[0031] A wind-water cooling heat exchanger, such as Figures 1 to 7 As shown, it includes a heat exchanger body 1 and a fan body 2, and the fan body 2 is detachably connected to the heat exchanger body 1; the heat exchanger body 1 includes a shell 18, and a core 19 arranged in the shell 18, a ventilation hole is provided on the shell 18 corresponding to the position of the core 19, and a joint 20 is provided at the end of the core 19 extending out of the shell 18; the fan body 2 includes a base 4, a fan assembly 11 arranged in the base 4, and an air distribution assembly arranged below the base 4 corresponding to the fan assembly 11; an air inlet 12 connected to the ventilation hole is provided on the end of the base 4 facing the shell 18, and an air outlet 13 is provided below the base 4 corresponding to the position of the air distribution assembly.

[0032] Exemplarily, the core 19 can be a coil, and two connectors 20 are provided corresponding to the liquid inlet and liquid outlet of the core 19 , and each connector 20 is welded and fixed to the core 19 , and the core 19 is detachably mounted on the shell 18 .

[0033] In actual application, the shell 18 can adopt a split structure, including a front shell 18 and a rear shell 18. The front shell 18 and the rear shell 18 are both formed by bending or welding sheet metal to form a multi-faceted shell 18 structure. The front and rear shells 18 can be detachably connected by snapping or screws. The front shell 18 or the rear shell 18 is provided with an assembly groove that cooperates with the core 19. The core 19 cooperates with the assembly groove to achieve detachable installation of the core 19 in the shell 18. In addition, those skilled in the art can also choose other ways to detachably install the core 19 on the shell 18 according to actual needs, such as using a clamp or other structure, which will not be repeated here. By detachably installing the core 19 on the shell 18, it is convenient to replace or maintain the core 19 later, which helps to reduce the difficulty of use and maintenance of the heat exchanger body 1.

[0034] Preferably, the fan assembly 11 is detachably mounted on the base 4, and a receiving cavity for receiving the fan assembly 11 is provided in the base 4, and the air outlet 13 and the air inlet 12 are both connected to the receiving cavity; a detachable cover plate 5 is provided at a position corresponding to the receiving cavity on the base 4, and the cover plate 5 is provided with a plurality of threading holes 6 for facilitating threading, and the threading holes 6 are connected to the receiving cavity.

[0035] For example, the fan assembly 11 can be fixed to the base 4 by screws, and the cover 5 can also be fixed to the base 4 by screws. The fan assembly 11 can utilize an existing electric blower or electric fan. Its power supply and control methods are known in the art and will not be described in detail here. The detachable installation of the fan assembly 11 and the cover 5 also facilitates subsequent replacement and maintenance of the fan assembly 11 by the operator, reducing the difficulty of using and maintaining the fan body 2.

[0036] In actual use, the cover plate 5 is positioned on the end of the base 4 that is separate from the housing 18, allowing operators to replace and maintain the fan assembly 11 without removing the base 4. A protective ring 7 is also provided on the cover plate 5 at a position corresponding to the wire hole 6. For example, the protective ring 7 can be a rubber ring that can be snapped onto the cover plate 5 or secured to the cover plate 5 with an adhesive. The protective ring 7 effectively protects the wiring harness of the fan assembly 11 and prevents it from being cut.

[0037] Preferably, the air distribution assembly includes an air guide cover 8, and an air distribution bracket 9 arranged on the air guide cover 8 corresponding to the air outlet 13; the air distribution bracket 9 is provided with a conical end portion 16 at one end facing the air inlet 12, and a plurality of air guide grilles 10 are arranged at intervals on the inclined surface of the conical end portion 16, and there is an air outlet gap between two adjacent air guide grilles 10 that is connected to the air outlet 13.

[0038] Preferably, the air distribution bracket 9 is an inverted V-shaped structural member, and the left and right sides of the air distribution bracket 9 are detachably mounted on the air guide cover 8 through the connecting portion 17, and a plurality of air guide grilles 10 are spaced apart on the two inclined surfaces of the conical end portion 16. The air guide grille 10 includes a vertical section and a horizontal section, and the horizontal section is detachably mounted on the air distribution bracket 9, and the vertical section supports the air guide cover 8. Specifically, two, three or more air guide grilles 10 can be spaced apart, and those skilled in the art can set them as needed. The horizontal end of each air guide grille 10 can be fixed to the air distribution bracket 9 by screws or rivets. By setting the conical end portion 16, air distribution can be achieved, so that the air distribution bracket 9 can discharge air on both sides to meet the cooling needs of the transmitter, and by arranging multiple air guide grilles 10 at intervals, it is also beneficial to improve the uniformity of the cold air.

[0039] In actual use, when the converter needs to dissipate heat, air passes through the core 19 of the heat exchanger body 1, where its temperature drops to form cold air. This cold air then enters the fan assembly 11 through the rear of the base 4 of the fan body 2. The fan assembly 11 transports the cold air to the air outlet 13 at the bottom of the base 4. After passing through the air guide 8, it is discharged from the air distribution bracket 9 to both sides. The air volume on both sides can be adjusted by designing the angle of the tapered end 16 on the air distribution bracket 9. Multiple air guide grilles 10 can also make the air output more uniform. This structure not only reduces the size of the converter but also helps reduce the converter's design cost.

[0040] Preferably, the air scoop 8 includes a left half scoop 14 and a right half scoop 15, wherein the left half scoop 14 and the right half scoop 15 are detachably connected, and both the left half scoop 14 and the right half scoop 15 can be detachably mounted on the base 4. For example, the left half scoop 14 and the right half scoop 15 can be connected by blind rivets, and both the left half scoop 14 and the right half scoop 15 can be fixed to the base 4 by screws or rivets. The split structure of the air scoop 8 facilitates subsequent disassembly and cleaning of the air scoop 8, reducing the difficulty of cleaning the air scoop 8 if it becomes clogged.

[0041] Preferably, the heat exchanger body 1 and the fan body 2 are connected via a connecting bracket 3. Exemplarily, two connecting brackets 3 are provided on the left and right sides of the fan body 2, and each connecting bracket 3 is detachably mounted on the fan body 2 at one end and detachably mounted on the heat exchanger body 1 at the other end.

[0042] In actual use, the connecting bracket 3 is an L-shaped structural member that can be fixed to the housing 18 or base 4 using screws or rivets. Those skilled in the art may also choose other installation methods to achieve detachable mounting of the connecting bracket 3 based on actual needs, which will not be described here. Using two connecting brackets 3 to connect the fan body 2 and the heat exchanger body 1 helps to improve the structural strength of the connection between the fan body 2 and the heat exchanger body 1, ensuring that the fan body 2 can stably cooperate with the heat exchanger body 1 to achieve cooling.

[0043] Preferably, the housing 18 is provided with a bent portion 23 on the top to facilitate assembly, and a raised portion 21 on the bottom to facilitate assembly. Two raised portions 21 are provided, one on each side of the housing 18, and each raised portion 21 is connected to the housing 18 via a reinforcing rib 22. For example, both the bent portion 23 and the raised portion 21 may be provided with mounting holes for bolts to facilitate mounting the air-to-water heat exchanger on a cabinet. The reinforcing rib 22 is fixed to the housing 18 and enhances the structural strength of the housing 18.

[0044] The air-water heat exchanger has the advantages of simple structure, small size, low cost, easy assembly and maintenance, can be suitable for heat exchange and cooling of the current transformer, and is designed based on single-side air inlet and double-side air outlet, so that the volume of the current transformer can be reduced, and the design cost of the current transformer is reduced.

[0045] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
