[0076] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0077] In the description of this utility model, it should be understood that the terms "lower," "inner," "outer," "circumferential," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0078] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0079] The following is for reference. Figures 1-8 Description of an anti-condensation device 100 according to an embodiment of the present utility model.

[0080] Reference Figure 1According to an embodiment of the present utility model, the anti-condensation device 100 includes: a housing 110, a vent valve 130, and a heat exchange component. The vent valve 130 is disposed in the housing 110 and communicates with the internal space of the housing 110. The heat exchange component exchanges heat with the vent valve 130.

[0081] For example, the housing 110 can serve as a mounting carrier for the vent valve 130 to facilitate its installation. The vent valve 130 is used to balance the internal and external air pressure difference of the anti-condensate water device 100. For instance, when the pressure inside the housing 110 is greater than the pressure of the external environment, the gas inside the housing 110 can be discharged through the vent valve 130. When the pressure inside the housing 110 is less than the pressure of the external environment, the gas (e.g., air) in the external environment can enter the housing 110 through the vent valve 130. This achieves the pressure balancing function of the vent valve 130.

[0082] Furthermore, the vent valve 130 exchanges heat with the heat exchange assembly.

[0083] For example, the heat exchange assembly is filled with a heat exchange medium, which can be used to exchange heat with the heating component of the anti-condensation device 100. For example, when the temperature of the heating component of the anti-condensation device 100 is too high, the heat exchange assembly can cool to reduce the temperature of the heating component of the anti-condensation device 100; when the temperature of the heating component of the anti-condensation device 100 is too low, the heat exchange assembly can heat to increase the temperature of the heating component of the anti-condensation device 100. At the same time, the heat of the heat exchange medium can be transferred to the vent valve 130 to exchange heat with the vent valve 130.

[0084] When the heat exchange component is in the cooling state, the heat exchange component can absorb heat from the vent valve 130 to reduce the temperature of the vent valve 130. The water vapor carried by the gas in the external environment before entering the box 110 through the vent valve 130 can be condensed to reduce the humidity of the gas entering the box 110.

[0085] When the heat exchange component is in heating mode, it can heat the vent valve 130 to increase its temperature. The water vapor carried by the gas in the external environment before entering the housing 110 through the vent valve 130 can be heated and evaporated to reduce the humidity of the gas entering the housing 110.

[0086] Therefore, by exchanging heat between the heat exchange component and the vent valve 130, the humidity of the gas entering the housing 110 through the vent valve 130 is reduced, which helps to reduce the risk of corrosion of the internal components of the anti-condensation device 100, and also helps to reduce the risk of short circuits in the anti-condensation device 100, thus increasing the service life of the anti-condensation device 100. In addition, by exchanging heat between the vent valve 130 and the heat exchange component, there is no need to set up additional components for heat exchange of the vent valve 130 on the anti-condensation device 100, which helps to simplify the structure of the anti-condensation device 100, increase the space for other components on the anti-condensation device 100, and improve the ease of production and assembly of the anti-condensation device 100, while also helping to reduce the production cost of the anti-condensation device 100.

[0087] The heat exchange between the heat exchange component and the vent valve 130 can be direct or indirect. For example, the heat exchange component can exchange heat with the vent valve 130 through the housing 110; or the heat exchange component can directly contact the vent valve 130 for heat exchange.

[0088] In related technologies, in order to reduce the humidity of the gas entering the anti-condensation equipment through the vent valve, it is usually necessary to set up a separate cooling device for the vent valve so that the water vapor carried by the gas will condense before entering the anti-condensation equipment. However, setting up an additional cooling device will make the structure of the anti-condensation equipment more complex and the production cost higher. In addition, the additional cooling device will occupy the space of the anti-condensation equipment used for assembling heating components and reduce the capacity of the anti-condensation equipment.

[0089] This application enables the vent valve 130 to exchange heat with a heat exchange component, which can cool or heat the vent valve 130. Before the gas in the external environment enters the housing 110 through the vent valve 130, the water vapor carried by the gas can condense or evaporate, thereby reducing the humidity of the gas entering the housing 110. This eliminates the need for additional components on the anti-condensation device 100 for heat exchange with the vent valve 130, which simplifies the structure of the anti-condensation device 100, increases the space available for arranging other components, improves the ease of production and assembly of the anti-condensation device 100, and reduces the production cost of the anti-condensation device 100.

[0090] Combination Figures 1 to 3 as well as Figure 9 In some embodiments of this utility model, the anti-condensation device 100 is provided with a gas channel 132, and the vent valve 130 is provided with a vent membrane, or the vent valve 130 is provided with a vent membrane and a gas channel 132. After the gas passes through the gas channel 132, it enters the vent membrane, and the gas channel 132 exchanges heat with the heat exchange component.

[0091] In some examples, combined Figures 1 to 3 as well as Figure 9 The anti-condensation device 100 is provided with a gas channel 132. The gas channel 132 can be located on the outside of the internal space of the housing 110 away from the breathable membrane. When the pressure inside the housing 110 is low, gas from the external environment can enter the gas channel 132. The gas channel 132 exchanges heat with the heat exchange components to lower or raise the temperature of the gas channel 132. The gas channel 132 can further transfer heat to the gas entering it, so that at least part of the water vapor carried by the gas entering the gas channel 132 can condense or evaporate within the gas channel 132.

[0092] After the gas flows through the gas channel 132, it can further flow through the breathable membrane. Since the water vapor carried by the gas has condensed or evaporated during the process of flowing through the gas channel 132, the humidity of the gas flowing to the breathable membrane can be effectively reduced. The breathable membrane can block liquid water to prevent the condensate in the gas channel 132 from entering the internal space of the chamber 110 through the breathable membrane. At the same time, the breathable membrane can also prevent the water vapor carried by the gas from entering the internal space of the chamber 110, which is conducive to further reducing the humidity of the gas entering the internal space of the chamber 110.

[0093] In other examples, the vent valve 130 is provided with a vent membrane and a gas channel 132. Gas from the external environment enters the internal space of the housing 110 through the gas channel 132 and the vent membrane in sequence. The gas channel 132 exchanges heat with the heat exchange components to lower or raise the temperature of the gas channel 132. The gas channel 132 can further transfer heat to the gas entering it, so that at least some of the water vapor carried by the gas entering the gas channel 132 can condense or evaporate within the gas channel 132.

[0094] After the gas flows through the gas channel 132, it can further flow through the breathable membrane. Since the water vapor carried by the gas has condensed or evaporated during the process of flowing through the gas channel 132, the humidity of the gas flowing to the breathable membrane can be effectively reduced. The breathable membrane can block liquid water to prevent the condensate in the gas channel 132 from entering the internal space of the chamber 110 through the breathable membrane. At the same time, the breathable membrane can also prevent the water vapor carried by the gas from entering the internal space of the chamber 110, which is conducive to further reducing the humidity of the gas entering the internal space of the chamber 110.

[0095] It is understandable that the specific location of the gas channel 132 can be determined according to actual production requirements, and no specific limitation is made here.

[0096] Combination Figures 1 to 3 as well as Figure 9In some embodiments of this utility model, the anti-condensation device 100 is provided with a gas channel 132, and the vent valve 130 is provided with a vent membrane, or the vent valve 130 is provided with a vent membrane and a gas channel 132, the vent membrane is located in the gas channel 132, and the gas channel 132 exchanges heat with the heat exchange component.

[0097] In some examples, combined Figures 1 to 3 as well as Figure 9 The anti-condensation device 100 is provided with a gas channel 132, and a breathable membrane is provided inside the gas channel 132. The gas channel 132 exchanges heat with the heat exchange components to lower or raise the temperature of the gas channel 132. When gas from the external environment enters the gas channel 132, the gas channel 132 can transfer heat to the gas entering it, so that at least part of the water vapor carried by the gas entering the gas channel 132 can condense or evaporate inside the gas channel 132.

[0098] As the gas flows through the gas channel 132, it can also pass through the breathable membrane. The breathable membrane can also prevent the water vapor carried by the gas from entering the internal space of the chamber 110, which helps to further reduce the humidity of the gas entering the internal space of the chamber 110. At the same time, the breathable membrane can block liquid water to prevent condensate in the gas channel 132 from entering the internal space of the chamber 110 through the breathable membrane.

[0099] In other examples, the vent valve 130 is provided with a vent membrane and a gas passage 132, which exchanges heat with a heat exchange component to lower or raise the temperature of the gas passage 132. When gas from the external environment enters the gas passage 132, the gas passage 132 can transfer heat to the gas entering it, so that at least some of the water vapor carried by the gas entering the gas passage 132 can condense or evaporate within the gas passage 132.

[0100] During the process of gas passing through gas channel 132, the gas flows through the breathable membrane. The breathable membrane can also prevent the water vapor carried by the gas from entering the internal space of the chamber 110, which helps to further reduce the humidity of the gas entering the internal space of the chamber 110. At the same time, the breathable membrane can block liquid water to prevent condensate in gas channel 132 from entering the internal space of the chamber 110 through the breathable membrane.

[0101] By placing the breathable membrane inside the gas channel 132, the gas channel 132 can protect the breathable membrane, which helps to reduce the risk of damage to the breathable membrane.

[0102] Combination Figures 1 to 3 as well as Figure 9In some embodiments of this utility model, the heat exchange assembly includes a connecting joint 120, which exchanges heat with the vent valve 130.

[0103] For example, the heat exchange medium can be transported to the heat exchange assembly through the connecting joint 120, so that the heat exchange assembly can exchange heat with the heating component of the anti-condensation device 100, which is beneficial to improving the working performance of the heating component of the anti-condensation device 100. The heat exchange medium in the heat exchange assembly can also be discharged from the heat exchange assembly through the connecting joint 120, so as to facilitate the replacement of the heat exchange medium and the maintenance of the heat exchange assembly.

[0104] When the heat exchange medium flows through the connecting joint 120, the heat of the heat exchange medium can be transferred to the vent valve 130, so that the vent valve 130 can exchange heat with the connecting joint 120. Before the gas in the external environment enters the box 110 through the vent valve 130, the water vapor carried by the gas can be condensed or evaporated to reduce the humidity of the gas entering the box 110.

[0105] Optionally, the heat exchange between the vent valve 130 and the connecting joint 120 can be direct or indirect. The specific heat exchange method can be determined according to actual production requirements and is not specifically limited here.

[0106] Combination Figures 1 to 3 In some embodiments of this utility model, the vent valve 130 is provided with a vent membrane and a gas channel 132, or the anti-condensation device 100 is provided with a gas channel 132, the vent valve 130 is provided with a vent membrane, and the gas channel 132 exchanges heat with the connecting joint 120.

[0107] For example, gas from the external environment can enter the internal space of the housing 110 through the gas channel 132 and the breathable membrane. By exchanging heat between the gas channel 132 and the connecting joint 120, the temperature of the gas channel 132 can be reduced or increased. During the process of the gas passing through the gas channel 132, at least some of the water vapor carried by the gas can condense or evaporate within the gas channel 132, thereby reducing the humidity of the gas flowing towards the breathable membrane. The breathable membrane can block liquid water to prevent condensate in the gas channel 132 from entering the internal space of the housing 110 through the breathable membrane. At the same time, the breathable membrane can also prevent water vapor carried by the gas from entering the internal space of the housing 110, which is beneficial to further reduce the humidity of the gas entering the internal space of the housing 110.

[0108] Reference Figure 3 In some embodiments of this utility model, the gas channel 132 is provided with a guide surface 1321 to guide liquid toward the outside of the housing 110.

[0109] For example, the lower part of the inner wall of the gas channel 132 can form a guide surface 1321. The condensate formed by the water vapor carried by the gas can flow along the guide surface 1321 in a direction away from the internal space of the box 110 to guide the condensate out. This helps to reduce the risk of condensate accumulating in the gas channel 132, thereby reducing the risk of condensate entering the internal space of the box 110.

[0110] Reference Figure 3 In some embodiments of the present invention, at least a portion of the inner wall surface of the gas channel 132 extends obliquely to form a guide surface 1321.

[0111] For example, the lower portion of the inner wall of the gas channel 132 can extend outward and downward to form an outward and downward inclined guide surface 1321. The guide surface 1321 can guide the discharge of condensate, which helps to reduce the risk of condensate accumulating in the gas channel 132, thereby reducing the risk of condensate entering the internal space of the housing 110.

[0112] It should be noted that "facing outward" can be understood as facing the direction away from the internal space of the box 110, and "facing downward" can be understood as facing the ground.

[0113] In some examples, the lower and upper portions of the inner wall of the gas channel 132 can extend outward and downward to form a guide surface 1321; in other examples, the entire inner wall of the gas channel 132 can extend outward and downward to form a guide surface 1321. Of course, it is understood that the specific formation method of the guide surface 1321 can be determined according to actual production requirements, and no specific limitation is made here, as long as the guide surface 1321 formed on the inner wall of the gas channel 132 can play the role of draining condensate.

[0114] In some embodiments of this utility model, the angle between the guide surface 1321 and the horizontal plane ranges from 1° to 45°.

[0115] In the above technical solution, by making the angle between the guide surface 1321 and the horizontal plane range from 1° to 45°, it is beneficial to ensure the guiding effect of the guide surface 1321 on the condensate, reduce the risk of condensate accumulating in the airflow channel, and at the same time improve the smoothness of gas flow.

[0116] When the angle between the guide surface 1321 and the horizontal plane is less than 1°, the guide surface 1321 has a poor guiding effect on condensate, and condensate is easy to accumulate in the gas channel 132, and may even cause condensate to enter the internal space of the box 110; when the angle between the guide surface 1321 and the horizontal plane is greater than 45°, the guide surface 1321 is easy to obstruct the flow of gas, making it difficult for gas to flow into the internal space of the box 110.

[0117] In some embodiments of this utility model, the inner wall surface of the gas channel 132 is provided with protrusions and / or grooves.

[0118] For example, the inner wall surface of the gas channel 132 may be provided with a plurality of tiny protrusions, or the inner wall surface of the gas channel 132 may be provided with a plurality of tiny grooves, or the inner wall surface of the gas channel 132 may be provided with a plurality of tiny protrusions and grooves. The tiny protrusions or grooves can increase the roughness of the inner wall surface of the gas channel 132, provide more nucleation sites for water vapor, and help improve the adsorption capacity of the inner wall surface of the gas channel 132 for water vapor, which is conducive to promoting the condensation of water vapor in the gas channel 132, thereby helping to reduce the humidity of the gas entering the chamber 110.

[0119] In some examples, protrusions and / or grooves can be mechanically provided on the inner wall surface of the gas channel 132, for example, by sandblasting to provide protrusions and / or grooves on the inner wall surface of the gas channel 132.

[0120] In other examples, protrusions and / or grooves can be provided on the inner wall of the gas channel 132 by chemical means, for example, protrusions and / or grooves can be provided on the inner wall of the gas channel 132 by chemical corrosion.

[0121] It is understandable that the specific manner in which the inner wall surface of the gas channel 132 is provided with protrusions and / or grooves can be determined according to actual production requirements, and no specific limitation is made here, as long as the roughness of the inner wall surface of the gas channel 132 can be effectively improved.

[0122] In some embodiments of this utility model, the roughness of the inner wall surface of the gas channel 132 can be in the range of 3μm-10μm.

[0123] For example, the roughness of the inner wall surface of the gas channel 132 can be 3μm, 4μm, 5μm or 10μm, etc. By limiting the roughness range of the inner wall surface of the gas channel 132 to 3μm-10μm, it is easier for condensate to adhere to the inner wall of the gas channel 132, and it is also beneficial to reduce the resistance of condensate when flowing along the inner wall surface of the gas channel 132, so as to facilitate the discharge of condensate through the gas channel 132 and reduce the risk of condensate remaining in the gas channel 132.

[0124] In some embodiments of this utility model, a filter screen 140 is provided in the gas channel 132 and / or the opening of the gas channel 132.

[0125] For example, the filter screen 140 can be set in the gas channel 132. When the gas flows into the gas channel 132 and flows towards the vent valve 130, it can pass through the filter screen 140. The water vapor carried by the gas can condense and gather on the filter screen 140, which is beneficial to improve the condensation effect of water vapor and reduce the humidity of the gas entering the internal space of the housing 110. At the same time, the filter screen 140 can filter impurities (such as large dust particles) to prevent the vent valve 130 from being blocked due to the accumulation of impurities on it.

[0126] In some examples, refer to Figure 4 The filter screen 140 can be set at the opening of the gas channel 132. That is, the filter screen 140 can be set at the end of the gas channel 132 away from the internal space of the housing 110. The water vapor carried by the gas can condense at the opening of the gas channel 132, which helps to reduce the risk of condensate entering the gas channel 132. This helps to reduce the risk of condensate entering the gas channel 132 and further flowing into the internal space of the housing 110. At the same time, by setting the filter screen 140 at the opening of the gas channel 132, it helps to reduce the risk of impurities entering the gas channel 132 and clogging the gas channel 132, thus helping to ensure the smooth flow of gas.

[0127] In some examples, filters 140 can be installed both inside the gas channel 132 and at its opening. This helps to further improve the effect of water vapor condensation, reduce the risk of condensate entering the gas channel 132, and thus reduce the risk of condensate entering the gas channel 132 further flowing into the internal space of the housing 110. At the same time, it helps to further reduce the risk of impurities clogging the gas channel 132 and the vent valve 130, thereby ensuring smooth gas flow.

[0128] It is understandable that the specific location of the filter 140 can be determined according to actual production requirements, and no specific limitation is made here.

[0129] like Figure 5 As shown, in some embodiments of the present invention, the filter screen 140 includes a mounting ring 141 and a screen body 142. The mounting ring 141 is provided on the outer periphery of the screen body 142, and the mounting ring 141 is detachably mounted to the inner wall of the gas channel 132.

[0130] For example, the mounting ring 141 can serve as a mounting carrier for the mesh body 142, providing support for the mesh body 142 and facilitating its installation. The mounting ring 141 can be detachably installed onto the inner wall of the gas channel 132, thereby enabling the filter screen 140 to be detachably assembled with the inner wall of the gas channel 132. This improves the ease of assembly of the filter screen 140 and facilitates its disassembly.

[0131] In some embodiments of this utility model, the mounting ring 141 and the gas channel 132 are threaded together.

[0132] For example, the surface of the mounting ring 141 opposite to the inner wall of the gas channel 132 is machined with a threaded structure, and the inner wall of the gas channel 132 is also machined with a threaded structure, so that the mounting ring 141 can be threadedly engaged with the inner wall of the gas channel 132. When assembling the filter screen 140 with the gas channel 132, the filter screen 140 can be screwed into the gas channel 132, so that the mounting ring 141 and the inner wall of the gas channel 132 are detachably connected, which helps to improve the ease of disassembly and assembly of the filter screen 140.

[0133] In other embodiments, the inner wall of the gas channel 132 may be provided with a snap-fit ​​structure, and the mounting ring 141 may be detachably installed to the inner wall of the gas channel 132 through the snap-fit ​​structure; or the mounting ring 141 may also be detachably installed to the inner wall of the gas channel 132 by adhesive bonding. It is understood that the specific assembly method between the mounting ring 141 and the inner wall of the gas channel 132 can be determined according to actual production requirements, and is not specifically limited here, as long as the mounting ring 141 is detachably installed to the inner wall of the gas channel 132.

[0134] In some embodiments of this utility model, the vent valve 130 exchanges heat with the heat exchange assembly through a heat-conducting element.

[0135] In some examples, the heat-conducting component can be configured as a thermally conductive adhesive, and the vent valve 130 can exchange heat with the heat exchange component through the thermally conductive adhesive to improve the heat exchange effect between the heat exchange component and the vent valve 130, thereby improving the effect of water vapor evaporation or condensation into condensate, and further reducing the humidity of the gas entering the internal space of the housing 110.

[0136] In other examples, the housing 110 can be configured as a heat-conducting component, and the vent valve 130 can exchange heat with the heat exchange component through the housing 110 to improve the heat exchange effect between the heat exchange component and the vent valve 130. At the same time, no additional components are needed to improve the heat exchange effect, which helps to simplify the structure of the anti-condensate device 100.

[0137] It is understandable that the heat-conducting component can also be configured in other ways. The specific configuration of the heat-conducting component can be determined according to the actual production requirements, and no specific restrictions are made here.

[0138] In some embodiments of this utility model, the heat exchange assembly includes a connecting joint 120 and a heat exchange element connected to the connecting joint 120, and the vent valve 130 is thermally connected to the connecting joint 120 or the heat exchange element through a heat-conducting element.

[0139] For example, the heat exchanger can be configured as a heat exchange plate, and the connecting joint 120 is connected to the heat exchange plate. The heat exchange medium can flow into the heat exchange plate through the connecting joint 120. The heat exchange plate can exchange heat with the heating component of the anti-condensate device 100, and the heat exchange medium in the heat exchange plate can also flow out from the heat exchange plate through the connecting joint.

[0140] In some examples, the vent valve 130 can be installed on the connecting joint 120. The vent valve 130 can exchange heat with the connecting joint 120 through a heat-conducting element. That is, when the heat exchange medium flows into or out of the heat exchange plate through the connecting joint 120, it can transfer heat to the vent valve 130 so that the vent valve 130 can exchange heat with the connecting joint 120 through the heat-conducting element.

[0141] In other examples, the vent valve 130 can be installed on the heat exchanger. The vent valve 130 can exchange heat with the heat exchanger through the heat conduction element. That is, when the heat exchanger exchanges heat with the heating component of the anti-condensate device 100, it can also exchange heat with the vent valve 130.

[0142] It is understandable that the specific components that exchange heat with the vent valve 130 can be determined according to actual production and assembly requirements, and no specific limitations are made here.

[0143] Combination Figures 1 to 3 In some embodiments of this utility model, the heat exchange assembly includes a connecting joint 120 and a heat exchange element communicating with the connecting joint 120, and a vent valve 130 is disposed on the connecting joint 120.

[0144] For example, the heat exchanger can be configured as a heat exchange plate, and the connecting joint 120 is connected to the heat exchange plate. The heat exchange medium can flow into the heat exchange plate through the connecting joint 120. The heat exchange plate can exchange heat with the heating component of the anti-condensate device 100, and the heat exchange medium in the heat exchange plate can also flow out from the heat exchange plate through the connecting joint.

[0145] The vent valve 130 is installed on the connecting joint 120. When the heat exchange medium flows into the heat exchange plate through the connecting joint 120 or flows out of the heat exchange plate, it can transfer heat to the vent valve 130 so as to realize heat exchange between the vent valve 130 and the connecting joint 120.

[0146] By placing the vent valve 130 on the connecting joint 120, it is beneficial to improve the integration of the connecting joint 120 and to prevent the vent valve 130 from encroaching on the space of the heat exchanger, thereby reducing the space available for the heat exchange medium and thus preventing a decrease in the heat exchange effect of the heat exchanger.

[0147] Combination Figures 1 to 3 as well as Figure 6 and Figure 7 In some examples, the vent valve 130 can be integrated with the connector 120, which simplifies the assembly process of the anti-condensation device 100 and improves the production efficiency of the anti-condensation device 100. In other examples, the vent valve 130 and the connector 120 can be separate components, and the vent valve 130 can be installed on the connector 120 to reduce the processing difficulty of the connector 120 and improve the processing efficiency of the connector 120.

[0148] Combination Figures 1 to 3 In some embodiments of this utility model, the connecting joint 120 has an inlet channel 121 and an outlet channel 122.

[0149] For example, the inlet channel 121 and the outlet channel 122 can be connected to an external heat exchange system respectively. The heat exchange medium in the external heat exchange system can enter the cooling element through the inlet channel 121 and exchange heat with the heating component of the anti-condensation device 100. The heat exchange medium in the cooling element can flow into the external heat exchange system through the outlet channel 122 to realize the circulation of the heat exchange medium.

[0150] Combination Figures 1 to 3 In some examples, the vent valve 130 is located between the inlet channel 121 and the outlet channel 122 so that the heat of the heat exchange medium flowing through the inlet channel 121 and the outlet channel 122 can be transferred to the vent valve 130, which is beneficial to improving the heat exchange efficiency of the vent valve 130, thereby improving the efficiency of water vapor carried by the gas to condense into condensate or evaporate.

[0151] In other examples, the vent valve 130 is positioned close to the inlet channel 121. For example, the vent valve 130 may be positioned on the side of the inlet channel 121 away from the outlet channel 122, or the vent valve 130 may be positioned above or below the inlet channel 121. This is beneficial to improving the efficiency of heat transfer from the heat exchange medium flowing through the inlet channel 121 to the vent valve 130, thereby improving the heat exchange efficiency of the vent valve 130.

[0152] In some other examples, the vent valve 130 is positioned close to the outlet channel 122. For example, the vent valve 130 may be positioned on the side of the outlet channel 122 away from the inlet channel 121, or the vent valve 130 may be positioned above or below the outlet channel 122. This is beneficial to improving the efficiency of heat transfer from the heat exchange medium flowing through the outlet channel 122 to the vent valve 130, thereby improving the heat exchange efficiency of the vent valve 130.

[0153] It is understandable that the specific location of the vent valve 130 can be determined according to actual production requirements, and no specific limitation is made here.

[0154] Combination Figures 1 to 3 In some embodiments of this utility model, the vent valve 130 is disposed between the inlet channel 121 and the outlet channel 122. In the arrangement direction of the inlet channel 121, the vent valve 130 and the outlet channel 122, the distance between the vent valve 130 and the inlet channel 121 is 5mm-80mm, and / or the distance between the vent valve 130 and the outlet channel 122 is 5mm-80mm.

[0155] In some examples, the vent valve 130 is located between the inlet channel 121 and the outlet channel 122 so that the heat of the heat exchange medium flowing through the inlet channel 121 and the outlet channel 122 can be transferred to the vent valve 130. The distance between the vent valve 130 and the inlet channel 121 is 5mm-80mm, which improves the efficiency of heat transfer from the heat exchange medium flowing through the inlet channel 121 to the vent valve 130. At the same time, it helps to improve the structural strength of the connecting joint 120 located between the inlet channel 121 and the vent valve 130, and helps to reduce the risk of damage to the inlet channel 121 due to high pressure inside the inlet channel 121.

[0156] In other examples, the distance between the vent valve 130 and the outlet channel 122 is 5mm-80mm to improve the efficiency of heat transfer from the heat exchange medium flowing through the outlet channel 122 to the vent valve 130. This also helps to improve the structural strength of the connection joint 120 located between the outlet channel 122 and the vent valve 130, and helps to reduce the risk of damage to the outlet channel 122 due to high pressure inside the outlet channel 122.

[0157] In some other examples, the distance between the vent valve 130 and the inlet channel 121 is 5mm-80mm, and the distance between the vent valve 130 and the outlet channel 122 is 5mm-80mm, in order to improve the heat exchange efficiency of the heat exchange medium to the vent valve 130 while preventing damage to the inlet channel 121 and the outlet channel 122.

[0158] like Figure 7As shown, in some embodiments of this utility model, the connecting joint 120 is provided with a gas channel 132, and the vent valve 130 is provided in the gas channel 132.

[0159] For example, the gas passage 132 can extend on the connecting joint 120 from the direction away from the internal space of the housing 110 to the direction close to the internal space of the housing 110. The vent valve 130 is disposed in the gas passage 132 so that the vent valve 130 communicates with the internal space of the housing 110, thereby facilitating the flow of gas from the external environment into the internal space of the housing 110 through the vent valve 130, and facilitating the flow of gas in the internal space of the housing 110 out of the housing 110 through the vent valve 130. At least a portion of the gas passage 132 defines the gas passage 132 of the vent valve 130.

[0160] Combination Figures 1 to 3 as well as Figure 7 In some embodiments of this utility model, the connecting joint 120 has an inlet channel 121 and an outlet channel 122, and a gas channel 132 is disposed between the inlet channel 121 and the outlet channel 122, or the gas channel 132 is disposed close to one of the inlet channel 121 and the outlet channel 122.

[0161] In some examples, the gas passage 132 is located between the inlet passage 121 and the outlet passage 122, and the vent valve 130 is located within the gas passage 132. That is, the vent valve 130 is located between the inlet passage 121 and the outlet passage 122 so that the heat of the heat exchange medium flowing through the inlet passage 121 and the outlet passage 122 can be transferred to the vent valve 130, which is beneficial to improving the heat exchange efficiency of the vent valve 130, thereby improving the efficiency of water vapor carried by the gas condensing into condensate or evaporating.

[0162] In other examples, the gas passage 132 is positioned close to the inlet passage 121. For example, the gas passage 132 may be positioned on the side of the inlet passage 121 away from the outlet passage 122, or the gas passage 132 may be positioned above or below the inlet passage 121. A vent valve 130 is provided in the gas passage 132 so that the vent valve 130 is positioned close to the inlet passage 121. This is beneficial to improving the efficiency of heat transfer of the heat exchange medium flowing through the inlet passage 121 to the vent valve 130, thereby improving the heat exchange efficiency of the vent valve 130.

[0163] In some other examples, the gas passage 132 is positioned close to the outlet passage 122. For example, the gas passage 132 may be positioned on the side of the outlet passage 122 away from the inlet passage 121, or the gas passage 132 may be positioned above or below the outlet passage 122. A vent valve 130 is provided in the gas passage 132 so that the vent valve 130 is positioned close to the outlet passage 122. This is beneficial to improving the efficiency of heat transfer of the heat exchange medium flowing through the outlet passage 122 to the vent valve 130, thereby improving the heat exchange efficiency of the vent valve 130.

[0164] In some embodiments of this utility model, the inner wall of the gas channel 132 is provided with a condensation core.

[0165] For example, the heat of the heat exchange medium can be transferred to the gas channel 132 and cool the gas channel 132. When the gas in the external environment flows to the vent valve 130, it can preferentially flow through the gas channel 132. When the gas flows through the gas channel 132, the gas channel 132 can cool the gas so that the water vapor carried by the gas condenses to form condensate. By setting condensation nuclei on the inner wall of the gas channel 132, it is beneficial to improve the efficiency of water vapor condensation to form condensate, thereby further reducing the humidity of the gas entering the internal space of the box 110.

[0166] In some embodiments of this invention, the condensation nucleus is formed as a protrusion and / or a groove.

[0167] For example, the inner wall of the gas channel 132 may be provided with a plurality of tiny protrusions, or the inner wall of the gas channel 132 may be provided with a plurality of tiny grooves, or the inner wall of the gas channel 132 may be provided with a plurality of tiny protrusions and grooves. The tiny protrusions or grooves can increase the roughness of the inner wall of the gas channel 132, provide more nucleation sites for water vapor, and help improve the adsorption capacity of the inner wall of the gas channel 132 for water vapor, which is conducive to promoting the condensation of water vapor in the gas channel 132, thereby helping to reduce the humidity of the gas entering the chamber 110.

[0168] Combination Figure 7 and Figure 9 In some embodiments of this utility model, the connecting joint 120 is provided with a medium flow channel 124 for the flow of heat exchange medium, and the medium flow channel 124 exchanges heat with the gas channel 132.

[0169] For example, the medium flow channel 124 can be arranged adjacent to the gas channel 132. For instance, in the axial direction of the gas channel 132, the gas channel 132 and the medium flow channel 124 can be arranged adjacent to each other; or in the radial direction of the gas channel 132, the gas channel 132 can be arranged around the outer periphery of the medium flow channel 124, or the medium flow channel 124 can be arranged around the outer periphery of the gas channel 132. The medium flow channel 124 carries a heat exchange medium, so that the heat exchange medium entering the medium flow channel 124 can fully contact the gas channel 132, which is beneficial to improving the heat exchange effect between the heat exchange medium and the gas channel 132, thereby improving the heat exchange effect on the gas channel 132 and the vent valve 130, thereby improving the condensation or evaporation effect of water vapor carried by the gas in the gas channel 132, and thus helping to reduce the humidity of the gas entering the internal space of the housing 110.

[0170] Combination Figure 7 and Figure 9 In some embodiments of this utility model, the medium flow channel 124 and the gas channel 132 share at least a portion of their wall surfaces.

[0171] In some instances, the medium flow channel 124 can be formed as an annular channel, and the medium flow channel 124 at least surrounds the radial outer side of the gas channel 132 to facilitate the introduction of heat exchange medium into the medium flow channel 124. After the heat exchange medium flows into the medium flow channel 124, it can fully contact the gas channel 132 to improve the heat exchange effect on the gas channel 132, thereby improving the condensation or evaporation effect of water vapor carried by the gas in the gas channel 132 and reducing the humidity of the gas entering the internal space of the housing 110.

[0172] In some examples, the medium flow channel 124 is fitted over the outside of the gas channel 132. In the axial direction of the gas channel 132, the length of the gas channel 132 is greater than the length of the medium flow channel 124. That is, the medium flow channel 124 and the gas channel 132 share a portion of the wall surface of the gas channel 132. For example, in the axial direction of the gas channel 132, the medium flow channel 124 is arranged around the side of the gas channel 132 near the internal space of the housing 110.

[0173] In other examples, the medium channel 124 is fitted over the gas channel 132. In the axial direction of the gas channel 132, the length of the gas channel 132 can be the same as the length of the medium channel 124. That is, the medium channel 124 can share the entire wall of the gas channel 132 with the gas channel 132.

[0174] Reference Figure 9 In some embodiments of this utility model, the vent valve 130 is located at the bottom of at least a portion of the wall shared by the medium flow channel 124 and the gas channel 132.

[0175] In other words, the vent valve 130 is located at the end of the wall shared by the medium flow channel 124 and the gas channel 132 facing the internal space of the housing 110. It can also be understood that in the direction of gas flow from the external environment into the housing 110 through the vent valve 130, the vent valve 130 is located at the bottom of the wall shared by the medium flow channel 124 and the gas channel 132. This helps to extend the flow path of the gas in the external environment within the gas channel 132, thereby facilitating sufficient heat exchange of the gas entering the gas channel 132, improving the heat exchange effect of the gas, and enhancing the evaporation or condensation effect of the water vapor carried by the gas. This further helps to reduce the humidity of the gas entering the housing 110 through the vent valve 130.

[0176] like Figure 7 As shown, in some embodiments of this utility model, the medium flow channel 124 is connected to the inlet channel 121 and / or the outlet channel 122.

[0177] For example, the connector 120 is provided with a diversion port 125, which is used to connect the medium flow channel 124 with the inlet channel 121; and / or, the diversion port 125 is used to connect the medium flow channel 124 with the outlet channel 122.

[0178] In some examples, a diversion port 125 is provided between the inlet channel 121 and the medium flow channel 124. Part of the heat exchange medium flowing through the inlet channel 121 can flow into the medium flow channel 124 through the diversion port 125, so as to facilitate the delivery of heat exchange medium into the medium flow channel 124. By setting the diversion port 125, there is no need to set up additional pipelines or other structures for delivering heat exchange medium to the medium flow channel 124, which helps to simplify the structure of the anti-condensate water device 100, reduce the production cost of the anti-condensate water device 100, and at the same time improve the assembly convenience of the anti-condensate water device 100.

[0179] In some examples, a diversion port 125 is provided between the outlet channel 122 and the medium flow channel 124. Part of the heat exchange medium flowing through the outlet channel 122 can flow into the medium flow channel 124 through the diversion port 125, so as to facilitate the delivery of heat exchange medium into the medium flow channel 124. By setting the diversion port 125, there is no need to set up additional pipelines or other structures for delivering heat exchange medium to the medium flow channel 124, which helps to simplify the structure of the anti-condensate water device 100, reduce the production cost of the anti-condensate water device 100, and at the same time improve the assembly convenience of the anti-condensate water device 100.

[0180] In some examples, a diversion port 125 is provided between the inlet channel 121 and the medium flow channel 124, and a diversion port 125 is also provided between the outlet channel 122 and the medium flow channel 124. Part of the heat exchange medium flowing through the inlet channel 121 and part of the heat exchange medium flowing through the outlet channel 122 can flow into the medium flow channel 124 through the diversion port 125, so as to facilitate the delivery of heat exchange medium into the medium flow channel 124. By setting the diversion port 125, there is no need to set up additional pipelines or other structures for delivering heat exchange medium into the medium flow channel 124, which helps to simplify the structure of the anti-condensate water device 100, reduce the production cost of the anti-condensate water device 100, and improve the assembly convenience of the anti-condensate water device 100.

[0181] It is understandable that the specific location of the diversion port 125 can be determined according to actual production requirements, and no specific limitation is made here.

[0182] like Figure 7 As shown, in some embodiments of this utility model, a diversion port 125 can be provided between the inlet channel 121 and the medium flow channel 124, which is beneficial to improving the processing convenience of the connecting joint 120; or, multiple diversion ports 125 can be provided between the inlet channel 121 and the medium flow channel 124, and the multiple diversion ports 125 can be spaced apart in the axial direction of the medium flow channel 124. By providing multiple diversion ports 125, it is beneficial to improve the efficiency of the heat exchange medium flowing into the medium flow channel 124, thereby improving the efficiency of heat exchange in the gas channel 132.

[0183] In some embodiments of this utility model, a diversion port 125 may be provided between the outlet channel 122 and the medium flow channel 124, which is beneficial to improving the processing convenience of the connecting joint 120; or, multiple diversion ports 125 may be provided between the outlet channel 122 and the medium flow channel 124, and the multiple diversion ports 125 may be spaced apart in the axial direction of the medium flow channel 124. By providing multiple diversion ports 125, it is beneficial to improve the efficiency of the heat exchange medium flowing into the medium flow channel 124, thereby improving the efficiency of heat exchange in the gas channel 132.

[0184] It is understandable that the specific number of diversion ports 125 can be determined according to actual production requirements, and no specific limit is made here.

[0185] In some embodiments of this utility model, the vent valve 130 is integrated into the connector 120, so that the vent valve 130 and the connector 120 are integrated into one piece.

[0186] By integrating the vent valve 130 and the connector 120 into one piece, the integration of the connector 120 is improved, and the assembly process of the anti-condensation device 100 is simplified, thereby improving the production and assembly efficiency of the anti-condensation device 100.

[0187] In some embodiments of this utility model, the housing 110 is provided with an electrical component, which includes at least one of a power supply device and a power consumption device.

[0188] For example, the electrical component includes a power supply device that can store or provide electrical energy to power the waterproof condensation device 100 so that the waterproof condensation device 100 can operate normally; in other examples, the electrical component includes an electrical device that can use electrical energy to operate; in still other examples, the electrical component includes a power supply device and an electrical device that can provide electrical energy to the electrical device to use the electrical device to operate.

[0189] In some embodiments of this utility model, the power supply device includes a battery cell, and the power consumption device includes a heating electronic component. The battery cell can be electrically connected to the heating electronic component, and the battery cell can provide electrical energy to the heating electronic component so that the heating electronic component can work.

[0190] In some embodiments of this invention, the heat exchange component is also used to exchange heat for at least one of the power supply device and the power consumption device.

[0191] In some examples, considering that excessively high or low temperatures of the power supply device will affect its operating performance, heat exchange components can be used to exchange heat with the power supply device to ensure its temperature, prevent thermal runaway due to excessively high temperature, and at the same time help prevent the power supply device from degrading due to excessively low temperature.

[0192] In other examples, considering that excessively high or low temperatures of electrical devices can affect their performance, heat exchange components can be used to exchange heat with the electrical devices to maintain their temperature and thus ensure their performance.

[0193] In other examples, the heat exchange components can exchange heat for the power supply device and the power consumption device separately to ensure the temperature of the power supply device and the power consumption device, thereby helping to ensure the working performance of the power supply device and the power consumption device.

[0194] In some embodiments of this utility model, the heat exchange assembly includes a first heat exchange unit and a second heat exchange unit. The first heat exchange unit exchanges heat with the battery cell, and the second heat exchange unit exchanges heat with the heat-generating electronic components. The first heat exchange unit and the second heat exchange unit are different.

[0195] For example, both the heat-generating electronic components and the battery cells need to exchange heat during operation to ensure their performance and improve the safety of the anti-condensation device 100. By setting up a first heat exchange unit and a second heat exchange unit respectively, heat exchange can be performed on the battery cells and high-voltage components respectively.

[0196] The first heat exchange unit is different from the second heat exchange unit. For example, the first heat exchange unit and the second heat exchange unit are of different types, or the first heat exchange unit and the second heat exchange unit have different heat exchange areas. This is beneficial to enable the first heat exchange unit and the second heat exchange unit to meet the heat exchange requirements of the battery cell and the heat-generating electronic components, and at the same time, it is beneficial to improve the heat exchange effect of the battery cell and the heat-generating electronic components.

[0197] In some embodiments of this utility model, the heat exchange areas of the first heat exchange unit and the second heat exchange unit are different; or the heat exchange types of the first heat exchange unit and the second heat exchange unit are different.

[0198] For example, considering the different areas of the heat-generating electronic components and the battery cells, the heat exchange areas of the first heat exchange unit and the second heat exchange unit can be constructed differently, so that the heat exchange area of ​​the first heat exchange unit can be adapted to the heat exchange area of ​​the battery cells and the heat exchange area of ​​the second heat exchange unit can be adapted to the area of ​​the heat-generating electronic components. This is beneficial to improving the heat exchange efficiency between the battery cells and the heat-generating electronic components, and at the same time, it is beneficial to save the material cost of the heat exchange components, thereby reducing the production cost of the anti-condensation device 100.

[0199] In other examples, the heat exchange type of the first heat exchange unit is different from that of the second heat exchange unit.

[0200] Considering the different heat exchange requirements of heat-generating electronic components and battery cells, the heat exchange types of the first heat exchange unit and the second heat exchange unit can be set to be different. This is beneficial for adapting the heat exchange capacity of the first heat exchange unit to the heat exchange requirements of the battery cells and the heat exchange requirements of the second heat exchange unit to the heat exchange requirements of the heat-generating electronic components. This will help improve the heat exchange efficiency of the battery cells and the heat-generating electronic components and reduce the production cost of the heat exchange components.

[0201] In some embodiments of this utility model, the first heat exchange unit is a direct cooling unit and the second heat exchange unit is a liquid cooling unit, or the first heat exchange unit is a liquid cooling unit and the second heat exchange unit is a direct cooling unit.

[0202] Direct cooling units have lower production costs than liquid cooling units, while liquid cooling units have higher heat exchange efficiency than direct cooling units. Therefore, the specific configuration of the first and second heat exchange units can be determined based on the heat exchange requirements of the battery cells and heat-generating electronic components. No specific restrictions are imposed here, as long as the first and second heat exchange units can respectively meet the heat exchange requirements of the battery cells and heat-generating electronic components.

[0203] In some embodiments of this utility model, both the first heat exchange unit and the second heat exchange unit are provided with a connecting joint 120, one of which integrates a vent valve 130.

[0204] For example, such as Figure 1 As shown, the vent valve 130 can be integrated on the connection joint 120 of the first heat exchange unit. During the process of the heat exchange medium flowing into or out of the first heat exchange unit through the connection joint 120, the vent valve 130 can be heat exchanged, so that the water vapor carried by the gas flowing through the vent valve 130 can be condensed or evaporated, thereby reducing the humidity of the gas entering the internal space of the housing 110.

[0205] Alternatively, the vent valve 130 can be integrated into the connection joint 120 of the second heat exchange unit. During the process of the heat exchange medium flowing into or out of the second heat exchange unit through the connection joint 120, the vent valve 130 can be heat-exchanged, so that the water vapor carried by the gas flowing through the vent valve 130 can be condensed or evaporated, thereby reducing the humidity of the gas entering the internal space of the housing 110.

[0206] It is understandable that whether the vent valve 130 is integrated with the connection joint 120 of the first heat exchange unit or with the connection joint 120 of the second heat exchange unit can be determined according to actual production requirements, and no specific limitation is made here.

[0207] Reference Figure 9 In some other embodiments of this utility model, the vent valve 130 is disposed on the housing 110 and close to the connecting joint 120. The heat of the vent valve 130 can be transferred from the housing 110 to the connecting joint 120. The connecting joint 120 can absorb the heat of the vent valve 130 to exchange heat with the vent valve 130, so that the water vapor carried by the gas flowing through the vent valve 130 is condensed or evaporated, thereby reducing the humidity of the gas entering the internal space of the housing 110.

[0208] For example, the vent valve 130 can be embedded in the housing 110 and located above the connecting joint 120. The vent valve 130 is positioned close to the connecting joint 120 so that heat can be transferred between the vent valve 130 and the connecting joint 120 through the housing 110, which is beneficial to improving the heat exchange effect of the vent valve 130.

[0209] In this structural mode, there is no need to set up a channel for the flow of heat exchange medium on the radial outside of the gas channel 132, and there is no need to set up a diversion port 125, which helps to simplify the processing steps of the anti-condensation equipment 100, thereby improving the production convenience of the anti-condensation equipment 100.

[0210] Reference Figure 3 According to the embodiment of the present utility model, the vent valve 130 is provided with a vent membrane and a gas channel 132. The gas channel 132 is provided with a guide surface 1321 to guide liquid toward the outside of the housing 110.

[0211] For example, the lower part of the inner wall of the gas channel 132 can form a guide surface 1321. The condensate formed by the water vapor carried by the gas can flow along the guide surface 1321 in a direction away from the internal space of the box 110 to guide the condensate out. This helps to reduce the risk of condensate accumulating in the gas channel 132, thereby reducing the risk of condensate entering the internal space of the box 110.

[0212] According to the embodiment of the present invention, the vent valve 130 provides a guide surface 1321 in the gas channel 132 to facilitate the discharge of condensate from the gas channel 132, thereby reducing the risk of condensate accumulating in the gas channel 132.

[0213] Reference Figure 3 In some embodiments of the present invention, at least a portion of the inner wall surface of the gas channel 132 extends obliquely to form a guide surface 1321.

[0214] For example, the lower portion of the inner wall of the gas channel 132 can extend outward and downward to form an outward and downward inclined guide surface 1321. The guide surface 1321 can guide the discharge of condensate, which helps to reduce the risk of condensate accumulating in the gas channel 132, thereby reducing the risk of condensate entering the internal space of the housing 110.

[0215] It should be noted that "facing outward" can be understood as facing the direction away from the internal space of the box 110, and "facing downward" can be understood as facing the ground.

[0216] In some examples, the lower and upper portions of the inner wall of the gas channel 132 can extend outward and downward to form a guide surface 1321; in other examples, the entire inner wall of the gas channel 132 can extend outward and downward to form a guide surface 1321. Of course, it is understood that the specific formation method of the guide surface 1321 can be determined according to actual production requirements, and no specific limitation is made here, as long as the guide surface 1321 formed on the inner wall of the gas channel 132 can play the role of draining condensate.

[0217] In some embodiments of this utility model, the angle between the guide surface 1321 and the horizontal plane ranges from 1° to 45°.

[0218] In the above technical solution, by making the angle between the guide surface 1321 and the horizontal plane range from 1° to 45°, it is beneficial to ensure the guiding effect of the guide surface 1321 on the condensate, reduce the risk of condensate accumulating in the airflow channel, and at the same time improve the smoothness of gas flow.

[0219] When the angle between the guide surface 1321 and the horizontal plane is less than 1°, the guide surface 1321 has a poor guiding effect on condensate, and condensate is easy to accumulate in the gas channel 132, and may even cause condensate to enter the internal space of the box 110; when the angle between the guide surface 1321 and the horizontal plane is greater than 45°, the guide surface 1321 is easy to obstruct the flow of gas, making it difficult for gas to flow into the internal space of the box 110.

[0220] In some embodiments of this utility model, the inner wall surface of the gas channel 132 is provided with protrusions and / or grooves.

[0221] For example, the inner wall surface of the gas channel 132 may be provided with a plurality of tiny protrusions, or the inner wall surface of the gas channel 132 may be provided with a plurality of tiny grooves, or the inner wall surface of the gas channel 132 may be provided with a plurality of tiny protrusions and grooves. The tiny protrusions or grooves can increase the roughness of the inner wall surface of the gas channel 132, provide more nucleation sites for water vapor, and help improve the adsorption capacity of the inner wall surface of the gas channel 132 for water vapor, which is conducive to promoting the condensation of water vapor in the gas channel 132, thereby helping to reduce the humidity of the gas entering the chamber 110.

[0222] In some examples, protrusions and / or grooves can be mechanically provided on the inner wall surface of the gas channel 132, for example, by sandblasting to provide protrusions and / or grooves on the inner wall surface of the gas channel 132.

[0223] In other examples, protrusions and / or grooves can be provided on the inner wall of the gas channel 132 by chemical means, for example, protrusions and / or grooves can be provided on the inner wall of the gas channel 132 by chemical corrosion.

[0224] It is understandable that the specific manner in which the inner wall surface of the gas channel 132 is provided with protrusions and / or grooves can be determined according to actual production requirements, and no specific limitation is made here, as long as the roughness of the inner wall surface of the gas channel 132 can be effectively improved.

[0225] In some embodiments of this utility model, the roughness of the inner wall surface of the gas channel 132 can be in the range of 3μm-10μm.

[0226] For example, the roughness of the inner wall surface of the gas channel 132 can be 3μm, 4μm, 5μm or 10μm, etc. By limiting the roughness range of the inner wall surface of the gas channel 132 to 3μm-10μm, it is easier for condensate to adhere to the inner wall of the gas channel 132, and it is also beneficial to reduce the resistance of condensate when flowing along the inner wall surface of the gas channel 132, so as to facilitate the discharge of condensate through the gas channel 132 and reduce the risk of condensate remaining in the gas channel 132.

[0227] In some embodiments of this utility model, a filter screen 140 is provided in the gas channel 132 and / or the opening of the gas channel 132.

[0228] For example, the filter screen 140 can be set in the gas channel 132. When the gas flows into the gas channel 132 and flows towards the vent valve 130, it can pass through the filter screen 140. The water vapor carried by the gas can condense and gather on the filter screen 140, which is beneficial to improve the condensation effect of water vapor and reduce the humidity of the gas entering the internal space of the housing 110. At the same time, the filter screen 140 can filter impurities (such as large dust particles) to prevent the vent valve 130 from being blocked due to the accumulation of impurities on it.

[0229] In some examples, refer to Figure 4 The filter screen 140 can be set at the opening of the gas channel 132. That is, the filter screen 140 can be set at the end of the gas channel 132 away from the internal space of the housing 110. The water vapor carried by the gas can condense at the opening of the gas channel 132, which helps to reduce the risk of condensate entering the gas channel 132. This helps to reduce the risk of condensate entering the gas channel 132 and further flowing into the internal space of the housing 110. At the same time, by setting the filter screen 140 at the opening of the gas channel 132, it helps to reduce the risk of impurities entering the gas channel 132 and clogging the gas channel 132, thus helping to ensure the smooth flow of gas.

[0230] In some examples, filters 140 can be installed both inside the gas channel 132 and at its opening. This helps to further improve the effect of water vapor condensation, reduce the risk of condensate entering the gas channel 132, and thus reduce the risk of condensate entering the gas channel 132 further flowing into the internal space of the housing 110. At the same time, it helps to further reduce the risk of impurities clogging the gas channel 132 and the vent valve 130, thereby ensuring smooth gas flow.

[0231] It is understandable that the specific location of the filter 140 can be determined according to actual production requirements, and no specific limitation is made here.

[0232] like Figure 5 As shown, in some embodiments of the present invention, the filter screen 140 includes a mounting ring 141 and a screen body 142. The mounting ring 141 is provided on the outer periphery of the screen body 142, and the mounting ring 141 is detachably mounted to the inner wall of the gas channel 132.

[0233] For example, the mounting ring 141 can serve as a mounting carrier for the mesh body 142, providing support for the mesh body 142 and facilitating its installation. The mounting ring 141 can be detachably installed onto the inner wall of the gas channel 132, thereby enabling the filter screen 140 to be detachably assembled with the inner wall of the gas channel 132. This improves the ease of assembly of the filter screen 140 and facilitates its disassembly.

[0234] like Figure 7 As shown, according to the embodiment of the present utility model, the connecting joint 120 is provided with a medium flow channel 124 for the flow of heat exchange medium, and the connecting joint 120 is provided with a fixing part for fixing the vent valve 130.

[0235] For example, the heat exchange medium can flow into the connecting joint 120 through the medium flow channel 124 to exchange heat with the connecting joint 120. The vent valve 130 can be fixed to the connecting joint 120 by the fixing part. The heat transferred by the heat exchange medium to the connecting joint 120 can be further transferred to the vent valve 130 to exchange heat with the vent valve 130. The vent valve 130 can exchange heat with the gas flowing through it so that the water vapor carried by the gas evaporates or condenses into condensate, thereby reducing the humidity of the gas flowing through the vent valve 130.

[0236] According to the embodiment of the present invention, the connecting joint 120 is provided with a medium flow channel 124 to facilitate the flow of heat exchange medium into the connecting joint 120, thereby facilitating heat exchange between the heat exchange medium and the connecting joint 120. The connecting joint 120 is provided with a fixing part so that the vent valve 130 can be installed on the connecting joint 120. The heat transferred by the heat exchange medium to the connecting joint 120 can be further transferred to the vent valve 130 to exchange heat with the vent valve 130. The vent valve 130 can exchange heat with the gas flowing through it, so that the water vapor carried by the gas evaporates or condenses into condensate, thereby reducing the humidity of the gas flowing through the vent valve 130.

[0237] Reference Figure 7 In some embodiments of this utility model, the fixing part is a gas channel 132 provided in the connecting joint 120, and the vent valve 130 is provided in the gas channel 132.

[0238] For example, the gas channel 132 can extend on the connecting joint 120 from the direction away from the internal space of the housing 110 to the direction close to the internal space of the housing 110. The vent valve 130 is disposed in the gas channel 132. The heat transferred by the heat exchange medium to the connecting joint 120 can be further transferred to the vent valve 130 to exchange heat with the vent valve 130.

[0239] Combination Figure 7 and Figure 9 The medium flow channel 124 and the gas channel 132 are nested together.

[0240] For example, one of the gas channel 132 and the medium flow channel 124 is disposed inside the other. That is, the gas channel 132 and the medium flow channel 124 form an inclusive relationship. It can also be understood that the medium flow channel 124 and the gas channel 132 share at least a portion of the wall surface. The medium flow channel 124 is circulated with a heat exchange medium, so that the heat exchange medium entering the medium flow channel 124 can fully contact the gas channel 132. This is beneficial to improving the heat exchange effect between the heat exchange medium and the gas channel 132, thereby improving the heat exchange effect on the gas channel 132 and the vent valve 130. This is beneficial to improving the condensation or evaporation effect of water vapor carried by the gas in the gas channel 132, and thus helping to reduce the humidity of the gas entering the internal space of the housing 110.

[0241] In some embodiments of this utility model, the heat exchange medium is a refrigerant or coolant to improve the heat exchange efficiency of the heat exchange component, thereby improving the heat exchange efficiency of the connecting joint 120 to the gas in the gas channel 132, and further reducing the humidity of the gas entering the housing 110.

[0242] The battery pack according to an embodiment of the present utility model includes an anti-condensation device 100, which is the anti-condensation device 100 described above; or a vent valve 130, which is the vent valve 130 described above; or a connecting joint 120, which is the connecting joint 120 described above.

[0243] Since the battery pack includes the aforementioned anti-condensation device 100, the aforementioned vent valve 130, or the aforementioned connecting joint 120, the humidity of the gas entering the battery pack can be effectively reduced, thereby helping to reduce the risk of corrosion or short circuit in the internal structure of the battery pack.

[0244] The vehicle according to the present invention includes the above-described anti-condensation device 100, the above-described vent valve 130, the above-described connector 120, or the above-described battery pack.

[0245] Since the vehicle includes the aforementioned anti-condensation device 100, the aforementioned vent valve 130, the aforementioned connector 120, or the aforementioned battery pack, the humidity of the gas entering the battery pack can be effectively reduced, thereby reducing the risk of corrosion or short circuits in the internal structure of the battery pack and thus improving the safety of vehicle use.
