Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for outdoor units of central air conditioning systems, specifically to the heat dissipation structure of outdoor units of central air conditioning systems. Background Technology

[0002] A central air conditioning system consists of one or more cold / heat source systems and multiple air conditioning systems. Unlike traditional refrigerant-based air conditioners, this system centrally processes air to achieve comfort requirements. It uses the principle of liquid vaporization refrigeration to provide the necessary cooling capacity to offset the cooling load of the indoor environment. The heating system provides the necessary heat to offset the heat load of the indoor environment. During the operation of the outdoor unit, a large amount of heat is generated, which needs to be dissipated to prevent excessively high temperatures from affecting the outdoor unit.

[0003] For example, application number 202322287812.6 describes a heat dissipation structure for a central air conditioning outdoor unit. This structure combines an exhaust fan, a guide shroud, a first heat sink, a diversion bracket, and a second heat sink. When the exhaust fan draws hot air from the outdoor unit, the air spirals into the guide shroud and contacts the first and second heat sinks. The guide shroud, with its outward-expanding tubular structure, accelerates the outward diffusion of air. The first and second heat sinks effectively reduce the temperature of the flowing air, driving the circulating air to rapidly lower the internal temperature of the unit. The second and first heat sinks fully contact the air diverted to the inner side of their interlayer structure, improving the efficiency of heat dissipation.

[0004] It has the following disadvantages: Although the guide shroud can accelerate the outward diffusion of air through its outward-expanding tubular structure, if the air passes through the guide shroud too quickly, the heat sinks (heat sink 1 and 2) may not be able to cool the air in time. This will reduce the effectiveness of the device in cooling the hot air extracted from the outdoor unit of the central air conditioner.

[0005] Therefore, we proposed a central air conditioning outdoor unit heat dissipation structure to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a heat dissipation structure for the outdoor unit of a central air conditioning system, thus solving the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution: A central air conditioning outdoor unit heat dissipation structure includes a heat dissipation housing. A first mounting bracket is fixedly installed inside the heat dissipation housing, and an exhaust fan is fixedly installed on the first mounting bracket. Heat dissipation components and dustproof components are respectively installed at both ends of the heat dissipation housing. The heat dissipation components are used to dissipate heat from the air drawn by the central air conditioning outdoor unit, and extend the air transport distance within the heat dissipation components to improve the heat dissipation effect of the air drawn by the central air conditioning outdoor unit. The dustproof components are used to filter dust from the air drawn by the central air conditioning outdoor unit, and the dustproof components are automatically cleanable.

[0008] Furthermore, the heat dissipation assembly includes a fixed frame fixedly mounted on the heat dissipation housing. The fixed frame contains a second mounting frame, a flow guide cylinder, and a flow guide column. The second mounting frame and the flow guide cylinder are fixedly connected to the fixed frame. The flow guide column is located inside the flow guide cylinder and is fixedly connected to the second mounting frame. The cross-sections of the flow guide cylinder and the flow guide column are wavy, and the wavy cross-sections of the flow guide cylinder and the flow guide column are parallel to each other.

[0009] Furthermore, multiple heat dissipation fins are fixedly installed on the side wall of the guide tube opposite to the guide column, a first water cavity is opened in the guide tube, and a second water cavity is opened in the guide column.

[0010] Furthermore, two water inlet pipes are fixedly installed on the lower end face of the fixing frame, and the two water inlet pipes are respectively connected to the first water cavity and the second water cavity. Two water outlet pipes are fixedly installed on the upper end face of the fixing frame, and the two water outlet pipes are respectively connected to the first water cavity and the second water cavity.

[0011] Furthermore, the dustproof component includes a dustproof net, on which an mounting plate is fixedly disposed, and the mounting plate is fixedly connected to the heat sink housing by bolts.

[0012] Furthermore, a transmission component is rotatably provided on the dustproof net, the position of the transmission component corresponds to that of the exhaust fan, and the transmission component is connected to the exhaust fan through a transmission shaft.

[0013] Furthermore, a cleaning strip is fixedly provided on the transmission component, the cleaning strip is attached to the dustproof net, and the cleaning strip is made of rubber.

[0014] Compared with the prior art, this utility model provides a heat dissipation structure for the outdoor unit of a central air conditioning system, which has the following beneficial effects: This invention utilizes a wave-shaped cross-section guide tube and guide column to extend the time air spends passing between them. This effectively increases the efficiency of heat dissipation by the heat sinks on the guide tube and guide column, thereby improving the heat dissipation effect of the device on the outdoor unit of the central air conditioner. Furthermore, the design of the first water chamber, second water chamber, outlet pipe, and inlet pipe enhances the heat dissipation effect of the heat sinks through physical water cooling. This prevents the heat sinks from reducing their heat dissipation effect due to high ambient temperatures, which would otherwise affect the device's heat dissipation effect on the outdoor unit of the central air conditioner.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] like Figure 1-7As shown in the figure, a central air conditioning outdoor unit heat dissipation structure proposed in one embodiment of the present invention includes a heat dissipation housing 1, a first mounting bracket 2 fixedly disposed inside the heat dissipation housing 1, an exhaust fan 3 fixedly disposed on the first mounting bracket 2, and heat dissipation components 4 and dustproof components 5 respectively disposed at both ends of the heat dissipation housing 1. The heat dissipation components 4 are used to dissipate heat from the air drawn by the central air conditioning outdoor unit, and the air drawn by the central air conditioning outdoor unit is extended in the heat dissipation components 4 to improve the heat dissipation effect of the air drawn by the central air conditioning outdoor unit. The dustproof components 5 are used to filter dust from the air drawn by the central air conditioning outdoor unit, and the dustproof components 5 are automatically cleanable.

[0019] like Figure 4 - Figure 7 As shown, the heat dissipation assembly 4 includes a mounting bracket 41 fixedly mounted on the heat dissipation housing 1. The mounting bracket 41 houses a second mounting bracket 42, a guide cylinder 43, and a guide column 44. The second mounting bracket 42 and the guide cylinder 43 are fixedly connected to the mounting bracket 41. The guide column 44 is located inside the guide cylinder 43 and is fixedly connected to the second mounting bracket 42. The cross-sections of the guide cylinder 43 and the guide column 44 are wavy, and their wavy cross-sections are parallel to each other. Multiple heat dissipation fins 45 are fixedly mounted on the opposite side wall of the guide cylinder 43 and the guide column 44. A first water cavity 48 is formed inside the guide cylinder 43, and a second water cavity 49 is formed inside the guide column 44. Two water inlet pipes 46 are fixedly installed on the lower end face of the fixing frame 41. The two water inlet pipes 46 are respectively connected to the first water chamber 48 and the second water chamber 49. Two water outlet pipes 47 are fixedly installed on the upper end face of the fixing frame 41. The two water outlet pipes 47 are respectively connected to the first water chamber 48 and the second water chamber 49.

[0020] The wave-shaped cross-section of the guide tube 43 and guide column 44 extends the time it takes for air to pass through them, effectively increasing the efficiency of heat dissipation by the heat sinks 45 on the guide tube 43 and guide column 44. This improves the heat dissipation effect of the device on the outdoor unit of the central air conditioner. The arrangement of the first water chamber 48, the second water chamber 49, the outlet pipe 47, and the inlet pipe 46 enhances the heat dissipation effect of the heat sink 45 through physical water cooling, preventing the heat sink 45 from reducing its heat dissipation effect due to high ambient temperature, which would otherwise affect the heat dissipation effect of the device on the outdoor unit of the central air conditioner.

[0021] like Figure 3As shown, the dustproof component 5 includes a dustproof mesh 51, on which a mounting plate 52 is fixedly mounted. The mounting plate 52 is fixedly connected to the heat sink housing 1 by bolts 53. A transmission component 54 is rotatably mounted on the dustproof mesh 51. The transmission component 54 corresponds to the position of the exhaust fan 3, and the transmission component 54 is connected to the exhaust fan 3 via a transmission shaft. A cleaning strip 55 is fixedly mounted on the transmission component 54 and is attached to the dustproof mesh 51. The cleaning strip 55 is made of rubber.

[0022] The dust filter 51 filters the air entering the heat sink housing 1, thus improving air quality. The transmission component 54 and the cleaning strip 55 clean the dust adhering to the dust filter 51 to the surrounding area, thus preventing the ventilation dust filter 51 from being blocked by dust.

[0023] The working principle of this practical application is as follows: When the exhaust fan 3 is started, it draws hot air from the outdoor unit of the central air conditioner to the space between the guide tube 43 and the guide column 44. As the drawn hot air passes through this space, the heat sinks 45 on the guide tube 43 and the guide column 44 cool it. The wavy cross-section of the guide tube 43 and the guide column 44 prolongs the time it takes for the hot air to pass through this space, effectively improving the efficiency of the heat sinks 45 in cooling the hot air passing through this space. During startup, the exhaust fan 3 drives the cleaning strip 55 to rotate via the drive shaft. The rotation of the cleaning strip 55 cleans the dust adhering to the dust filter 51, moving it to the periphery of the dust filter 51, thus preventing dust from being trapped by ventilation. The phenomenon of dust clogging at point 51; if the outdoor unit of the central air conditioner is in a high working environment, cold water is delivered through the inlet pipe 46 to the first water chamber 48 in the guide cylinder 43 and the second water chamber 49 in the guide column 44. The cold water in the first water chamber 48 and the second water chamber 49 can assist the heat dissipation of the heat sink 45 on the guide cylinder 43 and the guide column 44. The water used by the cold water in the first water chamber 48 and the second water chamber 49 to dissipate heat from the heat sink 45 on the guide cylinder 43 and the guide column 44 will be discharged through the outlet pipe 47. The arrangement of the first water chamber 48, the second water chamber 49, the outlet pipe 47, and the inlet pipe 46 can improve the heat dissipation effect of the heat sink 45 itself through physical water cooling. This can avoid the heat dissipation effect of the heat sink 45 itself being reduced due to the high ambient temperature, thus affecting the heat dissipation effect of the device on the outdoor unit of the central air conditioner.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
