Problems solved by technology

[0002] As we all know, electric vehicles powered by on-board energy storage devices such as supercapacitors and batteries have not only the safety and reliability of useful electricity, but also the temperature of the power supply. Repeated charging and discharging of energy storage devices and long-term high-intensity The use of the energy storage device makes the temperature inside the energy storage device rise sharply, especially in the case of high temperature in summer. For example, in the south, the surface temperature can reach 50-60 degrees, and the internal temperature of the energy storage device is as high as 70-80 degrees. This is far beyond the normal operating temperature range of the energy storage device. High temperature will not only damage the internal structure of the energy storage device, but also make the consistency of the unit power supply worse, abnormal charging and discharging, etc., and in severe cases will lead to Phenomena such as short circuit and burning of energy storage device

Embodiment 1

[0018] 1, 2, and 3, the cooling and heat dissipation system used for energy storage devices such as supercapacitors and batteries in this embodiment include a battery or a supercapacitor unit 2, and the surrounding periphery of the battery or supercapacitor unit 2 is covered with a pattern of the same type. For the same heat sink 1, the interior of the heat sink 1 is made into a relatively smooth plane, and the joint surface of the heat sink 1 and the battery or supercapacitor monomer 2 is closely combined, and the height of the heat sink 1 is smaller than the height of the battery or supercapacitor monomer casing Dimensions, the outer sides of both ends of the heat sink 1 are made into a transverse concave-convex shape. When multiple batteries or supercapacitors are combined together, the protruding parts of the heat sink 1 are just facing each other in sequence, and the air duct 3 is formed in the middle; When the capacitor monomers are combined into a capacitor bank, louvers...

Abstract

The invention comprises: a battery or a super capacitor. It features the radiating fins covering said battery and super capacitor; both ends of battery or super capacitor are uncovered; multi batteries or super capacitors are combined to form a battery pack compartment or super capacitor compartment. The invention can used to cool the batteries or capacitors.

Description

1. Technical field [0001] The invention relates to a cooling and heat dissipation system for energy storage devices such as supercapacitors and batteries, and belongs to the technical field of cooling and heat dissipation device structures. 2. Background technology [0002] As we all know, electric vehicles powered by on-board energy storage devices such as supercapacitors and batteries have not only the safety and reliability of useful electricity, but also the temperature of the power supply. Repeated charging and discharging of energy storage devices and long-term high-intensity The use of the energy storage device makes the temperature inside the energy storage device rise sharply, especially in the case of high temperature in summer. For example, in the south, the surface temperature can reach 50-60 degrees, and the internal temperature of the energy storage device is as high as 70-80 degrees.
