Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and more particularly to a radiator and an air conditioner. Background Art

[0002] With the continuous expansion of market demand, users need air conditioners with greater refrigeration capacity. To provide greater refrigeration capacity for the air conditioner, it is necessary to increase the input current of the compressor, making the operating frequency of the compressor higher. The greater the input current of the compressor, the greater the current carried by the compressor control module on the outdoor unit main board, resulting in excessive heat generation of the components (compressor control module), which will affect the service life of the compressor control module.

[0003] For heat-generating components with relatively large heat generation (compressor control module), considering the heat conduction ability of the heat-generating components themselves, the heat-generating components need to be encapsulated using an iron seal encapsulation method, and the electrical safety problems caused by the direct contact between the heat-generating components and the radiator need to be solved.

[0004] In the prior art, the refrigerant pipeline is used to introduce heat to the outdoor unit main board for heat dissipation. However, the contact efficiency between the heat-generating components on the outdoor unit main board and the refrigerant pipeline is low, and the heat dissipation and cooling effect are not as expected.

[0005] Moreover, the heat dissipation structure of the prior art will form a fixed cooperation structure with the outdoor unit main board and the heat dissipation cooperation structure of the heat-generating components. In order to achieve better contact, if there is a problem with the heat-generating components or maintenance is required, it is difficult to disassemble and the components are easily damaged.

[0006] In summary, the heat-generating components in the prior art have problems of poor heat dissipation and cooling effect and difficult disassembly. Summary of the Utility Model

[0009] Further, the heat-generating components have opposite first and second surfaces. The first surface of the heat-generating components faces the bottom of the placement groove, and the limiting pressing piece abuts against the second surface of the heat-generating components and applies a force towards the bottom of the placement groove.

[0010] Further, an avoidance opening is formed on the side wall of the placement groove, and the pins or connecting wires through which the heating component is connected to the outside are arranged in the avoidance opening.

[0014] Further, the limiting pressing piece includes a pressure section and a fixing section which are connected in sequence;

[0015] The pressure section is in abutting cooperation with the heating component, the fixing section is detachably connected to the heat dissipation main body, and a bending angle is formed between the pressure section and the fixing section so that the pressure section has an elastic pressure towards the bottom direction of the placement groove.

[0016] Further, screw through holes are formed in the fixing section, and the fixing section is connected to the surface of the heat dissipation main body through screws.

[0034] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but it is not limited to the present utility model.

[0035] See Figures 1 to 14As shown, according to an embodiment of the present utility model, a radiator is provided for dissipating heat from a heat-generating component A. Taking the compressor control module as an example of the heat-generating component A, the radiator includes a heat dissipation main body 10 and a limiting pressing piece 20. Refrigerant flows inside the heat dissipation main body 10, and a placement groove 11 is provided on the heat dissipation main body 10. The heat-generating component A is arranged in the placement groove 11. The limiting pressing piece 20 is detachably connected to the heat dissipation main body 10, and the limiting pressing piece 20 abuts against the heat-generating component A and restricts the movement of the heat-generating component A.

[0036] In the present utility model, a placement groove is provided on the heat dissipation main body, and the heat-generating component is arranged in the placement groove, which can prevent the heat-generating component from detaching from the heat dissipation main body due to shaking or vibration, ensuring the heat dissipation effect. At the same time, the limiting pressing piece abuts against and limits the heat-generating component, enabling the heat-generating component to be fixed in the placement groove, so that the heat-generating component and the heat dissipation main body can always remain in contact, ensuring that the heat dissipation main body can continuously and stably dissipate heat from the heat-generating component, improving the heat dissipation and cooling effect. Moreover, the limiting pressing piece is detachably connected to the heat dissipation main body, which is convenient for maintenance personnel to directly remove the limiting pressing piece during maintenance, and then the heat-generating component can be directly taken out from the placement groove. The disassembly is convenient and fast, and it also avoids the problem that the fixing structure is complex and other components are easily damaged during the disassembly process.

[0037] Preferably, the heat-generating component A has opposite first and second surfaces. The first surface of the heat-generating component A faces the bottom of the placement groove 11, and the limiting pressing piece 20 abuts against the second surface of the heat-generating component A and applies a force towards the bottom of the placement groove 11. Generally, the first and second surfaces of the heat-generating component A are the two relatively largest outer surfaces.

[0038] The heat exchange area between the first surface of the heat-generating component A and the bottom of the placement groove 11 is more sufficient, and the heat dissipation effect is better. The limiting pressing piece abuts against the second surface, and the limiting pressure is more direct, which can effectively ensure that the first surface of the heat-generating component always maintains the largest heat exchange area. On the one hand, the fixing and limiting effect is better, and on the other hand, the heat dissipation and cooling effect is improved.

[0039] Combined with Figure 3 、 Figure 4 and Figure 10 As shown, an avoidance opening 12 is formed on the side wall of the placement groove 11, and the pins or connection lines of the heat-generating component A connected to the outside are arranged in the avoidance opening 12.

[0040] Since the heat-generating component A (such as the compressor control module) needs to be connected to the outside (such as the PCB board) through pins or connecting wires, the positions of the pins or connecting wires need to be considered. The avoidance opening 12 of the present utility model can first provide a placement space for the pins or connecting wires, avoiding the problem of unstable structure caused by the over-tight installation of the heat-generating component A. At the same time, the pins or connecting wires will not be subjected to abnormal forces, avoiding unstable connections.

[0041] Further preferably, the diameter of the avoidance opening 12 is larger than the outer diameter of the heat-generating component A, and the heat-generating component A can enter or leave the placement groove 11 from the avoidance opening 12. That is to say, the heat-generating component A can be installed or disassembled from the avoidance opening 12. When it is necessary to disassemble the heat-generating component A, only need to reduce the pre-tightening force of the limit pressing piece or loosen the limit pressing piece, and take out the heat-generating component A from the avoidance opening 12 for maintenance, which simplifies the disassembly operation.

[0042] The avoidance opening 12 can not only be used for placing pins and routing wires, but also be used as a loading and unloading path and space for operation, which simplifies the disassembly steps and reduces the disassembly difficulty.

[0043] Preferably, an insulating and heat-conducting structure is connected between the first surface of the heat-generating component A and the bottom of the placement groove 11. The iron-sealed heat-generating component A (compressor control module) and the radiator are insulated through an intermediate clamping insulating and heat-conducting structure, and the electrical appliance is safe and reliable. The insulating and heat-conducting structure can adopt a variety of materials as long as it can conduct heat and insulate at the same time.

[0044] In this embodiment, the insulating and heat-conducting structure is a ceramic sheet 30, a heat-conducting silica gel is provided between the ceramic sheet 30 and the bottom of the placement groove 11, and a heat-conducting silica gel is provided between the ceramic sheet 30 and the first surface of the heat-generating component A.

[0045] See Figure 5 , the ceramic sheet 30 itself has an insulating function and a heat-conducting effect, and the structure also meets the matching relationship between the placement groove and the heat-generating component A. The heat-conducting effect is ensured by setting the heat-conducting silica gel.

[0046] During the installation process, first apply heat-conducting silica gel to the ceramic sheet and then place it in the compressor control module to fit with the radiator. Then apply heat-conducting silica gel to the iron-sealed compressor control module and place it above the ceramic sheet to fit with it. After installing the limit pressing piece (spring pressing piece), lock the screw to clamp the ceramic sheet and the iron-sealed compressor module on the radiator.

[0047] Combined with Figure 6 and Figure 7As shown, the limiting pressing piece 20 includes a pressure section 21 and a fixing section 22 connected in sequence; the pressure section 21 is in abutting cooperation with the heating component A, the fixing section 22 is detachably connected to the heat dissipation main body 10, and a bending angle is formed between the pressure section 21 and the fixing section 22 so that the pressure section 21 has an elastic pressure towards the bottom of the placement groove 11.

[0048] Through the bending angle between the pressure section and the fixing section, the limiting pressing piece 20 forms an elastic structure by itself after installation, that is, a spring pressing piece structure (which can be a Z-shaped structure). In this way, the limiting pressing piece achieves the effect of providing elastic pressure through a simple structure and cooperation, with a simple structure, small space occupation, and better heat dissipation effect.

[0049] Furthermore, screw through holes are provided on the fixing section 22, and the fixing section 22 is connected to the surface of the heat dissipation main body 10 by screw B. The present utility model realizes the fixation of the fixing section and the limiting pressing piece through a screwing connection. The advantage of the screwing connection is that when disassembly is required, the screw can be loosened to release the elastic pressure of the limiting pressing piece, so that the heating component A is disengaged from the abutting cooperation of the clamping force, and the maintenance personnel can directly disassemble the heating component A from the avoidance opening without disassembling all the structures, greatly simplifying the operation. Since the number of heating components A and the number of placement grooves are both multiple, the above-mentioned simplified operation is very necessary, improving the maintenance efficiency and facilitating disassembly.

[0050] Preferably, the value range of the bending angle α is 120° to 170°. The bending angle α can be selected as 120° and 170°. The bending angle can adjust the elastic pressure, and the most preferred is 170°. There is an interference fit of 0.2 mm between the limiting pressing piece and the compressor control module to ensure complete fit between the compressor control module and the heat dissipation main body.

[0051] Combined with Figures 8 to 14 As shown, the structure of the heat dissipation main body is introduced. The structure of the heat dissipation main body can achieve refrigerant heat dissipation through various structures. Only one structural form is introduced in this embodiment, and other conventional technical means are also the ways defined by the present utility model. Of course, in embodiments not shown in other figures, the heat dissipation main body can also be an air-cooled radiator main body structure, and the specific structure will not be elaborated.

[0052] As Figure 2 The heat dissipation main body 10 is composed of a refrigerant inlet pipe 101, a refrigerant outlet pipe 102, an upper shell, and a base. The upper shell and the base enclose a shell structure with a refrigerant channel inside. The refrigerant enters the refrigerant channel from the refrigerant inlet pipe and comes out from the refrigerant outlet pipe after passing through the internal refrigerant channel of the shell structure. The base has multiple sets of threaded holes, support columns 103, and placement grooves for installation.

[0053] Some threaded holes are used to fix the base and the upper housing, some threaded holes are used to fix the limiting pressing piece on the heat dissipation body, and some threaded holes are used to fix other heating elements on the base. The support column 103 is used to be welded on the circuit board C to fix the heat dissipation body.

[0054] The present utility model also provides an embodiment of an air conditioner, and the air conditioner includes the above-mentioned radiator.

[0055] In the present utility model, a placement groove is provided on the heat dissipation body through which the refrigerant flows, and the heating components are arranged in the placement groove, so as to prevent the heating components from detaching from the heat dissipation body due to shaking or vibration, and ensure the heat dissipation effect. At the same time, the limiting pressing piece abuts against and limits the heating components, so that the heating components can be fixed in the placement groove, and the heating components and the heat dissipation body can always remain in contact, ensuring that the heat dissipation body can continuously and stably dissipate heat from the heating components, and improving the heat dissipation and cooling effect. Moreover, the limiting pressing piece is detachably connected to the heat dissipation body, which is convenient for maintenance personnel to directly remove the limiting pressing piece during maintenance, and then the heating components can be directly taken out from the placement groove. The disassembly is convenient and fast, and it also avoids the problem that the fixing structure is complex and other components are easily damaged during the disassembly process.
