Totally-sealed cooling chamber

Abstract

The invention relates to a totally-sealed cooling chamber. The totally-sealed cooling chamber comprises a lower chamber (1), an upper chamber (2), a locking block (5) and a reinforcing coaming (6), wherein a lower chamber cooling channel (3) is formed in the lower chamber (1), while an upper chamber cooling channel (4) is formed in the upper chamber (2); the lower chamber cooling channel (3) and the upper chamber cooling channel (4) are combined to form a cooling channel; a plurality of T-shaped holes (7) are symmetrically formed in the lower chamber (1) and the upper chamber (2), respectively; the T-shaped holes (7) are filled with an aluminum alloy by use of a die-casting die and a die-casting process so that locking blocks (5) can be formed; the lower chamber (1) and the upper chamber (2) are integrally and closely locked together by use of the locking blocks (5); the reinforcing coaming (6) is die-casted on the edges of the four sides of the lower chamber (1) and the upper chamber (2) by use of the die-casting die and the die-casting process. The totally-sealed cooling chamber has the advantages of good sealing effect, good inter-fusibility, short production period and suitability for large-batch production.

Description

technical field [0001] The invention relates to the technical field of manufacturing heat dissipation devices used in the working process of electronic components, in particular to a fully sealed heat dissipation cavity. Background technique [0002] Any electronic device has a certain loss during operation, and most of the loss becomes heat. Low-power devices have small losses and do not need a heat sink, while high-power devices have large losses. If no heat dissipation measures are taken, the temperature of the device may reach or exceed the allowable junction temperature, and the device will be damaged. Therefore, a heat dissipation device must be added. The most commonly used is to install the power device on the radiator, and use the radiator to dissipate the heat to the surrounding space. If necessary, add a cooling fan to enhance cooling and heat dissipation at a certain wind speed. Flowing cold water cooling plates are also used on the power devices of some large-s...

AI Technical Summary

Problems solved by technology

This production method has the defects of long cycle, high cost and low reliability

After the heat dissipation cavity is used for a period of time, gaps are likely to appear between the upper cavity and the lower cavity, resulting in leakage of cooling liquid, which affects the service life of the heat dissipation cavity
