[0043] Embodiment 1

[0044] like Figure 1As shown, the first aspect of the present application provides a forced cooling system, comprising a forced cooling chamber 11, a first air path 2, a second air path 3, a third air path 4, a first temperature measuring unit and a control unit arranged in a workshop 1. The forced cooling chamber 11 has an air inlet 111 and an air outlet 112; the output ends of the first air path 2, the second air path 3 and the third air path 4 are all connected to the air inlet 111, the input end of the first air path 2 is connected to the workshop environment 12, the input end of the second air path 3 is connected to the workshop environment 13, and the input end of the third air path 4 is connected to the air conditioning unit 14; the first temperature measuring unit is arranged in the workshop environment 12, and is used to detect the first temperature parameter of the workshop environment 12; the control unit is connected to the first temperature measuring unit, the first air path 2, the second air path 3 and the third air path 4, and the control unit controls the output air volume of the first air path 2, the second air path 3 and the third air path 4 according to the first temperature parameter, so that the forced cooling chamber 11 has different cooling capacity.

[0045] Specifically, the forced cooling chamber 11 forms a wind circulation channel inside through the air inlet 111 and the air outlet 112. When the object to be forced cooled is placed in the forced cooling chamber 11, the forced cooling chamber 11 provides coldness to cool the object to be forced cooled. After heat exchange with the object to be forced cooled, there is gas with high heat in the forced cooling chamber 11. This part of the gas is discharged from the forced cooling chamber 11 in time through the air outlet 112 to ensure that the coldness of the forced cooling chamber 11 is maintained. Since the gas with high heat has low density, it is usually located in the upper space of the room of the forced cooling chamber 11. The air outlet 112 is generally arranged at the top of the forced cooling chamber 11, which is specifically based on the actual production layout and is not limited here.

[0046] The air inlet 111 is connected to the output ends of three air paths, which are the first air path 2 connected to the environment outside the workshop 12, the second air path 3 connected to the environment inside the workshop 13, and the third air path 4 connected to the air conditioning unit 14. The air inlet 111 can be set to one or more, and can be set on the top or the side wall of the forced cooling chamber 11. It should be noted that it is spaced from the position of the exhaust port 112 and spaced at a certain distance to ensure that the wind in the forced cooling chamber 11 is fully circulated to provide cooling. The purpose of setting three air paths in this application is to make full use of the ambient temperature and provide multiple options for the wind supply method of the forced cooling chamber 11.

[0047] The first temperature measuring unit is disposed in the workshop outside environment 12, and is used to detect a first temperature parameter of the workshop outside environment 12. The first temperature measuring unit can be a temperature sensor, a thermocouple, an infrared thermometer, or other temperature measuring devices.

[0048] The control unit is connected to the first temperature measuring part, the first air path 2, the second air path 3 and the third air path 4. The control unit controls the output air volume of the first air path 2, the second air path 3 and the third air path 4 according to the first temperature parameter, so that the forced cooling chamber 11 has different cooling capacity. For example, the control unit is provided with a first preset temperature threshold and a second preset temperature threshold, and the second preset temperature threshold is greater than the first preset temperature threshold. When the first temperature parameter is greater than the second preset temperature threshold, usually in the summer environment, due to the high temperature of the workshop external environment 12 and the workshop internal environment 13, the control unit can close the first air path 2 and the second air path 3, and only open the third air path 4 connected to the air conditioning unit 14 to output cold air to the forced cooling chamber 11, and the opening degree of the third air path 4 can be adjusted according to the desired cooling capacity, and the output power of the air conditioning unit 14 can also be adjusted.

[0049] When the first temperature parameter is less than the first preset temperature threshold, usually in winter, since the environment outside the workshop 12 is relatively cold, in order to save energy and make full use of the ambient cold, the control unit can close the second air path 3 and the third air path 4, and only open the first air path 2 connected to the environment outside the workshop 12 to output cold air to the forced cooling chamber 11. It is also possible to open the third air path 4 while opening the first air path 2 to adjust the output air volume to the forced cooling chamber 11 on the basis of controlling the opening degree of the third air path 4, so that the forced cooling chamber 11 has different cold capacities.

[0050] When the first temperature parameter is between the first preset threshold and the second preset threshold, usually in spring or autumn, in order to save energy, the second air duct 3 connected to the workshop environment 13 can be used to output cold air to the forced cooling chamber 11, or the second air duct 3 and the third air duct 4 can be opened in coordination, and the cooling level of the forced cooling chamber 11 can be regulated by controlling the opening of the two. Or in order to improve the system response speed, a third preset threshold can be set between the first preset threshold and the second preset threshold. When the first temperature parameter is in a hot range in the spring and autumn environment, the second air duct 3 is opened while the third air duct 4 is opened. When the first temperature parameter is in a cold range in the spring and autumn environment, only the second air duct 3 is opened. The present application is not limited to the control strategy described above. The output air volume and opening and closing conditions of the three air ducts in the present application are adjusted and selected according to actual conditions.

[0051] The first aspect of the present application provides a forced cooling system, comprising a forced cooling chamber 11, a first air path 2, a second air path 3, a third air path 4, a first temperature measuring unit and a control unit arranged in a workshop 1. The forced cooling chamber 11 has an air inlet 111 and an air outlet 112; the output ends of the first air path 2, the second air path 3 and the third air path 4 are all connected to the air inlet 111, the input end of the first air path 2 is connected to the workshop environment 12, the input end of the second air path 3 is connected to the workshop environment 13, and the input end of the third air path 4 is connected to the air conditioning unit 14; the first temperature measuring unit is arranged in the workshop environment 12, and is used to detect the first temperature parameter of the workshop environment 12; the control unit is connected to the first temperature measuring unit, the first air path 2, the second air path 3 and the third air path 4, and the control unit controls the output air volume of the first air path 2, the second air path 3 and the third air path 4 according to the first temperature parameter, so that the forced cooling chamber 11 has different cooling capacity. The present application provides cooling capacity by connecting three different air paths to the forced cooling chamber 11. Under the control of the control unit, the environment outside the workshop 12, the environment inside the workshop 13 and the air conditioning unit 14 are individually or arbitrarily combined to supply air to the forced cooling chamber 11 according to the first temperature parameter outside the workshop 1. Therefore, for different weather environments in spring, summer, autumn and winter, the present application can provide a variety of air path options to provide cooling capacity for the forced cooling chamber 11, and the control unit controls the output air volume of the air path according to the first temperature parameter, thereby achieving reasonable allocation among multiple air paths, fully distinguishing and utilizing the ambient temperature, and achieving the purpose of energy saving. Through the application of the utility model, the problem that the forced cooling chamber 11 in the prior art uses a single air cooling system to cool the vehicle body for a long time, ignores the distinction and utilization of the ambient temperature, and causes a large amount of resource waste is solved.

[0052] like Figure 2 As shown, in some embodiments, it also includes an air supply cavity 15 arranged in the workshop 1 and located above the forced cooling chamber 11, the first end of the air supply cavity 15 is connected to the air inlet 111, and the second end of the air supply cavity 15 facing away from the forced cooling chamber 11 is provided with a first opening 151 and a second opening 152, the first opening 151 is connected to the output end of the first air path 2, and the second opening 152 is connected to the output end of the second air path 3; a first air valve 21 is provided in the first air path 2, and a second air valve 31 is provided in the second air path 3, and the first air valve 21 and the second air valve 31 are connected to the control unit.

[0053] Specifically, the present application further provides an air supply cavity 15 above the forced cooling chamber 11, and the output ends of the first air path 2 and the second air path 3 are connected through a first opening 151 and a second opening 152 provided on the air supply cavity 15. The first air path 2 and the second air path 3 have a common air supply channel when supplying air to the forced cooling chamber 11, saving layout costs and space required for layout.

[0054] At the same time, the output air volume of the first air path 2 and the second air path 3 is controlled by the first air valve 21 and the second air valve 31 correspondingly arranged therein, so as to correspond to the control strategies of different seasons, adjust the opening of the first air valve 21 and the second air valve 31, and adjust the cooling capacity of the strong cooling chamber 11 under different output air volumes. Similar to the control method of the first air path 2 and the second air path 3, the third air path 4 can also be provided with air valves to achieve the adjustment of different openings, or directly control the output power adjustment of the air conditioning unit 14.

[0055] In addition, an exhaust cavity may be provided above the forced cooling chamber 11 of the present application, and the exhaust cavity is connected to the exhaust port 112 of the forced cooling chamber 11 , and at the same time, one end of the exhaust cavity away from the forced cooling chamber 11 is connected to the environment 12 outside the workshop.

[0056] In order to improve the efficiency of air supply and exhaust, and increase the cold supply and heat discharge per unit time, the present application can also respectively set wind wheels at the positions where the air inlet 111 and the air outlet 112 connect the air supply cavity 15 and the exhaust cavity, and the wind wheels are connected to the fan, which drives the cold air to enter and the hot air to be discharged.

[0057] like Figure 3 As shown, in some embodiments, a first surface cooler 153 is arranged on the air supply path in the air supply cavity 15; a second temperature measuring part is also arranged in the air supply cavity 15, and the second temperature measuring part is used to detect the second temperature parameter in the air supply cavity 15; the first surface cooler 153 and the second temperature measuring part are connected to the control unit, and the control unit controls the output cooling capacity of the first surface cooler 153 according to the second temperature parameter.

[0058] Specifically, in order to further cool down the first air path 2 and the second air path 3 before they are input into the strong cooling chamber 11, the present application sets a first surface cooler 153 on the air supply path of the air supply cavity 15, and the first surface cooler 153 can be connected to the refrigeration unit through a chilled water circulation pipeline. The second temperature measuring part is used to detect the second temperature parameter in the air supply cavity 15, and a preset threshold is correspondingly set to adjust the cooling effect of the first surface cooler 153 according to the relative relationship between the second temperature parameter and the preset threshold. The adjustment method can be achieved by adjusting the chilled water valve on the chilled water circulation pipeline, or by adjusting the output power of the refrigeration unit.

[0059] like Figure 4 As shown, in some embodiments, a first filter 154 and a second filter 155 are further disposed in the air supply cavity 15 . The first filter 154 and the second filter 155 are both located on the air supply path and are respectively disposed on both sides of the first surface cooler 153 .

[0060] Specifically, in order to clean the air input to the forced cooling chamber 11 and improve the air supply efficiency of the system, the air supply cavity 15 of the present application is further provided with a first filter 154 and a second filter 155, both of which are located on the air supply path and are respectively arranged on both sides of the first surface cooler 153. The air output from the first air path 2 or the second air path 3 to the air supply cavity 15 passes through the first filter 154 before reaching the first surface cooler 153. The first filter 154 filters the incoming air from the workshop environment 12 or the workshop environment 13, reduces impurities in the air environment, ensures the cleanliness of the incoming air, and prevents the first surface cooler 153 from being blocked. After being cooled by the first surface cooler 153, the air is further filtered by the second filter 155 before entering the forced cooling chamber 11 to enhance the cleanliness of the outlet air.

[0061] It should be noted that the first filter 154 and the second filter 155 can use devices of the same filtration grade or devices of different filtration grades. In one embodiment, the first filter 154 uses the G4 grade and the second filter 155 uses the F6 grade, wherein G4 and F6 are divided according to European standards, G4 represents a primary or coarse filter, usually as the first layer of multi-stage filtration, and F6 represents a medium-efficiency filter, which has a better filtering effect than G4.

[0062] like Figure 5 As shown, in some embodiments, a plurality of partitions 113 are provided in the forced cooling chamber 11, and the plurality of partitions 113 have through holes 1131 and divide the forced cooling chamber 11 into a first space 114, a second space 115 and a third space 116 which are connected in sequence, the air inlet 111 is provided on the side wall of the first space 114 away from the second space 115, the air outlet 112 is provided on the side wall of the third space 116 away from the second space 115, and the second space 115 is used to accommodate an object to be forced cooled; a condenser 1141 is provided in the first space 114, and the condenser 1141 is provided corresponding to the air inlet 111, so that the wind entering the air inlet 111 passes through the condenser 1141 and enters the second space 115 along the through holes 1131.

[0063] Specifically, in order to concentrate the cold air in the strong cooling chamber 11 to perform strong cooling operations on the objects to be cooled, the present application defines a strong cooling operation space for the objects to be cooled through a partition 113, namely, a second space 115. In actual production, the strong cooling operation requirements are met by regulating the cold amount of the second space 115, which reduces the difficulty and saves energy compared to regulating the cold amount of the entire space of the strong cooling chamber 11.

[0064] The present application divides the forced cooling chamber 11 into a first space 114, a second space 115 and a third space 116 which are connected in sequence, wherein the second space 115 is used to accommodate an object to be forced cooled, and the first space 114, the second space 115 and the third space 116 are separated by a partition 113 having a through hole 1131, and an air inlet 111 is arranged on a side wall of the first space 114 away from the second space 115, and an air outlet 112 is arranged on a side wall of the third space 116 away from the second space 115, so that the wind entering the forced cooling chamber 11 forms a circulation channel from the first space 114 to the second space 115 and then to the third space 116, thereby meeting the requirements of cooling and heat dissipation.

[0065] In order to make the second space 115 have a higher cooling capacity to cool the object to be cooled, a condenser 1141 is arranged in the first space 114 of the present application. The condenser 1141 is arranged corresponding to the air inlet 111, so that the wind entering the air inlet 111 passes through the condenser 1141 and enters the second space 115 along the through hole 1131. A refrigerant such as Freon, propane or isobutane flows in the condenser 1141, and the wind entering the second space 115 is made to have a lower temperature by exchanging heat with the wind in the first space 114, so as to provide a higher cooling capacity.

[0066] like Figure 6 As shown, in some embodiments, the first space 114 and the second space 115 are arranged in a horizontal direction, there are two first spaces 114 and they are respectively located on both sides of the second space 115, there are two air inlets 111 and they are relatively arranged on the side walls of the first space 114 away from the second space 115, there are two condensers 1141 and they are respectively arranged in the two first spaces 114, and the third space 116 is located at the top of the second space 115.

[0067] Specifically, in order to improve the circulation efficiency of the cold air in the forced cooling chamber 11 and to provide a higher cooling capacity per unit time in the forced cooling chamber 11, the present application sets two first spaces 114 respectively located on both sides of the second space 115, the air inlets 111 are two and are relatively arranged on the side walls of the first space 114 away from the second space 115, the condensers 1141 are two and are respectively arranged in the two first spaces 114, and the third space 116 is located at the top of the second space 115, so as to form two cold air circulation channels in the forced cooling chamber 11. The two cold air circulation channels provide cold air to the second space 115 at the same time, and the cold air is also affected by the heat exchange of the condensers 1141 and has a lower temperature.

[0068] In some embodiments, a third temperature measuring unit is provided in the second space 115, and the third temperature measuring unit is used to detect a third temperature parameter of the second space 115; the condenser 1141 and the third temperature measuring unit are connected to the control unit, and the control unit controls the output cooling capacity of the condenser 1141 according to the third temperature parameter.

[0069] Specifically, since the second space 115 is used as a space for strong cooling of the object to be cooled, the internal temperature of the second space 115 affects the effect and efficiency of the strong cooling operation. In the present application, a third temperature measuring unit is provided in the second space 115, and the third temperature measuring unit is used to detect the third temperature parameter of the second space 115. The control unit controls the output cooling capacity of the condenser 1141 according to the third temperature parameter to achieve a better heat exchange effect and regulate the temperature in the second space 115. At the same time, when the temperature of the second space 115 meets the requirements, the setting of the third temperature measuring unit and the control unit enables the condenser 1141 to not need to operate under certain circumstances, saving energy.

[0070] In some embodiments, a second cooler is further provided in the first space 114, and the second cooler and the condenser 1141 are placed side by side and spaced apart in the first space 114; the second cooler is connected to the control unit, and the control unit controls the output cooling capacity of the second cooler according to the third temperature parameter.

[0071] Specifically, in order to improve the circulation efficiency of the cold air in the strong cooling chamber 11 and to provide a higher cooling capacity in the strong cooling chamber 11 per unit time, a second surface cooler is also provided in the first space 114. The second surface cooler is placed side by side and at intervals with the condenser 1141 in the first space 114, so as to cooperate with the condenser 1141 to cool the cold air in the first space 114 and improve the cooling efficiency.

[0072] At the same time, since the second space 115 is used as a space for strong cooling of the object to be cooled, the internal temperature of the second space 115 affects the effect and efficiency of the strong cooling operation. The second cooler is connected to the control unit, and the control unit controls the output cooling capacity of the second cooler according to the third temperature parameter to achieve a better heat exchange effect and adjust the temperature in the second space 115. At the same time, when the temperature of the second space 115 meets the requirements, the setting of the third temperature measuring part and the control unit enables the second cooler to be free of operation under certain circumstances, saving energy. The first cooler 153 can be connected to the refrigeration unit through a chilled water circulation pipeline, and the cooling effect of the second cooler can be adjusted according to the third temperature parameter. The adjustment method can be achieved by adjusting the chilled water valve on the chilled water circulation pipeline, or by adjusting the output power of the refrigeration unit.

[0073] like Figure 7 As shown, in some embodiments, there are multiple through holes 1131 on the partition 113 between the first space 114 and the second space 115, and the diameters of the through holes 1131 increase downward along the vertical direction.

[0074] Specifically, there are multiple through holes 1131 on the partition 113 between the first space 114 and the second space 115, and the multiple through holes 1131 are arranged in an array on the partition 113. The form of the array is not limited. The multiple through holes 1131 serve as cold air channels connecting the first space 114 and the second space 115. The number of arrangements takes into account the cooling demand of the second space 115 and ease of production and manufacturing.

[0075] In order to increase the amount of cold air between the first space 114 and the second space 115, taking into account that the density of cold air is relatively large and affected by gravity, the unit mass of cold air at the lower position in the vertical direction is relatively large. Therefore, the present application arranges the diameter of the through hole 1131 on the partition 113 to increase downward in the vertical direction, so that the through hole 1131 at the lower position has a larger diameter to pass more cold air, thereby increasing the amount of cold air output for the second space 115 per unit time.

[0078] Specifically, please refer to the first embodiment for the specific structure of the forced cooling system, which will not be described in detail here.

[0079] In the coating production line, taking new energy vehicles as an example, it generally needs to go through multiple strong cold chambers 11 such as electrophoresis drying strong cold chamber 11, glue drying strong cold chamber 11, color paint flashing strong cold chamber 11 and topcoat drying strong cold chamber 11 during the coating process. Under normal circumstances, after the white body is pre-treated with electrophoresis, the electrophoresis body is dried. After the drying furnace bakes the electrophoresis body, the electrophoresis body needs to be cooled before the gluing process. After the gluing is completed, the glue is dried and cooled, and then the painting process is carried out. After the color paint is sprayed, it must go through a flash drying furnace and cooling, and then enter the varnish spraying process, and finally the body spraying is completed after the topcoat is dried and the strong cold chamber 11. The present application is for the above-mentioned electrophoresis drying strong cold chamber 11, glue drying strong cold chamber 11, color paint flashing strong cold chamber 11 and topcoat drying strong cold chamber 11 and other multiple strong cold chambers 11 adopt the strong cooling system provided by the present application, fully distinguish and utilize the ambient temperature, cool the body while saving energy, and ensure the operation of the coating production line.

The forced cooling system includes a forced cooling chamber 11, a first air path 2, a second air path 3, a third air path 4, a first temperature measuring unit and a control unit arranged in a workshop 1. The forced cooling chamber 11 has an air inlet 111 and an air outlet 112; the output ends of the first air path 2, the second air path 3 and the third air path 4 are all connected to the air inlet 111, the input end of the first air path 2 is connected to the workshop environment 12, the input end of the second air path 3 is connected to the workshop environment 13, and the input end of the third air path 4 is connected to the air conditioning unit 14; the first temperature measuring unit is arranged in the workshop environment 12, for detecting the first temperature parameter of the workshop environment 12; the control unit is connected to the first temperature measuring unit, the first air path 2, the second air path 3 and the third air path 4, and the control unit controls the output air volume of the first air path 2, the second air path 3 and the third air path 4 according to the first temperature parameter, so that the forced cooling chamber 11 has different cooling capacity. The present application provides cooling capacity by connecting three different air paths to the forced cooling chamber 11. Under the control of the control unit, the environment outside the workshop 12, the environment inside the workshop 13 and the air conditioning unit 14 are individually or arbitrarily combined to supply air to the forced cooling chamber 11 according to the first temperature parameter outside the workshop 1. Therefore, for different weather environments in spring, summer, autumn and winter, the present application can provide a variety of air path options to provide cooling capacity for the forced cooling chamber 11, and the control unit controls the output air volume of the air path according to the first temperature parameter, thereby achieving reasonable allocation among multiple air paths, fully distinguishing and utilizing the ambient temperature, and achieving the purpose of energy saving. Through the application of the utility model, the problem that the forced cooling chamber 11 in the prior art uses a single air cooling system to cool the vehicle body for a long time, ignores the distinction and utilization of the ambient temperature, and causes a large amount of resource waste is solved.
