Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, and more specifically, to a cooling device and a cooling system having the same. Background Technology

[0002] Currently, in the industrial sector, many production processes require precise temperature control. For example, in certain chemical reactions, specific chemical reactions need to be carried out at low temperatures to ensure reaction efficiency and product quality. The pharmaceutical industry also has strict low-temperature requirements for drug synthesis and purification steps to prevent drug deterioration or side reactions. In the food processing industry, cooling and preservation processes in dairy and meat processing require a continuously stable low-temperature environment. In the air conditioning system field, especially large-scale central air conditioning systems, maintaining a continuously stable low-temperature environment is essential for achieving large-area indoor cooling.

[0003] In existing technologies, to meet the low-temperature requirements of production environments, manufacturers typically use water tank evaporators to provide stable and reliable low-temperature refrigerants for industrial production. Specifically, a water tank evaporator mainly involves placing the evaporator in a water tank, with the refrigerant circulating into the tank. The refrigerant in the evaporator absorbs heat through evaporation, cooling the refrigerant in the tank. The cooled refrigerant can then be delivered to the corresponding production environment, thereby ensuring the reliability of cooling in the production environment.

[0004] However, after the circulating refrigerant flows into the water tank, most of it only comes into contact with part of the evaporator before flowing out, which reduces the heat exchange efficiency between the evaporator and the refrigerant, and thus reduces the cooling effect of the water tank evaporator. Utility Model Content

[0005] The main objective of this invention is to provide a cooling device and a cooling system having the same, in order to solve the problem of poor cooling effect of water tank evaporators in the prior art.

[0006] To achieve the above objectives, according to one aspect of the present invention, a cooling device is provided, comprising: a housing having an inlet, an outlet, and a receiving cavity, wherein both the inlet and outlet are connected to the receiving cavity, and the receiving cavity is used to contain a cooling medium; a heat exchange structure disposed within the receiving cavity to cool the cooling medium; and a flow-retarding assembly disposed within the receiving cavity, the flow-retarding assembly comprising multiple flow-retarding structures spaced apart along a predetermined direction, with adjacent flow-retarding structures forming a flow-retarding channel, wherein the cooling medium flows through the multiple flow-retarding channels and then contacts the heat exchange structure; wherein the flow-retarding structure has a flow-blocking portion that contacts at least a portion of the cooling medium to slow down the flow rate of the cooling medium.

[0007] Furthermore, the flow-retarding structure is arranged in a curved shape; the protruding part of the curve forms a flow-blocking part.

[0008] Furthermore, the flow-slowing component also includes a support structure, which is disposed within the receiving cavity and is plate-shaped; wherein, multiple flow-slowing structures are disposed on the support structure and spaced apart along a preset direction.

[0009] Furthermore, the heat exchange structure divides the housing into a first chamber and a second chamber. The slow-flow component and the liquid inlet are located in the first chamber, and the liquid outlet is located in the second chamber. The cooling medium flows through the gaps in the heat exchange structure itself and / or the gaps between the heat exchange structure and the housing before flowing out of the liquid outlet.

[0010] Furthermore, the cooling device also includes: a support structure disposed within the receiving cavity, the support structure having a support portion, the support portion being plate-shaped; wherein, there are multiple heat exchange structures, the multiple heat exchange structures being spaced apart along the length or width direction of the support portion.

[0011] Furthermore, the cooling device also includes a connecting structure, at least part of which is disposed within the receiving cavity. The connecting structure has a liquid inlet and an air outlet. The liquid inlet is connected to the air outlet via a heat exchange structure. Both the liquid inlet and the air outlet extend outside the casing and are connected to external equipment.

[0012] Furthermore, the inlet and outlet are located on two opposite sides of the housing, and the height H1 of the inlet and the height H2 of the outlet satisfy the condition: H2 < H1.

[0013] Furthermore, the cooling device also includes a pump body structure, which is connected to the liquid inlet or the liquid outlet to drive the flow of the cooling medium.

[0014] Furthermore, the cooling device also includes a filter structure located at the liquid inlet to filter the cooling medium.

[0015] This application also provides a cooling system, which includes the cooling device described above.

[0016] The present invention relates to a cooling device whose housing includes an inlet, an outlet, and a receiving cavity. Both the inlet and outlet are connected to the receiving cavity, which contains the cooling medium. A heat exchange structure is disposed within the receiving cavity to cool the cooling medium. A flow-retarding assembly is disposed within the receiving cavity and includes multiple flow-retarding structures spaced apart along a predetermined direction. Adjacent flow-retarding structures form a flow-retarding channel, through which the cooling medium flows and contacts the heat exchange structure. Each flow-retarding structure has a flow-blocking portion that contacts at least a portion of the cooling medium to slow its flow rate. Thus, after entering the receiving cavity through the inlet, the cooling medium flows into the multiple flow-retarding channels formed by the flow-retarding structures, preventing the cooling medium from directly flowing into the receiving cavity and forming transverse eddies. This allows the cooling medium to contact the heat exchange structure through the flow-retarding channels, ensuring reliable heat exchange between the cooling medium and the heat exchange structure. Meanwhile, the flow-blocking section of the slow-flow structure can collide with the cooling medium, further slowing down the flow rate of the cooling medium. This allows the cooling medium to have sufficient contact with the heat exchange structure, increasing the heat exchange area between the cooling medium and the heat exchange structure, improving heat exchange efficiency, and reducing the temperature of the cooling medium. This ensures the cooling effect of the cooling medium and solves the problem of poor cooling performance in existing water tank evaporators. Furthermore, the slow-flow channels formed around adjacent slow-flow structures simplify the formation of these channels, facilitating processing and installation. Attached Figure Description

[0031] To address the problem of poor cooling performance in existing water tank evaporators, this application provides a cooling device and a cooling system having the same.

[0032] like Figures 1 to 4 As shown, the cooling device housing 10 has a liquid inlet 11, a liquid outlet 12, and a receiving cavity 13. Both the liquid inlet 11 and the liquid outlet 12 are connected to the receiving cavity 13, which is used to contain the cooling medium. A heat exchange structure 20 is disposed within the receiving cavity 13 to cool the cooling medium. A flow-regulating assembly 30 is disposed within the receiving cavity 13. The flow-regulating assembly 30 includes multiple flow-regulating structures 31, which are spaced apart along a predetermined direction. Adjacent flow-regulating structures 31 form a flow-regulating channel 33. After flowing through the multiple flow-regulating channels 33, the cooling medium comes into contact with the heat exchange structure 20. Each flow-regulating structure 31 has a flow-blocking portion 311, which contacts at least a portion of the cooling medium to slow its flow rate.

[0033] Applying the technical solution of this embodiment, the housing 10 of the cooling device has a liquid inlet 11, a liquid outlet 12, and a receiving cavity 13. Both the liquid inlet 11 and the liquid outlet 12 are connected to the receiving cavity 13, which is used to contain the cooling medium. A heat exchange structure 20 is disposed within the receiving cavity 13 to cool the cooling medium. A flow-retarding assembly 30 is disposed within the receiving cavity 13. The flow-retarding assembly 30 includes multiple flow-retarding structures 31, which are spaced apart along a predetermined direction. Adjacent flow-retarding structures 31 form a flow-retarding channel 33. After flowing through the multiple flow-retarding channels 33, the cooling medium comes into contact with the heat exchange structure 20. The flow-retarding structure 31 has a flow-blocking portion 311, which contacts at least a portion of the cooling medium to slow its flow rate. In this way, after the cooling medium enters the receiving cavity 13 through the inlet 11, it flows into multiple slow-flow channels 33 formed by multiple slow-flow structures 31. This avoids the cooling medium directly flowing into the receiving cavity 13 and forming a transverse vortex, allowing the cooling medium to contact the heat exchange structure 20 through the slow-flow channels 33, ensuring the reliability of heat exchange between the cooling medium and the heat exchange structure 20. At the same time, the flow-blocking part 311 of the slow-flow structure 31 can collide with the cooling medium, further slowing down the flow rate of the cooling medium, allowing the cooling medium to have sufficient contact with the heat exchange structure 20, increasing the heat exchange area between the cooling medium and the heat exchange structure 20, improving heat exchange efficiency, and reducing the temperature of the cooling medium, thereby ensuring the cooling effect of the cooling medium and solving the problem of poor cooling effect in the existing water tank evaporator. In addition, the slow-flow channels 33 formed by adjacent slow-flow structures 31 make the formation of the slow-flow channels 33 simpler and more convenient for workers to process and install.

[0034] In this embodiment, the cooling medium is water.

[0035] like Figure 2 and Figure 4 As shown, the flow-retarding structure 31 is arranged in a curved shape. The protruding part of the curve forms the flow-blocking part 311. In this way, the protruding part of the flow-retarding structure 31 forms the flow-blocking part 311, which makes the formation of the flow-blocking part 311 simpler, reduces the processing difficulty for workers, and also ensures the economy of the cooling device.

[0036] In this embodiment, the slow-flow structure 31 is arranged in a wave-like shape.

[0037] like Figure 4As shown, the flow-slowing assembly 30 also includes a support structure 32, which is plate-shaped and disposed within the receiving cavity 13. Multiple flow-slowing structures 31 are disposed on the support structure 32 and spaced apart along a predetermined direction. This arrangement of the support structure 32 supports the multiple flow-slowing structures 31, ensuring their installation stability and thus guaranteeing the flow stability of the cooling medium within the multiple flow-slowing channels 33, further ensuring the cooling effect of the cooling medium.

[0038] In this embodiment, the support structure 32 is disposed on one side of the box 10, and a plurality of flow-slowing structures 31 are spaced apart along the length of the support structure 32.

[0039] In this embodiment, two support members are also provided inside the housing 10. The two support members are provided on two opposite sides of the housing 10 to connect with two of the multiple flow-slowing structures 31 located at the ends, so as to further improve the installation stability of the flow-slowing structures 31.

[0040] like Figure 2 and Figure 4 As shown, the heat exchange structure 20 divides the receiving cavity 13 into a first chamber 131 and a second chamber 132. The slow-flow component 30 and the liquid inlet 11 are located in the first chamber 131, and the liquid outlet 12 is located in the second chamber 132. The cooling medium flows through the gaps in the heat exchange structure 20 itself and / or the gaps between the heat exchange structure 20 and the housing 10 before flowing out through the liquid outlet 12. In this way, the above arrangement defines the specific positions of the slow-flow component 30 and the liquid inlet 11, so that the cooling medium first flows into the first chamber 131 through the liquid inlet 11, and then flows to the heat exchange structure 20 through the slow-flow channel 33 in the first chamber 131. After making full contact with the heat exchange structure 20, it flows out from the liquid outlet 12 in the second chamber 132, so that the cooling medium can exchange heat with the heat exchange structure 20 to the maximum extent, further improving the cooling effect of the cooling medium.

[0041] Specifically, the cooling device also includes a support structure. The support structure is disposed within the receiving cavity 13 and has a support portion 50, which is plate-shaped. Multiple heat exchange structures 20 are arranged at intervals along the length or width of the support portion 50. This arrangement of the support structure ensures the support of the heat exchange structures 20, guaranteeing their installation stability and reliability. This allows multiple heat exchange structures 20 to be stably installed within the housing 10, increasing the heat exchange efficiency between the heat exchange structures 20 and the cooling medium, improving the cooling effect of the cooling medium, and ultimately enhancing the cooling effect of the cooling device.

[0042] In this embodiment, multiple heat exchange structures 20 are spaced apart along the length of the support portion 50.

[0043] In this embodiment, two load-bearing structures are provided, which are set on two opposite sides of the housing 10 for installation at both ends of the heat exchange structure 20.

[0044] It should be noted that the number of load-bearing structures is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the number of load-bearing structures can be three, four, five, eight, or more.

[0045] like Figures 1 to 4 As shown, the cooling device also includes a connecting structure 40, at least partially disposed within the receiving cavity 13. The connecting structure 40 has a liquid inlet 41 and an air outlet 42. The liquid inlet 41 is connected to the air outlet 42 via a heat exchange structure 20. Both the liquid inlet 41 and the air outlet 42 extend outside the housing 10 and are connected to external equipment. In this way, the heat exchange structure 20 achieves connection with external equipment through the liquid inlet 41 and the air outlet 42, ensuring the operational reliability of the heat exchange structure 20.

[0046] In this embodiment, the heat exchange structure 20 is a shell-and-tube heat exchanger. External equipment delivers the refrigerant to the heat exchange chamber through the liquid inlet 41. The refrigerant is converted into a gaseous state within the heat exchange chamber and then delivered to the external equipment through the gas outlet 42 for subsequent use. During the conversion from liquid to gas, the refrigerant absorbs heat from the cooling medium, thereby reducing its temperature and ensuring its cooling effect. Furthermore, this design allows for the recycling of the refrigerant, improving the economic efficiency of the cooling device.

[0047] Specifically, the refrigerant is Freon.

[0048] Alternatively, the heat exchange structure 20 can also be other devices capable of exchanging heat with the cooling medium.

[0049] like Figure 1 and Figure 2 As shown, the inlet 11 and outlet 12 are located on two opposite sides of the housing 10, and the height H1 of the inlet 11 and the height H2 of the outlet 12 satisfy the condition: H2 < H1. This arrangement allows the cooling medium to enter the receiving cavity 13 from the inlet 11 under its own gravity and flow out from the outlet 12, ensuring smooth flow and reliable cooling performance.

[0050] Specifically, the cooling device also includes a pump body structure, which is connected to the liquid inlet 11 or the liquid outlet 12 to drive the flow of the cooling medium. In this way, the pump body structure can drive the flow of the cooling medium, making the flow of the cooling medium smoother, ensuring the circulation of the cooling medium, and improving the cooling effect of the cooling medium.

[0051] Specifically, the cooling device also includes a filter structure located at the liquid inlet 11 to filter the cooling medium. In this way, the cooling medium entering the liquid inlet 11 can be filtered by the filter structure, ensuring the cleanliness of the cooling medium, preventing impurities from being carried by the cooling medium and thus avoiding a reduction in heat exchange efficiency, further ensuring the cooling effect of the cooling medium.

[0052] This application also provides a cooling system, which includes the cooling device described above.

[0053] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0054] The cooling device housing has a liquid inlet, a liquid outlet, and a receiving cavity. Both the liquid inlet and outlet are connected to the receiving cavity, which is used to contain the cooling medium. A heat exchange structure is disposed within the receiving cavity to cool the cooling medium. A flow-regulating assembly is disposed within the receiving cavity and includes multiple flow-regulating structures spaced apart along a predetermined direction. Adjacent flow-regulating structures form flow-regulating channels, through which the cooling medium flows and then contacts the heat exchange structure. Each flow-regulating structure has a flow-blocking section that contacts at least a portion of the cooling medium to slow its flow rate. Thus, after the cooling medium enters the receiving cavity through the liquid inlet, it flows into the multiple flow-regulating channels formed by the multiple flow-regulating structures, preventing the cooling medium from directly flowing into the receiving cavity and forming transverse eddies. This allows the cooling medium to contact the heat exchange structure through the flow-regulating channels, ensuring reliable heat exchange between the cooling medium and the heat exchange structure. Meanwhile, the flow-blocking section of the slow-flow structure can collide with the cooling medium, further slowing down the flow rate of the cooling medium. This allows the cooling medium to have sufficient contact with the heat exchange structure, increasing the heat exchange area between the cooling medium and the heat exchange structure, improving heat exchange efficiency, and reducing the temperature of the cooling medium. This ensures the cooling effect of the cooling medium and solves the problem of poor cooling performance in existing water tank evaporators. Furthermore, the slow-flow channels formed around adjacent slow-flow structures simplify the formation of these channels, facilitating processing and installation.
