Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, and in particular to a battery shell with a temperature control function. Background Art

[0002] A battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, MS Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream.

[0003] However, lithium batteries may generate heat and be damaged due to high heat during operation. The heat energy generated by traditional lithium batteries during operation can only be dissipated to the external environment through their outer casing, and the heat dissipation effect is relatively poor. In addition, if high heat is generated after an internal failure, dangerous situations such as lithium battery combustion may occur. Users are quite troubled by this, so a battery casing with a temperature control function is proposed. Utility Model Content

[0007] Preferably, a symmetrical exhaust fan is provided on the bottom wall of the lithium battery shell, a heating box is glued at the center of the bottom wall of the lithium battery shell, a heater is provided in the heating box, a partition is welded at the lower part of the lithium battery shell, a plurality of air holes are opened on the partition, and bonding plates are welded on both sides of the partition.

[0010] Preferably, the control panel has a display screen function for displaying temperature changes, and the control panel is electrically connected to the temperature sensor, the circulating water pump, the exhaust fan and the heater respectively.

[0011] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0012] The battery housing with temperature control function provided by the utility model is provided with a temperature sensor, a control panel, a liquid storage cavity, a circulating water pump, a liquid inlet pipe, a cooling coil and a liquid outlet pipe. When the temperature sensor senses that the internal temperature of the lithium battery housing is too high and exceeds the set value, the control panel is used to control the circulating water pump to start. The circulating water pump starts to make the coolant flow in the cooling coil, thereby recycling the coolant, increasing the heat exchange efficiency, improving the heat dissipation effect, and avoiding the lithium battery from being damaged or exploded due to high heat;

[0013] The utility model is provided with an exhaust fan, a partition and a vent hole. The exhaust fan is started by controlling the control panel, and the exhaust fan blows air so that the hot air inside the lithium battery housing is blown to the bonding plates on both sides through the vent hole, further improving the heat dissipation effect.

[0014] The utility model greatly improves the heat dissipation effect of the lithium battery shell by arranging a plurality of heat dissipation fins on the outer side of the lithium battery shell;

[0015] The utility model is provided with a temperature sensor, a control panel, a heating box and a heater. When the temperature sensor senses that the temperature inside the lithium battery shell is too low and exceeds a set value, the control panel controls the heater inside the heating box to start, and at the same time the control panel controls the exhaust fan to blow air. After being heated by the heater, the wind blows into the lithium battery shell through the air vents, thereby adjusting the temperature inside the lithium battery shell.
