[0030] refer to Figures 1-6 As shown, in the embodiment of the present invention, a water cooling unit is proposed, which is mainly used for agricultural machinery or other mechanical equipment operating in harsh environments. The water cooling unit includes a box body 1, a ceiling 2 and a cooling module. The box body 1 is provided with a accommodating cavity. The top surface of the box body 1 is also provided with a first ventilation hole 14 connecting the accommodating cavity with the outside world. One side of the box body 1 is also provided with a second ventilation hole connecting the accommodating cavity with the outside world. The cooling module includes a compressor, an evaporator, a condenser 10 and a blower fan 3. The compressor, evaporator and condenser 10 are all located in the accommodating cavity. The blower fan 3 is provided on the side of the box body 1 and covers the second ventilation hole to dissipate the hot air formed in the accommodating cavity. Exhaust, the ceiling 2 is set on the top of the box body 1, and includes a support member 21 and a shielding member 22, wherein the support member 21 is fixed on the top surface of the box body 1, and is used to stably support the shielding member 22, so that the shielding member 22 is located above the top of the box body 1 and shields the box body 1. It should be emphasized that the upper and lower ends of the surface of the support member 21 on the same side as the blower fan 3 are respectively attached to the shielding member 22 and the box body 1, so as to prevent the hot air blown out by the blower fan 3 from entering the accommodating cavity through the support member 21 and affecting the heat dissipation effect of the water-cooled unit.

[0031] The above-mentioned water-cooling unit can reduce the possibility of rainwater and dirt entering the box body 1 through the first ventilation hole 14 by arranging a ceiling 2 above the box body 1, thereby reducing the possibility of the water-cooling unit being blocked in a sunny, rainy or dirty working environment; at the same time, it can prevent the temperature inside the accommodating cavity from rising due to direct sunlight on the box body 1, thereby improving the working efficiency of the water-cooling unit; and the ceiling 2 and the blower fan 3 are located on the same side of the closed surface arrangement, which can prevent the hot air blown out by the blower fan 3 from entering the accommodating cavity again, affecting the heat dissipation effect of the water-cooling unit.

[0032] In one embodiment, in order to further improve the effect of preventing hot air from re-entering the box body 1, the support member 21 also has two second closed surfaces located at opposite ends of the first closed surface. The second closed surfaces are arranged at an angle to the first closed surface and extend toward the side of the box body 1 away from the blower fan 3. The upper and lower ends of the second closed surfaces are respectively attached to the shielding member 22 and the box body 1.

[0033] Specifically, refer to Figure 1 As shown, the support member 21 includes a support frame 211 and a sealing plate 212. The support frame 211 is configured as a cubic frame with openings on all six sides. A sealing plate 212 is secured to the side surface on the same side as the blower fan 3, while two adjacent side surfaces are also secured to the sealing plate 212. The sealing plate 212 located on the same side as the blower fan 3 is the first sealing surface, while the two adjacent sealing plates 212 are the second sealing surfaces. Of course, the sealing plate 212 can also be located only on the same side of the support frame 211 as the blower fan 3.

[0034] In order to prevent dirt or rainwater from entering the inner side of the support member 21 through the support frame 211 and then entering the box body 1 through the first ventilation hole 14, the shielding member 22 covers the support member 21 with its positive projection toward the side of the support member 21.

[0035] In one embodiment, referring to Figure 2 and Figure 3 As shown, the shielding member 22 includes a main body 221 and a guide portion 222, wherein the main body 221 is fixed to the top surface of the support member 21 and is parallel to the top surface of the box body 1 under the support of the support member 21. The guide portion 222 is annularly arranged on the outer periphery of the main body 221, and has a guide surface on the side facing away from the support member 21 that gradually slopes downward from the side connected to the main body 221 to the other side, so that rainwater or dirt can roll off or fall off the shielding member 22 in a timely manner, reducing the possibility of accumulation on the shielding member 22. It is understandable that the specific shape of the annular guide portion 222 is adapted to the shape of the box body 1. For example, when the box body 1 is configured as a rectangle, the main body 221 is also configured as a rectangle, while the guide portion 222 is configured as a square ring.

[0036] In other embodiments, the shielding member 22 may also be configured as a conical structure.

[0037] Optionally, the housing 1 includes a main housing 11 and a mounting plate 12, wherein the main housing 11 is configured as a rectangular trough structure with one side open. The mounting plate 12 is removably mounted on the main housing 11 using methods including but not limited to bolting and snap-fitting to seal the opening and form a receiving cavity with the main housing 11. The condenser 10 and the blower fan 3 are both mounted on the mounting plate 12. By removing the mounting plate 12, the condenser 10 and the blower fan 3 can be separately inspected to maintain good heat dissipation performance. Specifically, two blower fans 3 are provided, and the two blower fans 3 correspond to the two third ventilation holes on the mounting plate 12 and are fixed to the outside of the mounting plate 12.

[0038] refer to Figure 4 As shown, the water-cooled unit also includes a filter 5, which is located between the condenser 10 and the mounting plate 12 and covers the second ventilation holes to reduce the possibility of dirt on the blower fan 3 being thrown onto the condenser 10. Specifically, a mounting cavity is formed between the condenser 10 and the mounting plate 12, and the filter 5 is fixed in the mounting cavity formed between the mounting plate 12 and the condenser 10 by plugging. By replacing the filter 5, the frequency of cleaning the blower fan 3 can be reduced. More specifically, the filter 5 includes a filter body and a mounting frame, wherein the filter body is fixed by the mounting frame. The mounting frame is configured in a rectangular shape and can simultaneously cover the two second ventilation holes to reduce the difficulty of disassembling and assembling the filter 5.

[0039] Optionally, the cooling module further includes an air suction fan 4. A third ventilation hole is provided on the side opposite the second ventilation hole of the housing 1. The air suction fan 4 is mounted on the side of the housing 1 directly opposite the third ventilation hole to cover the third ventilation hole. The addition of the air suction fan 4 increases the air pressure, increases the amount of cold air within the chamber, and further improves the efficiency of the water-cooling unit.

[0040] refer to Figure 5 and Figure 6 As shown, the housing 1 is also provided with an opening 13 for the refrigerant interface of the evaporator to pass through, thereby supplying refrigerant to the water-cooled unit. It is understood that the refrigerant in the evaporator can also be discharged through the refrigerant interface without disassembling the housing 1, which reduces the difficulty of cleaning and maintaining the water-cooled unit.
