Description

Technical Field

[0002] With the development of air conditioning technology, air conditioning equipment is being used in increasingly wider areas and in increasingly harsher environments. The electrical components inside the air conditioner's electrical box generate a large amount of heat. Excessive temperature can reduce the lifespan of these components, decrease operating efficiency, and even burn them out. Therefore, to ensure the stable operation of the air conditioner's electrical box, it is necessary to cool the internal components, thus ensuring reliable operation. Currently, electrical boxes cannot be completely sealed to ensure heat dissipation. When the equipment is in extreme environments, such as near the sea or in high-humidity areas, moisture and salt from the air can enter the electrical box, causing the components to rust and corrode, affecting the reliability of the electrical box.

[0023] The beneficial effects of this utility model are as follows:

[0024] (1) A heat dissipation channel is formed by setting waterproof and breathable components and air valve components at the air inlet and outlet of the housing, respectively. The heat dissipation channel can be opened and closed by simply opening and closing the air valve components. When the electrical box is in working condition, the air valve components are opened, and the air enters the electrical box after being filtered by the waterproof and breathable components, which takes away the heat inside the electrical box.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] With the development of air conditioning technology, air conditioning equipment is being used in increasingly wider fields and in increasingly harsh environments. The electrical components inside the air conditioner's electrical box generate a lot of heat during operation. Excessive temperature can reduce the lifespan of these components, decrease their operating efficiency, or even burn them out. Therefore, to ensure the stable operation of the air conditioner's electrical box, it is necessary to cool down the internal components, thereby ensuring the air conditioner's reliable operation.

[0039] To ensure heat dissipation, existing electrical boxes cannot be completely sealed. When placed in extreme environments, such as near the sea or in places with high humidity, moisture and salt in the air will enter the electrical box, causing the electrical components to rust and corrode, thus affecting the reliability of the electrical box.

[0040] Based on this, this application provides a sealed electrical box. In operation, the heat dissipation channel can be closed to dissipate heat from the electrical components inside the box, thereby improving the stability of the electrical box's operation. In non-operation, the heat dissipation channel is closed to prevent moisture and corrosive substances such as salt and alkali in the air from entering the electrical box, thereby improving the service life of the electrical box.

[0041] Please see Figure 1-5 This application provides a sealed electrical box, including: a housing 10, a waterproof and breathable component 20, and an air valve assembly 30. The housing 10 is used to install electrical components. The waterproof and breathable component 20 is located at one end of the housing 10 and can filter out moisture in the air. When the electrical box 100 is in operation, the electrical components generate heat. External cold air enters the housing 10 through the waterproof and breathable component 20 and exchanges heat with the hot air inside the housing 10 to dissipate heat and cool the electrical components inside the housing 10. The air valve assembly 30 is closedly located at the end of the housing 10 away from the waterproof and breathable component 20, forming a heat dissipation channel with the waterproof and breathable component 20. External airflow can enter the housing 10 through the waterproof and breathable component 20 and then be ejected through the air valve assembly 30. Specifically, when the electrical box 100 is in operation, the air valve assembly 30 is in the open state. At this time, the heat dissipation channel is open, and external cold air can enter the heat dissipation channel through the waterproof and breathable assembly 20. After heat exchange inside the heat dissipation channel, the hot air is discharged through the air valve assembly 30. When the electrical box 100 is not in operation, the air valve assembly 30 is closed. At this time, the heat dissipation channel is closed, and external air cannot enter the interior of the housing 10. Therefore, moisture and impurities such as salt and alkali in the air cannot enter the interior of the housing 10, thereby improving the service life of the electrical components inside the housing 10 and improving the stability of the electrical box 100.

[0042] Compared to traditional electrical boxes with air inlets and outlets, the sealed electrical box 100 provided in this embodiment, in the working state, generates a large amount of heat from the internal electrical components, requiring heat dissipation and cooling. At this time, the heat dissipation channel is open, allowing airflow to enter and dissipate heat from the internal electrical components, thereby improving their lifespan. Simultaneously, the air inlet end of the electrical box 100 is equipped with a waterproof and breathable component 20 to block moisture and other substances in the external air, preventing damage to the electrical components. In the non-working state, the internal electrical components of the electrical box 100 do not generate heat and have no heat dissipation requirement. One end of the heat dissipation channel is closed, and the air pressure inside the shell 10 is constant. External airflow cannot enter the shell 10 through the waterproof and breathable component 20, thus preventing damage and corrosion to the internal electrical components of the electrical box 100 in harsh environments.

[0043] Please see Figure 1 and Figure 2 Furthermore, in some embodiments, the housing 10 includes a mounting box 11 for mounting electrical components and a sealing cover 12. The mounting box 11 is provided with a mounting groove, the electrical components are mounted inside the mounting box 11, and the sealing cover 12 is provided to seal the opening of the mounting groove.

[0044] Preferably, the housing 10 is rectangular, with the waterproof and breathable component 20 and the air valve component 30 respectively disposed at both ends in the length direction to form a long strip heat dissipation channel, which can reduce airflow turbulence, increase airflow velocity, and thus improve heat dissipation efficiency.

[0045] Furthermore, in some embodiments, the housing 10 is provided with an air inlet, and the waterproof and breathable component 20 is disposed at the air inlet. The waterproof and breathable component 20 is provided with a locking sleeve 21 and a waterproof and breathable element 22. The outer wall of the locking sleeve 21 is provided with a groove 212. By inserting the outer periphery of the air inlet into the groove 212, the locking sleeve 21 is sealed and locked at the air inlet. The waterproof and breathable element 22 is fixed on the locking sleeve 21 and fixed at the air inlet by the locking sleeve 21 to filter the airflow entering the housing 10. Specifically, the waterproof and breathable element 22 is a waterproof and breathable membrane or a waterproof and breathable mesh, which can not only filter moisture in the air, but also prevent mosquitoes from entering the housing 10. In this embodiment, the air inlet is disposed on the mounting box 11 to facilitate molding and to maintain the aesthetic appearance of the electrical box 100.

[0046] Please see Figure 2 and Figure 3Furthermore, in some embodiments, the locking sleeve 21 is provided with an air inlet 211, and the waterproof and breathable component 22 is embedded in the locking sleeve 21, located downstream of the airflow path where the air inlet 211 is located. That is, external airflow enters the interior of the locking sleeve 21 through the air inlet 211, is filtered by the waterproof and breathable component 22, and then enters the interior of the housing 10 for heat exchange. Preferably, the air inlet 211 is located on the side wall of the locking sleeve 21, protruding from the housing 10 and located outside the housing 10. This can prevent water droplets from splashing directly onto the waterproof and breathable component 22, further improving the waterproof performance of the waterproof and breathable component 20. External cold air enters the locking sleeve 21 through the air inlet 211, and then is filtered by the waterproof and breathable component 22 before entering the interior of the housing 10.

[0047] Please see Figure 2 Furthermore, in some embodiments, the housing 10 is provided with an air outlet, and the air valve assembly 30 is located at the air outlet. The air valve assembly 30 includes an air valve 31 and a fan 32. The air valve 31 is sealed at the air outlet; the fan 32 is located close to the air valve 31 and is used to draw the hot airflow inside the housing 10 to the outside of the housing 10, thereby creating a negative pressure inside the housing 10. External cold air is drawn into the housing 10 through the air inlet, thereby achieving heat exchange. In this embodiment, the fan 32 is located outside the air valve 31, downstream of the airflow path of the air valve 31.

[0048] Please see Figure 2 and Figure 4 Furthermore, in some embodiments, the housing 10 also has a wire-passing hole for passing wires through, and a waterproof wire-protecting sleeve 40 is provided at the wire-passing hole to seal the wire-passing hole. Specifically, the waterproof wire-protecting sleeve 40 is inserted into the wire-passing hole, and a soft plug 41 is provided inside the waterproof wire-protecting sleeve 40 to cover the wire. During the process of locking the waterproof wire-protecting sleeve 40, the soft plug 41 is squeezed and deformed to achieve a seal. Furthermore, the soft plug 41 has a through hole 414 along its length for threading wires, and its side wall has a cut 413 to facilitate threading wires and adapt to wires of different diameters. At the same time, the two ends of the soft plug 41 along its length are a large-diameter end 411 and a small-diameter end 412, respectively. The diameter of the large-diameter end 411 is larger than the diameter of the small-diameter end 412. The large-diameter end 411 is located on the side of the waterproof wire-protecting sleeve 40 inside the housing 10 and is locked with a locking switch. In this embodiment, the soft plug 41 is a rubber plug with good deformation capacity. When the rubber plug is inserted into the waterproof cable sleeve 40, if the cable still has a degree of freedom, the rubber plug can be squeezed and deformed by adjusting the locking switch of the waterproof cable sleeve 40, thereby achieving a seal.

[0049] Please see Figure 2 and Figure 5Furthermore, in some embodiments, the electrical box 100 also includes a high-heat drive board 51 and several low-heat drive boards 52 for integrating electrical components, wherein the heat generated by the high-heat drive board 51 is greater than the heat generated by the low-heat drive boards 52. It is understood that the high-heat drive board 51 is the main drive board, and the low-heat drive boards 52 are control main boards and filter boards, etc., which will not be described in detail here.

[0050] Furthermore, in some embodiments, the high-heat drive plate 51 is installed inside the housing 10 close to the waterproof and breathable component 20. This allows external cold air entering from the waterproof and breathable component 20 to quickly exchange heat with the high-heat drive plate 51, carrying away its heat and cooling it down. Specifically, the high-heat drive plate 51 is fixed to the bottom of the mounting groove, and the waterproof and breathable component 20 is also installed at the bottom of the mounting groove, located below and behind the high-heat drive plate 51. The air valve assembly 30 is located on the side wall of the mounting groove away from the waterproof and breathable component 20. In this configuration, the fan 32 draws air, causing external air to blow upwards through the waterproof and breathable component 20 into the housing in a direction perpendicular to the bottom of the mounting groove. The airflow carries away the heat from the high-heat drive plate 51 from bottom to top, dissipating its heat, and then the airflow is deflected and blown out towards the air valve assembly 30. This allows the external airflow to have greater contact with the high-heat drive plate 51, improving the heat exchange efficiency between the external airflow and the heat drive plate 51. It also avoids the external airflow being directly discharged through the inner wall of the mounting slot and the sealing cover plate 12, and avoids the problem of low heat exchange efficiency caused by insufficient airflow through the high-heat drive plate 51 when the air volume is insufficient.

[0051] The low-heat drive plate 52 is installed inside the housing 10, located between the high-heat drive plate 51 and the air valve assembly 30. The heat generated by the low-heat drive plate 52 is carried away by the airflow entering the housing 10, thereby cooling it and improving the service life of the electrical components.

[0052] Furthermore, in some embodiments, the high-heat drive plate 51 is also provided with a heat dissipation structure 511, which directly contacts the high-heat drive plate 51 for heat conduction, thereby rapidly cooling the high-heat drive plate 51. Mounting holes are provided at the bottom of the mounting box 11 corresponding to the position of the high-heat drive plate 51, for sealing and embedding the heat dissipation structure 511, so that the heat dissipation structure 511 partially or completely protrudes from the bottom of the mounting box 11 through the mounting holes.

[0053] Specifically, in some embodiments, the heat dissipation structure 511 is a refrigerant heat dissipation structure, which is connected to an external refrigerant flow path and provides cooling directly to the high-heat drive plate 51 through the refrigerant. In this configuration, the refrigerant heat dissipation structure 511 can remove most of the heat generated by the high-heat drive plate 51, resulting in high heat dissipation efficiency.

[0054] Furthermore, the external refrigerant flow path includes a heat exchanger and a throttling valve. The refrigerant heat dissipation structure 511 is located between the refrigerant outlet of the heat exchanger and the throttling valve. In this way, whether in heating or cooling mode, the refrigerant temperature of the refrigerant heat dissipation structure 511 is moderate, which can remove most of the heat dissipated by the high-heat drive plate 51.

[0055] In some other embodiments, the heat dissipation structure 511 can be a thermoelectric cooler. The cold end of the thermoelectric cooler is directly thermally connected to the high-heat drive board 51. The cooling capacity generated by the cold end directly cools the high-heat drive board 51. The cooling capacity of the thermoelectric cooler can be adjusted according to the current. When the power of the high-heat drive board 51 is large, it generates more heat and has a greater heat dissipation requirement. In this case, the thermoelectric cooler will increase its drive current to generate more cooling capacity to cool the high-heat drive board 51. This will not be described in detail here.

[0056] Please see Figure 5 This application also provides an air conditioner, including a sealed electrical box 100 and a refrigerant flow path 200, which includes a heat exchanger and a throttling valve. In some embodiments, the high-heat drive plate 51 in the sealed electrical box 100 is cooled by a refrigerant heat dissipation structure 511, which uses refrigerant in the refrigerant flow path 200 to cool the high-heat drive plate 51. Preferably, the refrigerant heat dissipation structure 511 is located between the refrigerant outlet of the heat exchanger and the throttling valve. In this configuration, regardless of whether the air conditioner is in heating or cooling mode, the refrigerant temperature of the refrigerant heat dissipation structure 511 is moderate, which can effectively cool and dissipate heat from the high-heat drive plate 51, thereby improving the stability of the sealed electrical box 100.

[0057] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows:

[0058] (1) A heat dissipation channel is formed by setting waterproof and breathable components and air valve components at the air inlet and outlet of the housing, respectively. The heat dissipation channel can be opened and closed by simply opening and closing the air valve components. When the electrical box is in working condition, the air valve components are opened, and the air enters the electrical box after being filtered by the waterproof and breathable components, which takes away the heat inside the electrical box. When the electrical box is not in working condition, the air valve components are closed, so that the electrical box housing is kept sealed and external air cannot enter, thus ensuring that the electrical box is dry and free from salt and alkali damage, thereby improving the stability of the internal components of the electrical box.

[0059] (2) By placing the high heat drive plate with the largest heat generation close to the waterproof and breathable component, and placing the waterproof and breathable component and the high heat drive plate at the bottom of the mounting groove, and placing the air valve component on the side wall of the mounting groove away from the waterproof and breathable component, the cold air entering the electrical box through the waterproof and breathable component has a larger heat exchange area with the high heat drive plate, which is conducive to the cold air and the high heat drive plate to quickly exchange heat and dissipate heat, thereby improving the heat dissipation efficiency of the high heat drive plate.

[0060] (3) A refrigerant heat dissipation structure is used to quickly cool down the high-heat drive board in order to further ensure the stability and service life of the electrical box;

[0061] (4) By setting the refrigerant heat dissipation structure between the refrigerant outlet and the throttling valve of the heat exchanger, it is ensured that the refrigerant heat dissipation structure can effectively cool and dissipate heat from the high-heat drive plate regardless of whether the air conditioner is in heating or cooling mode.

[0062] 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 utility model patent. 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 this utility model also intends to include these modifications and variations.
