The water evaporation carrier is located inside the air inlet of the housing and is supplied with water by the water tank and the water pump assembly. Its operating principle is that the fan assembly drives air through the water evaporation carrier, causing the water to vaporize at room temperature. The evaporated water absorbs the heat of vaporization, cooling and humidifying the water itself and the surrounding air. However, the cabinet structure of conventional water-cooled air conditioners generally adopts a single-channel, parallel inlet and outlet air flow structure. This heat dissipation air path has a limited cooling effect on the water tank, which can easily affect the cooling range of the air conditioner and increase its energy consumption during use. Utility Model Content

[0003] The main purpose of the utility model is to propose an air conditioning cabinet heat dissipation structure and air conditioner, aiming to solve the problem that the existing water-cooled air conditioning cabinet structure generally adopts a single-channel flat inlet and outlet air structure. This heat dissipation air path has a limited cooling effect on the water tank, which easily affects the cooling range of the air conditioner and increases its energy consumption during use.

[0004] To achieve the above-mentioned purpose, the present invention provides an air conditioning cabinet heat dissipation structure and an air conditioner, comprising:

[0006] An air guide device is installed on the end cover, and is used to cause the air in the enclosing shell to be discharged above the end cover to form a heat dissipation air path with air horizontally entering from the three ventilation surfaces and exhausting air upward from the end cover.

[0007] In one embodiment, the air conditioning cabinet heat dissipation structure and the air conditioner further include a heat dissipation water tank structure, and the heat dissipation water tank structure is provided corresponding to the three ventilation surfaces to achieve water cooling through the heat dissipation air path.

[0008] In one embodiment, the water tank structure includes three heat dissipation water tanks, which are respectively arranged corresponding to the three ventilation surfaces.

[0034] The cabinet structure of a conventional water-cooled air conditioner generally includes a housing 1, a fan assembly, a water tank, a water pump assembly, and a water evaporation carrier. The water evaporation carrier is disposed inside the air inlet of the housing 1, and is supplied with water by the water tank and the water pump assembly. Its operating principle is that the fan assembly drives air through the water evaporation carrier, causing the water to vaporize at room temperature. The evaporated water absorbs the heat of vaporization, thereby cooling and humidifying the water itself and the ambient air. However, the cabinet structure of conventional water-cooled air conditioners generally adopts a single-channel, parallel inlet and outlet air structure. This heat dissipation air path has a limited cooling effect on the water tank, which can easily affect the cooling range of the air conditioner and increase its energy consumption during use.

[0035] This utility model proposes an air conditioning cabinet heat dissipation structure to solve the above problems, please refer to Figures 1 to 5 .

[0036] An air conditioning cabinet heat dissipation structure 100, please refer to Figures 1 to 2 In one embodiment of the present invention, considering that the heat dissipation of the water tank in traditional air conditioning cabinet structures is mostly a one-way air inlet structure, generally speaking, the configuration of the cabinet housing 1, especially some liquid-cooled air conditioning structures, generally has the air inlet and air outlet arranged horizontally. Specifically, the water tank is mounted on the air inlet end surface, and a fan structure is also provided on the air inlet end surface to draw outside air in from the horizontal air inlet end and out from the other horizontal end. During this process, the airflow removes the heat from the water tank, thereby achieving the purpose of cooling the water in the water tank. In actual application, we will find that the above-mentioned traditional heat dissipation structure does not dissipate heat from the water tank significantly. Therefore, under normal circumstances, after the relevant heat dissipation structure has been in operation for a period of time, it is necessary to use the corresponding refrigeration structure (including the compressor structure) to assist in cooling the water in the water tank. The power of the compressor is relatively high when in operation, so this traditional air-cooling structure cannot effectively delay the start-up time of the compressor in actual use, and is not conducive to energy conservation. In this embodiment, the main purpose is to enhance the ventilation and heat dissipation of the entire cabinet through the design of the cabinet structure. Specifically, after the entire cabinet is installed through the mounting surface 2, it can be found that in this embodiment, the traditional front-facing air intake structure is replaced with a three-ventilation surface 3 air intake structure, and the air guide device is installed on the end cover 12 to form a heat dissipation air path with air intake horizontally from the three ventilation surfaces 3 and air exhaust upward from the end cover 12. This heat dissipation air path not only increases the air intake area, which is conducive to enhancing the air circulation effect within the enclosing shell 11, but also discharges the hot air directly upward based on the principle of hot air rising, which is conducive to the exhaust of hot air and can achieve better heat dissipation and ventilation effects.

[0037] Specifically, in this embodiment, a conventional heat dissipation water tank 4 is configured as three heat dissipation water tanks 4 corresponding to the three ventilation surfaces 3. Specifically, the heat dissipation water tanks 4 are fixedly mounted between the corresponding ventilation surfaces 3 and arranged in parallel, and the three heat dissipation water tanks 4 are interconnected. First, the multiple heat dissipation water tanks 4 can increase the amount of heat dissipation water during the air-cooling heat dissipation process, thereby achieving a better heat dissipation effect on the water. In addition, each heat dissipation water tank 4 is arranged corresponding to a ventilation surface 3, which can fully utilize the airflow at the ventilation surface 3. The multiple heat dissipation water tanks 4 are interconnected, and the temperature of the multiple heat dissipation water tanks 4 is cooled simultaneously, thereby effectively improving the heat dissipation effect on the water in the heat dissipation water tanks 4 and effectively increasing the cooling range of the water-cooled air conditioner. In specific usage scenarios, the relevant structure of this embodiment can achieve a better cooling effect on the heat dissipation water tanks 4. Therefore, the refrigeration system does not need to enter the operating state in advance. Within a certain temperature range, the cooling effect of the heat dissipation water tank 4 can be achieved through the above structure, avoiding the frequent operation of the refrigeration system and achieving energy efficiency to a certain extent.

[0038] Specifically, such as Figure 3 As shown, the three heat dissipation water tanks 4 are interconnected, achieving a parallel conduction effect. Each heat dissipation water tank 4 is provided with an inlet pipe 41 and an outlet pipe 42. One end of the pump body 51 is connected to an external water tank (not shown). A three-way valve is provided at the end of the main outlet pipe 52 at the output end of the pump body 51. One end of the three-way valve is directly connected to one of the inlet pipes 41. The other end of the three-way valve is connected to another three-way valve via an intermediate pipe, and then forms a connection relationship with the other two inlet pipes 41. The return water pipeline is also similar, with two outlet pipes 42 connected to one three-way valve, and then a section of conduit is connected to one end of the three-way valve, which is then connected to another outlet pipe 42. Finally, one end of the three-way valve is connected to the external water tank via the main inlet pipe 53. When the water pump is operating, the water in the external water tank is simultaneously introduced into the three radiator water tanks 4. The air guide device allows external air to enter the enclosing shell 11 from the three ventilation surfaces 3 at the same time, thereby effectively removing heat from the multiple flat tubes of the radiator water tanks 4 through the airflow. At the same time, the hot air is quickly discharged upward, greatly increasing the cooling effect on the radiator water tanks 4. It is conceivable that if the above structure of this solution is used in a car air conditioner, then the external water tank will become the radiator water tank structure of the car itself. In particular, when the external temperature is high, the above structure can also achieve efficient heat dissipation, thereby delaying the working time of the refrigeration structure and achieving energy saving effect.

[0039] In this embodiment, the conductive structure on the ventilation surface 3 is set as a plurality of ventilation holes 6, such as Figure 1As shown, air enters the interior through a plurality of ventilation holes 6. The size of the ventilation holes 6 can be set according to actual conditions, and is generally 100mm-200mm long and 60mm-120mm wide. The ventilation holes 6 do not affect the air intake effect, and can also relatively isolate the internal and external environments and protect the internal structure.

[0040] The air guide device is configured as two fans 13. Specifically, two mounting holes 14 are provided on the end cover 12, each for mounting the two fans 13. A protective mesh structure is also provided on the side of the mounting holes 14 corresponding to the exterior. The two fans 13 operate simultaneously, directing relatively cool outside air into the enclosing housing 11 through the multiple ventilation surfaces 3. The air, which has absorbed heat from the heat dissipation tank 4 and has risen in temperature, is directed upward through the end cover 12 by the fans 13 for discharge.

[0041] Specifically, a corresponding electrical control device 71 is also provided within the enclosure 11, capable of monitoring related components, ambient temperature, and water temperature. To mount the electrical control device 71 and simultaneously enhance the overall strength of the enclosure 11, a support bracket 7 is provided within the enclosure 11 corresponding to the mounting surface 2, upon which the electrical control device 71 is mounted. It is also conceivable that multiple mounting brackets may be provided, each mounted on the bottom of the enclosure 11 and the end cap 12, thereby enhancing the overall support strength of the enclosure 1.

[0042] To facilitate maintenance of the electrical control device 71 inside the housing 1, the end cover 12 is configured in two parts in this embodiment. The second cover 122 has a narrower overall width and is installed directly above the electrical control device 71. During actual maintenance, the electrical control device 71 can be replaced and maintained by directly removing the second cover 122 without removing the first cover 121. This avoids the need to directly remove the entire end cover 12, making maintenance more convenient.

[0043] like Figure 3 and Figure 4 As shown, in order to maintain a relatively stable fixed relationship between the heat dissipation water tank 4 and the corresponding ventilation surface 3, a plurality of fixing ears 8 are provided on each heat dissipation water tank 4. When the heat dissipation water tank 4 is installed, the fixing ears 8 can be fixed to the ventilation surface 3 by bolts, thereby ensuring the stable installation state of the heat dissipation water tank 4.

[0044] The present invention also proposes an air conditioner, which includes the above-mentioned air conditioning cabinet heat dissipation structure 100. The specific structure of the air conditioning cabinet heat dissipation structure 100 refers to the above-mentioned embodiment. Since the air conditioning cabinet heat dissipation structure 100 of this air conditioner adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0045] The air conditioner includes an air conditioning cabinet heat dissipation structure 100 and a refrigeration structure. The refrigeration structure is a conventional structure in traditional air conditioners. During installation, the compressor condenser 9 is installed on one of the heat dissipation water tanks 4 corresponding to the side of the covering shell 11. The compressor (not shown in the figure) is connected to the compressor condenser 9 and the connecting pipe, which can assist the pipe in cooling. In addition to the above structure, the traditional refrigeration structure also includes: an expansion valve, a plate heat exchanger, and a conducting pipe. The expansion valve, the plate heat exchanger, and the compressor condenser 9 are all arranged on one of the heat dissipation water tanks 4 corresponding to the side of the covering shell 11. The compressor, the compressor condenser 9, the expansion valve, and the plate heat exchanger form a connection loop through the conducting pipe to form a complete refrigeration system. Since the above refrigeration structure is a publicly known structure, it will not be described in detail here.

[0046] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
