[0033] Figures 1 to 6 The condenser 100 provided by the present invention is shown. As can be seen from the figure, the present invention provides a condenser 100, which includes a condenser main body 110 and a liquid outlet unit 120; the condenser main body 110 has a liquid cooling channel 111 for the liquid cooling working medium to flow, and the liquid cooling working medium is used to exchange heat with the condenser main body 110 to dissipate heat; the liquid cooling channel 111 has a channel inlet 1101 and a channel outlet 1102; the liquid outlet unit 120 has an inner cavity, at least one liquid inlet 1201 and a liquid outlet 1220; the liquid inlet 1201 is communicated with the liquid outlet 1220 through the inner cavity; the channel outlet 1102 is communicated with the liquid inlet 1201; the liquid outlet 1220 is arranged facing the condenser main body 110. For example, the liquid outlet 1220 may be arranged facing the fins on the condenser main body 110.

[0034] The condenser 100 of the present invention innovatively integrates the liquid outlet unit 120 and the condenser main body 110, and this breakthrough design greatly enhances the heat dissipation performance. Specifically, the liquid-cooling working medium circulates in the liquid-cooling channel 111 of the condenser main body 110. After efficiently exchanging heat with the condenser main body 110, it seamlessly connects to the liquid inlet 1201 of the liquid outlet unit 120, and this connection benefits from the carefully designed channel structure. The internal structure of the liquid outlet unit 120 promotes the smooth transmission of the liquid-cooling working medium until it is directly sprayed onto the surface of the condenser main body 110 from the liquid outlet 1220. By using the direct spraying effect of the liquid-cooling working medium, the heat conduction process is strongly enhanced, and the heat exchange speed per unit area is significantly increased. That is to say, the present invention is a two-stage heat dissipation, which is particularly effective for the problem of high-temperature heat accumulation in the fin-dense area, and fundamentally solves the problem of low heat dissipation efficiency caused by high fin temperature.

[0035] Compared with the traditional fin widening method, the present invention achieves a significant improvement in heat exchange efficiency on the premise of good cost control. It cleverly combines the two mechanisms of liquid-cooling heat conduction and spray evaporation, which not only optimizes the heat exchange efficiency, but also ensures the efficient operation of the system and the energy efficiency ratio, provides an effective solution for dealing with high heat loads, and at the same time avoids excessive increase in cost and structural complexity.

[0036] In a feasible embodiment, as Figure 4 and Figure 5 shown, the liquid-cooling channel 111 may include a first sub-channel 1110, a second sub-channel 1120, and a third sub-channel 1130 that extend along the length direction of the condenser main body 110; the first sub-channel 1110 is located at the upper part of the condenser main body 110, and the first sub-channel 1110 has a first sub-channel inlet and a first sub-channel outlet; the second sub-channel 1120 is located at the lower part of the condenser main body 110, and the second sub-channel 1120 has a second sub-channel inlet and a second sub-channel outlet; the third sub-channel 1130 is located in the middle of the condenser main body 110, and the third sub-channel 1130 has a third sub-channel inlet and a third sub-channel outlet; the third sub-channel inlet is set as the channel inlet 1101; the third sub-channel outlet communicates with the first sub-channel inlet and the second sub-channel inlet; the liquid-cooling channel 111 has a plurality of channel outlets 1102, which are respectively a first channel outlet 1021 and a second channel outlet 1022; the first sub-channel outlet is set as the first channel outlet 1021; the second sub-channel outlet is set as the second channel outlet 1022.

[0037] In specific implementation, the liquid cooling channels 111 of the condenser 100 are divided into three independent sub-channels, namely the first sub-channel 1110, the second sub-channel 1120, and the middle third sub-channel 1130; the third sub-channel 1130 serves as the core inlet channel, located in the middle of the condenser body 110, and receives the liquid cooling working medium from the outside. Its inlet directly serves as the total inlet of the entire liquid cooling channel 111, ensuring the starting point of uniform distribution of the working medium; the outlet of the third sub-channel 1130 has a unique design. It is not only connected to the inlet of the first sub-channel but also connected to the inlet of the second sub-channel, that is, it realizes flow splitting. The first sub-channel 1110 and the second sub-channel 1120 are respectively located in the upper and lower parts of the condenser body 110, each having independent inlets and outlets. The design of the three independent sub-channels can cover the heat load areas at different heights of the condenser body 110. Through such a multi-level channel design, the condenser 100 can more effectively distribute the liquid cooling working medium according to the specific heat exchange requirements of different regions, accelerating the heat transfer process and balancing the overall temperature distribution, thus significantly improving the heat dissipation performance and the energy efficiency of the system.

[0038] In this embodiment, there are multiple liquid inlet ports 1201, namely the first liquid inlet port 1211 and the second liquid inlet port 1212; the outlet of the first sub-channel is connected to the first liquid inlet port 1211; the outlet of the second sub-channel is connected to the second liquid inlet port 1212; one three-way joint can be set at the outlet of the third sub-channel. The three-way joint has a first port, a second port, and a third port. The first port is connected to the outlet of the third sub-channel, the second port is connected to the inlet of the first sub-channel through the first return pipe, and the third port is connected to the inlet of the second sub-channel through the second return pipe.

[0039] According to an embodiment of the present invention, the liquid outlet unit 120 includes a spray pipe 121 and a connecting pipe 122; the spray pipe 121 is arranged on the condenser body 110. The side wall of the spray pipe 121 has a communication port 1210, and the first liquid inlet port 1211 and the liquid outlet port 1220 are arranged on the spray pipe 121; one end of the connecting pipe 122 is communicated with the communication port 1210, and the second liquid inlet port 1212 is arranged at the other end of the connecting pipe 122; wherein, the interiors of the spray pipe 121 and the connecting pipe 122 are defined as inner cavities.

[0040] In specific implementation, the liquid cooling working medium flowing out of the second sub-channel 1120 can smoothly enter the spray pipe 121 through the connecting pipe 122 to participate in the next round of heat exchange process. The internal spaces of the spray pipe 121 and the connecting pipe 122 are defined as a common "inner cavity", which means that the liquid cooling working medium entering through either the first liquid inlet port 1211 of the spray pipe 121 or the second liquid inlet port 1212 of the connecting pipe 122 will circulate in a continuous and closed system. This design helps to maintain the stability of the internal pressure of the system and is also convenient for controlling the flow rate of the liquid cooling working medium and the spraying effect.

[0041] In this embodiment, a one-way valve leading outward may be provided at the outlet of the first sub-channel.

[0042] According to an embodiment of the present invention, it further includes a first controller, a first temperature sensor 130, a second temperature sensor 140, a first control valve 150, and a second control valve 160; the first controller is connected to the first temperature sensor 130, the second temperature sensor 140, the first control valve 150, and the second control valve 160; the first temperature sensor 130 is disposed on the upper part of the condenser main body 110; the first control valve 150 is disposed in the first sub-channel 1110; the second temperature sensor 140 is disposed on the lower part of the condenser main body 110; the second control valve 160 is disposed in the second sub-channel 1120; wherein, the first controller is configured to open the first control valve 150 when the first temperature sensor 130 detects that the temperature of the upper part of the condenser main body 110 is higher than a preset value; the first controller is configured to open the second control valve 160 when the second temperature sensor 140 detects that the temperature of the lower part of the condenser main body 110 is higher than a preset value.

[0043] During specific implementation, the first controller is introduced as the core, responsible for receiving signals from the first temperature sensor 130 and the second temperature sensor 140, and controlling the actions of the first control valve 150 and the second control valve 160 accordingly. This design allows the condenser 100 to autonomously adjust according to real-time temperature changes, improving the response speed and efficiency of the system. The first temperature sensor 130 is deployed on the upper part of the condenser main body 110 to monitor the temperature changes in this area; the second temperature sensor 140 is located at the lower part and is responsible for monitoring the temperature of the lower area. Such a layout ensures an accurate grasp of the overall temperature distribution of the condenser 100. The first control valve 150 is installed inside the first sub-channel 1110, and the second control valve 160 is located in the second sub-channel 1120. Based on the temperature condition of the upper area, when the first controller detects that the temperature exceeds the preset threshold, it will activate the first control valve 150 to adjust the flow rate of the liquid cooling working medium in the upper channel to enhance heat dissipation. Similarly, if the temperature of the lower area is too high, the second control valve 160 will be opened to increase the liquid cooling working medium circulation in the lower channel to effectively manage the local heat load. Vice versa, to reduce the liquid consumption.

[0044] It can be understood that the first controller may have three states. The first state is that the first control valve 150 and the second control valve 160 are opened simultaneously to dissipate heat from the upper area and the lower area at the same time; the second state is that the first control valve 150 is opened to dissipate heat from the upper area; the third state is that the second control valve 160 is opened to dissipate heat from the lower area.

[0045] According to an embodiment of the present invention, it further includes a third control valve 170. The third control valve 170 has a liquid inlet end and a liquid outlet end, and the liquid outlet end is arranged at the channel inlet 1101.

[0046] During specific implementation, the user can choose to open or close the control valve according to actual needs to save liquid usage.

[0047] According to an embodiment of the present invention, it further includes a third temperature sensor 180 and a second controller. The third temperature sensor 180 is arranged on the middle part of the condenser body 110 for detecting the temperature of the condenser body 110. The second controller is connected to the third temperature sensor 180 and the third control valve 170, and is used to open the third control valve 170 when the third temperature sensor 180 detects that the temperature of the condenser body 110 is higher than a preset value.

[0048] During specific implementation, the third temperature sensor 180 is arranged on the condenser body 110. Its purpose is to monitor the average or key part temperature of the entire condenser body 110, provide comprehensive temperature feedback information, reduce the number of temperature sensors to lower costs, and at the same time facilitate the user to choose whether to use the liquid cooling and heat dissipation of the present invention.

[0049] In another feasible embodiment, not shown in the figure, the liquid cooling channel 111 includes a first sub-channel 1110, a second sub-channel 1120, and a third sub-channel 1130. The first sub-channel 1110 is located at the upper part of the condenser body 110, and the first sub-channel 1110 has a first sub-channel inlet and a first sub-channel outlet. The second sub-channel 1120 is located at the lower part of the condenser body 110, and the second sub-channel 1120 has a second sub-channel inlet and a second sub-channel outlet. The third sub-channel 1130 is located at the middle part of the condenser body 110, and the third sub-channel 1130 has a third sub-channel inlet and a third sub-channel outlet. The third sub-channel inlet communicates with the first sub-channel outlet and the third sub-channel outlet. The third sub-channel outlet is set as the channel outlet 1102. There are multiple channel inlets 1101, which are respectively a first channel inlet 1101 and a second channel inlet 1101. The first sub-channel inlet is set as the first channel inlet 1101. The second sub-channel inlet is set as the second channel inlet 1101.

[0050] In specific implementation, the liquid cooling channel 111 of the condenser 100 is divided into three sub-channels, namely the first sub-channel 1110 located in the upper part, the second sub-channel 1120 located in the lower part, and the third sub-channel 1130 located in the middle part. The intention of such a design is to more meticulously manage the heat exchange process in different regions through segmented processing in the vertical direction. The third sub-channel 1130 plays a bridging role in terms of structure. Its inlet is connected to both the outlet of the first sub-channel 1110 and its own (the third sub-channel 1130) outlet, while the outlet of the third sub-channel 1130 is set as the total outlet of the entire liquid cooling channel 111. Such a design may be intended to achieve the recycling and optimization of the heat flow, especially the redistribution of heat in the upper-middle region. Different from the previous description, the diversity of the inlet of the liquid cooling channel 111 is clarified here. There are two independent inlets, namely the inlet of the first sub-channel as the first channel inlet 1101, and the inlet of the second sub-channel as the second channel inlet 1101. This design facilitates the distribution of the liquid cooling working medium from different sources or as needed, enhancing the adaptability of the system to changes in the heat load.

[0051] According to an embodiment of the present invention, the liquid outlet 1220 is arranged towards the upper part of the condenser main body 110.

[0052] In specific implementation, the liquid outlet 1220 is deliberately arranged towards the upper part of the condenser main body 110. This design takes into account the principle of hot air rising and natural convection when the condenser 100 is working. By directly spraying the liquid working medium upwards, the hot air flow can be more effectively utilized to promote the rapid vaporization of the liquid droplets and heat absorption. Moreover, arranging the liquid outlet 1220 towards the upper part aims to strengthen the heat exchange process by utilizing the natural convection formed by the rising hot air, enabling the sprayed liquid working medium to more quickly cover and cool high-temperature areas such as the fins, especially the part where heat is prone to accumulate in the upper part of the condenser 100. This not only improves the heat dissipation rate but also helps to maintain the uniformity of the temperature inside the condenser 100, reduce thermal stress, and extend the service life of the equipment.

[0053] The present invention also provides an outdoor unit of an air conditioner, including: an outdoor unit housing 200; the condenser 100 as described in the above embodiment, which is arranged inside the outdoor unit housing 200. The specific structure, working principle, and beneficial effects of the condenser 100 are the same as those in the above embodiment and will not be elaborated here.

[0054] According to an embodiment of the present invention, it further includes an outdoor fan, which is arranged inside the outdoor unit housing 200.

[0055] In specific implementation, a multi-stage liquid cooling channel 111 is constructed inside the condenser main body 110, enabling the liquid cooling working medium to circulate in the liquid cooling channel 111, effectively exchanging heat with the condenser main body 110. Subsequently, the liquid cooling working medium after heat exchange is directly guided to the liquid outlet unit 120 through the channel outlet 1102, making full use of the liquid cooling working medium (such as water) to achieve evaporation heat dissipation. At the same time, under the action of the outdoor unit fan, this heat dissipation process can be accelerated.

[0056] The present invention also provides an air conditioner, including: the condenser 100 as described in the above embodiment; or, the outdoor unit of the air conditioner as described in the above embodiment. The specific structure, working principle, and beneficial effects of the condenser 100 are the same as those in the above embodiment, and will not be elaborated here.
