, and in this embodiment it is 70 degrees. This inclination angle allows the length of the heat dissipation component 40 that can be installed to be lengthened when the wind flows and exchanges heat with the heat dissipation component 40 compared to the vertical setting, thereby increasing the heat exchange area and improving its heat dissipation effect.

[0030] Furthermore, the second protrusions 37 on both sides of the middle to upper portion of the rectangular heat exchange groove 31 are cylindrical, and their cross-sectional area is larger than that of the surrounding second protrusions 37, and the corresponding wall surfaces of the adjacent and close second protrusions 37 are arc-shaped wall surfaces; This structure improves the turbulent flow effect of the refrigerant vapor flowing upward.

[0031] When in use, the control circuit board is fixed to the outer wall of the corresponding inner plate 30 by bolts, and the corresponding wall surface of the electronic components on it is bonded and fixed to the outer wall of the corresponding inner plate 30 by thermal conductive glue; During use, when the electronic components of the control circuit board are running, they will generate heat. The heat is conducted to the refrigerant liquid in the corresponding heat exchange groove 31 through the inner plate body 30, causing it to vaporize. The vaporized refrigerant flows upward and fills the entire heat exchange groove 31. At the same time, part of the refrigerant vaporizes and flows along the corresponding flat tube 42 to fill the upper horizontal tube body 41. At this time, the heat dissipation fan 20 draws air, causing the external air to enter the heat dissipation assembly 40 and the inner plate body 30 between the two inner plate bodies 30, and exchange heat with them, causing the refrigerant inside to liquefy and fall, and the gas after heat exchange is discharged from the air outlet hole 161.

[0032] The liquefied refrigerant absorbs the heat of the electronic components, vaporizes again, and is dissipated by the heat dissipation fan 20, and then liquefies and descends again, and this cycle repeats, thereby achieving the heat dissipation and cooling effect on the electronic components of the control circuit board, with good heat dissipation and cooling effect and high heat exchange efficiency.

[0033] The above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. Ordinary technicians in the relevant technical field may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the present invention. The scope of patent protection of the present invention should be defined by the claims.
