Description

Technical Field

[0001] The utility model relates to a testing platform, in particular to a novel water-cooling and heat dissipation testing platform with a clamping fixture. Background Art

[0002] With the rapid development of science and technology, heat dissipation technology plays an increasingly important role in electronic devices. However, there are some problems in the design of traditional water-cooled plate heat dissipation platforms, which limit their extensiveness and flexibility in practical applications. This article will analyze these problems in detail and propose some improvement solutions in order to promote the development of water-cooled plate heat dissipation platforms.

[0003] First, in the past, water-cooled cooling platforms were usually designed with a single size, which made them very inconvenient to use. Due to the different sizes and shapes of different electronic devices, it is difficult for a single cooling platform to meet diverse needs. For example, some high-performance computer servers may require a larger cooling platform to ensure a stable operating temperature, while some portable electronic devices may require a smaller and lighter cooling platform. Therefore, in order to meet the needs of different users, the cooling platform should be available in a variety of sizes so that it can be flexibly adapted to various application scenarios.

[0004] Secondly, the traditional water-cooled plate cooling platform has relatively simple functions and lacks supporting fixtures, which makes it very difficult to install, position and test samples. In actual applications, users usually need to spend a lot of time and energy to adjust and fix the cooling platform to ensure that it can fit tightly with the electronic equipment to achieve the best cooling effect. This not only increases the difficulty of operation, but may also affect the cooling effect and even cause damage to the equipment. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a novel water-cooled heat dissipation test platform with a clamp fixture. The novel water-cooled heat dissipation platform with a clamp fixture has a built-in water channel to ensure that the temperature of all parts of the platform is uniform. In addition, the platform size can be customized according to user needs to meet personalized needs. It can be used in conjunction with a wet temperature controller to control the temperature of the cold plate and provide a constant ambient temperature for the junction temperature and thermal resistance of the test device. Due to the horizontal support rod and the thermal resistance and power cycle thermal reliability test of the planar high-power semiconductor IGBT / SiCMosfet device (module), it breaks through the traditional cold plate heat dissipation size fixed mode and can be customized in different sizes, which is suitable for water-cooled plate heat dissipation scenarios of different types of devices. Clamps for different types of devices can be provided for installation, fixation and positioning of different types of test samples.

[0008] As an optimal technical solution, the horizontal support rod consists of two side metal blocks and a middle horizontal cross bar, and the side metal blocks are connected to the slide rails on both sides of the device support frame, and the middle horizontal cross bar and the two sides of the side metal blocks are fixed and locked with hexagon socket screws.

[0009] As a preferred technical solution, the vertical pressure rod is composed of a support clamp, an insulating pressure head and a vertical long metal screw. The vertical long metal screw passes through the support clamp, and the support clamp is fixed on the horizontal support rod; the insulating pressure head is installed at the bottom of the vertical long metal screw to directly contact and bear force on the surface of the positioning hole of the power device to be tested, wherein the insulating pressure head has an insulating function and can rotate freely.

[0010] As a preferred technical solution, the surface of the copper water-cooling plate is smoothed and its material is pure brass; a flow channel is arranged inside the copper water-cooling plate to make the temperature distribution on the surface uniform; a metal adapter is arranged on one side of the copper water-cooling plate, the metal adapter is connected to the flow channel inside the copper water-cooling plate, and is connected to the external water channel through the metal adapter.

[0011] As a preferred technical solution, foot pads are provided around the bottom of the device support stand.
