Internal liquid cooling type conductive contact member and connector

Abstract

The present invention relates to an internal liquid cooling type conductive contact member and a connector. The connector of the present invention comprises the internal liquid cooling type conductive contact member, the internal liquid cooling type conductive contact member comprises a contact member body in which a flow passage is arranged, and an insulating layer is arranged on the inner wall of the flow passage. A cooling liquid can flow in the flow passage from a liquid inlet and flows through the flow passage, absorbs the heat transmitted by the contact member to the insulating layer during the flow process, and then flows out from a liquid outlet and is cooled externally, thereby realizing the circular heat transfer, conducting and radiating the heat of the contact member. The liquid flow speed of the cooling liquid can be adjusted appropriately according to the heat of the contact member, thereby cooling the contact member well under the premise of not reducing a current of the contact member.

Description

technical field [0001] The invention relates to an internal liquid-cooled conductive contact piece and a connector. Background technique [0002] The conductive contact will generate a certain amount of heat due to the existence of resistance when the current passes, resulting in the temperature rise of the contact. In order to solve the problem of temperature rise of the contact, it is usually achieved by controlling the magnitude of the current, that is, when the contact When the heat is too large, the temperature rise of the contact can be reduced by reducing the current. When the temperature is too high, it is even necessary to stop the current input, and then conduct the current input after the contact is cooled, which makes the contact impossible. Long-term continuous use, or the passing current cannot pass through a large current for a long time, which will affect the normal use of the contacts and affect the work efficiency.
