Description

Technical Field

[0001] This application relates to the technical field of cooling, and more specifically, to a cooling device and a cooling method. Background Technology

[0002] During product repair or manufacturing, it is sometimes necessary to heat a certain part of the product. The heat generated can be transferred along the product to other parts, which can easily cause the corresponding part of the product to deform or components to desolder, resulting in a low product yield. Summary of the Invention

[0003] Embodiments of this application provide a cooling device for blowing air onto a product to lower the product temperature, thereby improving product yield.

[0004] The cooling device includes a cooling component, a sealing component, a heat exchange assembly, a blower, a first temperature sensing component, and a control component. The cooling component has a cooling end. The sealing component has a sealed cavity, an air inlet, and an air outlet; the air inlet connects the sealed cavity to the outside of the sealed cavity, and the air outlet connects the sealed cavity to the outside of the sealed cavity. The heat exchange assembly is connected to the cooling end of the cooling component and is at least partially located within the sealed cavity. The blower is configured to blow gas from the sealed cavity out through the air outlet. The first temperature sensing component is disposed on the sealing component and configured to detect the temperature inside the sealed cavity. Both the first temperature sensing component and the blower are electrically connected to the control component. When the first temperature sensing component detects that the temperature inside the sealed cavity has dropped to a predetermined temperature, the control component controls the blower to operate.

[0005] In the above embodiments, the cooling device uses a cooling component to lower the temperature of the cooling end of the cooling component. Then, the gas in the sealed cavity exchanges heat with the cooling end through a heat exchange component, thereby lowering the temperature of the gas in the sealed cavity. When the first temperature detection component detects that the temperature inside the sealed cavity has dropped to a predetermined temperature, the control component controls the blower to operate, so that the gas outside the sealed cavity flows into the sealed cavity through the air inlet, and at the same time, the low-temperature gas inside the sealed cavity is blown out through the air outlet and blown toward the product to cool the product, thereby keeping the product in a low-temperature state, reducing the probability of defects such as heat deformation or component desoldering, and thus improving the product yield.

[0006] In some embodiments of this application, the heat exchange assembly includes a heat exchange tube, a heat exchange element, a heat exchange drive, a first connecting pipe, a second connecting pipe, and a third connecting pipe. The heat exchange tube is disposed within a sealed cavity and has a first end and a second end. The heat exchange element is connected to the cooling end of a cooling element, and is hollow internally with an inlet and an outlet, both of which communicate with the interior of the heat exchange element. The heat exchange drive has an inlet and an outlet; the first connecting pipe connects the first end and the inlet; the second connecting pipe connects the outlet and the inlet; and the third connecting pipe connects the outlet and the second end. The heat exchange drive is configured to drive the medium within the first connecting pipe to flow to the second connecting pipe.

[0007] In the above embodiments, after the cooling end of the refrigeration component lowers the temperature of the medium inside the heat exchanger, the heat exchange drive component directs the medium in the first connecting pipe to the second connecting pipe, thereby allowing the medium in the second connecting pipe to flow from the inlet to the interior of the heat exchanger, so that the low-temperature medium in the heat exchanger flows from the outlet through the third connecting pipe to the heat exchange tube; the low-temperature medium flowing into the heat exchange tube exchanges heat with the air in the sealed cavity through the heat exchange tube, thereby lowering the temperature of the gas in the sealed cavity, thus achieving the effect of cooling the sealed cavity.

[0008] In some embodiments of this application, the cooling device further includes a second temperature detection element electrically connected to the control element, and the second temperature detection element is configured to detect the temperature on one side of the air outlet located in the sealed cavity.

[0009] In the above embodiments, the controller automatically controls the operating status of the cooling component and the blower based on the temperature value measured by the second temperature sensor, thereby improving the accuracy of temperature control of the air blown out from the air outlet.

[0010] In some embodiments of this application, the cooling device further includes an airflow detection element electrically connected to the control element, and the airflow detection element is configured to detect the airflow at the air outlet.

[0011] In the above embodiments, the control unit automatically controls the operating state of the blower based on the value measured by the air volume detection unit, and can automatically adjust the air volume of the air outlet, thereby helping to keep the air volume of the air outlet stable.

[0012] Embodiments of this application also provide a cooling method that utilizes the aforementioned cooling device. The cooling method includes:

[0013] Set the first temperature threshold.

[0014] Start the heat exchange components and refrigeration components.

[0015] Detect the temperature inside the sealed cavity.

[0016] Compare the temperature inside the sealed cavity with the first temperature threshold.

[0017] When the temperature inside the sealed cavity is lower than the first temperature threshold, the blower is activated.

[0018] In the above embodiments, the heat exchange components and cooling components are activated to lower the temperature of the gas inside the sealed cavity. The measured temperature data inside the sealed cavity is defined as the cavity temperature. The control component can only activate the blower when the cavity temperature is lower than a first temperature threshold. This helps ensure that the temperature of the air blown out of the outlet meets the expected requirements, thereby reducing the probability that the temperature of the air blown out of the outlet is higher than the expected temperature, resulting in a poor cooling effect on the product.

[0019] In some embodiments of this application, the cooling method further includes:

[0020] Set a second temperature threshold.

[0021] The temperature of the air outlet located on the side of the sealed cavity is detected.

[0022] Compare the temperature on one side of the air outlet located in the sealed cavity with the second temperature threshold.

[0023] When the temperature on the side of the air outlet located in the sealed cavity is greater than or equal to the second temperature threshold, the blower is turned off and / or a prompt message is generated to prompt the product to pause heating.

[0024] In the above embodiments, the temperature data measured at the air outlet on one side of the sealed cavity is defined as the air outlet temperature. When the air outlet temperature is greater than or equal to the second temperature threshold, the temperature of the gas blown out from the air outlet is too high, making it difficult to achieve the effect of cooling the product. At this time, by turning off the blower, the gas in the sealed cavity is allowed to fully contact the heat exchange tube, so that the temperature inside the sealed cavity is further reduced to the predetermined temperature, allowing the control unit to restart the blower. Alternatively, a prompt message can be generated when the blower is running or stopped to remind the operator to pause the heating of the product.

[0025] In some embodiments of this application, the cooling method further includes:

[0026] Set a third temperature threshold and a fourth temperature threshold, where the fourth temperature threshold is less than the third temperature threshold.

[0027] The temperature of the air outlet located on the side of the sealed cavity is detected.

[0028] Compare the temperature of the air outlet on one side of the sealed cavity with the third temperature threshold.

[0029] Compare the temperature of the air outlet on one side of the sealed cavity with the fourth temperature threshold.

[0030] When the temperature on the side of the air outlet located in the sealed cavity is greater than or equal to the third temperature threshold, the air volume of the air outlet is reduced and / or the cooling power of the refrigeration component is increased. When the temperature on the side of the air outlet located in the sealed cavity is less than the fourth temperature threshold, the air volume of the air outlet is increased and / or the cooling power of the refrigeration component is decreased.

[0031] In the above embodiments, the measured temperature data of the air outlet located on one side of the sealed cavity is defined as the air outlet temperature. When the air outlet temperature is greater than or equal to the third temperature threshold, the contact time between the gas in the sealed cavity and the heat exchange tube is prolonged by reducing the air volume at the air outlet, thereby improving the heat exchange efficiency between the gas in the sealed cavity and the heat exchange tube, and thus reducing the temperature of the gas in the sealed cavity and the gas blown out from the air outlet. Alternatively, when the air outlet temperature is greater than or equal to the third temperature threshold, the cooling power of the cooling element can be increased to reduce the temperature of the medium in the heat exchange tube, thereby reducing the gas temperature in the sealed cavity and the temperature of the gas blown out from the air outlet.

[0032] Similarly, when the blowing temperature is below the fourth temperature threshold, the contact time between the gas in the sealed cavity and the heat exchange tube can be shortened by increasing the airflow from the blowing port, or the temperature of the medium in the heat exchange tube can be increased by reducing the cooling power of the cooling components. This, in turn, increases the temperature of the gas in the sealed cavity, thereby raising the temperature of the gas blown out from the outlet. As described above, automatic temperature regulation of the gas blown out from the outlet can be achieved, thus helping to maintain a constant temperature for the gas blown out from the outlet.

[0033] In some embodiments of this application, the cooling method further includes:

[0034] Set the first air outlet threshold.

[0035] Detect the air volume at the air outlet.

[0036] Compare the air volume at the air outlet with the first air outlet threshold.

[0037] When the air volume at the air outlet is less than the first air outlet threshold, the blower is turned off and / or a prompt message is generated to remind the user to pause the heating of the product.

[0038] In the above embodiments, the measured air volume data of the air outlet is defined as the outlet air volume. When the outlet air volume is less than the first outlet threshold, the flow rate of the gas blown out of the air outlet is relatively low, making it difficult for the gas to come into contact with the product or to achieve the effect of cooling the product. At this time, by turning off the blower, energy loss can be reduced and waste can be minimized. Alternatively, a prompt message can be generated to remind the operator to pause the heating of the product.

[0039] In some embodiments of this application, the cooling method further includes:

[0040] Set a second air outlet threshold and a third air outlet threshold, where the second air outlet threshold is greater than the third air outlet threshold.

[0041] Detect the air volume at the air outlet.

[0042] Compare the air volume of the air outlet and the second air outlet threshold.

[0043] Compare the air volume of the air outlet with the third air outlet threshold.

[0044] When the air volume at the air outlet is greater than or equal to the second air outlet threshold, the air volume at the air outlet is reduced; when the air volume at the air outlet is less than the third air outlet threshold, the air volume at the air outlet is increased.

[0045] In the above embodiments, the measured airflow data of the air outlet is defined as the outlet airflow. When the outlet airflow is greater than or equal to the second outlet airflow threshold, the outlet airflow is reduced. When the outlet airflow is less than the third outlet airflow threshold, the outlet airflow is increased, thereby helping to keep the outlet airflow within a fixed range and improving the stability of the outlet airflow.

[0046] In some embodiments of this application, the step of starting the heat exchange assembly and the cooling component includes:

[0047] Detect the capacity of the heat exchange medium within the heat exchange assembly.

[0048] Compare the capacity of the heat exchange medium in the heat exchange component with the preset capacity threshold.

[0049] When the capacity of the heat exchange medium in the heat exchange component is greater than or equal to a preset capacity threshold, the heat exchange component and the refrigeration unit are activated. When the capacity of the heat exchange medium in the heat exchange component is less than the preset capacity threshold, an alarm message is generated to prompt the replenishment of heat exchange medium.

[0050] In the above embodiments, by detecting whether the heat exchange medium is sufficient, the operator is reminded to replenish the heat exchange medium when it is insufficient, thereby ensuring that the heat exchange medium is sufficient when the cooling device is running, thus ensuring the heat exchange efficiency and the cooling efficiency of the cooling device.

[0094] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0095] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0096] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0097] The term “and / or” as used herein includes any and all combinations of one or more of the related listed items.

[0098] Furthermore, the terms “first,” “second,” “third,” “fourth,” etc., are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance.

[0099] Currently, electronic products are becoming increasingly sophisticated, and PCBs (Printed Circuit Boards) are becoming thinner. For PCB repair, the heat generated during component repair can transfer to the other side (back side) of the PCB due to its thinness, causing the temperature on the back side of the component to reach the melting point of solder, resulting in component failure and increasing the difficulty of repair. A related technique involves using a cold air gun to cool the area of ​​the PCB that needs cooling. The cold air is at room temperature (typically 24 degrees Celsius). However, due to technical limitations, this method can generally only achieve a maximum temperature difference of 12 degrees Celsius, and the temperature on the back side remains within the melting point of solder.

[0100] Embodiments of this application provide a cooling device, including a cooling component, a sealing component, a heat exchange assembly, a blower, a first temperature detection component, and a control component. The cooling component has a cooling end. The sealing component is provided with a sealing cavity, an air inlet, and an air outlet. The air inlet connects the sealing cavity to the outside of the sealing cavity, and the air outlet connects the sealing cavity to the outside of the sealing cavity. The heat exchange assembly is connected to the cooling end of the cooling component and is at least partially located within the sealing cavity. The blower is configured to blow gas from the sealing cavity out through the air outlet. The first temperature detection component is disposed on the sealing component and configured to detect the temperature inside the sealing cavity. The first temperature detection component, the cooling component, and the blower are all electrically connected to the control component. When the first temperature detection component detects that the temperature inside the sealing cavity has dropped to a predetermined temperature, the control component controls the blower to operate, so that the gas inside the sealing cavity is blown out through the air outlet.

[0101] The cooling component lowers the temperature of its cooling end. Then, the gas inside the sealed cavity exchanges heat with the cooling end through the heat exchange component, further lowering the temperature of the gas inside the sealed cavity. When the first temperature detection component detects that the temperature inside the sealed cavity has dropped to a predetermined temperature, the control component controls the blower to operate, allowing gas from outside the sealed cavity to flow into the sealed cavity through the air inlet. At the same time, the low-temperature gas inside the sealed cavity is blown out through the air outlet and directed towards the product to cool it down. This keeps the product in a low-temperature state, reducing the probability of defects such as heat deformation or component desoldering.

[0102] When the embodiments of this application are applied to PCB repair, by setting a predetermined temperature, such as 7 degrees Celsius, the internal temperature of the sealed cavity reaches the predetermined temperature. Then, the low-temperature gas in the sealed cavity is blown out of the air outlet and blown towards the back of the PCB by the blower. In this way, the temperature of the components on the back of the PCB can be effectively reduced, so that the temperature difference between the front and back of the PCB reaches more than 27 degrees Celsius. At this time, the temperature of the back of the PCB is lower than the melting solder temperature, thereby reducing the probability of deformation or desoldering of the components on the back of the PCB when replacing components.

[0103] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0104] Reference Figure 1 and Figure 2 One embodiment of this application provides a cooling device 100. The cooling device 100 includes a cooling component 1, a sealing component 2, a heat exchange assembly 3, a blower 4, a first temperature detection component 5, and a control component (not shown in the figure). The cooling component 1 has a cooling end and a heat dissipation end. The sealing component 2 is provided with a sealing cavity 21, an air inlet 22, and an air outlet 23. The air inlet 22 connects to the sealing cavity 21 and the outside of the sealing cavity 21, and the air outlet 23 connects to the sealing cavity 21 and the outside of the sealing cavity 21. The heat exchange assembly 3 is connected to the cooling end and is at least partially located within the sealing cavity 21, and cools the gas within the sealing cavity 21. The blower 4 is installed at the air inlet 22 and configured to allow air to enter the sealing cavity 21 through the air inlet 22, so that the gas flows through the sealing cavity 21 and is blown out through the air outlet 23. The first temperature detection component 5 is disposed on the sealing component 2 and configured to detect the temperature within the sealing cavity 21. The first temperature detection component 5, the cooling component 1, and the blower 4 are all electrically connected to the control component.

[0105] The heat within the sealed cavity 21 is exchanged and cooled by the heat exchange components 3 located within the sealed cavity 21. After absorbing the heat from the sealed cavity 21, the heat exchange components 3 transfer the heat to the cooling end of the cooling element 1, and then the cooling end transfers the heat to the heat dissipation end, which then dissipates the heat, thereby lowering the temperature within the sealed cavity 21. When the first temperature sensor 5 detects that the temperature within the sealed cavity 21 has dropped to a predetermined temperature, the controller controls the blower 4 to operate, causing external gas to flow into the sealed cavity 21 through the air inlet 22 and be cooled within the sealed cavity 21. The cooled gas is then blown out through the air outlet 23. The gas blown out through the air outlet 23 can be used to cool the product, keeping it at a low temperature. When welding products, the gas blown out through the air outlet 23 can be directed towards the welding area to reduce the probability of product deformation due to heat or component detachment.

[0106] When this cooling device 100 is used for PCB repair, a predetermined temperature is set, for example, 7 degrees Celsius. Once the internal temperature of the sealed cavity 21 reaches this predetermined temperature, the blower 4 forces the low-temperature gas from the sealed cavity 21 out through the outlet 23 and onto the back of the PCB. This effectively reduces the temperature of the components on the back of the PCB, achieving a temperature difference of over 27 degrees Celsius between the front and back of the PCB. At this temperature, the back of the PCB is below the melting point of solder, thus reducing the probability of deformation or desoldering of the components on the back of the PCB during component replacement. In other embodiments, the predetermined temperature can be set to 3 degrees Celsius or 8 degrees Celsius. In still other embodiments, the predetermined temperature can be adjusted according to room temperature, as long as it effectively keeps the back of the PCB below the melting point of solder.

[0107] In some embodiments, the first temperature detection element 5 is a temperature sensor, and the first temperature detection element 5 is fixed inside the seal 2; the control element is a PLC. In other embodiments, the control element may be a microcontroller or other electrical components with the functions of receiving signals, processing signals, and outputting signals.

[0108] In some embodiments, the cooling element 1 is a semiconductor refrigeration chip, with its cooling end used for cooling and its heat dissipation end used for heat dissipation. In other embodiments, the cooling element 1 can be a compressor or other types of refrigeration structures.

[0109] In some embodiments, the sealing member 2 is a hollow shell, and a sealing cavity 21 is formed inside the sealing member 2. The gas in the sealing cavity 21 exchanges heat with the cooling end of the cooling member 1 through the heat exchange component 3, and the heat of the gas in the sealing cavity 21 is transferred to the heat dissipation end of the cooling member 1, thereby reducing the temperature of the gas in the sealing cavity 21.

[0110] In some embodiments, the cooling device 100 further includes a heat sink 6, which is connected to the heat dissipation end of the cooling component 1. In some embodiments, the heat sink 6 includes a heat sink plate 61 and a plurality of heat sink fins 62, which are sequentially spaced on the heat sink plate 61 and integrally formed with the heat sink plate 61. The heat sink plate 61 is connected to the heat dissipation end of the cooling component 1. The heat from the heat dissipation end is transferred to the heat sink fins 62 and then to the air via the heat sink plate 61.

[0111] In some embodiments, the sealing member 2 is welded and fixed with an air inlet pipe 24 and an air outlet pipe 25, the interiors of both the air inlet pipe 24 and the air outlet pipe 25 communicating with the sealing cavity 21. The opening at the end of the air inlet pipe 24 away from the sealing member 2 forms an air inlet 22, and the opening at the end of the air outlet pipe 25 away from the sealing member 2 forms an air outlet 23. In other embodiments, the air inlet 22 and / or the air outlet 23 may be formed on the outer wall of the sealing member 2 and communicate with the sealing cavity 21.

[0112] In some embodiments, the blower 4 is a blower, and its outlet end is connected to the inlet pipe 24. The blower 4 is used to blow gas outside the sealed cavity 21 into the sealed cavity 21 through the inlet 22, and the gas inside the sealed cavity 21 is discharged through the outlet 23 and blown towards the part of the product that needs to be cooled. In other embodiments, the inlet end of the blower 4 can be connected to the outlet pipe 25 so that the blower 4 can draw gas from the sealed cavity 21 out through the outlet 23.

[0113] In some embodiments, the cooling device 100 further includes a second temperature sensor 7 electrically connected to the control element, the second temperature sensor 7 being configured to detect the temperature of the air outlet 23 on one side of the sealed cavity 21. In some embodiments, the second temperature sensor 7 is a temperature sensor, and the second temperature sensor 7 is fixed to the air outlet duct 25, with the detection end of the second temperature sensor 7 extending into the interior of the air outlet duct 25 to detect the temperature of the air outlet 23 on one side of the sealed cavity 21.

[0114] The control unit automatically controls the operating status of the cooling unit 1 and the blower unit 4 based on the temperature data measured by the second temperature detection unit 7, thereby improving the accuracy of temperature control of the air blown out from the air outlet 23.

[0115] In some embodiments, the cooling device 100 further includes an airflow detection element 8, which is electrically connected to the control element and configured to detect the airflow rate of the air outlet 23. In some embodiments, the airflow detection element 8 is an airflow sensor, which is connected to the air outlet duct 25, and the detection end of the airflow detection element 8 extends into the interior of the air outlet duct 25 to detect the outlet airflow rate of the gas blown out of the air outlet 23. In other embodiments, the airflow detection element 8 can be a wind speed sensor, which is used to detect the wind speed at the air outlet 23, and the airflow rate of the gas blown out of the air outlet 23 is obtained by calculating the product of the wind speed and the cross-sectional area of ​​the air outlet 23.

[0116] The control unit automatically controls the operation of the blower 4 based on the air volume data measured by the air volume detection unit 8, and can automatically adjust the air volume of the air outlet 23, thereby helping to keep the air volume blown out of the air outlet 23 constant.

[0117] In some embodiments, the heat exchange assembly 3 includes a heat exchange tube 31, a heat exchange element 32, a heat exchange drive 33, a first connecting pipe 34, a second connecting pipe 35, and a third connecting pipe 36. The heat exchange tube 31 is disposed within the sealed cavity 21 and has a first end 311 and a second end 312. The heat exchange element 32 is connected to the cooling end of the cooling element 1. The heat exchange element 32 is hollow and has an inlet 321 and an outlet 322, both of which communicate with the interior of the heat exchange element 32. The heat exchange drive 33 has an inlet 331 and an outlet 332. The first connecting pipe 34 connects the first end 311 and the inlet 331, the second connecting pipe 35 connects the outlet 332 and the inlet 321, and the third connecting pipe 36 connects the outlet 322 and the second end 312. The heat exchange drive 33 is configured to drive the medium in the first connecting pipe 34 to flow to the second connecting pipe 35. In some embodiments, the heat exchange medium used for heat exchange in the heat exchange tube 31 is a coolant, and the heat exchange drive 33 is a pump. In other embodiments, the heat exchange medium can be air.

[0118] After the cooling end of the cooling component 1 lowers the temperature of the medium inside the heat exchanger 32, the heat exchange drive component 33 directs the medium in the first connecting pipe 34 to the second connecting pipe 35, thereby allowing the medium in the second connecting pipe 35 to flow from the inlet 321 to the interior of the heat exchanger 32, so that the low-temperature medium in the heat exchanger 32 flows from the outlet 322 through the third connecting pipe 36 to the heat exchange tube 31; the low-temperature medium flowing into the heat exchange tube 31 exchanges heat with the air in the sealing cavity 21 through the heat exchange tube 31, thereby lowering the temperature of the gas in the sealing cavity 21, thus achieving the effect of cooling the sealing cavity 21.

[0119] In some embodiments, the heat exchange tubes 31 are arranged in a serpentine pattern within the sealing cavity 21 to increase the contact area between the heat exchange tubes 31 and the gas within the sealing cavity 21, thereby improving heat exchange efficiency. The first end 311 and the second end 312 of the heat exchange tubes 31 both extend to the outside of the seal 2. In other embodiments, the heat exchange tubes 31 may be arranged in a disc-like or spiral shape within the sealing cavity 21.

[0120] In some embodiments, the heat exchanger 32 is a hollow block, and the outer wall of the heat exchanger 32 is fixedly attached to the cooling end of the cooling element 1.

[0121] In some embodiments, the heat exchanger 32 is welded and fixed with an inlet pipe and an outlet pipe, the interiors of which communicate with the interior of the heat exchanger 32. The opening at the end of the inlet pipe away from the heat exchanger 32 is called an inlet port 321, and the opening at the end of the outlet pipe away from the heat exchanger 32 is called an outlet port 322. In other embodiments, the inlet port 321 and / or the outlet port 322 may be formed on the outer wall of the heat exchanger 32 and communicate with the interior of the heat exchanger 32.

[0122] In some embodiments, there are multiple cooling elements 1 and multiple heat exchange elements 32, and the multiple heat exchange elements 32 are connected in series through pipes, that is, the output port 322 of the heat exchange element 32 is connected to the input port 321 of another heat exchange element 32 through a pipe; the cooling end of each cooling element 1 is connected to at least one heat exchange element 32. In other embodiments, the multiple heat exchange elements 32 are connected in parallel through pipes, that is, the input ports 321 of the multiple heat exchange elements 32 are all connected to the second connecting pipe 35 through pipes, and the corresponding output ports 322 of the multiple heat exchange elements 32 are all connected to the third connecting pipe 36 through pipes. In other embodiments, there may be multiple cooling elements 1 and only one heat exchange element 32, and the heat exchange element 32 is connected to the cooling ends of the multiple cooling elements 1.

[0123] Reference Figure 3 In some embodiments, the heat exchange assembly 3 further includes a liquid storage tank 37 configured to contain the heat exchange medium. The input end 331 of the heat exchange drive 33 is connected to the first connecting pipe 34 via the liquid storage tank 37.

[0124] In some embodiments, the heat exchange drive 33 is located inside the storage tank 37, and the input end 331 of the heat exchange drive 33 is open and located below the liquid level of the heat exchange medium in the storage tank 37. One end of the first connecting pipe 34, away from the first end 311 of the heat exchange tube 31, extends into the storage tank 37. When the heat exchange drive 33 is in operation, it drives the heat exchange medium in the storage tank 37 to the second connecting pipe 35, while the heat exchange medium in the first connecting pipe 34 flows into the storage tank 37, thereby forming a circulating flow of the heat exchange medium.

[0125] In other embodiments, the heat exchange drive 33 can be disposed outside the liquid storage tank 37. The liquid storage tank 37 is connected to an inlet pipe and an outlet pipe, the interiors of which communicate with the interior of the liquid storage tank 37. The opening of the outlet pipe near the end of the liquid storage tank 37 is located below the liquid level of the heat exchange medium inside the liquid storage tank 37. The first connecting pipe 34 includes an input section and an output section, both of which are tubular. The input section connects the first end 311 and the inlet pipe, and the output section connects the outlet pipe and the input end 331 of the heat exchange drive 33. After the heat exchange drive 33 is started, the heat exchange medium in the liquid storage tank 37 can be sequentially drawn from the outlet pipe, the output section, and the interior of the heat exchange drive 33 to the second connecting pipe 35. At the same time, the heat exchange medium in the heat exchange tube 31 flows sequentially from the input section and the inlet pipe into the liquid storage tank 37.

[0126] In some embodiments, the cooling device 100 further includes a heat exchange medium detection element 9, which is electrically connected to the control element and configured to detect whether the heat exchange medium in the heat exchange assembly 3 is sufficient. In some embodiments, the heat exchange medium detection element 9 includes a liquid level sensor, is fixed to the liquid storage tank 37, and has its detection end located inside the liquid storage tank 37 to detect the position of the liquid level of the heat exchange medium in the liquid storage tank 37. When the liquid level of the heat exchange medium in the liquid storage tank 37 is lower than a predetermined position, it indicates that the heat exchange medium in the heat exchange assembly 3 is insufficient. In other embodiments, the liquid storage tank 37 may be omitted, and the heat exchange medium detection element 9 may be configured to detect structural members (such as...) at the highest position in the heat exchange assembly 3. Figure 2 The position of the liquid level of the heat exchange medium inside the heat exchange element 32).

[0127] In other embodiments, the heat exchange medium detection element 9 can be a flow rate sensor, which is fixedly connected to the second connecting pipe 35 to detect the flow rate of the heat exchange medium within the second connecting pipe 35. When the flow rate of the heat exchange medium within the second connecting pipe 35 is less than a predetermined threshold, it indicates that there is insufficient heat exchange medium in the heat exchange assembly 3 or that there is a blockage inside the heat exchange assembly 3.

[0128] Reference Figure 1 and Figure 2 In some embodiments, the cooling device 100 further includes a housing 10, with the cooling component 1, the sealing component 2, and the heat exchange assembly 3 all disposed inside the housing 10, and the air inlet 22 and the air outlet 23 located outside the housing 10. The housing 10 is used to install the cooling component 1, the sealing component 2, and the heat exchange assembly 3 and provides protection for them.

[0129] Reference Figure 2 In some embodiments, the outer side wall of the outer casing 10 is provided with heat dissipation holes 11, and the heat dissipation end of the cooling component 1 is disposed facing the heat dissipation holes 11. In some embodiments, the heat dissipation plate 61 is fixed to the inner wall of the outer casing 10, and the heat dissipation fins 62 are disposed facing the heat dissipation holes 11 so that the heat generated by the cooling component 1 can be dissipated to the outside of the outer casing 10.

[0130] In some other embodiments, the outer casing 10 may be omitted, and both the cooling component 1 and the heat exchange assembly 3 are connected to the sealing component 2.

[0131] Reference Figure 4 An embodiment of this application also provides a cooling method. The cooling method includes the following steps:

[0132] Step S201: Set the first temperature threshold.

[0133] In some embodiments, a first temperature threshold is input into the control unit via an input device connected to the control unit. In some embodiments, the input device is a button.

[0134] Step S202: Start the heat exchange components and refrigeration components.

[0135] Combination Figure 2 In some embodiments, the heat exchange assembly 3 and the cooling component 1 are activated by a control unit. It is understood that in some embodiments, the heat exchange drive 33 of the heat exchange assembly 3 is activated by a control unit to drive the flow of the heat exchange medium, so that the gas in the sealed cavity 21 can exchange heat with the cooling end of the cooling component 1 through the heat exchange medium, thereby reducing the temperature inside the sealed cavity 21.

[0136] Step S203: Detect the temperature inside the sealed cavity.

[0137] Combination Figure 2 In some embodiments, the control unit obtains the temperature data inside the sealed cavity 21 by reading the data detected by the first temperature detection element 5. For ease of description, the temperature data inside the sealed cavity 21 read by the control unit is defined as the cavity temperature.

[0138] Step S204: Compare the temperature inside the sealed cavity with the first temperature threshold.

[0139] The controller controls the operation of the blower by comparing the cavity temperature with a first temperature threshold. In some embodiments, when the cavity temperature is lower than the first temperature threshold, the controller activates the blower to keep it running. It is understood that when the cavity temperature is lower than the first temperature threshold and the blower is running, the controller keeps the blower in its current state.

[0140] The blower can only be activated when the temperature inside the cavity is lower than the first temperature threshold. This helps ensure that the temperature of the air blown out of the outlet meets the expected requirements, thereby reducing the probability that the temperature of the air blown out of the outlet is higher than the expected temperature, resulting in a poor cooling effect on the product.

[0141] For step S201, in some other embodiments, the input device may also be a keyboard, a touch screen, or other structural components capable of inputting data into the control unit.

[0142] Combination Figure 5 In some embodiments, step S202 includes the following specific steps S2021 to S2022.

[0143] Step S2021: Detect the capacity of the heat exchange medium in the heat exchange assembly.

[0144] Combination Figure 3In some embodiments, the control unit obtains the heat exchange medium capacity data within the heat exchange assembly 3 by reading data measured by the heat exchange medium detection unit 9. For ease of description, the capacity data of the heat exchange medium within the heat exchange assembly 3 read by the control unit is defined as the medium capacity.

[0145] Step S2022: Compare the capacity of the heat exchange medium in the heat exchange component with the capacity threshold.

[0146] In some embodiments, the capacity threshold is preset within the control during programming.

[0147] In some embodiments, when the medium capacity is greater than or equal to a preset capacity threshold, the controller activates the heat exchange assembly and the refrigeration assembly, keeping both the heat exchange drive and the refrigeration assembly operational. In some embodiments, when the medium capacity is less than the preset capacity threshold, the controller generates an alarm message to prompt the operator to replenish the heat exchange medium.

[0148] In some embodiments, the control unit is electrically connected to a buzzer, and alarm information is output in the form of an audible sound from the buzzer to prompt the operator to stop heating the product.

[0149] In some embodiments, for step S2021, a separate level detector can be used to detect the liquid level in the storage tank. This level detector is electrically connected to the control unit so that the control unit can read the capacity data of the heat exchange medium through the level detector.

[0150] In some embodiments, for step S2022, a capacity threshold can be input into the control unit via an input device connected to the control unit. The input device can be a button, keyboard, touchscreen, or other structural component capable of inputting data into the control unit.

[0151] In some embodiments, for step S2022, the control unit may be electrically connected to a display, and the alarm information may be displayed on the display. In other embodiments, the alarm information may also be displayed in the form of vibration or light.

[0152] In some embodiments, for step S202, after confirming that the heat exchange medium is sufficient, the heat exchange drive of the refrigeration component and the heat exchange assembly can also be started by manually switching on the switch.

[0153] In some embodiments, for step S203, a separate temperature detector can be used to detect the temperature inside the sealed cavity 21. This temperature detector is electrically connected to the control unit so that the control unit can read the corresponding temperature data through the temperature detector.

[0154] Regarding step S204, in some embodiments, when the cavity temperature is greater than or equal to a first temperature threshold, the control unit shuts off the blower, keeping the blower in a closed state. It can be understood that when the cavity temperature is greater than or equal to the first temperature threshold and the blower is in a closed state, the control unit keeps the blower in its current state.

[0155] In some embodiments, steps S201 to S204 are performed sequentially. In other embodiments, step S202 may be performed before step S201.

[0156] Reference Figure 6 Another embodiment of this application provides a cooling method, which includes the following steps:

[0157] Step S301: Set the first temperature threshold.

[0158] In some embodiments, a detailed description of step S301 can be found in [reference needed]. Figure 4 Step S201 in the provided embodiment.

[0159] Step S302: Set the second temperature threshold.

[0160] In some embodiments, a second temperature threshold can be input into the control unit via an input device connected to the control unit. In some embodiments, the input device is a button.

[0161] In some embodiments, the first temperature threshold is less than the second temperature threshold.

[0162] Step S303: Start the heat exchange components and refrigeration components.

[0163] Step S304: Detect the temperature inside the sealed cavity.

[0164] Step S305: Compare the temperature inside the sealed cavity with the first temperature threshold.

[0165] In some embodiments, the detailed description of steps S303 to S305 refers to... Figure 4 Steps S202 to S204 in the provided embodiments.

[0166] Step S306: Detect the temperature on the side of the air outlet located in the sealed cavity.

[0167] Combination Figure 2 In some embodiments, the controller obtains the temperature data of the air outlet 23 located on one side of the sealed cavity 21 by reading the data detected by the second temperature sensor 7. For ease of description, the temperature data of the air outlet 23 located on one side of the sealed cavity 21 read by the controller is defined as the air outlet temperature.

[0168] In some embodiments, step S306 is performed when the blower is in operation.

[0169] Step S307: Compare the temperature on one side of the air outlet located in the sealed cavity with the second temperature threshold.

[0170] In some embodiments, when the outlet air temperature is greater than or equal to a second temperature threshold, the control unit shuts off the blower and generates a prompt message to keep the blower in the off state. The prompt message is used to prompt the product to pause heating.

[0171] In some embodiments, the control unit is electrically connected to a buzzer, and the prompt information is output in the form of an audible sound from the buzzer to prompt the operator to pause the heating of the product.

[0172] When the outlet air temperature is greater than or equal to the second temperature threshold, the temperature of the gas blown out from the outlet is too high, making it difficult to cool the product. In this case, by turning off the blower, the gas in the sealed cavity can be made to fully contact the heat exchange tube, so that the temperature inside the sealed cavity can be further reduced. A prompt message can also be generated when the blower is running or stopped to remind the operator to stop heating the product.

[0173] For step S302, in some other embodiments, the input device may be a keyboard, a touch screen, or other structural components capable of inputting data into the control unit.

[0174] For step S302, in some other embodiments, the first temperature threshold may be equal to the second temperature threshold.

[0175] In some embodiments, for step S306, a separate temperature detector can be used to detect the temperature of the air outlet located on the side of the sealed cavity. This temperature detector is electrically connected to the control unit so that the control unit can read the corresponding temperature data through the temperature detector.

[0176] For step S307, in some other embodiments, when the outlet air temperature is greater than or equal to a second temperature threshold, the control unit shuts off the blower or generates a prompt message.

[0177] In some embodiments, for step S307, the control unit may be electrically connected to a display, and the prompt information may be displayed on the display. In other embodiments, the prompt information may also be displayed in the form of vibration or light.

[0178] For step S307, in some embodiments, when the outlet air temperature is less than the second temperature threshold, the control unit keeps the blower in operation.

[0179] In some embodiments, steps S301 to S307 are executed sequentially. In other embodiments, step S302 may be executed before step S301. In other embodiments, step S303 may be executed before step S301. In other embodiments, steps S301 to S303 may be executed simultaneously.

[0180] Reference Figure 7 Another embodiment of this application provides a cooling method, which includes the following steps:

[0181] Step S401: Set the first temperature threshold.

[0182] In some embodiments, a detailed description of step S401 can be found in [reference needed]. Figure 4 Step S201 in the provided embodiment.

[0183] Step S402: Set the third temperature threshold and the fourth temperature threshold.

[0184] In some embodiments, a third temperature threshold and a fourth temperature threshold can be input into the control unit via an input device connected to the control unit. In some embodiments, the input device is a button.

[0185] In some embodiments, the fourth temperature threshold is less than the third temperature threshold and greater than the first temperature threshold.

[0186] Step S403: Start the heat exchange components and refrigeration components.

[0187] Step S404: Detect the temperature inside the sealed cavity.

[0188] Step S405: Compare the temperature inside the sealed cavity with the first temperature threshold.

[0189] In some embodiments, the specific description of steps S403 to S405 is as follows: Figure 4 Steps S202 to S204 in the provided embodiments.

[0190] Step S406: Detect the temperature on the side of the air outlet located in the sealed cavity.

[0191] In some embodiments, a detailed description of step S406 is provided below. Figure 5 In the embodiment provided, step S306 is used to define the temperature data of the air outlet located on one side of the sealed cavity read by the control unit as the air outlet temperature.

[0192] Step S407: Compare the temperature on the side of the air outlet located in the sealed cavity with the third temperature threshold.

[0193] In some embodiments, when the outlet air temperature is greater than or equal to a third temperature threshold, the control component reduces the airflow at the outlet. In some embodiments, the airflow at the outlet is reduced by decreasing the blower power of the blower component.

[0194] Step S408: Compare the temperature on one side of the air outlet located in the sealed cavity with the fourth temperature threshold.

[0195] In some embodiments, when the outlet air temperature is less than a fourth temperature threshold, the control increases the airflow at the outlet. In some embodiments, the airflow at the outlet is increased by increasing the blowing power of the blower.

[0196] In some embodiments, steps S406 to S408 are performed when the blower is in operation.

[0197] When the outlet air temperature is greater than or equal to the third temperature threshold, the contact time between the gas in the sealed cavity and the heat exchange tube is prolonged by reducing the airflow from the outlet, thereby improving the heat exchange efficiency between the gas in the sealed cavity and the heat exchange tube, and thus reducing the temperature of the gas in the sealed cavity and the gas blown out from the outlet. When the blowing air temperature is less than the fourth temperature threshold, the contact time between the gas in the sealed cavity and the heat exchange tube is shortened by increasing the airflow from the outlet, thereby reducing the heat exchange efficiency between the gas in the sealed cavity and the heat exchange tube, and thus increasing the temperature of the gas in the sealed cavity and the gas blown out from the outlet. As described above, the temperature of the gas blown out from the outlet can be automatically adjusted, which helps to keep the temperature of the gas blown out from the outlet constant.

[0198] In some embodiments, for step S402, the input device may be a keyboard, a touch screen, or other structural components capable of inputting data into the control unit.

[0199] For step S402, in some other embodiments, the fourth temperature threshold may be equal to the first temperature threshold.

[0200] In some embodiments, for step S407, when the outlet air temperature is greater than or equal to a third temperature threshold, the control unit increases the cooling power of the cooling element. This is achieved by increasing the current to the cooling element, thereby increasing its cooling power.

[0201] In some embodiments, for step S407, when the outlet air temperature is greater than or equal to a third temperature threshold, the control reduces the outlet air volume and increases the cooling power of the cooling element.

[0202] For step S407, in some embodiments, when the outlet air temperature is less than the third temperature threshold, the control unit keeps both the blower and the cooling unit in their current operating state.

[0203] In some embodiments, for step S408, when the outlet air temperature is less than a fourth temperature threshold, the control unit may reduce the cooling power of the cooling unit. This is achieved by reducing the current to the cooling unit, thereby reducing its cooling power.

[0204] In some embodiments, for step S408, when the outlet air temperature is less than the fourth temperature threshold, the control increases the outlet air volume and reduces the cooling power of the cooling element.

[0205] For step S408, in some embodiments, when the outlet air temperature is greater than or equal to a fourth temperature threshold, the control unit keeps both the blower and the cooling unit in their current operating state.

[0206] Besides adjusting the blower power to regulate the airflow at the outlet, as described above, in some embodiments, a regulating valve can be installed at the outlet. The airflow at the outlet is adjusted by controlling the opening of the regulating valve; specifically, increasing the opening of the regulating valve increases the airflow at the outlet, while decreasing the opening of the regulating valve decreases the airflow at the outlet. In another embodiment, the airflow at the outlet can also be adjusted using other methods.

[0207] Besides adjusting the cooling power of the cooling element by changing its current, in other embodiments, the cooling power can be adjusted by changing its voltage. Specifically, decreasing the voltage decreases the cooling power, while increasing the voltage increases the cooling power. In embodiments with multiple cooling elements, the cooling power can also be adjusted by controlling the number of cooling elements in operation; the more cooling elements in operation, the greater the overall cooling power. In this case, the "cooling power of the cooling elements" in the above steps should be understood as the overall cooling power of the mechanism formed by multiple cooling elements.

[0208] When the outlet air temperature is greater than or equal to the third temperature threshold, the cooling power of the refrigeration unit is increased to reduce the temperature of the medium inside the heat exchange tubes, thereby reducing the gas temperature inside the sealed cavity and ultimately lowering the temperature of the gas blown out of the outlet. When the outlet air temperature is less than the fourth temperature threshold, the cooling power of the refrigeration unit is decreased to increase the temperature of the medium inside the heat exchange tubes, thereby increasing the gas temperature inside the sealed cavity and ultimately raising the temperature of the gas blown out of the outlet. This allows for automatic temperature regulation of the gas blown out of the outlet, helping to maintain a constant temperature.

[0209] In some embodiments, the value of each increase or decrease in air volume and the value of each increase or decrease in cooling power are preset in the controller, for example, during programming.

[0210] In some embodiments, steps S401 to S408 are executed sequentially. In other embodiments, step S402 may be executed before step S401. In other embodiments, step S403 may be executed before step S401. In other embodiments, steps S401 to S403 may be executed simultaneously.

[0226] Step S511: Compare the air volume of the air outlet with the first air outlet threshold.

[0227] In some embodiments, when the outlet air volume is less than a first outlet air threshold, the control unit shuts off the blower and generates a prompt message to prompt the product to pause heating.

[0228] In some embodiments, the control unit is electrically connected to a buzzer, and the prompt information is output in the form of an audible sound from the buzzer to prompt the operator to pause the heating of the product.

[0229] In some embodiments, for step S503, a first air outlet threshold can be input into the control unit via an input device connected to the control unit. The input device can be a button, keyboard, touchscreen, or other structural component capable of inputting data into the control unit.

[0230] In some embodiments, for step S510, an additional airflow detector can be used to detect the airflow at the outlet. This airflow detector is electrically connected to the control unit so that the control unit can obtain the airflow data at the outlet through the airflow detector.

[0231] For step S511, in some other embodiments, when the outlet air volume is less than the first outlet air threshold, the control unit shuts off the blower or generates a prompt message.

[0247] Step S607: Compare the air volume of the air outlet with the second air outlet threshold.

[0248] In some embodiments, when the outlet air volume is greater than or equal to a second outlet air threshold, the outlet air volume is reduced. In some embodiments, the control component reduces the outlet air volume by reducing the blower power of the blower.

[0249] Step S608: Compare the air volume of the air outlet with the third air outlet threshold.

[0250] In some embodiments, when the outlet air volume is less than the third outlet air threshold, the outlet air volume is increased. In some embodiments, the control unit increases the outlet air volume by increasing the blowing power of the blower.

[0251] When the outlet air volume is greater than or equal to the second outlet air threshold, the outlet air volume is reduced. When the outlet air volume is less than the third outlet air threshold, the outlet air volume is increased, which helps to keep the outlet air volume within a fixed range and improve the stability of the outlet air volume.

[0252] In some embodiments, for step S602, a second air outlet threshold and a third air outlet threshold can be input into the control unit via an input device connected to the control unit. The input device can be a button, a keyboard, a touch screen, or other structural component capable of inputting data into the control unit.

[0253] For step S607, in some embodiments, when the outlet air volume is less than the second outlet air threshold, the control element keeps the blower in its current operating state.

[0254] For step S608, in some embodiments, when the outlet air volume is greater than or equal to the third outlet air threshold, the control element keeps the blower in its current operating state.
