Description

Technical Field

[0001] The utility model relates to the technical field of battery processing equipment, in particular to an automatic switching energy-saving device for high and low temperature boxes of lithium batteries. Background Art

[0002] With the rapid development of the lithium battery industry, the requirements for the temperature of lithium battery high and low temperature boxes vary depending on the production environment of lithium batteries in different regions. Not only does it need to control the temperature not to be too high, it must be heated in low temperature environments, and it must be kept dry during the production process. However, the existing lithium battery high and low temperature boxes have relatively single and fixed functions and cannot flexibly respond to production needs in different regional environments, so they need to be improved. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the utility model proposes an automatic switching energy-saving device for high and low temperature boxes of lithium batteries, which can effectively deal with the influence of temperature, moisture, dust, etc. on batteries in production environments in different regions, and ensure the quality and performance of the batteries.

[0004] To achieve the above technical solution, the utility model provides an automatic switching energy-saving device for a lithium battery high and low temperature box, comprising: a high and low temperature box body, an inner warehouse is arranged in the high and low temperature box body, a temperature control system is installed in the inner warehouse, the temperature control system comprises a ventilation plate, a heating component, a heat exchanger and a fan, the ventilation plate is installed on the right side of the inner warehouse, the upper surface of the ventilation plate is evenly provided with heat exchange outlet holes, the lower surface of the ventilation plate is evenly provided with heat exchange inlet holes, the heating component is installed on the back of the ventilation plate and is located below the heat exchange outlet holes, the heat exchanger is installed on the back of the ventilation plate and is located below the heating component, the fan is installed on the back of the ventilation plate and is located below the heat exchanger, the air outlet of the fan is arranged opposite to the heat exchanger, the air inlet of the fan is arranged opposite to the heat exchange inlet holes opened on the lower end surface of the ventilation plate, a liquid receiving pan is installed on the back of the ventilation plate between the heat exchanger and the fan, and a plurality of temperature sensors are installed on the surface of the inner warehouse.

[0005] In the above technical scheme, in actual operation, hot fluid can be supplied to the heat exchanger to increase the temperature of the inner warehouse according to the existing conditions in the production area, or cold fluid can be supplied to the heat exchanger to cool the temperature of the inner warehouse. In areas without fluid conditions, the heating component can be used to heat the inner warehouse, and it can be switched according to the existing conditions in actual use. When it is necessary to increase the temperature of the inner warehouse, the hot fluid is supplied to the heat exchanger (the heating component does not work at this time), and the fan draws out the air in the inner warehouse through the heat exchange inlet hole opened on the lower surface of the ventilation plate. After passing through the heat exchanger, the air absorbs the heat of the hot fluid, and the temperature of the air is increased. Then, the air enters the inner warehouse through the heat exchange outlet hole opened on the upper surface of the ventilation plate, thereby increasing the temperature of the inner warehouse. When it is necessary to increase the temperature of the inner warehouse, if there is no condition for hot fluid, the heating component can be directly turned on, and the air can be heated by electric heat, which can also achieve the effect of increasing the temperature of the inner warehouse. When the temperature of the inner chamber needs to be lowered, the cold fluid is supplied to the heat exchanger, and the fan draws out the air in the inner chamber through the heat exchange inlet hole opened on the lower surface of the ventilation plate. After passing through the heat exchanger, the air exchanges heat with the cold fluid, and the temperature of the air is lowered. Then, the air enters the inner chamber through the heat exchange outlet hole opened on the upper surface of the ventilation plate, thereby reducing the temperature of the inner chamber. If the air humidity in the inner chamber is high and the air in the inner chamber needs to be dried, the heating component is turned on, and a low-temperature cold fluid is supplied to the heat exchanger. The heating component will heat the air, and the fan will draw out the hot air in the inner chamber. After passing through the heat exchanger, the hot air will quickly cool down when it encounters a low-temperature heat exchanger. When the water vapor in the air is cooled, it will condense and gather on the heat exchanger, thereby forming water droplets. The water droplets continuously drip onto the liquid receiving tray, and the water flows from the outlet of the liquid receiving tray to the outside of the high and low temperature box body, thereby achieving the purpose of drying the air. And the speed of extracting air can be controlled by controlling the speed of the fan, so as to achieve the characteristic of temperature regulation. When the speed remains unchanged, the heat sucked away by the air is constant, so as to achieve the purpose of constant temperature.

[0006] Preferably, the heating assembly includes a heating pipe, a left heating pipe bracket, a right heating pipe bracket and a fixed joint, wherein the left heating pipe bracket and the right heating pipe bracket are respectively fixed on the back of the ventilation plate, and the heating pipe is fixed to the left heating pipe bracket and the right heating pipe bracket through the fixed joint. In actual operation, the heating pipe can be turned on to heat the air according to specific circumstances.

[0007] Preferably, the heat exchanger comprises a heat exchanger frame, in which a plurality of groups of heat exchange tubes are installed, the heat exchange tubes are connected through elbows, and the ends of the heat exchange tubes are provided with liquid inlet pipes and liquid outlet pipes. In actual operation, hot fluid or cold fluid can be injected into the heat exchange tubes through the liquid inlet pipes, and the hot fluid or cold fluid can be circulated through the liquid outlet pipes.

[0008] Preferably, the ventilation plate is installed on the right side of the inner compartment and is closed by a sealing cover to ensure that air can circulate in the enclosed space.

[0009] Preferably, a control panel is installed on the outer side of the high and low temperature box body, and the control panel is electrically connected to the temperature control system and the temperature sensor. During actual operation, the operating parameters can be set through the control panel.

[0010] The utility model provides a lithium battery high and low temperature box automatic switching energy-saving device with beneficial effects in that: the lithium battery high and low temperature box automatic switching energy-saving device has a simple structure, reasonable design, and convenient operation. It can effectively deal with the impact of temperature, moisture, dust, etc. on batteries in production environments in different regions, and ensure the quality and performance of the batteries. When there are cold and hot fluids in different regional environments, the speed of the fan can be controlled to blow upwards in the heat exchanger, and the air in the closed inner warehouse can be circulated through the ventilation plate, and the temperature of the inner warehouse can be quickly raised or dropped to the same temperature as the fluid to achieve energy saving and emission reduction. When there is no fluid, the heating component is operated by the heating tube to generate heat, and the fan blows upwards to circulate the air in the closed inner warehouse through the ventilation plate. After the temperature in the warehouse rises rapidly to the specified temperature, the heating component stops, the heat exchanger runs, and the fan continues to run. When the hot air meets the cold, condensed water is formed, and small water droplets are generated and attached to the liquid supply pipe. Flow into the liquid receiving tray and discharge it out of the high and low temperature box body to achieve a drying effect. When the temperature is heated or lowered to the specified temperature as required, the temperature control system is started to automatically adjust the temperature through temperature measurement by temperature sensors and control of fan speed, so as to achieve constant temperature.

In actual operation, the heating pipe 421 can be turned on to heat the air according to specific circumstances.

[0018] The heat exchanger 43 is installed on the back of the ventilation plate 48 and below the heating assembly 42. The heat exchanger 43 includes a heat exchanger frame 431. A plurality of heat exchange tubes 432 are installed in the heat exchanger frame 431. The heat exchange tubes 432 are connected through elbows 435.

In actual operation, hot fluid or cold fluid can be injected into the heat exchange tubes 432 through the liquid inlet pipes 433, and the hot fluid or cold fluid can be circulated through the liquid outlet pipes 434.

[0019] The fan 45 is installed on the back of the ventilation plate 48 and is located below the heat exchanger 43. The air outlet of the fan 45 is arranged opposite to the heat exchanger 43, and the air inlet of the fan 45 is arranged opposite to the heat exchange air inlet hole 46 opened on the lower end surface of the ventilation plate 48. In actual operation, the fan 45 sucks the air in the inner warehouse 3 through the heat exchange air inlet hole 46 opened on the lower end surface of the ventilation plate 48, and then directs the sucked air upward through the air outlet of the fan 45 to exchange heat with the heat exchanger 43 and the heating component 42 respectively. The air after heat exchange finally enters the inner warehouse 3 through the heat exchange air outlet hole 41 opened on the upper end surface of the ventilation plate 48, thereby realizing heat exchange and circulation of the air in the inner warehouse 3.

[0020] A liquid receiving pan 44 is installed on the back of the ventilation plate 48 between the heat exchanger 43 and the fan 45. When water droplets appear on the surface of the heat exchanger 43, the water droplets will continuously drip onto the liquid receiving pan 44, and the water will flow from the outlet of the liquid receiving pan 44 to the outside of the high and low temperature box body 1.

In areas without fluid conditions, the heating component 42 can be used to heat the inner warehouse 3, and it can be switched according to the existing conditions in actual use. When it is necessary to increase the temperature of the inner warehouse 3, the hot fluid is supplied to the heat exchanger 43 (the heating component 42 does not work at this time), and the fan 45 extracts the air in the inner warehouse 3 through the heat exchange air inlet 46 opened on the lower end surface of the ventilation plate 48. After passing through the heat exchanger 43, the air absorbs the heat of the hot fluid, and the temperature of the air is increased. Then, the air enters the inner warehouse 3 through the heat exchange air outlet 41 opened on the upper end surface of the ventilation plate 48, thereby achieving the increase in the temperature of the inner warehouse 3. When it is necessary to increase the temperature of the inner warehouse 3, if there is no hot fluid condition, the heating component 42 can be directly turned on to heat the air by electric heating, which can also achieve the effect of increasing the temperature of the inner warehouse 3. When it is necessary to lower the temperature of the inner warehouse 3, the cold fluid is supplied to the heat exchanger 43, and the fan 45 draws the air in the inner warehouse 3 through the heat exchange air inlet hole 46 opened on the lower end surface of the ventilation plate 48. After passing through the heat exchanger 43, the air exchanges heat with the cold fluid, and the temperature of the air is lowered. Then, the air enters the inner warehouse 3 through the heat exchange air outlet hole 41 opened on the upper end surface of the ventilation plate 48, thereby achieving the reduction of the temperature of the inner warehouse 3. If the air humidity in the inner chamber 3 is high and the air in the inner chamber 3 needs to be dried, the heating component 42 is turned on and a low-temperature cold fluid is supplied to the heat exchanger 43. The heating component 42 will heat the air, and the fan 45 will extract the hot air from the inner chamber 3. After passing through the heat exchanger 43, the hot air will quickly cool down when it encounters the low-temperature heat exchanger 43. When the water vapor in the air is cooled, it will condense and gather on the heat exchanger 43, thereby forming water droplets. The water droplets continuously drip on the liquid receiving tray 44, and the water flows from the outlet of the liquid receiving tray 44 to the outside of the high and low temperature box body 1, thereby achieving the purpose of drying the air. And the speed of extracting air can be controlled by controlling the speed of the fan 45, so as to achieve the characteristic of regulating temperature. When the speed remains unchanged, the heat absorbed by the air is constant, thereby achieving the purpose of constant temperature.

[0023] The automatic switching energy-saving device for high and low temperature boxes of lithium batteries has a simple structure, reasonable design, and convenient operation. It can effectively deal with the impact of temperature, moisture, dust, etc. on batteries in production environments in different regions, and ensure the quality and performance of batteries. When there are cold and hot fluids in different regional environments, the speed of the fan 45 can be controlled to blow upwards in the heat exchanger 43, and the air in the closed inner warehouse 3 is circulated through the ventilation plate 48. The temperature of the inner warehouse 3 rises rapidly or drops to the same temperature as the fluid to achieve energy saving and emission reduction. When there is no fluid, the heating component 42 is operated by the heating tube 421 to generate heat, and the fan 45 blows upwards, and the air in the closed inner warehouse 3 is circulated through the ventilation plate 48. After the temperature of the inner warehouse 3 rises rapidly to the specified temperature, the heating component 42 stops, the heat exchanger 43 runs, and the fan 45 continues to run. When the hot air meets the cold, condensed water is formed, and small water droplets are generated and attached to the heat exchanger 43 to flow into the liquid receiving tray 44 to discharge it outside the high and low temperature box body 1, so as to achieve the effect of drying.
