Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioner technology, and in particular to a heat dissipation device, an outdoor unit of an air conditioner, and an air conditioner. Background Technology
[0002] During operation, air conditioners require numerous electrical components to function properly, including cooling and heating. These components generate a significant amount of heat, which must be dissipated promptly. Otherwise, the air conditioner's power consumption will increase, its performance will decrease, and it may even shut down and malfunction.
[0003] Currently, in existing technology, air conditioners dissipate heat from their electrical components through natural convection or forced convection by fans. However, when the environment is harsh (e.g., high ambient temperature or blocked convection channels), the cooling effect of air-cooled systems becomes very poor and insufficient to meet the cooling needs of the air conditioner's electrical components. In such cases, the air conditioner will still experience increased power consumption, decreased performance, or even shutdown. This significantly diminishes the user experience. Utility Model Content

[0050] In the description of this embodiment, the terms "embodiment," "modified embodiment," "implementation," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0051] The following is combined with Figures 1 to 3 The heat dissipation device of this embodiment will be described in detail below.
[0052] Reference Figure 1 In this embodiment, the heat dissipation device 100 can be used to dissipate heat from the electrical components 200 of the air conditioner, and the heat dissipation device 100 may include a heat sink 110 and a water supply component 130.
[0053] The heat sink 110 includes a heat sink substrate 111 and heat sink fins 112 connected below the heat sink substrate 111. The heat sink substrate 111 is used to mount the electrical components 200 of the air conditioner.
[0054] The water supply component 130 is disposed on the heat dissipation component 110. The water supply component 130 is provided with a water outlet 131. The water supply component 130 is used to receive the condensate generated by the air conditioner and discharge the condensate to the heat dissipation fins 112 through the water outlet 131, so as to remove the heat from the heat dissipation component 110 and the electrical components 200 through the condensate.
[0055] Since the heat dissipation device 100 of this embodiment has a heat sink 110 for dissipating heat from the electrical component 200 and a water supply component 130, and the water supply component 130 is provided with a water outlet 131, the water supply component 130 can discharge the condensate water generated by the air conditioner to the heat dissipation fins 112. The condensate water carries away the heat on the heat sink 110, thereby achieving water-cooled heat dissipation of the electrical component 200. Therefore, the heat dissipation device 100 of this embodiment can use the condensate water generated by the air conditioner itself to dissipate heat from the electrical component 200, improving the heat dissipation effect of the electrical component 200. This allows the air conditioner to work normally even in harsh environments and has good performance, thus ensuring a good user experience.
[0056] It should be noted that the temperature of the condensate produced by the air conditioner in cooling mode can reach approximately 10°C, which can effectively remove heat from the heat sink 110 and improve the heat dissipation effect of the heat sink 110 on the electrical component 200. Furthermore, the electrical component 200 can be from the air conditioner controller. The electrical component 200 can be a rectifier bridge, an IGBT (Insulated-Gate Bipolar Transistor), a diode, and / or an IPM (Intelligent Power Module).
[0057] It is also important to understand that by setting the heat dissipation substrate 111 and the heat dissipation fins 112 as an upper and lower structure, the condensation on the heat dissipation fins 112 can be prevented from flowing to the heat dissipation substrate 111 and then to the electrical components 200, so as to ensure the normal operation of the electrical components 200 and the air conditioner.
[0058] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the water outlet 131 is disposed adjacent to and facing the heat dissipation fins 112, so that the condensate flowing out of the water outlet 131 flows onto the heat dissipation fins 112.
[0059] It is understandable that by arranging the water outlet 131 adjacent to and facing the heat dissipation fins 112, the condensate flowing out of the water outlet 131 can naturally flow onto the heat dissipation fins 112, thereby achieving water-cooled heat dissipation of the electrical component 200 and improving the heat dissipation effect of the electrical component 200.
[0060] In some other embodiments, the water supply component 130 may be disposed on the heat dissipation substrate 111 or be an integral component of the heat dissipation substrate 111. Furthermore, the water outlet 131 may be disposed adjacent to the heat dissipation fins 112 and formed at the bottom end of the water supply component 132. Similarly, the condensate flowing out of the water outlet 131 can naturally flow onto the heat dissipation fins 112, achieving water-cooled heat dissipation of the electrical component 200 and improving the heat dissipation effect of the electrical component 200.
[0061] In some other embodiments, the water outlet 131 can transport the condensate in the water supply component 130 to the heat dissipation fins 112 through the pipe body. Similarly, water cooling can be achieved for the electrical component 200, thereby improving the heat dissipation effect of the electrical component 200.
[0062] Specifically, one end of the pipe can be connected to the water outlet 131, and the other end of the pipe can be positioned adjacent to and facing the heat dissipation fins 112.
[0063] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the water supply component 130 may include a water supply section 132. The water supply section 132 is disposed on the heat dissipation fins 112, and the water outlet section 131 is formed on the side of the water supply section 132 facing the fin surface of the heat dissipation fins 112.
[0064] The water outlet 131 is disposed relative to the fin surface of the heat dissipation fin 112. The heat dissipation fin 112 has a first end 121 and a second end 122 arranged opposite to each other in the transverse direction. The water supply part 132 is disposed between the first end 121 and the second end 122, and the water outlet 131 is disposed between the first end 121 and the second end 122.
[0065] Understandably, since the heat dissipation fins 112 have a large surface area, the water outlet 131 can be positioned facing the surface of the heat dissipation fins 112. This allows the heat dissipation fins 112 to effectively collect the condensate flowing from the water outlet 131, ensuring good contact between the condensate and the heat dissipation fins 112, and further guaranteeing the heat dissipation effect on the electrical components 200.
[0066] In some other embodiments, the water outlet 131 may be disposed relative to the first end 121 and / or the second end 122 of the heat dissipation fin 112 (e.g., disposed on the inner side of the connection portion 133 or the water inlet portion 134 toward the heat dissipation fin 112), and similarly, the condensate flowing out of the water outlet 131 may flow onto the heat dissipation fin 112.
[0067] Reference Figure 1 , Figure 2 and Figure 3In this embodiment, the water supply component 130 can be configured as a water storage box; and the water outlet 131 can be configured on the top of the water supply component 132 so that after the water supply component 132 is filled with condensate, the condensate flows to the heat dissipation fins 112.
[0068] Understandably, by configuring the water supply unit 130 as a water storage box, condensate will only flow out of the water outlet 131 when the water supply section 132 is full. In this way, when the heat dissipation device 100 uses condensate to cool the electrical components 200, the flow rate of condensate to the heat dissipation fins 112 is always sufficient. Furthermore, it should be noted that compared to placing the water outlet 131 at the bottom of the water supply section 132, the condensate flows or remains in the water storage box for a longer time, thus allowing the heat dissipation device 100 to achieve better heat dissipation performance.
[0069] In some other embodiments, the water outlet 131 can be located at the bottom of the water supply section 132, so that when the water supply section 132 receives the condensate from the air conditioner, the condensate can flow directly to the heat dissipation fins 112 through the water outlet 131, ensuring that the heat dissipation device 100 can dissipate heat from the electrical components 200 in a timely manner.
[0070] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the water supply section 132 is disposed in contact with the fin surface of the heat dissipation fin 112 to allow heat exchange between the water supply section 132 and the heat dissipation fin 112.
[0071] It is understandable that by positioning the water supply section 132 in contact with the surface of the heat dissipation fins 112, the heat dissipation device 100, in addition to dissipating condensate to the heat dissipation fins 112 to cool the electrical components 200, can also exchange heat between the water supply section 132 and the heat dissipation fins 112, further ensuring the heat dissipation effect on the electrical components 200. Furthermore, by configuring the water supply section 132 as a water storage box, condensate is always stored within the water supply section 132, thus maintaining a constant supply of cold energy for heat exchange with the heat dissipation fins 112, further ensuring the heat dissipation effect of the heat dissipation device 100 on the electrical components 200.
[0072] In addition, the material of the water supply unit 132 can be a material with good thermal conductivity, such as copper, aluminum, iron, or steel.
[0073] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the water supply section 132 may extend between the first end 121 and the second end 122.
[0074] It is understandable that the water supply section 132 extends between the first end 121 and the second end 122, which ensures the contact area between the water supply section 132 and the heat dissipation fins 112, thereby further ensuring the heat dissipation effect of the heat dissipation device 100 on the electrical components 200. Furthermore, the extension of the water supply section 132 provides a basis for the extension of the water outlet section 131.
[0075] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the water supply section 132 may be a strip-shaped structure that extends between the first end 121 and the second end 122, and the water supply section 132 has a space for the flow and / or storage of condensate.
[0076] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the water supply section 132 is disposed adjacent to the heat dissipation substrate 111 so as to cause the condensate flowing out of the water outlet section 131 to flow to the top of the heat dissipation fins 112.
[0077] It is understandable that, since the water outlet 131 is located on top of the water supply section 132, and the water supply section 132 is adjacent to the heat dissipation substrate 111, the condensate flowing out of the water outlet 131 can flow to the top of the heat dissipation fins 112 and flow from the top to the bottom of the heat dissipation fins 112 to ensure the contact time between the condensate and the heat dissipation fins 112, thereby further ensuring the heat dissipation effect of the heat dissipation device 100 on the electrical components 200.
[0078] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the water outlet 131 can be extended between the first end 121 and the second end 122.
[0079] It is understandable that the water outlet 131 extends between the first end 121 and the second end 122, thus allowing the water outlet 131 to have a larger water outlet area and a larger water outlet volume, further ensuring the heat dissipation effect of the heat dissipation device 100 on the electrical component 200. Furthermore, the extension of the water outlet 131 between the first end 121 and the second end 122 allows condensate to come into greater contact with the heat dissipation fins 112 between the first end 121 and the second end 122, ensuring a larger contact area between the condensate and the heat dissipation fins 112, thereby further ensuring the heat dissipation effect of the heat dissipation device 100 on the electrical component 200.
[0080] Reference Figure 1 , Figure 2 and Figure 3In this embodiment, the water outlet 131 may include a water outlet 1311 extending between the first end 121 and the second end 122, so that the condensate in the water outlet 131 can flow to the heat dissipation fins 112.
[0081] In a modified embodiment of the water outlet 131, the water outlet 131 may include a plurality of water outlets 1311 arranged between the first end 121 and the second end 122. Similarly, the condensate in the water outlet 131 can flow to the heat dissipation fins 112.
[0082] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the number of heat dissipation fins 112 is set to multiple, and the multiple heat dissipation fins 112 are arranged at intervals along a predetermined direction; and the number of water supply parts 132 is set to multiple, and the multiple water supply parts 132 are arranged alternately with the multiple heat dissipation fins 112.
[0083] It is understandable that by alternately arranging multiple heat dissipation fins 112 and water supply units 132, the heat dissipation effect of the heat dissipation device 100 on the electrical components 200 can be further improved.
[0084] Furthermore, the heat dissipation fins 112 are arranged at intervals along a predetermined direction, which can be that the fin surfaces of the heat dissipation fins 112 are arranged at intervals facing each other. And, the predetermined direction can be a left-right direction.
[0085] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the water supply section 132 located between any two heat dissipation fins 112 may have water outlets 131 on the sides facing the fin surfaces of the two heat dissipation fins 112. That is, the water supply section 132 has water outlets 131 on both sides facing the fin surfaces of the heat dissipation fins 112. Furthermore, condensate can flow on both fin surfaces of a single heat dissipation fin 112 to further ensure the heat dissipation effect of the heat dissipation device 100 on the electrical components 200.
[0086] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the water supply component 130 may further include a connecting portion 133. The connecting portion 133 is connected to a plurality of water supply portions 132 and is used to balance the amount of condensate water among the plurality of water supply portions 132.
[0087] It is understandable that the connection part 133 can make the water storage height between the multiple water supply parts 132 consistent, so the amount of condensate flowing out of the water outlet part 131 is consistent, and thus the heat dissipation performance of each heat dissipation fin 112 is consistent, thus ensuring the heat dissipation performance of the heat dissipation device 100.
[0088] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the connecting part 133 is disposed at the first end 121, and the connecting part 133 is located on the outside of the plurality of heat dissipation fins 112.
[0089] It is understandable that the multiple water supply units 132 are connected by a connecting part 133 provided on the outside of the multiple heat dissipation fins 112, so that the water volume balance between the water supply units 132 can be achieved without (destructive) modification of the heat dissipation fins 112.
[0090] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the water supply component 130 may further include a water inlet 134. The water inlet 134 is connected to a plurality of water supply components 132. The water inlet 134 is disposed at the second end 122 and is located outside the plurality of heat dissipation fins 112. The water inlet 134 is provided with a water inlet 1341 for allowing condensate to enter the water supply component 130, and the water inlet 134 is inclined downward from the water inlet 1341 to the second end 122.
[0091] Understandably, the water inlet 134 is configured to deliver the received condensate from the air conditioner to the water supply section 132. Furthermore, the water inlet 134 can be located outside the second end 122 of the heat dissipation fins 112, and is connected to the connecting part 133 in a wrapping manner with the multiple heat dissipation fins 112. The connecting part 133 can contact the first end 121, and the water inlet 134 can contact the second end 122. Therefore, heat exchange can also occur between the water supply component 130 and the multiple heat dissipation fins 112 through the first end 121 and the second end 122 of the heat dissipation fins 112, further improving the heat dissipation effect of the heat dissipation device 100 on the electrical components 200.
[0092] In addition, the size of the water inlet 134 gradually decreases from the second end 122 to the water inlet 1341, that is, the water inlet 134 has a conical structure.
[0093] Reference Figure 1 , Figure 2 and Figure 3 In the first embodiment where the water supply component 130 is installed on the heat dissipation fins 112, corresponding and relatively extending first limiting structures 1321 and second limiting structures 1322 are respectively provided on the opposite sides of two adjacent water supply parts 132, and the relatively extending first limiting structures 1321 and second limiting structures 1322 respectively abut against the fin surfaces on both sides of the heat dissipation fins 112.
[0094] It is understandable that the water supply component 130 is mounted on the heat dissipation fins 112 in a manner that can be achieved by clamping the heat dissipation fins 112 with the relatively extended first limiting structure 1321 and second limiting structure 1322. Specifically, the first limiting structure 1321 and the second limiting structure 1322 can restrict the downward movement of the water supply component 130 as a whole.
[0095] In the second embodiment where the water supply component 130 is installed on the heat dissipation fin 112, one of the two adjacent water supply parts 132 is provided with a first limiting structure 1321 that protrudes towards the other, and the first limiting structure 1321 abuts against one fin surface of the heat dissipation fin 112 between the two adjacent water supply parts 132, and the other water supply part 132 contacts the other fin surface of the heat dissipation fin 112, so as to achieve the installation of the water supply component 130 on the heat dissipation fin 112 in the same way.
[0096] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, both the first limiting structure 1321 and the second limiting structure 1322 can be limiting protrusions. Furthermore, the number of limiting protrusions can be set to multiple, and these multiple limiting protrusions can be arranged along the direction of the first end 121 and the second end 122.
[0097] In some other embodiments of the first limiting structure 1321 and the second limiting structure 1322, the limiting structure may be a limiting protrusion, and the limiting protrusion is arranged along the direction of the first end 121 and the second end 122.
[0098] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the first limiting structure 1321 and the second limiting structure 1322 can be arranged above the water outlet 131 to avoid interference with the flow of condensate water from top to bottom on the heat dissipation fins 112, so as to further ensure the heat dissipation effect of the heat dissipation device 100 on the electrical components 200.
[0099] In a modified embodiment, the difference from the above embodiment is that the water supply component 130 can be an interconnected pipe structure. That is, the water supply section 132 can be a water supply pipe extending between the first end 121 and the second end 122, the water inlet section 134 can be a water inlet pipe extending along the arrangement direction of the plurality of heat dissipation fins 112, and the water inlet pipe is connected to the plurality of water supply pipes, and the connecting section 133 can be a connecting pipe extending along the arrangement direction of the plurality of heat dissipation fins 112, and the connecting pipe is connected to the plurality of water supply pipes. The water supply pipe, the water inlet pipe, and the connecting pipe can be connected to the heat dissipation substrate 111 or the heat dissipation fins 112, and the connection method can be adhesive bonding or clamp connection, or the materials of the water supply pipe, the water inlet pipe, and the connecting pipe are all metal with the materials of the heat dissipation substrate 111 or the heat dissipation fins 112, and can be an integral structure or welded.
[0100] The following is combined with Figure 4 The outdoor unit 300 of the air conditioner in this embodiment will be described in detail below.
[0101] Reference Figure 4 In this embodiment, the outdoor unit 300 of the air conditioner may include the heat dissipation device 100 and the housing 310 described in the above embodiments. The heat dissipation device 100 may be disposed within the housing 310.
[0102] It is understandable that, since the compressor in the air conditioner's refrigeration system is installed inside the casing 310 of the outdoor unit 300, the compressor requires a large current, resulting in a significant amount of heat generated by the electrical components 200 of the outdoor air conditioner. Furthermore, during summer operation in cooling mode, if the outdoor ambient temperature is high, the electrical components 200 experience poor heat dissipation, causing the air conditioner to frequently shut down. Therefore, the radiator in the above embodiment can be installed on the outdoor air conditioner to dissipate heat from the electrical components 200 of the outdoor unit 300 (e.g., the controller installed on the outdoor unit 300). Moreover, the outdoor unit 300 of this embodiment, having the heat dissipation device 100 of the above embodiment, also possesses the beneficial technical effects of the heat dissipation device 100 of the above embodiment.
[0103] Reference Figure 4 In this embodiment, the housing 310 is provided with a heat exchange chamber 311 for accommodating an outdoor fan 320 and an outdoor heat exchanger 330. The heat dissipation device 100 is disposed in the heat exchange chamber 311. An air inlet and an air outlet 312 are respectively provided on the front and rear walls of the housing 310. The first end 121 and the second end 122 of the heat dissipation fins 112 are arranged in the front-rear direction, that is, multiple heat dissipation fins 112 are arranged in the left-right direction, so as to facilitate the heat dissipation airflow formed by the outdoor fan 320, the air inlet and the air outlet 312 to flow through the heat dissipation fins 112.
[0104] It is understood that the heat dissipation device 100 can be installed inside the heat exchange chamber 311, with the first end 121 and the second end 122 of the heat dissipation fins 112 arranged in the front-to-back direction. The outdoor fan 320 then causes the airflow flowing from the air inlet into the housing 310 to pass over the heat dissipation fins 112, carrying away the heat from the fins and exiting the housing 310 from the air outlet 312. Therefore, in this embodiment, the heat dissipation device 100 can not only dissipate heat from the electrical components 200 using condensate water, but also cooperate with the outdoor air conditioning unit 300 to provide air-cooled heat dissipation for the electrical components 200, further ensuring the heat dissipation effect of the heat dissipation device 100 on the electrical components 200.
[0105] In addition, after the condensate flowing out of the water outlet 131 flows through the heat dissipation fins 112, that is, after the heat dissipation device 100 uses the condensate to dissipate heat from the electrical components 200, the condensate flowing down from the heat dissipation fins 112 can drip into the heat exchange chamber 311 and drip into the outdoor space from the gap at the bottom of the heat exchange chamber 311.
[0106] Reference Figure 4 In this embodiment, as the condensate drips from the heat dissipation fins 112 onto the bottom of the heat exchange chamber 311, the outdoor fan 320 can also be used to disperse the condensate and cause the dispersed condensate and the mixed fluid of the heat dissipation airflow to flow together over the outdoor heat exchanger 330, the heat dissipation fins 112 of the heat dissipation device 100 and / or be discharged from the air outlet 312 into the outdoor space.
[0107] It should be understood that when the outdoor fan 320 disperses the condensate and promotes its flow to the outdoor heat exchanger 330, it can improve the performance of the outdoor heat exchanger 330; when it promotes its flow to the heat dissipation fins 112 of the heat dissipation device 100, it can improve the heat dissipation performance of the heat dissipation device 100 on the electrical components 200; and when it promotes its flow from the air outlet 312 to the outdoor space, it can prevent the condensate from remaining in the outdoor unit 300 of the air conditioner.
[0108] In some other embodiments, an air conditioner indoor unit 400 is also provided, and a heat dissipation device 100 can be installed in the air conditioner indoor unit 400 to dissipate heat from the electrical components 200 disposed in the air conditioner indoor unit 400, ensuring the normal operation of the air conditioner, improving the performance of the air conditioner, and ensuring the user experience. Therefore, the air conditioner indoor unit 400 in this embodiment also possesses the beneficial technical effects of the heat dissipation device 100 in the above embodiments.
[0109] The following is combined with Figure 5 The air conditioner in this embodiment will be described in detail below.
[0110] Reference Figure 5In this embodiment, the air conditioner includes an indoor unit 400, a heat dissipation device 100 as described in the above embodiment, a water pipe 510, a water purification module 520, a water storage tank 530, and a water pump 540. One end of the water pipe 510 is connected to the water inlet 1341 of the heat dissipation device 100, and the other end of the water pipe 510 is connected to the indoor unit 400. The water pipe 510 is used to transport the condensate generated by the indoor unit 400 to the water supply component 130 through the water inlet 1341.
[0111] Furthermore, the water purification module 520, the water storage tank 530, and the water pump 540 are sequentially connected to the water supply pipe 510 from the indoor unit 400 of the air conditioner to the water inlet 1341. The water pump 540 is used to supply the condensate in the water storage tank 530 to the water outlet, so as to enable the heat dissipation device 100 to dissipate heat from the electrical components 200.
[0112] It is understandable that when the air conditioner is running in cooling / dehumidification mode in summer, a large amount of condensate will be generated on the indoor heat exchanger of the indoor unit 400. Therefore, the condensate of the heat dissipation device 100 in the above embodiment can be generated by the indoor unit 400, and this condensate can be collected by the water collection tray of the indoor unit 400 and transported to the water outlet of the heat dissipation device 100 through the water pipe 510. Thus, the bulk device in the above embodiment can use the condensate to dissipate heat from the electrical components 200. Furthermore, the water purification module 520 ensures the cleanliness of the condensate flowing into the water outlet, guaranteeing the heat dissipation effect of the heat dissipation device 100 on the electrical components 200. In addition, the water storage tank 530 can store condensate when the heat dissipation device 100 does not need to use condensate to dissipate heat from the electrical components 200, for use when the electrical components 200 need condensate for heat dissipation.
