Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat dissipation technology for air conditioning equipment, specifically, to a radiator for air conditioning. Background Technology
[0002] In an air conditioning system, the radiator is a core component for balancing the heat load of the equipment, and its performance directly determines the stability, cooling efficiency, and lifespan of the air conditioner. When the air conditioner is working, key components such as the compressor, refrigeration equipment, and circuit boards continuously generate a large amount of heat. With the increased integration of chips on modern circuit boards, if the heat cannot be dissipated in time, it may lead to a decrease in the air conditioner's energy efficiency ratio, or trigger malfunctions such as component overheating protection or circuit burnout.
[0003] According to a disclosed radiator for air conditioning (publication number: CN221259090U), it includes: a base; a heat dissipation box fixedly connected to the top right side of the base; a water storage tank fixedly connected to the left side of the heat dissipation box; a first fan fixedly connected to the top left front side of the base; a first suction pipe fixedly connected to the input end of the first fan; a first air delivery pipe fixedly connected to the output end of the first fan; and a second fan fixedly connected to the top left side of the base; a second suction pipe fixedly connected to the input end of the second fan; and a second air delivery pipe fixedly connected to the output end of the second fan. In this utility model, through the cooperation of the heat dissipation box, water storage tank, first fan, first suction pipe, first air delivery pipe, second fan, second suction pipe, and second air delivery pipe, the radiator for air conditioning can efficiently cool the air conditioner body, preventing the air conditioner from overheating and affecting the cooling effect.
[0004] The aforementioned application achieved basic heat dissipation for air conditioners through the coordinated design of the fan and water tank. However, it lacked specific heat dissipation design and did not design a dedicated heat dissipation structure for precision components such as circuit boards, resulting in low heat dissipation efficiency for heat sources such as chips. Therefore, we propose a heat sink for air conditioners. Utility Model Content
[0005] To overcome the above-mentioned defects, this utility model provides a radiator for air conditioners, which solves the problems of insufficient heat dissipation for precision components, cumbersome cleaning of air intake filters, and the existence of heat dissipation dead zones in the prior art.
[0006] According to one aspect, at least one embodiment of the present invention provides a radiator for an air conditioner, comprising: a housing, a handle provided on the side of the housing, an air outlet hood fixedly connected to the side of the housing, an air inlet filter fixedly connected to the side of the housing, a fan rotatably connected to the side of the inner wall of the housing, fins fixedly connected to the bottom of the inner wall of the housing, a partition fixedly connected to the bottom of the inner wall of the housing, a refrigeration device fixedly connected to the bottom of the inner wall of the housing, a circuit board fixedly connected to the side of the housing, and a heat dissipation device provided on the top of the circuit board; The heat dissipation device includes a heat-conducting plate, the bottom of which is fixedly connected to the top of a circuit board. A water collection tank is fixedly connected to the top of the circuit board. A water inlet pipe is fixedly connected to the side of the water collection tank, and a drain pipe is fixedly connected to the side of the water collection tank. Heat dissipation fins are fixedly connected to the bottom of the inner wall of the water collection tank. An air guide box is fixedly connected to the side of the partition, and the side of the air guide box is fixedly connected to the inner wall of the box. An air inlet slot is provided on the side of the partition, and an air outlet slot is provided on the side of the box.
[0007] For example, in at least one embodiment of this utility model, an air conditioner radiator further includes: a support base fixedly connected to the bottom of the circuit board; the side of the support base fixedly connected to the inner wall side of the housing; one end of the water inlet pipe passing through the side of the housing; and one end of the drain pipe passing through the side of the housing. The support base fixes the circuit board, reducing the risk of solder joint cracking caused by vibration during fan operation; the through holes enhance the sealing of the pipes, preventing condensate from seeping into the circuit area and causing a short circuit.
[0008] The bottom of the heat-conducting plate has a chip heat-conducting groove, and the top of the heat-conducting plate is fixedly connected to a heat-conducting protrusion, the top of which penetrates the bottom of the inner wall of the water collection tank. The chip heat-conducting groove is in close contact with the heat source, improving heat conduction efficiency. Heat is directly introduced into the condensate through the protrusion, and through air convection on the water collection tank wall, it helps to cool the motherboard temperature.
[0009] The portion of the heat-conducting protrusion that penetrates the bottom of the inner wall of the water collection tank is covered with sealant, and several heat-conducting protrusions are provided. The sealant fills the contact gaps between the tank body and extends the service life of the device.
[0010] The system includes multiple air inlet and outlet slots. The air inlet slots are arranged in a linear array on the side of the partition, and the air outlet slots are arranged in a linear array on the side of the housing. This array-type air slot design improves the uniformity of airflow distribution and eliminates heat dissipation dead zones.
[0011] According to another aspect, at least one embodiment of the present invention also provides an air conditioner radiator, comprising: a cleaning device, the cleaning device including a motor housing, the side of the motor housing being fixedly connected to the side of a housing body, a drive motor being fixedly connected to the bottom of the inner wall of the motor housing, a threaded rod being fixedly connected to the output end of the drive motor, a threaded sleeve being threadedly connected to the circumferential surface of the threaded rod, a transmission rod being fixedly connected to the circumferential surface of the threaded sleeve, and a cleaning brush being fixedly connected to one end of the transmission rod.
[0012] For example, in at least one embodiment of this utility model, an air conditioner radiator further includes: the side of the cleaning brush contacts the side of the air inlet filter, and the displacement trajectory of the cleaning brush is equal to the diameter of the air inlet filter. The cleaning brush completely covers the surface of the air inlet filter, removing accumulated dust without dead corners, extending the automatic cleaning cycle of the air inlet filter, and reducing the frequency of disassembly.
[0013] A limiting groove is provided on the side of the motor housing, and the side of the transmission rod is slidably connected inside the limiting groove. The limiting groove guides the transmission, restricts the displacement of the transmission rod, and prevents jamming.
[0014] The cleaning brush has a guide groove fixedly connected to its side, and a guide plate is slidably connected to the inner wall of the guide groove. The guide groove and the guide plate are linked, and the vertical slide rail ensures that the cleaning brush is always in close contact with the air inlet filter.
[0015] A positioning block is fixedly connected to the side of the guide plate, and the side of the positioning block is fixedly connected to the side of the housing. Two positioning blocks are provided. The double positioning blocks can distribute stress and enhance the overall rigidity.
[0016] The beneficial effects of the embodiments of this utility model are as follows: 1. In this utility model, the heat dissipation device uses the heat-conducting grooves of the heat-conducting plate to adhere to the heat source. Heat is transferred to the water collection tank via the heat-conducting protrusions, where it exchanges heat with the water flow in conjunction with the heat dissipation fins. Simultaneously, the air guide box guides airflow through the air inlet and outlet slots to form convection, achieving efficient and coordinated cooling of the circuit board. This solves the problems of dead zones and low efficiency in traditional heat dissipation. The support base fixes the circuit board to reduce the impact of vibration, and the sealant prevents condensate leakage, improving the stability and safety of equipment operation and extending its service life.
[0017] 2. In this utility model, the cleaning device uses a drive motor to move the cleaning brush along the air inlet filter by driving a threaded rod. Combined with the guiding effect of the limiting groove and the guide plate, it ensures that the cleaning brush completely covers the surface of the air inlet filter, automatically removing accumulated dust. This solves the problems of tedious manual cleaning and easy clogging of the air inlet filter. The double positioning blocks enhance structural rigidity, reduce operational failures, lower maintenance frequency, ensure smooth air intake, and indirectly improve heat dissipation efficiency. It is suitable for air conditioning heat dissipation scenarios requiring long-term stable operation. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.
[0022] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

Therefore, they should not be construed as limitations on this utility model.
[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0027] like Figures 1-5 The illustration shows an embodiment of an air conditioner radiator, comprising: a housing 1, a handle 2 on the side of the housing 1, an air outlet cover 3 fixedly connected to the side of the housing 1, an air inlet filter 4 fixedly connected to the side of the housing 1, a fan 5 rotatably connected to the inner wall side of the housing 1, fins 6 fixedly connected to the bottom of the inner wall of the housing 1, a partition 7 fixedly connected to the bottom of the inner wall of the housing 1, a refrigeration device 8 fixedly connected to the bottom of the inner wall of the housing 1, a circuit board 9 fixedly connected to the side of the housing 1, and a heat dissipation device 10 provided on the top of the circuit board 9. The heat dissipation device 10 includes a heat-conducting plate 1001, the bottom of which is fixedly connected to the top of the circuit board 9. A water collection tank 1002 is fixedly connected to the top of the circuit board 9. A water inlet pipe 1003 is fixedly connected to the side of the water collection tank 1002. A drain pipe 1004 is fixedly connected to the side of the water collection tank 1002. Heat dissipation fins 1005 are fixedly connected to the bottom of the inner wall of the water collection tank 1002. An air guide box 1006 is fixedly connected to the side of the partition 7. The side of the air guide box 1006 is fixedly connected to the side of the inner wall of the box 1. An air inlet slot 1007 is provided on the side of the partition 7. An air outlet slot 1008 is provided on the side of the box 1.
[0028] In some examples, a support base is fixedly connected to the bottom of the circuit board 9, and the side of the support base is fixedly connected to the inner wall of the housing 1. One end of the water inlet pipe 1003 passes through the side of the housing 1, and one end of the drain pipe 1004 passes through the side of the housing 1. The support base fixes the circuit board 9, reducing the risk of solder joint cracking caused by vibration during fan operation. The through holes enhance the sealing of the pipes and prevent condensate from seeping into the circuit area and causing a short circuit.
[0029] The bottom of the heat-conducting plate 1001 has a chip heat-conducting groove, and the top of the heat-conducting plate 1001 is fixedly connected to a heat-conducting protrusion 1009, the top of which penetrates the bottom of the inner wall of the water collection tank 1002. The chip heat-conducting groove is in close contact with the heat source, improving heat conduction efficiency. Heat is directly transferred to the condensate through the protrusion, and air convection through the wall of the water collection tank 1002 helps to cool the motherboard temperature.
[0030] The portion of the heat-conducting protrusion 1009 penetrating the bottom of the inner wall of the water collection tank 1002 is covered with sealant, and several heat-conducting protrusions 1009 are provided. The sealant fills the contact gaps of the tank body 1, extending the service life of the device.
[0031] There are several air inlet slots 1007 and several air outlet slots 1008. The air inlet slots 1007 are arranged in a linear array on the side of the partition 7, and the air outlet slots 1008 are arranged in a linear array on the side of the housing 1. The array-type air slots improve the uniformity of airflow distribution and eliminate heat dissipation dead zones.
[0032] For example, such as Figures 1-5In the air conditioning operation, the heat generated by the circuit board 9 is quickly conducted to the heat-conducting protrusion 1009 at the top through the chip heat-conducting groove at the bottom of the heat-conducting plate 1001. The heat is then transferred to the condensate in the water collection tank 1002 through the heat-conducting protrusion 1009. The heat dissipation fins 1005 on the inner wall of the water collection tank 1002 expand the heat dissipation area and accelerate heat exchange. At the same time, the fan 5 drives the airflow through the air inlet filter 4 into the housing 1, and guides it to the air inlet slot 1007 of the partition 7 through the air guide box 1006. After flowing through the fins 6 and cooling down, the air carrying heat is discharged from the air outlet slot 1008 and the air outlet cover 3 of the housing 1, forming a coordinated heat dissipation system of heat conduction, water cooling and air cooling. The support base fixes the circuit board 9 to reduce vibration interference, and the sealant prevents condensate leakage and ensures stable heat dissipation.
[0033] like Figures 1-5 This illustration shows an air conditioner radiator according to another embodiment of the present invention, comprising: a cleaning device 11, the cleaning device 11 including a motor housing 1101, the side of the motor housing 1101 being fixedly connected to the side of the housing 1, a drive motor 1102 being fixedly connected to the bottom of the inner wall of the motor housing 1101, a threaded rod 1103 being fixedly connected to the output end of the drive motor 1102, a threaded sleeve 1104 being threadedly connected to the circumferential surface of the threaded rod 1103, a transmission rod 1105 being fixedly connected to the circumferential surface of the threaded sleeve 1104, and a cleaning brush 1106 being fixedly connected to one end of the transmission rod 1105.
[0034] In some examples, the side of the cleaning brush 1106 contacts the side of the air intake filter 4, and the displacement trajectory of the cleaning brush 1106 is equal to the diameter of the air intake filter 4. The cleaning brush 1106 completely covers the surface of the air intake filter 4, removing accumulated dust without dead corners, extending the automatic cleaning cycle of the air intake filter 4, and reducing the frequency of disassembly.
[0035] A limiting groove is provided on the side of the motor housing 1101, and the side of the transmission rod 1105 is slidably connected inside the limiting groove. The limiting groove guides the transmission, restricts the offset of the transmission rod 1105, and prevents jamming.
[0036] A guide groove 1107 is fixedly connected to the side of the cleaning brush 1106, and a guide plate 1108 is slidably connected to the inner wall of the guide groove 1107. The guide groove 1107 and the guide plate 1108 are linked, and the vertical slide rail ensures that the cleaning brush 1106 is always in close contact with the air inlet filter 4.
[0037] A positioning block is fixedly connected to the side of the guide plate 1108. The side of the positioning block is fixedly connected to the side of the housing 1, and two positioning blocks are provided. The double positioning blocks can distribute stress and enhance the overall rigidity.
[0038] For example, such as Figures 1-5When dust accumulates on the air inlet filter 4, the operator starts the drive motor 1102 in the cleaning device 11. The drive motor 1102 drives the threaded rod 1103 to rotate, causing the threaded sleeve 1104 to drive the transmission rod 1105 to slide along the limiting groove of the motor box 1101. The cleaning brush 1106 at one end of the transmission rod 1105 moves close to the surface of the air inlet filter 4 under the constraint of the guide groove 1107 and the guide plate 1108. Its displacement trajectory covers the diameter of the filter screen, thoroughly removing the accumulated dust. The double positioning blocks enhance the rigidity of the guide plate 1108, preventing the parts from shifting during the cleaning process, ensuring that the air inlet filter 4 is unobstructed, and maintaining the efficiency of heat dissipation airflow.
[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
