Description

Air-cooled and water-cooled integrated chassis

Technical Field

The utility model relates to the technical field of test cases, in particular to an air-cooling and water-cooling integrated case.

Background

With rapid development of electronic product technology and increasing requirements on process efficiency and yield, the electronic industry increases the heat dissipation requirements on the electronic board card in the test process while increasing the process efficiency of the electronic product. Among other things, it presents a significant challenge to the heat dissipation of high power PCB boards present in the case.

The conventional test box has the following disadvantages:

first, a test box generally only has one heat dissipation mode (air cooling heat dissipation or water cooling heat dissipation), and the heat dissipation requirement of a high-power PCB board in the test process cannot be met.

Second, there is no real-time temperature monitoring of the PCB for the PCB reduces the life of the PCB due to long-term too high temperature or other factors, and creates a safety hazard.

Third, since a general test box is designed to satisfy the heat dissipation effect, a large number of fans are often added or the size of the heat dissipation fan is increased to achieve the heat dissipation effect, which greatly occupies the space of the test box and causes the test box to be unsightly.

Fourth, in existing test boxes, air-cooled heat dissipation and water-cooled heat dissipation are separated, and air-cooled water-cooled heat dissipation is not integrated into a box body, so that the heat dissipation effect of a high-power product cannot be guaranteed by only one box body, and the cost is increased.
