Cooling fin and radiator with same

Abstract

The invention discloses a cooling fin and a radiator with the same.The cooling fin is internally provided with an oil storage cavity, at least one oil outlet channel and at least one oil return channel; the oil storage cavity is located at the bottom of the cooling fin, and an installing portion used for installing a heating part is arranged in the oil storage cavity; the lower ends of the oil outlet channels form inlet ends and communicated with the upper end of the oil storage cavity; the oil return channels and the oil outlet channels are alternately arranged, the upper ends of the oil return channels are communicated with the upper ends of the oil outlet channels, and the lower ends of the oil return channels downwards extend to the bottom of the oil storage cavity to form outlet ends and are communicated with the oil storage cavity.According to the cooling fin, the inlet ends of the oil outlet channels are arranged to be located over the outlet ends of the oil return channels, high-temperature oil only enters the oil outlet channels, low-temperature oil flows back to the bottom of the oil storage cavity through the oil return channels, therefore, the oil channels of the cooling fin are reasonably arranged, staggered mixed flowing of the cold oil and the hot oil is avoided, and the heat conduction efficiency of the cooling fin is improved.

Description

technical field [0001] The present invention relates to the technical field of home appliances, and more specifically, to a heat sink and a heat sink with the same. Background technique [0002] In the related art, the radiator usually includes a plurality of cooling fins, and each cooling fin defines a plurality of oil passages, and the oil flow direction in each oil passage is chaotic and disorderly. In the same oil passage, high-temperature oil flows upwards, and low-temperature oil flows downwards. The heat conduction efficiency of the entire heat sink is low, and the heat dissipation effect is poor. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems at least to a certain extent. [0004] Therefore, the present invention proposes a heat sink with high heat conduction efficiency. [0005] The present invention also proposes a heat sink with the above-mentioned heat sink, and the heat conduction efficien...
