[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0051] The embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0052] refer to Figures 1 to 5The embodiment of the present application discloses a drying device for heating a to-be-dried object to achieve a drying process, wherein the to-be-dried object may be a battery. In this case, the drying device may be used to dry the ink on the surface of the battery. Of course, the drying device may also be applied to other scenarios, which are not specifically limited here. The disclosed drying device includes a housing 10, an evaporator 20, a condenser 30, and a compressor 40.

[0053] The housing 10 is a basic component, which can provide a mounting and bearing foundation for the evaporator 20, the condenser 30, the compressor 40, etc. In some embodiments, the evaporator 20, the condenser 30, and the compressor 40 can all be arranged in the housing 10, so as to ensure the stability of each component through the installation and bearing of the housing 10; in addition, the housing 10 can also play a certain protective role for each component to prevent the external environment from interfering with the operation of each component.

[0054] The housing 10 may have an inner cavity, and the evaporator 20 , the condenser 30 and the compressor 40 may all be disposed in the inner cavity of the housing 10 .

[0055] In order to overcome the problem of high energy consumption, the embodiment of the present application does not use a high-power heating tube to generate heat, but uses a refrigerant that can undergo phase change to generate heat through the phase change process of the refrigerant, thereby overcoming the problem of high power and high energy consumption of the heating tube. It should be noted here that the type of refrigerant can be the refrigerant of the air conditioner, of course, it can also be other types, which are not specifically limited here.

[0056] The evaporator 20 can be used to convert the refrigerant from a liquid state to a gaseous state. In an environment with a relatively low temperature (e.g., the temperature is lower than the boiling point of the refrigerant), the refrigerant can be in a liquid state, and in an environment with a relatively high temperature (e.g., the temperature is higher than the boiling point of the refrigerant), the refrigerant can be converted from a liquid state to a gaseous state, that is, the refrigerant absorbs heat and then evaporates. In the embodiment of the present application, the evaporator 20 can absorb heat from its surrounding environment, so that the refrigerant in the evaporator 20 absorbs heat, and when the temperature exceeds the boiling point of the refrigerant, the refrigerant is converted from a liquid state to a gaseous state.

[0057] In addition, the evaporator 20 may include a first inlet 21 and a first outlet 22, wherein the first inlet 21 may be used to receive liquid refrigerant so that the liquid refrigerant can enter the evaporator 20, and the first outlet 22 may be used to output gaseous refrigerant. It should be noted here that the specific structure of the evaporator 20 and its evaporation principle can refer to the prior art and will not be elaborated here.

[0058] The compressor 40 is used to pressurize the refrigerant. The compressor 40 may include an input port 41 and an output port 42, wherein the input port 41 is connected to the first outlet 22, so that the gaseous refrigerant formed after evaporation by the evaporator 20 can be discharged through the first outlet 22 and enter the compressor 40 through the input port 41. The gaseous refrigerant is pressurized by the compressor 40, thereby increasing the pressure of the gaseous refrigerant, and the temperature of the gaseous refrigerant after compression will also rise, so that after pressurization, a high-temperature and high-pressure gaseous refrigerant can be obtained and discharged through the output port 42.

[0059] It should be noted here that the gaseous refrigerant output from the output port 42 of the compressor 40 has a higher temperature and a higher pressure than the gaseous refrigerant output from the first outlet 22 of the evaporator 20, and can thus be regarded as a high-temperature and high-pressure gaseous refrigerant. The high temperature and high pressure here are relative high temperature and high pressure, not absolute high temperature and high pressure.

[0060] The condenser 30 (or heat exchanger) is used to change the refrigerant from gas to liquid. In the process of the refrigerant passing through the condenser 30, part of the heat is transferred to the air around the condenser 30, so that the air temperature rises. At the same time, the temperature of the refrigerant after releasing the heat is lower than the boiling point, so that the refrigerant changes from gas to liquid.

[0061] In addition, the condenser 30 may include a second inlet 31 and a second outlet 32, wherein the second inlet 31 is connected to the outlet 42, so that the high-temperature and high-pressure gaseous refrigerant formed after being pressurized by the compressor 40 can be discharged through the outlet 42 and enter the condenser 30 through the second inlet 31 for condensation treatment (i.e., heat exchange process). The temperature of the refrigerant after condensation is lower than the boiling point due to the release of heat, thereby causing the refrigerant to change from gas to liquid, and the liquid refrigerant can be discharged through the second outlet 32.

[0062] The second outlet 32 ​​is connected to the first inlet 21, so that the liquid refrigerant discharged through the second outlet 32 ​​can enter the evaporator 20 again through the first inlet 21 for evaporation. Such a cycle can make the refrigerant continuously change phase between gas and liquid, so that heat can be absorbed or released during the phase change process.

[0063] It should be noted here that the specific structure of the condenser 30 and its condensation principle can refer to the existing technology and will not be elaborated here.

[0064] Considering that a large amount of heat is released in the process of the refrigerant changing from a high-temperature and high-pressure gaseous form to a liquid form in the condenser 30, this process can be used to provide heat for the drying process of the parts to be dried. Based on this, the shell 10 in the embodiment of the present application can be used to collect the high-temperature gas that absorbs heat around the condenser 30, and the shell 10 can have an air outlet 11, which can be arranged corresponding to the condenser 30, for outputting the high-temperature gas after heat exchange through the condenser 30, so that the high-temperature gas can reach the surface of the parts to be dried, so as to facilitate the drying process thereof.

[0065] In the embodiment of the present application, the evaporator 20 can absorb the heat around it and transfer the heat to the liquid refrigerant, so that the liquid refrigerant absorbs heat and is converted into a gaseous refrigerant; under the compression action of the compressor 40, the gaseous refrigerant can be pressurized to obtain a high-temperature and high-pressure gaseous refrigerant; the heat in the high-temperature and high-pressure gaseous refrigerant can be transferred to the surrounding air through the condenser 30, and the high-temperature air formed after absorbing heat is output through the air outlet 11, so that the high-temperature air can be used to heat the parts to be dried, thereby achieving a drying effect. At the same time, the high-temperature and high-pressure gaseous refrigerant releases heat and is converted into a liquid refrigerant, and flows back to the evaporator 20 to evaporate again. In this cycle, the heat transfer during the process of the refrigerant changing from liquid to gas and from gas to liquid can achieve the heating effect of the air around the condenser 30, and finally the high-temperature gas formed after heating is used to heat the parts to be dried, thereby achieving a drying effect.

[0066] Compared with the method of using an electric oven for drying, the embodiment of the present application does not use a high-power heating tube to generate heat, but uses the principle of material phase change to generate heat, and there is no high power loss. Therefore, the drying device in the embodiment of the present application can save energy and reduce drying costs while ensuring the drying effect; and because the heat generated by the phase change of the material is limited, it will not cause the temperature to rise rapidly to hundreds of degrees, thereby effectively alleviating the problem of the device burning due to high temperature.

[0067] refer to Figure 5In some embodiments, the drying device may further include a first pipeline 51, a second pipeline 52, and a third pipeline 53. The first pipeline 51 is connected between the first outlet 22 and the input port 41, so that the gaseous refrigerant output from the first outlet 22 can be transported to the input port 41 through the first pipeline 51, and enter the compressor 40 through the input port 41 for compression; the second pipeline 52 is connected between the output port 42 and the second inlet 31, so that the high-temperature and high-pressure gaseous refrigerant output from the output port 42 can be transported to the second inlet 31 through the second pipeline 52, and enter the condenser 30 through the second inlet 31 for condensation; the third pipeline 53 is connected between the second outlet 32 ​​and the first inlet 21, so that the liquid refrigerant output from the second outlet 32 ​​can be transported to the first inlet 21 through the third pipeline 53, and enter the evaporator 20 again through the first inlet 21.

[0068] Optionally, sealed connections may be respectively achieved between the two ends of the first pipeline 51 and the first outlet 22 and the input port 41, between the two ends of the second pipeline 52 and the output port 42 and the second inlet 31, and between the two ends of the third pipeline 53 and the second outlet 32 ​​and the first inlet 21 to prevent refrigerant leakage. For example, a clamp connection, a flange connection, etc. may be used, as long as the sealing and stability of the connection can be ensured, and the specific form is not limited.

[0069] Continue to refer Figure 5 In some embodiments, the drying device may further include an expansion valve 60, which may play a throttling role, that is, after the liquid refrigerant passes through the throttling hole of the expansion valve 60, it forms a mist-like hydraulic refrigerant. In this way, the throttling effect of the expansion valve 60 can create conditions for the evaporation of the refrigerant.

[0070] The expansion valve 60 can also regulate the flow rate of the refrigerant entering the evaporator 20 to prevent the evaporator 20 from outputting liquid refrigerant due to excessive flow rate, and can also prevent the evaporation from being completed prematurely due to too small flow rate, thereby causing insufficient refrigeration. For example, the maximum processing capacity of the evaporator 20 for liquid refrigerant is M, and the flow rate of the liquid refrigerant entering the evaporator 20 is greater than M. In this case, a portion of the liquid refrigerant with a flow rate greater than M will not have time to evaporate in the evaporator 20 and will be directly output; or, the maximum processing capacity of the evaporator 20 for liquid refrigerant is M, and the flow rate of the liquid refrigerant entering the evaporator 20 is less than M. In this way, the evaporator 20 does not reach the highest efficiency, so that the evaporator 20 does not achieve the best refrigeration effect.

[0071] It should be noted here that the specific structure and working principle of the expansion valve 60 can refer to the existing technology and will not be elaborated here.

[0072] In the embodiment of the present application, the expansion valve 60 can be connected to the third pipeline 53; of course, the expansion valve 60 can also be connected between the third pipeline 53 and the first inlet 21. Regardless of which arrangement is adopted, as long as it can ensure that the refrigerant passes through the expansion valve 60 before entering the evaporator 20, so as to create conditions for evaporation.

[0073] In order to install the evaporator 20, the condenser 30, the compressor 40 and other components, the housing 10 may be provided with a first inner cavity 12 and a second inner cavity 13. Figures 1 to 3 As shown. The condenser 30 is arranged in the first inner cavity 12, the air outlet 11 is connected to the first inner cavity 12, and the air outlet 11 is arranged opposite to the condenser 30, so that when the refrigerant passes through the condenser 30, a large amount of heat is released, and the supply air in the first inner cavity 12 absorbs the heat released by the refrigerant, so that the air in the first inner cavity 12 is heated and converted into high-temperature gas, and the high-temperature gas can be discharged through the air outlet 11, so that the high-temperature gas can contact with the parts to be dried and dry them.

[0074] Exemplarily, the condenser 30 may be entirely disposed in the first inner cavity 12 , or may be partially disposed in the first inner cavity 12 , and the specific configuration may be selected based on actual working conditions.

[0075] In some more specific embodiments, the condenser 30 can be arranged in the first inner cavity 12 and located at the edge of the first inner cavity 12 and opposite to the air outlet 11. In this way, the distance between the condenser 30 and the air outlet 11 can be shortened, so that the heat dissipated by the condenser 30 can be discharged through the air outlet 11 along with the air, which can improve the heat dissipation efficiency to a certain extent.

[0076] The evaporator 20 and the compressor 40 can both be disposed in the second inner cavity 13, so that the evaporator 20 and the compressor 40 are separated from the condenser 30, thereby avoiding mutual interference and affecting the transmission of heat. Exemplarily, the evaporator 20 and the compressor 40 can both be disposed in the second inner cavity 13, so that the evaporator 20 and the compressor 40 can be surrounded by the walls of the housing 10, which can play a protective role to a certain extent and reduce the influence of the external environment on the operation of the evaporator 20 and the compressor 40.

[0077] refer to Figures 1 to 3In some embodiments, the drying device may further include a first fan 71, which is disposed on the side wall of the shell 10, and an exhaust port of the first fan 71 is connected to the first inner cavity 12. In this way, when the first fan 71 is running, air can be injected into the first inner cavity 12 through the exhaust port to increase the air pressure in the first inner cavity 12. At the same time, the air entering the first inner cavity 12 can absorb the heat dissipated by the condenser 30, thereby forming high-temperature gas; in addition, as the air pressure in the first inner cavity 12 increases, the high-temperature gas will be blown out through the air outlet 11, thereby increasing the blowing speed and flow rate of the high-temperature gas, and further allowing more high-temperature gas to contact the parts to be dried, which can improve the drying efficiency to a certain extent.

[0078] Exemplarily, the exhaust port of the first fan 71 may face the condenser 30 or may be offset from the condenser 30. Considering that the condenser 30 and the air outlet 11 are arranged opposite to each other, when the exhaust port faces the condenser 30, the exhaust port, the condenser 30 and the air outlet 11 are arranged in sequence, so that part of the air blown from the exhaust port to the condenser 30 will be directly discharged from the air outlet 11. In this case, the air may be blown out from the air outlet 11 before absorbing more heat, which will affect the drying efficiency to a certain extent.

[0079] Based on the above situation, in the embodiment of the present application, the exhaust port of the first fan 71 can be offset from the condenser 30, that is, not facing the condenser 30. In this case, the air discharged from the exhaust port of the first fan 71 first enters the first inner cavity 12, flows in the first inner cavity 12, and continuously absorbs the heat emitted by the condenser 30 during the flow, and then is discharged through the air outlet 11. Based on this, the time for the air to absorb heat in the first inner cavity 12 can be extended, so that the temperature of the air can be increased, so that the temperature of the high-temperature gas blown out through the air outlet 11 can be higher, thereby improving the drying efficiency.

[0080] In some embodiments, the first fan 71 may be a DC variable frequency fan, which can change the operating frequency. In addition, the drying device may further include a temperature sensor 81 , which is disposed at the air outlet 11 and is electrically connected to the first fan 71 .

[0081] Based on the above settings, the temperature at the air outlet 11 can be detected in real time by the temperature sensor 81 to prevent the temperature at the air outlet 11 from being too high or too low, thereby meeting the temperature requirements under different working conditions. It should be noted here that the higher the temperature at the air outlet 11, the higher the drying temperature; the lower the temperature at the air outlet 11, the lower the drying temperature.

[0082] Based on the above situation, when the temperature at the air outlet 11 is too high, the temperature sensor 81 can send a first signal to the first fan 71 to reduce the operating frequency of the first fan 71 and reduce the rotation speed of the first fan 71, thereby reducing the flow rate of the high-temperature gas blown out from the air outlet 11 to prevent the temperature at the air outlet 11 from being too high. For example, the preset drying temperature of the item to be dried is T0, and the temperature at the air outlet 11 is T1. When T1 is greater than T0 and the temperature difference exceeds 5°C, it is considered that the temperature at the air outlet 11 is too high. Of course, the temperature difference value can also be other values, which are not specifically limited here.

[0083] When the temperature at the air outlet 11 is too low, the temperature sensor 81 can send a second signal to the first fan 71 to increase the operating frequency of the first fan 71 and increase the rotation speed of the first fan 71, thereby increasing the flow rate of the high-temperature gas blown out from the air outlet 11 to prevent the temperature at the air outlet 11 from being too low. For example, the preset drying temperature of the item to be dried is T0, and the temperature at the air outlet 11 is T1. When T1 is less than T0 and the temperature difference exceeds 5°C, it is considered that the temperature at the air outlet 11 is too low. Of course, the temperature difference value can also be other values, which are not specifically limited here.

[0084] Based on the above settings, the embodiment of the present application can adjust the temperature at the air outlet 11 and improve the accuracy of temperature control, so as to adapt to more drying scenarios and improve the applicability of the drying device.

[0085] In addition, the temperature sensor 81 can also be electrically connected to the compressor 40, so that when it is detected that the temperature at the air outlet 11 is too high, the power of the compressor 40 can be reduced or the compressor 40 can be shut down; when it is detected that the temperature at the air outlet 11 is too low, the power of the compressor 40 can be increased, which can help improve the uniformity of temperature.

[0086] Continue to refer Figures 1 to 3 In some embodiments, the drying device may further include a second fan 72, which is disposed on the wall of the housing 10, and an air inlet of the second fan 72 is connected to the second inner cavity 13. Based on this configuration, the air in the second inner cavity 13 can be extracted by the second fan 72, so that the air with a relatively high outside temperature can continuously enter the second inner cavity 13, so that the evaporator 20 can absorb more heat, which is conducive to promoting the transformation of the refrigerant from liquid to gas.

[0087] It should be noted here that the wall of the shell 10 can also be provided with an air inlet, which is connected to the second inner cavity 13. In this way, as the second fan 72 discharges the lower temperature air generated in the second inner cavity 13 after heat exchange with the evaporator 20 to the outside of the second inner cavity 13, at the same time, the relatively high temperature air in the external environment can flow back to the second inner cavity 13 through the air inlet, thereby providing more heat for the evaporation process of the evaporator 20.

[0088] Among them, a partition 14 can be provided in the shell 10, which divides the inner cavity of the shell 10 into a first inner cavity 12 and a second inner cavity 13. Since the condenser 30 is located in the first inner cavity 12, and the evaporator 20 and the compressor 40 are both located in the second inner cavity 13, the condenser 30 can be separated from the evaporator 20 and the compressor 40 by the partition 14, thereby effectively preventing mutual interference between the devices.

[0089] In some embodiments, the evaporator 20 and the compressor 40 may be mounted on the partition 14 , so that the evaporator 20 and the compressor 40 are supported and fixed by the partition 14 to ensure the stability of the evaporator 20 and the compressor 40 .

[0090] Continue to refer Figures 1 to 3 In some embodiments, the drying device may further include a first support member 91 and a second support member 92. The first support member 91 and the second support member 92 are respectively connected to the bottom of the housing 10 and are arranged at intervals, so that the first support member 91, the second support member 92 and the bottom wall of the housing 10 together form a receiving space M for receiving the dried items. Based on this, when the dried items need to be dried, the dried items can be moved into the receiving space M.

[0091] Correspondingly, the air outlet 11 is arranged on the bottom wall of the shell 10 and is connected to the storage space M. In this way, the high-temperature gas formed by absorbing heat can be blown into the storage space M through the air outlet 11 and contact the parts to be dried in the storage space M, thereby drying them.

[0092] It should be noted here that since the first support member 91, the second support member 92 and the bottom wall of the shell 10 can limit the high-temperature gas, the high-temperature gas can more easily contact the object to be dried, which can reduce heat waste and improve drying efficiency to a certain extent.

[0093] In addition, a conveying mechanism may also pass through the accommodating space M, and the items to be dried may be transported to the accommodating space M for drying by the conveying mechanism, so as to improve the drying efficiency.

[0094] refer to Figure 2 and Figure 3In some embodiments, the drying device may further include a collecting container 1011, a water pump 1012 and a water level sensor 82, wherein the condenser 30 has a condensation water outlet, which is connected to the collecting container 1011, so that the condensation water generated during the condensation process of the condenser 30 can flow into the collecting container 1011 through the condensation water outlet for collection, thereby preventing the condensation water from being discharged at will.

[0095] After a period of time, the condensed water fills the collection container 1011, which may easily cause the condensed water to overflow. In this case, the water pump 1012 and the water level sensor 82 can be arranged in the collection container 1011, and the water pump 1012 is electrically connected to the water level sensor 82. In this way, when the water level sensor 82 detects that the condensed water in the collection container 1011 reaches a preset liquid level, a signal is sent to the water pump 1012 to start the water pump 1012, and the condensed water is discharged to the factory service end through the water pump 1012, so as to recycle the condensed water.

[0096] In some embodiments, the drying device may further include a control module 1030, and the evaporator 20, the compressor 40, the condenser 30, the first fan 71, the second fan 72, the temperature sensor 81, the water level sensor 82, the water pump 1012 and other components may be electrically connected to the control module 1030, so as to facilitate signal processing and issuing control instructions through the control module 1030. Exemplarily, the control module 1030 may be a PLC control module 1030. It should be noted here that the specific structure and working principle of the control module 1030 may refer to the prior art and will not be elaborated in detail here.

[0097] In some embodiments, the drying device may further include a gas-liquid separator 1020, which may be connected between the compressor 40 and the evaporator 20 to separate the gas and liquid of the refrigerant evaporated by the evaporator 20, thereby effectively preventing insufficiently evaporated liquid refrigerant from entering the compressor 40. It should be noted here that the specific structure and working principle of the gas-liquid separator 1020 may refer to the prior art and will not be elaborated in detail here.

[0098] In addition, a display screen, a touch screen, etc. may also be provided on the housing 10 to display the operating status and facilitate operation.

[0099] To summarize, the drying device in the embodiment of the present application is based on the "reverse Carnot" principle. The phase-changeable refrigerant changes from liquid to gas in the evaporator 20, absorbs the heat in the surrounding air into the refrigerant, and compresses the gaseous refrigerant through the compressor 40 to form a high-temperature and high-pressure gaseous refrigerant. The heat of the high-temperature and high-pressure gaseous refrigerant is transferred to the air through the condenser 30 to form a high-temperature gas. Finally, the high-temperature gas contacts the workpiece to be dried to achieve a drying effect. Compared with the heating method of high-power heating tubes, the drying device in the embodiment of the present application can greatly reduce energy consumption, there is no risk of high-temperature burning, and through the phase change of the refrigerant, it can continuously and stably provide appropriate heat, and is less affected by the external environment.
