Title:
HEAT DISSIPATION STRUCTURE, HIGH VOLTAGE BOX, BATTERY, AND ELECTRICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/185244
Kind Code:
A1
Abstract:
The present application relates to the technical field of batteries, and provides a heat dissipation structure, a high voltage box, a battery, and an electrical device. The heat dissipation structure comprises: a housing for forming an accommodating cavity; a heating source provided in the accommodating cavity, the heating source having a heat dissipation surface, the heating source being provided with a first connecting portion; and a heat conduction block inserted into the housing and having at least one surface exposed to an outer side of the housing, the heat conduction block having a first heat conduction surface, the heat conduction block being provided with a second connecting portion, the first connecting portion and the second connecting portion being directly connected or connected by means of a connecting member, so that the first heat conduction surface and the heat dissipation surface are kept attached. The first connecting portion of the heat conduction block and the second connecting portion of the heating source are directly connected or connected by means of the connecting member, so that the first heat conduction surface and the heat dissipation surface are kept attached, so that heat of the heating source can be effectively conducted to the heat conduction block, and the heat conduction block can transfer the heat to the outside of the accommodating cavity, thus ensuring that the heating source and a nearby region thereof are kept at a low temperature level, and further improving the heat dissipation capability and heat dissipation efficiency of the heating source and the nearby region thereof.
