[0036] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0037] like Figure 1-4 As shown, a cooling device is installed on the conveyor line during use to cool down the sprayed workpiece after it has been heated and cured on the conveyor line.

[0038] The cooling device includes a housing 100 and a fan 310. The housing 100 is typically rectangular. The housing 100 has a cooling chamber 110, and the side wall of the housing 100 has an inlet 111 and an outlet 112, which are respectively connected to the cooling chamber 110, allowing the conveyor line to enter and exit.

[0039] In this embodiment, the housing 100 further includes a heat dissipation cavity 120. The cooling device also includes a heat exchanger disposed within the heat dissipation cavity 120, and a flow guiding assembly disposed within the cooling cavity. The heat exchanger is capable of absorbing heat from the air within the heat dissipation cavity 120, thereby cooling the hot air.

[0040] Two communication ports are provided between the heat dissipation cavity 120 and the cooling cavity 110. The fan 310 is disposed in one of the heat dissipation cavity 120 and the cooling cavity 110 to form a circulating airflow between the heat dissipation cavity 120 and the cooling cavity 110. The airflow guiding assembly is connected to at least one of the communication ports to guide the airflow along the extension direction of the conveyor line.

[0041] In some embodiments, the communication port between the heat dissipation cavity 120 and the cooling cavity 110 includes an air inlet and an air outlet 113. The air inlet and air outlet 113 are arranged on both sides along the length of the housing 100. This arrangement maximizes the use of the space in the housing 100.

[0042] For example, the fan 310 is located at the air inlet and is used to deliver airflow into the cooling chamber 110 through the air inlet.

[0043] For example, the feed inlet 111 and the air inlet are located on the same side of the housing 100. The air temperature entering the cooling chamber 110 from the air inlet is the lowest, and the surface temperature of the workpiece entering the cooling chamber 110 from the feed inlet 111 is the highest. Therefore, placing them close together allows the air with the lowest temperature to come into contact with the workpiece with the highest temperature first. Since the temperature difference between the two is the largest, the cooling effect on the workpiece is also the most obvious.

[0044] In some embodiments, the airflow guiding assembly includes an air intake pipe 114 communicating with the air inlet. The air intake pipe 114 extends from the air inlet to the air outlet 113 within the cooling chamber 110. The air intake pipe 114 has multiple air outlets, the opening direction of which is opposite to the conveyor line. The fan 310 is located within the heat dissipation chamber 120, avoiding encroachment on the internal space of the cooling chamber 110 and preventing interference with airflow within the cooling chamber 110.

[0045] For example, the air inlet pipe 114 is designed to be suspended above the cooling chamber 110, employing a flat structure with a width sufficient to cover the entire width of the conveyor line below, accommodating single or multiple conveyor lines arranged side-by-side. The main purpose of this design is to ensure uniform airflow distribution and delivery to multiple areas of the conveyor line, thereby improving the cooling efficiency of the coated workpiece.

[0046] For example, the air inlet pipe 114 extends in the same direction as the conveyor line, allowing the air entering the cooling chamber 110 to directly contact the workpiece to be cooled, forming a more direct heat exchange. The bottom of the air inlet pipe 114 is covered with air outlet holes to ensure that the air can be released evenly, enhancing the coverage and flow of the airflow.

[0047] For example, the air outlet is equipped with an airflow nozzle 115, which is directly aligned with the conveyor line. This design effectively improves the contact efficiency between air and the workpiece surface by concentrating the airflow and increasing its velocity, thereby accelerating the heat dissipation of the workpiece. The precise positioning of the airflow nozzle 115 helps optimize the directionality and intensity of the airflow, making the cooling process faster and more efficient.

[0048] Furthermore, the inlet 111 and outlet 112 are located on the same side along the length of the housing 100 and are positioned opposite each other in the width direction. This layout allows for the placement of a U-shaped conveyor line within the cooling chamber 110. Positioning the inlet 111 and outlet 112 on the same side reduces airflow interference within the cooling chamber 110, preventing airflow turbulence caused by multiple inlet and outlet points. This design maintains airflow stability, improves cooling efficiency, and ensures continuous cooling effectiveness.

[0049] In some embodiments, the cooling device further includes a plurality of filter assemblies 330 disposed in the heat dissipation cavity 120. The plurality of filter assemblies 330 are located between the air outlet 113 and the air inlet, and divide the heat dissipation cavity 120 into at least two sections. The main purpose of this design is to enhance the filtration and cooling effect of the air.

[0050] In some embodiments, the filter plate is vertically arranged, with its left and right sides connected and repeatedly folded into a W shape. Through this W-shaped folding, the filter assembly 330 can more efficiently capture fine particles in the air, reducing the release of pollutants and extending the lifespan of the device. The contact area of ​​the filter plate is significantly increased, thereby improving its contact area with the air. This enhanced contact area makes the filter more efficient at filtering dust and impurities from the air, effectively improving the overall cleaning performance of the system.

[0051] In some embodiments, the radiator includes an inlet pipe 321 and an outlet pipe, wherein the inlet pipe 321 is connected to the top of the filter assembly 330, and the outlet pipe is connected to the bottom of the heat dissipation cavity 120. This design achieves two functions: firstly, water, as a coolant, can directly participate in heat exchange, effectively reducing the air temperature; secondly, when water flows through the filter assembly 330, it can form a water film on its surface. This water film not only enhances the adsorption effect of dust, but can also be washed away after accumulating to a certain extent, thereby giving the filter a certain self-cleaning ability, reducing maintenance frequency, and thus reducing production costs.

[0052] By using water as the cooling medium, the design of the inlet pipe 321 and outlet pipe enables continuous heat exchange, ensuring that the temperature within the heat dissipation chamber 120 remains at an optimal level. This not only improves overall cooling efficiency but also allows for a faster cooling rate on the coated workpiece.

[0053] In some embodiments, the housing 100 is provided with a shelf 130, which separates the housing 100 into a hot chamber and a cooling chamber 110 between the top and bottom of the housing 100. The shelf 130 is inclined, and the water outlet pipe is located at the lower part of the shelf 130. The inclined arrangement of the shelf 130 allows water to flow to the water outlet pipe more quickly, avoiding water stagnation and thus improving the efficiency of the entire cooling process. By rationally combining the water flow and air flow paths, the temperature of the sprayed workpiece can be effectively reduced. Furthermore, because the water outlet pipe is located at a lower position, the water flow is smooth and less prone to clogging, reducing maintenance difficulty. In addition, the shelf 130 can collect excess moisture, thereby reducing the humidity inside the housing 100 and keeping the equipment dry.

[0054] In some embodiments, the top surface of the shelf 130 is provided with a water inlet channel 131, which is bent and extended, and the filter assembly 330 is mounted on the water inlet channel 131. The design of the water inlet channel 131 allows the cooling water to be effectively dispersed, avoiding the waste caused by the cooling water concentrating in one place. At the same time, the reasonable water flow distribution helps to improve water use efficiency and reduce resource waste.

[0055] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
