TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to an outdoor unit and a radiator thereof. BACKGROUND

[0002] The outdoor unit of the existing air conditioner is mostly cooled by air to avoid the temperature of the components in the outdoor unit being too high, which affects the use of the air conditioner. Some outdoor units are cooled by refrigerant and air, and the refrigerant pipe is arranged in the heat dissipation device, and the heat dissipation fin is fixed on the refrigerant pipe to reduce the temperature of the components in the outdoor unit.

[0003] However, in the actual construction process, there is a problem that the refrigerant pipe fixing method is relatively complex and very inconvenient in the assembly process. Therefore, it is necessary to provide a new heat dissipation device, improve the structure of the heat dissipation device, optimize the fixing method of the refrigerant pipe, and reduce the assembly difficulty. SUMMARY

[0004] Therefore, the present application provides a heat dissipation device to solve the problem that the refrigerant pipe fixing method is relatively complex and very inconvenient in the assembly process.

[0005] To solve the above problems, the present application provides a heat dissipation device for an outdoor unit, which comprises: a lining plate; a refrigerant pipe arranged on the lining plate; wherein the lining plate comprises: a fixing piece arranged on one side of the lining plate close to the refrigerant pipe, and a gap between the fixing piece and the lining plate, and the refrigerant pipe passes through the gap to be detachably fixed on the lining plate.

[0006] Compared with the prior art, the technical effects achieved by adopting the technical scheme are: a fixing piece is arranged on one side of the lining plate close to the refrigerant pipe, and a gap is formed between the fixing piece and the lining plate, so that the refrigerant pipe can pass through the gap and be detachably fixed on the lining plate. The method of fixing the refrigerant pipe is simpler and more convenient for assembly during production. At the same time, the refrigerant pipe will deform during use. The refrigerant pipe is arranged in the gap and can adapt to the deformation of the refrigerant pipe, ensuring the reliability of the refrigerant pipe fixing.

[0007] Further, the heat dissipation device further comprises: a box body, and the box body and the lining plate are mutually buckled.

[0008] Compared with the prior art, the technical effects achieved by adopting the technical scheme are: the heat dissipation device is provided with a box body, and the box body and the lining plate are mutually buckled, and the refrigerant pipe is arranged between the box body and the lining plate to prevent hard objects from entering the heat dissipation device and scratching the refrigerant pipe.

[0009] Further, the heat dissipation device further comprises: a heat dissipation piece, and the heat dissipation piece and the refrigerant pipe are mutually adhered to transfer heat between the heat dissipation piece and the refrigerant pipe.

[0010] Compared with existing technologies, the technical effects achieved by this solution are as follows: the heat sink and the refrigerant pipe are in close contact, allowing heat to be transferred between the refrigerant pipe and the heat sink. Refrigerant flows inside the refrigerant pipe, and the flow of refrigerant causes heat to dissipate, thereby reducing the temperature of the components inside the outdoor unit and improving the heat dissipation effect of the heat dissipation device.

[0011] Furthermore, the heat sink includes a mating surface, which is located on the side of the heat sink near the refrigerant pipe. The mating surface has an inclined angle in the vertical direction to correct the deformation of the refrigerant pipe.

[0012] Compared with existing technologies, the technical effects achieved by this solution are as follows: the heat dissipation component has a mating surface with an inclined angle in the vertical direction. During the operation of the outdoor unit, the refrigerant pipe will deform and detach from the fixing component. The mating surface can limit the refrigerant pipe from shifting, correct the deformation of the refrigerant pipe, and improve the stability of the heat dissipation device.

[0013] Furthermore, the heat dissipation component also includes a recess, which is located on the mating surface, and the refrigerant pipe and the recess are mated together.

[0014] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the recessed part is located on the mating surface, and the refrigerant pipe and the recessed part cooperate with each other, so that the refrigerant pipe and the recessed part can fit tightly together, promote heat transfer, and thus reduce the temperature of the components inside the outdoor unit.

[0015] Furthermore, the box body includes: a mounting hole with threads inside; and a mating hole in the liner. When the liner and the box body are fastened together, the mounting hole and the mating hole engage to fix one end of the box body to the liner.

[0016] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: the box body is provided with mounting holes, and the liner is provided with mating holes. The mating holes coincide with the mounting holes. The screws pass through the mating holes and the mounting holes and engage with the threads in the mounting holes, so that one end of the box body is fixed to the liner. The fixing method is simpler and easier to disassemble.

[0017] Furthermore, the box also includes a plug, which is located on the side of the box opposite to the mounting hole. The liner has a groove, and the plug and the groove cooperate to fix the other end of the box to the liner.

[0018] Compared with existing technologies, the technical effects achieved by this solution are as follows: the plug is located on the side of the box opposite to the mounting hole, and the plug and the groove cooperate with each other to restrict the movement of the other end of the box. The fixing method is simpler and the installation is more convenient.

[0019] Furthermore, the box body also includes: a fastener, which is located on the side of the box body near the mounting hole, and a backing part is provided on the liner. When the box body and the liner are fastened together, the fastener and the backing part abut against each other.

[0020] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the fastener is located on the side of the box body near the mounting hole, and cooperates with the abutment part of the liner to make the box body and the liner fasten together, thereby improving the stability during fastening.

[0021] Furthermore, the refrigerant pipe includes a throttle valve, which contains refrigerant and controls the flow rate of the refrigerant within the pipe.

[0022] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the refrigerant pipe is equipped with a throttling valve, which facilitates the adjustment of the refrigerant flow rate in the refrigerant pipe.

[0023] Furthermore, the present invention also provides an outdoor unit, which includes a heat dissipation device.

[0024] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The outdoor unit of the present invention has the heat dissipation device of any technical solution of the present invention, and therefore has all the beneficial effects of the heat dissipation device of any technical solution of the present invention, which will not be repeated here.

[0025] By adopting the technical solution of the present invention, the following technical effects can be achieved: (1) A fastener is provided on the side of the liner near the refrigerant pipe. There is a gap between the fastener and the liner so that the refrigerant pipe can pass through the gap and be detachably fixed on the liner. The method of fixing the refrigerant pipe is simpler and easier to assemble during production. At the same time, the refrigerant pipe will deform during use. The refrigerant pipe is set in the gap to adapt to the deformation of the refrigerant pipe and ensure the reliability of the refrigerant pipe fixing. (2) The heat sink and the refrigerant pipe are in close contact, so that heat can be transferred between the refrigerant pipe and the heat sink. Refrigerant flows in the refrigerant pipe. The refrigerant flows and causes heat to dissipate, thereby reducing the temperature of the components inside the outdoor unit and improving the heat dissipation effect of the heat sink. (3) The heat dissipation component has a mating surface with an inclined angle in the vertical direction. During the operation of the outdoor unit, the refrigerant pipe will deform and detach from the fixing component. The mating surface can limit the refrigerant pipe from shifting, correct the deformation of the refrigerant pipe, and improve the stability of the heat dissipation device.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] This invention provides a heat dissipation device 100, which is used on an outdoor unit, as shown in the attached figure. Figure 1 As shown, the heat dissipation device 100 includes: a liner 100 and a refrigerant pipe 130. The refrigerant pipe 130 is disposed on the liner 110. The liner 110 includes: a fixing member 111. The fixing member 111 is disposed on the side of the liner 110 near the refrigerant pipe 130. There is a gap between the fixing member 111 and the liner 110. The refrigerant pipe 130 passes through the gap so that the refrigerant pipe 130 is detachably fixed on the liner 110.

[0030] For details, please see the attached document. Figure 2 As shown, the liner 110 is provided with a fastener 111, and there is a gap between the fastener 111 and the liner 110. One end of the fastener 111 is provided with a flared end, which makes it easy for the refrigerant pipe 130 to pass through the gap from the bottom. This allows the fastener 111 to fix the refrigerant pipe 130 to the liner 110, making the method of fixing the refrigerant pipe 130 simpler and easier to assemble during the production process. At the same time, the refrigerant pipe 130 may deform during use. The refrigerant pipe 130 is placed in the gap to accommodate the deformation of the refrigerant pipe 130, ensuring the reliability of the fixation of the refrigerant pipe 130.

[0031] Supplementary explanation, as attached Figure 2As shown, there are two fasteners 111, and both fasteners 111 have flared openings, which makes the force on the refrigerant pipe 120 more balanced and the fixation more reliable, preventing the refrigerant pipe 130 from detaching from the fasteners 111.

[0032] For example, the heat dissipation device 100 also includes a housing 120, which is interlocked with the liner 110.

[0033] For example, see attached. Figure 1 As shown, the heat dissipation device 100 is provided with a box 120, which is fastened to the liner 110, so that the refrigerant pipe 130 is located between the box 120 and the liner 110, preventing hard objects from entering the heat dissipation device 100 and damaging the refrigerant pipe 120.

[0034] Specifically, the heat dissipation device 100 also includes a heat sink 140, which is in contact with the refrigerant pipe 130 so that heat can be transferred between the heat sink 140 and the refrigerant pipe 130.

[0035] Specifically, as shown in the appendix Figure 1 As shown, the heat dissipation device 100 is provided with a heat dissipation component 140, which is in close contact with the refrigerant pipe 130, so that heat can be transferred between the refrigerant pipe 130 and the heat dissipation component 140. Refrigerant flows in the refrigerant pipe 130. The flow of refrigerant causes heat to dissipate, thereby reducing the temperature of the components inside the outdoor unit and improving the heat dissipation effect of the heat dissipation device 100.

[0036] For example, the heat sink 140 also includes a mating surface 141, which is located on the side of the heat sink 140 near the refrigerant pipe 130, and the mating surface 141 has an inclined angle in the vertical direction.

[0037] For example, see attached. Figure 5 As shown, the heat sink 140 is provided with a mating surface 141. The mating surface 141 has an inclined angle in the vertical direction, so that the mating surface 141 can cooperate with the refrigerant pipe 130. During the operation of the outdoor unit, the refrigerant pipe 130 will deform and then detach from the fixing part 111. The mating surface 141 can limit the refrigerant pipe 130 from shifting, correct the deformation of the refrigerant pipe 130, and improve the stability of the heat sink 100.

[0038] Specifically, the heat sink 140 also includes a recess 142, which is provided on the mating surface 141, and the refrigerant pipe 130 is in contact with the recess 142.

[0039] Specifically, as shown in the appendix Figure 4 As shown, the heat sink 140 has a recess 142, as indicated in the attached diagram. Figure 5As shown, the refrigerant pipe 130 is disposed in the recessed portion 142 and fits into the recessed portion 142, so that the refrigerant pipe 130 and the heat sink 140 are in close contact, which promotes the heat transfer between the refrigerant pipe 130 and the heat sink 140, thereby reducing the temperature of the components inside the outdoor unit and ensuring the normal operation of the outdoor unit.

[0040] For example, the box body includes: a mounting hole 121, the mounting hole 121 being threaded; wherein, the liner 110 is provided with a mating hole 112, when the liner 110 and the box body 120 are fastened together, the mounting hole 121 and the mating hole 112 are mated together to fix one end of the box body 120 onto the liner 110.

[0041] For example, see attached. Figure 5 As shown, the housing 120 has mounting holes 121, as per the attached diagram. Figure 3 As shown, the liner 110 is provided with a mating hole 112, which coincides with the mounting hole 121. The screw passes through the mating hole 112 and the mounting hole 121 and engages with the thread in the mounting hole 121, so that one end of the box 120 is fixed on the liner 110. The fixing method is simpler and easier to disassemble.

[0042] Specifically, the box body 120 also includes: a plug 122, which is located on the side of the box body 120 opposite to the mounting hole 121; wherein, the liner 110 is provided with a groove 113, and the plug 122 and the groove 113 cooperate with each other to fix the other end of the box body 120 onto the liner 110.

[0043] Specifically, as shown in the appendix Figure 5 As shown, the box 120 is provided with a plug 122. The plug 122 is located on the side of the box 120 opposite to the mounting hole 121. The plug 122 and the groove 113 cooperate with each other to restrict the movement of the other end of the box 120. The fixing method is simpler and the installation is more convenient.

[0044] Supplementary explanation, as attached Figure 5 As shown, the box body 120 is provided with two inserts 122. One insert 122 cooperates with the groove 113, and the other insert 122 cooperates with the fastener 111, as shown in the attached figure. Figure 2 As shown, there are two fasteners 111. Another plug 122 cooperates with the fastener 111 located near the groove 113 to fix the box body 120 on the liner 110.

[0045] For example, the box body 120 also includes a fastener 123, which is located on the side of the box body 120 near the mounting hole 121. The liner 110 is provided with an abutment part 114. When the box body 120 and the liner 110 are fastened together, the fastener 123 and the abutment part 114 abut against each other.

[0046] For example, see attached. Figure 5 As shown, the box body 120 is provided with a fastener 123, and there is a gap between the fastener 123 and the box body 120, as shown in the attached figure. Figure 2 As shown, the liner 110 is provided with an abutment part 114. When the box body 120 and the liner 110 are fastened together, the abutment part 114 extends into the gap between the buckle 123 and the box body 120, so that the box body 120 and the liner 110 are fastened together, making the heat dissipation device 100 more stable.

[0047] Specifically, the refrigerant pipe 130 also includes a throttle valve 131. The refrigerant pipe 130 contains refrigerant, and the throttle valve 131 controls the flow rate of the refrigerant in the refrigerant pipe 130.

[0048] Specifically, as shown in the appendix Figure 1 As shown, the throttle valve 131 is installed on the refrigerant pipe 130 to facilitate the adjustment of the refrigerant flow rate in the refrigerant pipe 130.

[0049] The present invention also provides an outdoor unit, which includes a heat dissipation device 100.

[0050] Specifically, the outdoor unit of the present invention has the heat dissipation device 100 of any technical solution of the present invention, and therefore has all the beneficial effects of the heat dissipation device 100 of any technical solution of the present invention, which will not be repeated here.

[0051] Supplementary explanation, as attached Figure 1 As shown, the outdoor unit includes: a controller 200 and a heat dissipation device 100 for dissipating heat from the controller 200, so as to prevent the controller 200 from overheating and affecting the normal operation of the outdoor unit, thus improving the user experience.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
