An internal liquid-cooled conductive contact and connector

Abstract

The invention relates to an internal liquid-cooled conductive contact piece and a connector. The connector of the present invention includes an internal liquid-cooled conductive contact. The internal liquid-cooled conductive contact includes a contact body. A liquid flow channel is arranged inside the contact body. An insulating layer is provided on the inner wall of the liquid flow channel. Cooling liquid can be passed in, and the cooling liquid circulates inside it from the liquid flow channel of the liquid inlet port. During the circulation process, the heat absorbed by the contact part is transferred to the insulating layer, and then flows out from the liquid outlet port and is cooled externally to realize circulation. Heat exchange is to complete the heat conduction and heat dissipation of the contacts, and the liquid flow velocity of the cooling liquid can be adjusted appropriately according to the calorific value of the contacts, so as to achieve good cooling of the contacts without reducing the current passing through the contacts.

Description

Technical field [0001] The invention relates to an internal liquid-cooled conductive contact piece and a connector. Background technique [0002] Conductive contacts will generate a certain amount of heat due to the existence of resistance when current passes, which will cause the temperature rise of the contact. In order to solve the temperature rise of the contact, it is usually achieved by controlling the magnitude of the current, that is, when the contact is sent 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 flow. After the contact is cooled, the current can be passed, which makes the contact impossible Long-term continuous use, or the current passing through it cannot pass a large current for a long time, which affects the normal use of the contact and affects the work efficiency. Summary of the invention [0003] The object of the present inve...

[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. Continuous use for a long time, or the current passing through cannot pass a large current for a long time, which will affect the normal use of the contacts and affect the work efficiency
