Problems solved by technology

When debugging the memory DC-DC circuit, it is necessary to insert 6 test fixtures in a group of memory slots, but due to the existence of heat sinks on each test fixture, the adjacent test fixtures in the memory slot The gap is narrower, the gap will be as low as 1mm, so that the heat dissipation ability of the metal heat sink is reduced
[0003] However, when a load is added to the test fixture, the temperature of the test fixture will gradually increase due to the low heat dissipation capacity of the metal heat sink on the test fixture, and the test fixture needs to control the temperature within a certain range during testing to obtain Accurate value, so when the temperature is too high, the test fixture will trigger the over-temperature protection, and finally the test cannot be carried out

Abstract

The invention discloses a cooling device. The cooling device comprises a plug, a first fan set, a second fan set, a first wind shield and a second wind shield. By means of the cooling device, the first fan set blows cold air into a test fixture; the second fan set discharges heat emitted by the test fixture through hot air; the test fixture is cooled; the temperature of the test fixture is controlled within a certain range; and over-temperature protection caused by the over-high temperature of the test fixture is prevented.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a cooling device. Background technique [0002] Intel memory VRTT is a test fixture released by Intel specifically for server memory DC-DC circuits. The IntelmemoryVRTT test fixture has a golden finger structure, and each test fixture has an additional metal heat sink. When debugging the memory DC-DC circuit, it is necessary to insert 6 test fixtures in a group of memory slots, but due to the existence of heat sinks on each test fixture, the adjacent test fixtures in the memory slot The gap is narrower, and the gap can be as low as 1mm, so that the heat dissipation ability of the metal heat sink is reduced. [0003] However, when a load is added to the test fixture, the temperature of the test fixture will gradually increase due to the low heat dissipation capacity of the metal heat sink on the test fixture, and the test fixture needs to control the temperature within a certain...
