The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0053] Reference is made below Figures 1-8 to describe the outdoor unit 100 and the air conditioning equipment according to an embodiment of the present utility model.

[0054] Referring to Figures 1-8 , the outdoor unit 100 according to an embodiment of the first aspect of the present utility model includes: an outdoor unit housing 1, an outdoor heat exchanger 2, an outdoor fan, a compressor assembly 3, and an electronic control box component 4 provided in the outdoor unit housing 1.

The outdoor heat exchanger 2 and the outdoor fan are provided in the blower chamber 12, the compressor assembly 3 is provided in the compressor chamber 13, and at least a part of the electronic control box component 4 is located in the compressor chamber 13.

[0055] Among them, at least a part of the electronic control box component 4 being located in the compressor chamber 13 may include the following several situations: for example, a part of the electronic control box component 4 is located in the compressor chamber 13, and another part of the electronic control box is located in the blower chamber 12; for another example, the electronic control box component 4 is entirely located in the compressor chamber 13.

[0056] An air inlet 14 and an air outlet 15 communicating with the blower chamber 12 are formed on the outdoor unit housing 1. During the operation of the outdoor fan, the outdoor fan can drive air flow to enter the outdoor unit housing 1 from the air inlet 14, exchange heat with the outdoor heat exchanger 2, and then be discharged to the outside of the outdoor unit housing 1 through the air outlet 15 after heat exchange.

[0057] The compressor assembly 3 includes a compressor, and the compressor assembly 3 can play a role in compressing and driving the refrigerant in the refrigerant circulation loop of the outdoor unit 100.

[0058] The electronic control box component 4 includes an electronic control module 42 and a heat dissipation plate 8. The heat dissipation plate 8 is used to dissipate heat from the electronic control module 42. The heat dissipation plate 8 is thermally connected to the electronic control module 42. The heat dissipation plate 8 has a heat dissipation flow channel 83 for the flow of a heat exchange medium. The heat exchange medium flowing in the heat dissipation flow channel 83 is in direct contact with the heat dissipation plate 8. If the heat exchange medium in the heat dissipation flow channel 83 is in indirect contact with the heat dissipation plate 8, for example, the heat exchange medium is accommodated in a heat dissipation pipe 7 channel, and the heat dissipation pipe 7 channel is accommodated in the heat dissipation flow channel 83, the heat transfer between the heat dissipation plate 8 and the heat exchange medium needs to be indirectly transferred through the heat dissipation pipe 7 channel. By having the heat dissipation flow channel 83 for the flow of the heat exchange medium in the heat dissipation plate 8 and making the heat exchange medium flowing in the heat dissipation flow channel 83 be in direct contact with the heat dissipation plate 8, the heat dissipation plate 8 and the heat exchange medium in the heat dissipation flow channel 83 can directly transfer heat, which is beneficial to improving the heat exchange effect between the heat exchange medium and the heat dissipation plate 8, and thus beneficial to improving the heat dissipation effect of the heat dissipation plate 8 on the electronic control module 42.

[0059] Optionally, the heat dissipation plate 8 can further be cooled by air cooling or refrigerant cooling.

[0060] Optionally, the electronic control box component 4 further includes a first bracket 91. The heat dissipation plate 8 is installed on the first bracket 91, and the first bracket 91 is installed on the electronic control module 42.

[0061] For the outdoor unit 100 according to the embodiment of the present invention, by making the heat dissipation plate 8 have a heat dissipation flow channel 83 for the flow of a heat exchange medium and making the heat exchange medium flowing in the heat dissipation flow channel 83 be in direct contact with the heat dissipation plate 8, it is beneficial to improve the heat exchange efficiency and heat exchange effect between the heat exchange medium and the heat dissipation plate 8, and thus beneficial to improving the heat dissipation effect of the heat dissipation plate 8 on the electronic control module 42. Furthermore, it can reduce or avoid the situation where the electronic control module 42 is in a high-temperature working condition and has an adverse effect on the working ability of the outdoor unit 100, and reduce or avoid the situation where it has an adverse effect on the air-conditioning ability of the air-conditioning equipment.

[0062] Reference Figures 3-8 , according to some embodiments of the present invention, the heat dissipation plate 8 has a flow channel inlet 831 and a flow channel outlet 832 communicating with the heat dissipation flow channel 83. The flow channel inlet 831 and the flow channel outlet 832 are located on one side of the heat dissipation plate 8 in the length direction. The heat exchange medium enters the heat dissipation flow channel 83 through the flow channel inlet 831, exchanges heat with the heat dissipation plate 8 to take away the heat on the heat dissipation plate 8, and then flows out of the heat dissipation flow channel 83 through the flow channel outlet 832. By making the flow channel inlet 831 and the flow channel outlet 832 be located on one side of the heat dissipation plate 8 in the length direction, it is convenient to connect the external pipeline of the heat exchange medium to the heat dissipation plate 8 on the same side of the heat dissipation plate 8, which is beneficial to improving the production and assembly efficiency.

[0063] Reference Figures 3-8, according to some alternative embodiments of the present utility model, the flow channel inlet 831 and the flow channel outlet 832 are arranged along the width direction of the heat dissipation plate 8. By arranging the flow channel inlet 831 and the flow channel outlet 832 along the width direction of the heat dissipation plate 8, the arrangement of the flow channel inlet 831 and the flow channel outlet 832 is reasonable, and such an arrangement can make the heat dissipation flow channel 83 occupy a larger area within the heat dissipation plate 8, which is beneficial to further improving the heat exchange effect of the heat dissipation plate 8 on the electronic control module 42.

[0064] Reference Figures 7-8 , according to some embodiments of the present utility model, the heat dissipation flow channel 83 includes a first flow channel section 834 and a second flow channel section 835. The first flow channel section 834 extends along the length direction of the heat dissipation plate 8. The first flow channel sections 834 are multiple and arranged at intervals along the width direction of the heat dissipation plate 8. The second flow channel section 835 is connected between the same ends of two adjacent first flow channel sections 834 along the length direction of the heat dissipation plate 8. For example, the number of the first flow channels can be two, four, six, etc., and a second flow channel is connected between two adjacent first flow channels. For example, the heat dissipation flow channel 83 is formed in a U shape and includes two first flow channels and a second flow channel connected between the two first flow channels. Such a setting makes the arrangement of the heat dissipation flow channel 83 on the heat dissipation plate 8 regular, and makes full use of the space on the heat dissipation plate 8, which is beneficial to improving the heat dissipation effect of the heat exchange medium on the heat dissipation plate 8, and thus beneficial to improving the heat dissipation effect of the heat dissipation plate 8 on the electronic control module 42.

[0065] Reference Figures 3-8 , according to some embodiments of the present utility model, the heat dissipation plate 8 includes a connected first heat dissipation plate 81 and a second heat dissipation plate 82. The heat dissipation flow channel 83 is formed on the first heat dissipation plate 81, or the heat dissipation flow channel 83 is formed on the second heat dissipation plate 82, or the first heat dissipation plate 81 and the second heat dissipation plate 82 jointly define the heat dissipation flow channel 83. The setting position of the heat dissipation flow channel 83 is flexible, and the setting position of the heat dissipation flow channel 83 can be flexibly adjusted according to the heat dissipation requirements of the electronic control module 42 and the structure of the heat dissipation plate 8. In this way, the heat dissipation plate 8 can better match different electronic control box components 4.

[0066] Optionally, the heat dissipation flow channel 83 is formed on both the first heat dissipation plate 81 and the second heat dissipation plate 82.

[0067] Reference Figures 3-8 , according to some alternative embodiments of the present utility model, the first heat dissipation plate 81 and the second heat dissipation plate 82 are detachably connected. By making the first heat dissipation plate 81 and the second heat dissipation plate 82 detachably connected, it is convenient to perform inspections, maintenance, replacements, etc. on the first heat dissipation plate 81 and the second heat dissipation plate 82 respectively.

[0068] Reference Figures 4-8According to some optional embodiments of the utility model, the surface of the first heat sink 81 facing the second heat sink 82 is the first surface 811, and the surface of the second heat sink 82 facing the first heat sink 81 is the second surface 821. The first surface 811 and the second surface 821 are both flat and fit. By making the first surface 811 and the second surface 821 both flat and fit, the tightness between the first heat sink 81 and the second heat sink 82 is high, reducing the loss of heat transfer efficiency caused by the gap between the copper tube and the radiator, which is conducive to further improving the heat dissipation effect of the heat sink 8.

[0069] refer to Figures 3-8 According to some embodiments of the present utility model, the heat sink 8 has a channel inlet 831 and a channel outlet 832 connected to the heat sink channel 83, and the outdoor unit 100 further includes a heat sink pipe 7, the heat sink pipe 7 includes a first pipe section 71 and a second pipe section 72, the first pipe section 71 is connected to the channel inlet 831, and the second pipe section 72 is connected to the channel outlet 832. For example, during the operation of the outdoor unit 100, the heat exchange medium enters the heat sink channel 83 from the first pipe section 71 through the channel inlet 831, and fully exchanges heat between the heat exchange medium and the heat sink 8 in the heat sink channel 83, and then flows out through the channel outlet 832 and enters the second pipe section 72. By setting up the heat dissipation pipe 7, and connecting the first pipe section 71 of the heat dissipation pipe 7 with the flow channel inlet 831, and connecting the second pipe section 72 with the flow channel outlet 832, it is convenient for the heat exchange medium to flow in and out through the heat dissipation pipe 7, so that the heat exchange medium can take away the heat on the heat dissipation plate 8 by flowing between the heat dissipation flow channel 83 and the heat dissipation pipe 7, thereby realizing the heat dissipation of the electronic control module 42 by the heat dissipation plate 8.

[0070] Optionally, the heat dissipation pipe 7 is an aluminum part; optionally, the heat dissipation plate 8 is an aluminum part.

[0071] refer to Figures 3-8 According to some optional embodiments of the present invention, the heat dissipation pipe 7 is connected to the heat dissipation plate 8 by welding. By welding the heat dissipation pipe 7 and the heat dissipation plate 8, the heat dissipation pipe 7 can be stably fixed on the heat dissipation plate 8, which is conducive to improving the connection stability of the heat dissipation pipe 7 and the heat dissipation plate 8, and the connection relationship formed by welding does not have a gap or crack, so that leakage of the heat exchange medium at the connection between the heat dissipation pipe 7 and the heat dissipation plate 8 can be avoided.

[0072] refer to Figures 1-8, according to some alternative embodiments of the present utility model, a part of the pipeline of the refrigerant circulation system of the outdoor unit 100 constitutes a heat dissipation pipe 7. For example, during the operation of the outdoor unit 100, the refrigerant enters the heat dissipation flow channel 83 through the flow channel inlet 831 from the first pipe section 71, and the refrigerant exchanges heat fully with the heat dissipation plate 8 in the heat dissipation flow channel 83, then flows out through the flow channel outlet 832 and enters the second pipe section 72, and re-enters the refrigerant circulation system via the second pipe section 72. By making a part of the pipeline of the refrigerant circulation system of the outdoor unit 100 constitute the heat dissipation pipe 7, the refrigerant can be used as a heat exchange medium to effectively exchange heat with the electronic control module 42 through the heat dissipation pipe 7, and the heat dissipation pipe 7 and the heat exchange medium do not need to be provided separately.

[0073] Reference Figures 1-3 , according to some alternative embodiments of the present utility model, the electronic control box component 4 further includes a box body 41, the electronic control module 42 and the heat dissipation plate 8 are arranged in the box body 41, the box body 41 has an air flow inlet 411 and an air flow outlet 412, the air flow inlet 411 is communicated with the external space of the outdoor unit 100, and the air flow outlet 412 is communicated with the fan cavity 12. During the operation of the outdoor unit 100, the operation of the outdoor fan causes a pressure difference between the inside of the fan cavity 12 and the external space of the outdoor unit 100, so that the air flow in the external space can enter through the air flow inlet 411 of the box body 41 under the action of this pressure difference, and flows through the electronic control module 42 in the box body 41 to exchange heat fully with the electronic control module 42 to realize heat dissipation of the electronic control module 42, and then the air flow can flow out of the box body 41 through the air flow outlet 412 and enter the fan cavity 12.

[0074] During the operation of the outdoor unit 100, the air flow temperature inside the outdoor unit housing 1 is relatively high. If the air flow inside the outdoor unit housing 1 is used to dissipate heat from the electronic control module 42 of the electronic control box component 4, the heat dissipation effect is poor. In this way, by providing the air flow inlet 411 communicated with the external space of the outdoor unit 100 and the air flow outlet 412 communicated with the fan cavity 12, the air flow in the external space enters the box body 41 to dissipate heat from the electronic control module 42, which is beneficial to improving the heat dissipation effect of the electronic control module 42, reducing or avoiding the electronic control box component 4 being in a high-temperature working condition, reducing or avoiding the adverse impact on the operation of the outdoor unit 100 caused by the electronic control box component 4 being in a high-temperature working condition, and further reducing or avoiding the adverse impact on the air conditioning capacity of the air conditioning equipment.

[0075] For example, when the outdoor unit 100 is applied to a variable-frequency air conditioning equipment, by dissipating heat from the electronic control module 42 through the air flow in the external space of the outdoor unit housing 1 to improve the heat dissipation effect, it can effectively avoid the outdoor unit 100 from self-limiting frequency protection due to the heat generation of the electronic control box component 4 under high-temperature working conditions, so that the air conditioning equipment can achieve a good air conditioning effect.

[0076] Reference Figures 1-3, according to some alternative embodiments of the present utility model, the outdoor housing 1 is formed with an air inlet 16, the air inlet 16 is located on the side wall of the compressor chamber 13, and the air inlet 16 communicates the air flow inlet 411 with the external space of the outdoor unit 100. By forming the air inlet 16 on the outdoor housing 1 that communicates the air flow inlet 411 and the external space, it is convenient for the air flow in the external space to smoothly enter the box body 41 through the air inlet 16 and the air flow inlet 411; by making the air inlet 16 located on the side wall of the compressor chamber 13, the distance between the air inlet 16 and the fan chamber 12 is relatively far, which is conducive to reducing the influence of the air flow flowing out of the fan chamber 12 on the temperature of the air flow at the air inlet 16, and is conducive to the air flow entering the box body 41 through the air inlet 16 to effectively dissipate heat from the electronic control module 42.

[0077] Reference Figures 1-3 , according to some alternative embodiments of the present utility model, an air intake space 5 is defined between the electronic control box component 4 and the side wall of the compressor, and the air intake space 5 communicates the air inlet 16 with the air flow inlet 411. By defining the air intake space 5 that communicates the air inlet 16 and the air flow inlet 411 between the electronic control box component 4 and the side wall of the compressor, so that the air flow can smoothly enter the box body 41 through the air flow inlet 411 to dissipate heat from the electronic control module 42.

[0078] During the operation of the outdoor unit 100, the operation of the outdoor fan causes a pressure difference between the inside of the fan chamber 12 and the external space of the outdoor unit 100, so that the air flow in the external space enters the outdoor housing 1 through the air inlet 16 under the action of this pressure difference, then flows towards the air flow inlet 411 through the air intake space 5 and can enter the box body 41 through the air flow inlet 411 of the box body 41, and flows through the electronic control module 42 in the box body 41 to fully exchange heat with the electronic control module 42 to achieve heat dissipation of the electronic control module 42. Then, the air flow can flow out of the box body 41 through the air flow outlet 412 and enter the fan chamber 12.

[0079] Reference Figures 1-3 , according to some alternative embodiments of the present utility model, in the left - right direction, the air inlet 16 is located on the side of the compressor chamber 13 away from the fan chamber 12. By making the air inlet 16 located on the side of the compressor chamber 13 away from the fan chamber 12 in the left - right direction, the distance between the air inlet 16 and the fan chamber 12 is relatively far, which is conducive to reducing the influence of the air flow flowing out of the fan chamber 12 on the temperature of the air flow at the air inlet 16, and is conducive to the air flow entering the box body 41 through the air inlet 16 to effectively dissipate heat from the electronic control module 42.

[0080] Reference Figures 1-3, according to some alternative embodiments of the present utility model, at least a part of the air inlet 411 is opposite to the air intake 16 in the left - right direction.
