They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0033] In order to more clearly describe the structure of the above-mentioned air-water cooler, the present invention defines the terms "distal end" and "proximal end". Specifically, the "distal end" refers to the end away from the plane where the air inlet 11 is located, and the "proximal end" refers to the end close to the plane where the air inlet 11 is located. Figure 1 For example, Figure 1 The end of the middle water inlet 38 close to the exhaust valve 35 is the far end. Figure 1 The end of the middle water inlet 38 close to the drain port 36 is the proximal end.

[0034] Please refer to Figure 1 , Figure 3 and Figure 4 An air-water cooler includes a heat exchange mechanism 3, a first air hood 1 and a second air hood 2, wherein the heat exchange mechanism 3 includes a plurality of horizontally arranged heat exchange plates 31, a channel 312 is provided in the heat exchange plates 31, and a heat exchange air duct 313 is formed between adjacent heat exchange plates 31. The first air hood 1 and the second air hood 2 are arranged on horizontally opposite sides of the heat exchange mechanism 3, a first air duct 14 is provided in the first air hood 1, and the first air duct 14 connects the proximal end of the first air hood 1 and the heat exchange air duct 313. A second air duct 24 is provided in the second air hood 2, and the second air duct 24 connects the proximal end of the second air hood 2 and the heat exchange air duct 313. Specifically, a plurality of support plates 34 are further provided at the proximal end of the heat exchange mechanism 3, the support plates 34 are bolted to the first air hood 1 and the second air hood 2, and the heat exchange mechanism 3 is installed at the distal end of the support plates 34. The support plates 34 fix the heat exchange mechanism 3 to enhance the stability of the heat exchange mechanism 3. The first wind hood 1 plays the role of buffering gas and controlling the flow direction of gas. The gas is buffered by the first wind hood 1, so that the flow of gas blown onto the heat exchange mechanism 3 is more stable, and the first wind hood 1 can also filter out some impurities and pollutants in the gas, reducing the pollution and damage of the gas to the heat exchange mechanism 3. In addition, the air inlet 11 of the first wind hood 1 and the air outlet 21 of the second wind hood 2 are arranged on the same side, and the gas pipeline is also arranged on the same side, which effectively simplifies the layout of the gas pipeline and facilitates installation and maintenance.

[0035] The specific structure of the fan 22 and the elastic pad 33 is described below:

[0036] Please refer to Figure 2 and Figure 3 A fan 22 is provided at one end of the second hood 2 away from the heat exchange mechanism 3. Specifically, the fan 22 may be a centrifugal fan 22, the suction end of the fan 22 is aligned with the heat exchange mechanism 3, and the blowing end of the fan 22 is toward the proximal end of the second hood 2. The fan 22 blows the gas along the air inlet 11, the first air duct 14, the heat exchange air duct 313, the second air duct 24 and the air outlet 21, so that the gas exchanges heat in the heat exchange air duct 313.

[0037] Please refer to Figure 3A bracket 23 is also provided between the fan 22 and the second wind hood 2. Specifically, the bracket 23 includes a bottom plate (marked in the figure) horizontally arranged at the proximal end of the fan 22, and two side plates (not marked in the figure) arranged at the distal end of the bottom plate, and the fan 22 is fixed between the two side plates. The bottom plate and the side plates are bolted to the outer surface of the second wind hood 2. The bottom plate and the side plates fix the fan 22, ensuring the stability of the operation of the fan 22, and also play a protective role to prevent foreign objects from hitting the fan 22.

[0038] Please refer to Figure 1 , elastic pads 33 are respectively provided between the heat exchange mechanism 3 and the first hood 1, and between the heat exchange mechanism 3 and the second hood 2. Specifically, the heat exchange mechanism 3 and the first hood 1, and between the heat exchange mechanism 3 and the second hood 2 are fixedly connected by bolts. When the heat exchange mechanism 3 is in operation, the liquid flows in the channel 312, which will cause the heat exchange mechanism 3 to vibrate. The flow of gas in the first hood 1 and the second hood 2 will also cause vibration and impact. The elastic pad 33 can effectively absorb and buffer the vibration, improve the stability of operation, and extend the service life of the equipment.

[0039] The specific structure of the fin 311 and the cover plate 32 is described below:

[0040] Please refer to Figure 4 and Figure 6 , fins 311 are also provided between adjacent heat exchange plates 31. Specifically, a plurality of fins 311 are provided between the heat exchange plates 31 along the direction of gas flow, and the same fin 311 simultaneously connects two heat exchange plates 31, and a plurality of fins 311 are parallel to each other. The provision of a plurality of fins 311 effectively increases the contact area, thereby increasing the heat transfer speed and improving the heat exchange efficiency. The presence of the fins 311 increases the turbulence of the airflow, thereby enhancing the convective heat transfer effect. The presence of the fins 311 makes the structure in the heat exchange air duct 313 more complex, thereby increasing the residence time of heat in the heat exchanger and increasing the heat exchange effect. In addition, the fins 311 also connect adjacent heat exchange plates 31, thereby enhancing the strength and service life of the heat exchange mechanism 3.

[0041] Please refer to Figure 6 The channel 312 is perpendicular to the connection direction of the first wind shield 1 and the second wind shield 2. Cover plates 32 are respectively provided at both ends of the channel 312. A cavity 321 is provided in the cover plate 32. The cavity 321 is connected to several channels 312 at the same time. Specifically, a water inlet 38 is provided on one cover plate 32, and a water outlet 39 is provided on the other cover plate 32. The cavity 321 that is connected to several channels 312 at the same time facilitates the replenishment of liquid to all channels 312 at the same time. Liquid can be replenished to several channels 312 at the same time by simply connecting the water inlet 38.

[0042] Please refer to Figure 1The far end of the cover plate 32 is provided with an exhaust valve 35, and the proximal end of the cover plate 32 is provided with a drain port 36. Specifically, when the liquid flows in the channel 312, a part of the air will be released. Excessive accumulation of air will cause air blockage, which will affect the heat exchange efficiency and even damage the heat exchange mechanism 3. The exhaust valve 35 can exhaust the air to prevent the occurrence of air blockage. The drain port 36 is connected to the proximal end of the cavity 321 in the cover plate 32. When the heat exchange mechanism 3 needs to be cleaned and maintained, the exhaust port 36 can be opened to drain the liquid in the heat exchange mechanism 3.

[0043] The specific structures of the line card 12, the first sensor, the second sensor and the heat exchange mechanism 3 are described below:

[0044] Please refer to Figure 1 , a plurality of wire clips 12 are arranged on the outer surfaces of the first hood 1 and the second hood 2. Specifically, the cables connecting the fan 22, the first sensor and the second sensor are arranged in the corrugated tube 13, and the corrugated tube 13 is fixed to the outer surfaces of the first hood 1 and the second hood 2 through the wire clips 12. The cables are fixed to the outer surfaces of the first hood 1 and the second hood 2, which is convenient for personnel to connect and install, and at the same time, the internal space of the first hood 1 and the second hood 2 is vacated for gas flow to ensure heat exchange efficiency.

[0045] Please refer to Figure 3 , a first sensor (not shown in the figure) is disposed at the proximal end of the first air duct 14 and the second air duct 24, and a second sensor (not shown in the figure) is disposed at both ends of the channel 312. Specifically, the first sensor may be a thermocouple temperature sensor, and the thermocouple is disposed in the first air duct 14 and the second air duct 24 to measure the temperature of the airflow in the first air duct 14 and the second air duct 24, and assist the operator in determining the working state. The second sensor may be a water temperature sensor, and the probe of the water temperature sensor extends into the cavity 321 of the cover plate 32 to detect the temperature of the liquid in the heat exchange mechanism 3 in real time, and assist the operator in determining the working state.

[0046] Please refer to Figure 1 The heat exchange mechanism 3, the first wind cover 1 and the second wind cover 2 are respectively provided with hoisting holes 37 at their far ends. Specifically, the hoisting holes 37 facilitate personnel or a hoisting device (not shown) to hoist the heat exchange mechanism 3, the first wind cover 1 and the second wind cover 2 to simplify installation.

[0047] The specific working process of the utility model is as follows:

[0048] When cooling is performed, the fan 22 is started, and the gas flows along the air inlet 11, the first air duct 14, the heat exchange air duct 313, the second air duct 24 and the air outlet 21. The liquid flows along the water inlet 38, the cavity 321, the channel 312, the cavity 321 and the water outlet 39. In this process, the first wind hood 1 buffers the gas and controls the gas to flow toward the heat exchange mechanism 3. When the gas flows through the heat exchange air duct 313, heat is exchanged with the liquid.

[0049] It can be seen that in the above-mentioned air-water cooler, the first wind hood 1 plays the role of buffering gas and controlling the flow direction of gas. The gas passes through the buffer of the first wind hood 1, so that the flow of gas blown onto the heat exchange mechanism 3 is more stable, and the first wind hood 1 can also filter out some impurities and pollutants in the gas, reducing the pollution and damage of the gas to the heat exchange mechanism 3. In addition, the air inlet 11 of the first wind hood 1 and the air outlet 21 of the second wind hood 2 are both arranged on the same side, and the gas pipeline is also arranged on the same side, which effectively simplifies the layout of the gas pipeline and facilitates installation and maintenance.

[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
