Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to an outdoor unit for an air conditioner. Background Technology

[0002] The air conditioner's control box contains circuit boards that control various components of the air conditioner, as well as electrical components such as reactors. These electrical components generate a lot of heat during operation. Due to the large amount of heat generated, the components may overheat and malfunction. Therefore, it is necessary to cool the components in a timely manner to ensure their normal operation.

[0003] Currently, the main heat dissipation method for electrical control boxes is to utilize the airflow from the outdoor unit's fan to remove the heat generated by the electrical components. Specifically, the control box is equipped with air inlets and outlets. The air inlet allows outside air to enter the control box, and the outlet carries the heat out. However, this heat dissipation method easily allows moisture and dust from the external environment to enter the control box, affecting the normal operation of the electrical components. This is especially true in high-humidity environments, which can easily lead to malfunctions and damage to the electrical components. Utility Model Content

[0004] Based on this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide an outdoor unit for an air conditioner that can effectively dissipate heat inside the electrical control box while ensuring the sealing of the power supply box and effectively preventing dust and water.

[0005] To achieve the above objectives, this utility model provides an outdoor unit for an air conditioner, comprising:

[0006] The outdoor unit itself has a heat dissipation airflow duct;

[0007] An electrical control box is located inside the outdoor unit body. The electrical control box includes a box body, a refrigeration mechanism located inside the box body, and an electrical control main board located on the side wall inside the box body. The refrigeration mechanism has an air supply vent and an air return vent. The refrigeration mechanism is used to deliver cold air from the air supply vent and recover hot air from the air return vent.

[0008] The heat dissipation module is located on the outer side of the side wall of the housing where the electronic control motherboard is located, and is situated on the heat dissipation duct.

[0009] As one implementation, a refrigeration cycle system is also included, which is located inside the outdoor unit body, and the refrigeration mechanism is connected to the refrigeration cycle system.

[0010] In one embodiment, the interior of the housing is provided with an air supply duct, and the air outlet is disposed on the air supply duct; the refrigeration mechanism includes a return air duct, a refrigeration unit disposed in the return air duct, and a guide fan, the return air outlet is disposed in the return air duct, and the guide fan is located between the air supply duct and the return air duct.

[0011] In one embodiment, the refrigeration mechanism is located at the bottom of the housing, and an L-shaped air duct is provided inside the housing. The L-shaped air duct, together with the inner side wall and the inner top wall of the housing, forms the air supply duct. The air outlet is provided on the side wall and top of the L-shaped air duct. The main control board is located in the area enclosed by the air supply duct and the return air duct.

[0012] In one embodiment, the outdoor unit has an air inlet and an air outlet that connect to the heat dissipation duct. A main body fan is installed in the heat dissipation duct. The main body fan is used to draw in outside air from the air inlet into the heat dissipation duct and to blow the gas in the heat dissipation duct out to the outside from the air outlet.

[0013] In one embodiment, an air guide shroud is connected to the outer side of the side wall of the housing where the electronic control motherboard is located. The two ends of the air guide shroud are respectively connected to the air inlet and the air outlet, and the heat dissipation module is disposed in the air guide shroud.

[0014] In one embodiment, the two ends of the air guide cover are respectively flared openings.

[0015] In one implementation, the heat dissipation module consists of multiple heat sinks.

[0016] In one embodiment, the box is a hollow structure with an opening on one side, and a box cover is detachably installed on the opening side of the box.

[0017] Therefore, according to the embodiment of this utility model, the outdoor unit of the air conditioner encloses the heat-generating electronic control main board inside the casing, and connects the heat dissipation module to the side wall of the casing where the electronic control main board is located. This allows part of the heat generated by the electronic control main board to be transferred to the heat dissipation module. In this way, the airflow is fully guided by the air guide shroud of the outdoor unit's main fan, allowing the airflow to pass through the heat dissipation module and carry away the heat. At the same time, a closed space is formed inside the casing. A refrigeration mechanism is set inside the casing, and through the clever design of the air supply duct, the guide fan draws the cold air cooled by the refrigeration unit in the return air duct into the supply air duct, and blows the cold air out towards the electronic control main board through the supply air duct. The heat generated by the electrical components on the electronic control main board is reduced by the cold air, and the hot air is recovered from the return air vent. After being cooled again by the refrigeration unit, the cold air is sent out again by the guide fan. This forms a heat dissipation cycle inside the casing, effectively reducing the temperature inside the casing. At the same time, due to the closed design of the casing, dust and moisture can be effectively prevented from entering the casing, thereby avoiding damage to the electrical components on the electronic control main board.

[0018] In other words, compared with traditional technology, the outdoor unit of the air conditioner in this embodiment of the utility model designs the heat dissipation method of the electrical control box as internal circulation cooling and external cold air flow cooling, which can not only achieve effective heat dissipation inside the electrical control box, but also ensure the sealing of the power box and effectively prevent dust and water.

It should be understood that the described embodiments are merely some embodiments of this utility model, and not all embodiments.

[0029] In related technologies, the control box of an air conditioner houses circuit boards and electrical components such as reactors that control various parts of the air conditioner. These electrical components generate a significant amount of heat during operation. This high heat generation can cause overheating and malfunction, necessitating timely cooling to ensure proper functioning. Currently, the control box primarily utilizes the outdoor unit's fan to dissipate the heat generated by the components. Specifically, the control box has air inlets and outlets. The inlet allows outside air to enter the control box, while the outlet carries the heat away. However, this cooling method is susceptible to contamination from external elements like moisture and dust entering the control box, affecting the normal operation of the components, especially in high-humidity environments where damage is more likely.

[0030] Therefore, this utility model embodiment provides an outdoor unit for an air conditioner. The outdoor unit for an air conditioner according to this utility model embodiment can achieve effective heat dissipation inside the electrical control box, while ensuring the sealing of the power supply box, effectively preventing dust and water damage.

[0031] Please see Figures 1 to 5 This utility model embodiment provides an outdoor unit for an air conditioner, comprising:

[0032] The outdoor unit body 10 has a heat dissipation duct 12;

[0033] An electrical control box 20 is located inside the outdoor unit body 10. The electrical control box 20 includes a housing 21, a refrigeration mechanism located inside the housing 21, and an electrical control main board 22 located on the side wall inside the housing 21. The refrigeration mechanism has an air supply port 25 and a return air port 26. The refrigeration mechanism is used to deliver cold air from the air supply port 25 and recover hot air from the return air port 26.

[0034] The heat dissipation module 14 is located on the outer side of the side wall of the housing 21 where the electronic control motherboard is located, and is situated on the heat dissipation duct 12.

[0035] Furthermore, the outdoor unit of the air conditioner in this embodiment of the present invention also includes a refrigeration circulation system 13, which is disposed inside the outdoor unit body 10, and the refrigeration mechanism is connected to the refrigeration circulation system 13.

[0036] In this embodiment of the invention, the outdoor unit body 10 has an air inlet and an air outlet communicating with the heat dissipation duct 12. A main body fan 11 is installed in the heat dissipation duct 12, which draws in outside air from the air inlet into the heat dissipation duct 12 and blows the air out of the duct 12 through the air outlet. To improve airflow efficiency, a guide shroud 15 is connected to the outer side of the side wall of the housing 21 where the electronic control motherboard 22 is located. The two ends of the guide shroud 15 are respectively connected to the air inlet and the air outlet, and the heat dissipation module 14 is disposed within the guide shroud 15.

[0037] Optionally, in some embodiments of this utility model, the two ends of the air guide shroud 15 are respectively flared openings; in this way, the flared openings allow airflow to enter the air guide shroud 15 more efficiently and flow fully through the heat dissipation module 14, thereby quickly removing the heat from the heat dissipation module 14. Furthermore, the heat dissipation module 14 can be composed of multiple heat sinks, utilizing the principle of heat conduction to transfer the heat generated on the electronic control motherboard 22 to the heat sinks after passing through the side wall of the housing 21.

[0038] In this embodiment of the present invention, the housing 21 is provided with an air supply duct 23, and the air outlet 25 is disposed on the air supply duct 23; the refrigeration mechanism includes a return air duct 24, a refrigeration unit 27 disposed in the return air duct 24, and a guide fan 28, the return air outlet 26 is disposed in the return air duct 24, and the guide fan 28 is located between the air supply duct 23 and the return air duct 24.

[0039] In some embodiments of this invention, to improve heat dissipation within the housing 21, the cooling mechanism is located at the bottom of the housing 21. An L-shaped air duct is installed inside the housing 21, forming an air supply duct 23 together with the inner sidewall and top wall of the housing 21. Air outlets 25 are located on the sidewall and top of the L-shaped air duct. The main control board 22 is located within the area enclosed by the air supply duct 23 and the return air duct 24. This allows the heat-generating electrical components on the main control board 22 to be positioned close to the air outlets 25 on the sidewall and top of the L-shaped air duct, enabling the cool air to remove more heat.

[0040] In addition, for ease of installation, in some embodiments of this utility model, the box 21 is a hollow structure with an opening on one side, and a box cover 29 is detachably installed on the opening side of the box 21.

[0041] Therefore, according to the embodiment of the present invention, the outdoor unit of the air conditioner encloses the heat-generating electronic control main board 22 inside the housing 21, and connects the heat dissipation module to the side wall of the housing 21 where the electronic control main board 22 is located. This allows part of the heat generated by the electronic control main board 22 to be transferred to the heat dissipation module 14. In this way, the airflow is fully directed by the main fan 11 on the outdoor unit body 10 through the air guide shroud 15, allowing the airflow to pass through the heat dissipation module 14 and carry away the heat. At the same time, a closed space is formed inside the housing 21, and a refrigeration mechanism is set inside the housing 21. Through the ingenious design of the air supply duct 23, the guide fan 28 directs the return airflow. The cold air cooled by the cooling unit 27 in channel 24 is drawn into the air supply duct 23 and blown out towards the main control board 22. The heat generated by the electrical components on the main control board 22 is reduced by the cold air, and the hot air is recovered from the return air vent 26. After being cooled again by the cooling unit 27, the cold air is sent out again by the guide fan 28. This forms a heat dissipation cycle inside the cabinet 21, effectively reducing the temperature inside the cabinet 21. At the same time, due to the closed design of the cabinet 21, it can effectively prevent dust and moisture from entering the interior of the cabinet 21, thereby avoiding the impact on the electrical components on the main control board 22.

[0042] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the outdoor unit of the air conditioner. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
