Abstract

A heat sink (10, 100) for dissipating heat from an electrical device comprises a base (20) having a generally flat top surface (21); a plurality of fins (40, 400) arranged on the top surface (21) of the base (20) such that a running direction of the fins (40, 400) is oblique to an in-flow (A) of heat flow; and a plurality of channels (60) defined between each two adjacent fins (40, 400).

Description

technical field [0001] The present invention relates to a heat sink for removing heat from electrical equipment such as switchgears, circuit breakers and transformers. Background technique [0002] Electrical equipment such as switchgear, circuit breakers and transformers generate a lot of heat during operation. If the heat cannot be effectively dissipated, the efficiency of the electrical equipment will be very low, and the equipment may be burned out. Therefore, radiators have become an indispensable part of modern electrical equipment. Moreover, how to provide an effective heat sink has also become a hot topic in the field of electrical industry. [0003] Various heat sinks for dissipating heat generated by electrical equipment have been proposed, examples of which can be found in US Patent Application Publications US 2004141290 and US 2008144279. The radiator proposed in the US patent application US 2004141290 includes a base and a plurality of fins parallel to each o...
