Product Description
Xiangtan Xiangke DRL-V Thermal Flow Multifunctional Thermal Conductivity Tester Interface Thermal Resistance Tester
I. Overview
The thermal conductivity meter mainly tests the thermal resistance of thin thermal conductors, thermally conductive silicone sheets, thermally conductive resins, beryllium oxide ceramics, aluminum oxide ceramics and other small materials, as well as the contact thermal resistance at the solid interface and the thermal conductivity of the materials. The materials to be tested are generally solid sheet-like materials. With the addition of a frame, powder and paste materials can also be tested.
Instrument reference standards: MIL-I-49456A (insulating sheets, thermally conductive resins, thermally conductive glass fiber reinforced); GB 5598-2015 (Determination method of thermal conductivity of beryllium oxide ceramics, rod axis method); ASTM D5470-12 (Test standard for thermal performance of thin thermally conductive solid electrical insulating materials), GB/T38712-2020 (Experimental method for thermal conductivity of ultra-thin glass, thermal flow method), GB/T29313-2012 Test method for thermal conductivity of electrical insulating materials, etc.
The instrument has automatic pressurization, automatic thickness measurement, and fully automatic computer measurement and control functions.
The DRL-V instrument is developed on the basis of the DRL-III instrument and has the following characteristics:
A protective thermal device is added around the test rod in the test head (this device can provide thermal protection for the sample), which expands the test temperature range of the instrument and reduces the influence of ambient temperature on the test.
A thermocouple stack with temperature difference for heat flow measurement is added to the test rod in the test head, which improves the resolution, accuracy and repeatability of heat flow measurement.
The ice-water mixture for cold-end compensation of the thermocouple is cancelled, simplifying the operation and making it easier to use.
Added experimental methods such as "aging reliability test", "high thermal conductivity material test", and "sample-to-sample contact thermal resistance test".
DRL-3 and DRL-5 instruments can be widely used in colleges and universities, scientific research units, quality inspection departments and manufacturing plants for material thermal analysis and testing.
