Currently, the radiator on the electrical control box has poor heat dissipation effect and cannot meet the heat dissipation requirements of the electrical control box under harsh working conditions or extreme conditions. Utility Model Content

[0003] In order to overcome the problems existing in the related art, the present disclosure provides a radiator and an air conditioner. The radiator has good heat dissipation effect and can meet the heat dissipation requirements of the equipment to be cooled under harsh working conditions or extreme conditions.

[0004] In order to achieve the above-mentioned purpose, according to the first aspect of the present disclosure, a radiator is provided, which includes a heat dissipation fin; a sealed refrigerant tube is provided at one end of the heat dissipation fin, and an evaporation chamber, a decompression chamber and a condensation chamber are provided in the refrigerant tube from bottom to top, the evaporation chamber is used to store liquid refrigerant medium, and the decompression chamber is connected between the evaporation chamber and the condensation chamber.

[0005] Optionally, the volume of the evaporation chamber is greater than the volume of the condensation chamber.

[0006] Optionally, the evaporation chamber has two first side walls arranged opposite to each other, and the two first side walls gradually approach each other from bottom to top; the condensation chamber has two second side walls arranged opposite to each other, and the two second side walls gradually move away from each other from bottom to top.

[0007] Optionally, the decompression chamber has two third side walls arranged opposite to each other, the two third side walls are arranged in parallel, and the interval between the two third side walls is less than or equal to 1 mm to 2 mm.

[0008] Optionally, the angle between the two second side walls is less than or equal to 80°-100°, and / or the angle between the two first side walls is greater than or equal to 80°-100°.

[0009] Optionally, the radiator is provided with a liquid injection hole connected to the refrigerant pipe, and the liquid injection hole is arranged above the liquid level of the refrigerant medium.

[0010] Optionally, the radiator further includes a sealing plug, and the sealing plug is interference-fitted in the liquid injection hole.

[0011] Optionally, the sealing plug is disposed in the liquid injection hole in a shape-fitting manner, wherein a cross-section of the sealing plug is configured as a D-shaped surface, and the D-shaped surface includes a connected arc surface and a bottom plane.

[0012] Optionally, the refrigerant pipe is constructed in a continuously bent shape and has a first pipe section and a second pipe section that are alternately connected in sequence.

[0013] According to a second aspect of the present disclosure, there is provided an air conditioner, comprising an electric control box and a radiator provided on the electric control box, wherein the radiator is the above-mentioned radiator.

[0014] Through the above technical solution, in the radiator provided by the present invention, an evaporation chamber, a decompression chamber and a condensation chamber are sequentially arranged in the refrigerant tube from bottom to top, wherein the evaporation chamber is used to store liquid refrigerant. In this way, when the temperature of the evaporation chamber reaches the evaporation temperature of the refrigerant, the liquid refrigerant can absorb heat and evaporate into a gaseous refrigerant, and enter the condensation chamber through the decompression chamber. As the refrigerant in the evaporation chamber continues to evaporate, more and more gaseous refrigerant accumulates in the condensation chamber. That is to say, the air pressure in the condensation chamber will become larger and larger. In this way, the gaseous refrigerant in the condensation chamber will be liquefied under a high-pressure environment to be converted into a liquid refrigerant. The liquefied liquid refrigerant can flow back to the evaporation chamber under the action of its own gravity for the next heat absorption evaporation. In addition, the air pressure in the decompression chamber is lower than the air pressure in the evaporation chamber, which is conducive to guiding the gaseous refrigerant in the evaporation chamber to flow to the decompression chamber, and continuously flow into the condensation chamber through the decompression chamber to increase the air pressure in the condensation chamber and improve the condensation effect. In summary, the refrigerant medium can dissipate heat by absorbing heat through evaporation. That is to say, the radiator can dissipate heat through the cooling fins and the refrigerant medium at the same time. Therefore, the radiator has a good heat dissipation effect and can meet the heat dissipation needs of the equipment to be cooled (such as the electrical control box of the outdoor unit) under harsh working conditions or extreme conditions.

DETAILED DESCRIPTION

[0028] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0029] In the present disclosure, unless otherwise specified, the directional words used in the present disclosure, such as "up" and "down", generally refer to the "up" and "down" in the direction of gravity when the corresponding components are in use, and "top" and "bottom" refer to the "top" and "bottom" in the height direction when the present disclosure is in use. The terms "first", "second", etc. used in the present disclosure are intended to distinguish one element from another and do not have order or importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.

[0030] According to a first aspect of the present disclosure, a radiator is provided, Figure 2 and Figure 8 As shown in the figure, the radiator includes a heat dissipation fin 100; a sealed refrigerant tube 200 is provided at one end of the heat dissipation fin 100, and an evaporation chamber 230, a decompression chamber 210 and a condensation chamber 220 are provided in the refrigerant tube 200 from bottom to top. The evaporation chamber 230 is used to store liquid refrigerant 600, and the decompression chamber 210 is connected between the evaporation chamber 230 and the condensation chamber 220.

[0031] Through the above technical solution, in the radiator provided by the present disclosure, an evaporation chamber 230, a decompression chamber 210 and a condensation chamber 220 are sequentially arranged in the refrigerant tube 200 from bottom to top, wherein the evaporation chamber 230 is used to store the liquid refrigerant 600. In this way, when the temperature of the evaporation chamber 230 reaches the evaporation temperature of the refrigerant 600, the liquid refrigerant 600 can absorb heat and evaporate into a gaseous refrigerant 600, and enter the condensation chamber 220 through the decompression chamber 210. As the refrigerant 600 in the evaporation chamber 230 continues to evaporate, the gaseous refrigerant 600 accumulated in the condensation chamber 220 will also become more and more. In other words, the air pressure in the condensing chamber 220 will become increasingly greater. Thus, the gaseous refrigerant 600 in the condensing chamber 220 will liquefy under the high-pressure environment and transform into liquid refrigerant 600. The liquefied liquid refrigerant 600 can then flow back to the evaporating chamber 230 under its own gravity for the next heat-absorbing evaporation. Furthermore, the air pressure in the decompression chamber 210 is lower than that in the evaporating chamber 230, which facilitates guiding the gaseous refrigerant 600 in the evaporating chamber 230 to flow toward the decompression chamber 210 and continuously flow into the condensing chamber 220 through the decompression chamber 210, thereby increasing the air pressure in the condensing chamber 220 and improving the condensation effect. In summary, the refrigerant 600 can dissipate heat by absorbing heat through evaporation. In other words, the radiator can dissipate heat simultaneously through the heat dissipation fins 100 and the refrigerant 600. Therefore, the radiator has a good heat dissipation effect and can meet the heat dissipation requirements of the heat dissipation equipment (such as the electrical control box of an outdoor unit) under harsh or extreme conditions.

[0032] It should be noted that, since the refrigerant tube 200 is sealed, that is, the refrigerant medium 600 in the refrigerant tube 200 does not participate in the cooling or heating cycle of the air conditioner, there is no need to consider the connection between the refrigerant tube 200 and the heat dissipation pipeline of the air conditioner, and the refrigerant medium 600 in the refrigerant tube 200 can circulate back and forth in the refrigerant tube 200 to evaporate and liquefy, thereby avoiding loss. In addition, the heat dissipation fins 100 can dissipate heat through the radiator's cooling fan, and the refrigerant tube 200 can dissipate heat through the refrigerant medium 600. In other words, the radiator provided by this application uses a combination of air cooling and liquid cooling to dissipate heat, and has a good heat dissipation effect.

[0033] In the heat sink provided by the present disclosure, the evaporation chamber 230 and the condensation chamber 220 can be configured in any suitable manner. As an exemplary embodiment, the volume of the evaporation chamber 230 can be larger than the volume of the condensation chamber 220. This facilitates heat exchange between the evaporation chamber 230 and the refrigerant 600. In other words, it facilitates the transfer of heat absorbed by the evaporation chamber 230 to the refrigerant 600, thereby increasing the evaporation rate of the refrigerant 600. The evaporation rate of the refrigerant 600 is greater than the liquefaction rate, achieving a better heat dissipation effect.

[0034] The evaporation chamber 230 and the condensation chamber 220 can be configured in any suitable shape. As an exemplary embodiment, refer to Figures 5 to 8As shown in , the evaporation chamber 230 may have two first side walls 231 arranged opposite to each other, and the two first side walls 231 may gradually approach each other from bottom to top; the condensation chamber 220 may have two second side walls 221 arranged opposite to each other, and the two second side walls 221 may gradually move away from each other from bottom to top. In this way, the distance between the two first side walls 231 gradually decreases from bottom to top, which is conducive to guiding the gaseous refrigerant 600 from the evaporation chamber 230 into the decompression chamber 210, and finally reaching the condensation chamber 220 through the decompression chamber 210, so as to prevent the gaseous refrigerant 600 from accumulating in the evaporation chamber 230 and affecting the evaporation effect of the refrigerant 600; at the same time, the distance between the two second side walls 221 gradually decreases from top to bottom, which is conducive to guiding the liquid refrigerant 600 in the condensation chamber 220 to flow smoothly into the decompression chamber 210, and finally reaching the evaporation chamber 230 through the decompression chamber 210, so as to prevent the liquid refrigerant 600 from accumulating in the condensation chamber 220 and affecting the heat dissipation effect of the refrigerant 600. That is to say, the refrigerant tube 200 disclosed in the present invention can be regarded as a Venturi tube. Since the decompression chamber 210 is connected to the narrowest part of the evaporation chamber 230 and the narrowest part of the condensation chamber 220, when the gaseous refrigerant medium 600 flows in the evaporation chamber 230, the flow rate in the decompression chamber 210 is greater than the flow rate in the evaporation chamber 230, and the air pressure in the decompression chamber 210 is less than the air pressure in the evaporation chamber 230. In this way, the gas will automatically flow to the decompression chamber 210 and enter the condensation chamber 220, thereby realizing the concentrated flow of gas to the condensation chamber 220, which is beneficial to improving the condensation effect of the gaseous refrigerant medium 600.

[0035] In the heat sink provided by the present disclosure, the decompression chamber 210 can be constructed in any suitable manner. As an exemplary embodiment, refer to Figures 5 to 8As shown in , the decompression chamber 210 can have two third side walls 211 arranged opposite to each other. The two third side walls 211 can be arranged in parallel, and the interval between the two third side walls 211 can be less than or equal to 1 mm to 2 mm. In other words, a narrow decompression chamber 210 can be formed between the two third side walls 211 to form a narrow tube effect in the decompression chamber 210. Specifically, when the gaseous refrigerant 600 enters the decompression chamber 210 from the evaporation chamber 230, because the space of the decompression chamber 210 is much smaller than the space of the evaporation chamber 230, the flow rate of the refrigerant 600 will increase, so that it can quickly pass through the decompression chamber 210 and enter the condensation chamber 220. In other words, the above-mentioned design of the third side walls 211 can accelerate the speed at which the gaseous refrigerant 600 enters the condensation chamber 220, thereby further increasing the rate at which the refrigerant 600 converts between evaporation and liquefaction, thereby achieving the purpose of enhancing the heat exchange effect. Among them, the interval between the two third side walls 211 can be recorded as W. It should be noted that the smaller W is, the more obvious the narrow tube effect is. In the actual production process, W can be appropriately selected according to actual needs, such as 0.5mm, 1mm, 1.5mm, 2mm, etc., and this disclosure does not make specific restrictions on this.

[0036] In the heat sink provided by the present disclosure, the second side wall 221 and the first side wall 231 can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 8 As shown in , the angle between the two second side walls 221 can be less than or equal to 80°~100°. And / or, the angle between the two first side walls 231 can be greater than or equal to 80°~100°. Among them, the angle between the two second side walls 221 can be recorded as β. In the actual production process, β can be selected from any suitable value, such as 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, etc. The present disclosure does not impose specific restrictions on this. In a specific embodiment, β can preferably be 60°. The smaller the angle value selected for β, the faster the second side wall 221 guides the liquid refrigerant 600, which can accelerate the rate of conversion of the refrigerant 600 between evaporation and liquefaction. In addition, the angle between the two first side walls 231 can be recorded as α. In the actual production process, α can be selected from any suitable value, such as 80°, 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, etc. The present disclosure does not impose specific restrictions on this. In a specific embodiment, α can preferably be 120°.

[0037] As an exemplary embodiment, reference is made to Figures 3 to 5 As shown in FIG and , the refrigerant pipe 200 can be set in the connection base 400 of the radiator. Specifically, the radiator can include a connection base 400 and a heat dissipation fin 100 connected to at least one side of the connection base 400 (wherein, Figure 3 (The example in which the heat dissipation fins 100 are provided on one side of the connecting base 400 is used only for illustration and does not constitute a limitation to the present application.) The interior of the connecting base 400 is hollow to form a refrigerant tube 200. In this way, there is no need to install an additional refrigerant tube 200 on the radiator, which can reduce the cost and weight of the radiator. In this embodiment, the angle value selected for β can be smaller than the angle value selected for α. In this way, when the size of the connecting base 400 in the up-down direction is limited, the sizes of the evaporation chamber 230 and the condensation chamber 220 in the up-down direction will both be limited. In actual design, the size of the evaporation chamber 230 in the up-down direction can be made equal to the size of the condensation chamber 220 in the up-down direction. In this way, the design in which the angle value selected for β is smaller than the angle value selected for α can ensure that the volume of the evaporation chamber 230 is larger than the volume of the condensation chamber 220. In this embodiment, β can be less than 90°, and α can be greater than 90° and less than 180°.

[0038] In the heat sink provided by the present disclosure, as an exemplary embodiment, reference is made to Figures 1 to 3 as well as Figure 7 As shown in FIG, the radiator may be provided with an injection hole 300 connected to the refrigerant tube 200. The injection hole 300 may be positioned above the liquid level of the refrigerant 600. In this way, the refrigerant 600 can be injected into the refrigerant tube 200 through the injection hole 300. Positioning the injection hole 300 above the liquid level of the refrigerant 600 prevents the refrigerant 600 from overflowing the injection hole 300 and causing waste.

[0039] In the heat sink provided by the present disclosure, as an exemplary embodiment, reference is made to Figure 3 and Figure 9 As shown in , the radiator may further include a sealing plug 500, which may be interference-fitted into the liquid injection hole 300. In this way, the purpose of sealing the refrigerant pipe 200 can be achieved through the sealing plug 500.

[0040] In the heat sink provided by the present disclosure, as an exemplary embodiment, reference is made to Figure 9 As shown in FIG, the sealing plug 500 can be disposed in a form-fitting manner in the liquid injection hole 300. The cross-section of the sealing plug 500 can be configured as a D-shaped surface, which can include a connected arcuate surface 510 and a bottom plane 520. Thus, the special-shaped sealing plug 500 facilitates quick alignment and installation by workers, thereby improving work efficiency.

[0041] In the radiator provided by the present disclosure, the refrigerant pipe 200 can be configured in any suitable shape. As an exemplary embodiment, refer to Figure 4As shown in , the refrigerant tube 200 can be constructed in a continuously bent shape and have a first tube section 240 and a second tube section 250 that are alternately connected in sequence. In this way, the refrigerant tube 200 can be evenly distributed in the radiator, while also increasing the heat dissipation area of ​​the refrigerant tube 200. In addition, the above design only requires one refrigerant tube 200, which can simplify the number of refrigerant tubes 200, injection holes 300, and sealing plugs 500 to reduce costs. In other embodiments, the number of refrigerant tubes 200 can also be multiple, and the multiple refrigerant tubes 200 can be constructed in a straight line arranged at intervals along the length direction or width direction of the connecting seat 400. In this way, the processing difficulty of the refrigerant tube 200 can be reduced.

[0042] According to a second aspect of the present disclosure, an air conditioner is provided, comprising an electrical control box and a radiator disposed on the electrical control box. The radiator is the aforementioned radiator. Thus, the air conditioner exhibits all of the aforementioned beneficial effects. When the temperature of the electrical control box is high, the refrigerant 600 can evaporate and absorb heat to lower the temperature of the electrical control box, while the heat dissipation fins 100 can dissipate heat via a cooling fan to lower the temperature of the electrical control box. The combination of these two methods can enhance the heat dissipation effect of the radiator on the electrical control box, thereby ensuring the thermal safety of electronic components. Furthermore, the radiator, which utilizes a combination of air cooling and liquid cooling, achieves excellent heat dissipation and can improve the overall performance of the air conditioner.

[0043] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0044] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0045] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
