Description

Technical Field

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

[0002] The outdoor unit is a crucial component of an air conditioner. It is primarily installed on the exterior of a building and connected to the indoor unit via pipes, working together to perform cooling or heating functions. The electrical components within the outdoor unit control its operation. To ensure their long-term and stable operation, these components are typically housed in a control box, which is equipped with a heat dissipation structure. Currently, the control box and heat dissipation structure are cooled by airflow. This involves placing the heat dissipation structure within the first chamber of the outdoor unit, drawing air from the outdoor heat exchanger towards the structure to cool the electrical components inside the control box. However, when outdoor temperatures are high, the airflow blowing towards the heat dissipation structure is itself high, failing to effectively reduce its temperature. This can easily lead to overheating of the electrical components inside the control box, causing the unit to shut down or even burn out, thus increasing the failure rate of the outdoor unit. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an outdoor unit that helps reduce the failure rate of outdoor units.

[0004] This utility model also proposes an air conditioner having the above-mentioned outdoor unit.

[0005] An outdoor unit according to a first aspect of the present invention includes a housing; an electrical control box disposed within the housing; a heat dissipation structure connected to the electrical control box, the heat dissipation structure being used to reduce the temperature of the inner cavity of the electrical control box; and a condenser pipe with its outlet disposed within the housing, the condenser pipe being used to supply condensate flow, the outlet of the condenser pipe being located above the heat dissipation structure, the condensate in the condenser pipe being able to drip onto the heat dissipation structure, thereby reducing the temperature of the heat dissipation structure and the inner cavity of the electrical control box.

[0006] It has at least the following beneficial effects:

[0007] The condensate drain outlet is located above the heat dissipation structure. Therefore, after the air conditioner is started, the condensate in the condensate drain outlet can pass through and drip onto the heat dissipation structure. Because the condensate is at a low temperature, the dripping condensate on the heat dissipation structure quickly lowers its temperature. When the temperature of the heat dissipation structure drops rapidly, it absorbs heat from the inner cavity of the control box through heat conduction, thereby rapidly reducing the temperature of the electrical components inside the control box. This prevents the components from overheating and shutting down or even burning out when the outdoor temperature is high, ensuring that the outdoor unit can operate stably for a long time, thus reducing the failure rate of the outdoor unit.

[0008] According to the first aspect of the present invention, the outdoor unit of the heat dissipation structure includes multiple fins, which are distributed along the vertical direction.

[0009] According to the first aspect of the present invention, the outdoor unit has drainage holes on multiple fins, and the multiple drainage holes are used for condensate to flow through, so that the condensate can flow from top to bottom through the surface of the multiple fins and reduce the temperature of the multiple fins.

[0011] According to the first aspect of the present invention, the projections of any two adjacent drainage holes in the vertical direction are a first circular projection and a second circular projection, respectively, and the first circular projection and the second circular projection do not coincide.

[0012] According to the first aspect of the present invention, the projections of the inner bottom walls of the multiple water storage tanks in the vertical direction are all overlapping rectangular projections.

[0015] The outdoor unit according to the first aspect of the present invention further includes an outdoor fan and a compressor, wherein the outdoor fan is disposed in the first chamber and the compressor is disposed in the second chamber.

[0034] refer to Figure 1 and Figure 2 The outdoor unit according to the first aspect of the present invention includes a housing 100, an electrical control box 300, a heat dissipation structure 200, and a condenser pipe 140.

[0035] The electrical control box 300 is located inside the housing 100. The heat dissipation structure 200 is connected to the electrical control box 300 and is used to reduce the temperature inside the electrical control box 300. The condenser pipe 140 is located inside the housing 100 and is used to supply condensate. The outlet of the condenser pipe 140 is located above the heat dissipation structure 200. The condensate in the condenser pipe 140 can drip onto the heat dissipation structure 200, thereby reducing the temperature of the heat dissipation structure 200 and the internal temperature of the electrical control box 300.

[0036] The control box 300, heat dissipation structure 200, and condenser pipe 140 are all connected inside the housing 100. In the first aspect of this utility model, the outdoor unit also includes various electrical components for controlling the operation of the outdoor unit, all of which are installed in the control box 300. When the electrical components inside the control box 300 start working, they generate a large amount of heat. This heat is transferred through the control box 300 to the heat dissipation structure 200, and then, utilizing the heat dissipation characteristics of the heat dissipation structure 200, the heat can be quickly dissipated into the air, allowing the heat inside the control box 300 to be quickly transferred to the outside, thereby reducing the temperature inside the control box 300. As an embodiment of the first aspect of this utility model, the heat dissipation structure 200 can be a heat spreader.

[0037] Condensation is mainly generated during the cooling process of the indoor unit. When the indoor unit operates in cooling mode, the surface temperature of its internal heat exchanger drops. When this temperature is lower than the dew point temperature of the indoor air, water vapor in the air condenses on the surface of the heat exchanger, forming liquid water, i.e., condensate. This condensate drips into the water collection tray in the indoor unit. In the first aspect of this utility model, the outlet of the condenser pipe 140 is located inside the casing 100 of the outdoor unit, and the inlet of the condenser pipe 140 is connected to the water collection tray, allowing the condensate in the water collection tray to flow into the condenser pipe 140.

[0038] Understandably, the outlet of the condenser pipe 140 is located above the heat dissipation structure 200. Therefore, after the air conditioner is started, the condensate in the condenser pipe 140 can pass through the outlet and drip onto the heat dissipation structure 200. Because the condensate is at a low temperature, the condensate dripping onto the heat dissipation structure 200 can quickly lower its temperature. When the temperature of the heat dissipation structure 200 drops rapidly, it absorbs heat from the inner cavity of the control box 300 through heat conduction, thereby rapidly reducing the temperature of the electrical components inside the control box 300. This prevents the electrical components from shutting down or even burning out due to overheating when the outdoor temperature is high, ensuring that the outdoor unit can operate stably for a long time, thus reducing the failure rate of the outdoor unit.

[0039] refer to Figure 1 and Figure 2 The heat dissipation structure 200 includes multiple fins 210, which are distributed in a vertical direction. Each of the multiple fins 210 is provided with a drain hole 220, which is used to allow condensate to pass through, so that the condensate can flow from top to bottom through the surface of the multiple fins 210 and reduce the temperature of the multiple fins 210.

[0040] Understandably, the multiple fins 210 are all made of a metal material with good thermal conductivity. The multiple fins 210 are all connected to the electrical control box 300. Through the thermal conductivity of the fins 210, the heat generated by the electrical components inside the electrical control box 300 is rapidly conducted to the multiple fins 210. Because the multiple fins 210 have a large surface area, they can more effectively disperse and transfer heat to the surrounding environment, reducing the overall temperature inside the electrical control box 300, and consequently lowering the temperature of the electrical components inside the electrical control box 300.

[0041] In the first aspect of this invention, each of the multiple fins 210 is provided with a drain hole 220. Condensate dripping from the outlet of the condenser tube 140 first drips onto the uppermost fin 210. When the condensate on the uppermost fin 210 accumulates to a certain extent, it flows across it. The flowing condensate can pass through the drain hole 220 on the uppermost fin 210 and flow to the lower fins 210, and so on. This allows the condensate dripping from the condenser tube 140 to flow sequentially from top to bottom across the surfaces of the multiple fins 210, thereby absorbing heat from the multiple fins 210 and achieving the purpose of rapidly cooling them.

[0042] refer to Figure 2 Multiple fins 210 each have a water storage tank 230, which is used to hold condensate. Multiple drain holes 220 are respectively provided on the inner bottom wall of the multiple water storage tanks 230. It can be understood that the condensate dripping from the drain holes 220 and the outlet of the condenser tube 140 can fall into the water storage tank 230, which can hold a certain amount of condensate. On the one hand, when the condensate flow rate in the condenser tube 140 is large, the water storage effect of the water storage tank 230 can prevent condensate from overflowing from the fins 210, so that the condensate can be fully utilized. That is, the drain holes 220 also serve as overflow holes. On the other hand, the inner wall of the water storage tank 230 increases the surface area of ​​the fins 210, increasing the contact area between the condensate and the fins 210. This not only improves the heat dissipation effect of the fins 210, but also improves the heat exchange effect between the condensate and the fins 210, enabling the condensate to absorb more heat from the fins 210 per unit time and increasing the cooling speed of multiple fins 210.

[0043] refer to Figure 2 and Figure 4The projections of any two adjacent drain holes 220 in the vertical direction are respectively a first circular projection 221 and a second circular projection 222, and the first circular projection 221 and the second circular projection 222 do not coincide. In the first aspect embodiment of this utility model, the drain holes 220 on the two spaced-apart fins 210 are coaxial, and the projections of any two adjacent drain holes 220 in the vertical direction are both circular projections, defined as the first circular projection 221 and the second circular projection 222. It can be understood that when the condensate in the water storage tank 230 reaches a certain amount, the condensate in the water storage tank 230 will pass through the drain holes 220 on the bottom wall of the water storage tank 230 and drip into the water storage tank 230 on the lower fin 210. Since the first circular projection 221 and the second circular projection 222 do not overlap, the dripping condensate cannot continuously pass through two or more drain holes 220. Therefore, the condensate must first drip into the water storage tank 230 before it can continue to drip down into the water storage tank 230 on the next fin 210. This ensures that the condensate can be fully utilized and that it can make full contact with multiple fins 210.

[0044] refer to Figure 2 and Figure 4 In one embodiment of the first aspect of this utility model, the projections of the inner bottom walls of the plurality of water storage tanks 230 in the vertical direction are all overlapping rectangular projections 231. The rectangular projection 231 has four corners, and the sides of the first circular projection 221 and the second circular projection 222 are tangent to the two sides forming opposite corners, respectively. It can be understood that the projections of any two adjacent drain holes 220 in the vertical direction are the first circular projection 221 and the second circular projection 222, respectively, and the projection of the inner bottom wall of the water storage tank 230 in the vertical direction is the rectangular projection 231.

[0045] The edges of the first circular projection 221 and the second circular projection 222 are tangent to the two edges of the two opposite corners, respectively. Specifically, the first circular projection 221 is tangent to the two edges of one corner, and the second circular projection 222 is tangent to the two edges of the other corner, forming an opposite angle. This ensures that the first and second circular projections are closest to the two opposite corners of the rectangular projection 231. In other words, when the edges of the first and second circular projections 221 are tangent to the two edges of the two opposite corners, the horizontal distance between any two adjacent drain holes 220 is maximized. This allows condensate to spread sufficiently on the fins 210, ensuring adequate contact between the condensate and the fins. Consequently, the condensate absorbs more heat from the fins 210, improving the cooling effect of multiple fins 210.

[0046] refer to Figure 1 , Figure 3 and Figure 5 A drain pipe 150 is provided on the bottom wall of the housing 100. The drain pipe 150 is used to drain condensate on the inner bottom wall of the housing 100 to the outside of the housing 100. It can be understood that the inner cavity of the housing 100 is connected to the external environment through the drain pipe 150. Condensate on the lowermost fin 210 can pass through the drain hole 220 and drip onto the inner bottom wall of the housing 100, and then the condensate on the inner bottom wall of the housing 100 is drained to the outside of the housing 100 through the drain pipe 150. As an embodiment of the first aspect of this utility model, the indoor unit also includes a guide pipe, which is disposed inside the housing 100. The upper end of the guide pipe is connected to the drain hole 220 on the lowermost fin 210, and the lower end of the guide pipe is connected to the drain pipe 150.

[0047] refer to Figure 1 and Figure 5 The outdoor unit also includes a partition 110, which is located inside the housing 100 and connected to it. The partition 110 divides the inner cavity of the housing 100 into a first chamber 120 and a second chamber 130. The electrical control box 300 and the heat dissipation structure 200 are both connected to the partition 110, and the heat dissipation structure 200 is located inside the first chamber 120. The outdoor unit also includes an outdoor fan 400 and a compressor 500. The outdoor fan 400 is located inside the first chamber 120, and the compressor 500 is located inside the second chamber 130. It can be understood that the partition 110 divides the inner cavity of the housing 100 into the first chamber 120 and the second chamber 130, the outdoor fan 400 is installed in the first chamber 120, and the compressor 500 is installed in the second chamber 130. Both the electrical control box 300 and the heat dissipation structure 200 are connected to the partition 110. The electrical control box 300 is located in the second chamber 130, and the heat dissipation structure 200 is located in the first chamber 120. After the outdoor fan 400 is started, airflow is generated in the first chamber 120. The airflow acts on the heat dissipation structure 200, allowing it to carry away some of the heat, thus further improving the heat dissipation effect of the heat dissipation structure 200.

[0048] An air conditioner according to a second aspect embodiment of the present invention includes an outdoor unit. The air conditioner also includes an indoor unit and an expansion valve, forming a refrigerant flow circuit between the outdoor unit, the indoor unit, and the expansion valve, thereby completing the air conditioner's cooling and heating functions. The indoor unit, compressor 500, expansion valve, and outdoor fan 400 are common components of air conditioners and will not be described further here. The air conditioner possesses all the beneficial effects brought by the aforementioned outdoor unit, which will not be described further here.
