Frequency converter heat pipe radiator

Abstract

The invention discloses a frequency converter heat pipe radiator which comprises a radiating bottom plate, radiating fins and heat pipes. A plurality of inserting connection grooves are parallelly formed in the surface of the radiating bottom plate, the radiating fins are connected in the inserting connection grooves in an inserted manner, inserting connection ends of the radiating fins are in interference fit with the inserting connection grooves, in addition, heat pipe grooves are formed in the radiating bottom plate and perpendicular to the inserting connection grooves, the inserting connection ends of the radiating fins are provided with fastener grooves at the corresponding positions, and the heat pipes are connected in the heat pipe grooves in a fastened manner. The radiating fins are provided with same structures, single-model mass production of the radiating fins can be realized, production efficiency is improved, production difficulty is reduced, in addition, the grooves are formed in the radiating bottom plate, the arrangement difficulty of the heat pipes is reduced, heat resistance of the heat pipes and the radiating bottom plate is reduced, radiating efficiency is improved, heat pipe penetrating holes are formed in the radiating fins, and the radiating efficiency can be further improved.

Description

technical field [0001] The invention relates to a heat pipe radiator, in particular to a heat pipe radiator for a frequency converter. Background technique [0002] The working principle of the radiator is: the heat dissipation fins are combined with the heat pipe, the base and the heat source that needs to be dissipated, and then cooperate with the active cooling component and the auxiliary conduction of the heat dissipation device to dissipate heat from various heat sources. A large-area heat dissipation combination is formed. [0003] At present, the radiators for frequency converters on the market are basically composed of bases, heat pipes and heat sinks. One form is that the heat pipes are connected to the base by brazing, and the other is that the heat pipes are fixed on the base plate by bolts. The first fixing method is likely to cause an intersection angle greater than 90 degrees between the heat sink and the heat pipe, resulting in non-uniform structure of the he...

AI Technical Summary

Problems solved by technology

The first fixing method is likely to cause an intersection angle greater than 90 degrees between the heat sink and the heat pipe, resulting in inconsistent structure of the heat sink, which increases the difficulty of processing and production costs

The second fixing method significantly increases the thermal resistance between the base and the heat pipe, resulting in a decrease in the thermal efficiency of the heat pipe radiator
