Example Embodiment
[0039] Example 1
[0040] like figure 1 As shown, a device for performance testing of thermoelectric devices with a wide size range includes a testing module, a data acquisition and processing module, an atmosphere control module and a data processing terminal 5 .
[0041] like figure 2As shown, the test module is used to test and collect the thermoelectric performance data of the thermoelectric device 12 to be measured under different temperature differences and atmospheric conditions. The test module includes a test chamber 11 , a constant temperature circulator 1 , a flow rate control module 2 , an inlet temperature sensor 3 , an outlet temperature sensor 4 and a circulating water cooler 8 . The flow rate control module 2 adopts a mass flow controller. The test cavity 11 is of a sealed cuboid structure and is made of 304 stainless steel; the test cavity 11 is also provided with a heating platform 9 and a cooling platform 13, and the heating platform 9 is used to provide...
Example Embodiment
[0046] Example 2
[0047] like Figure 4-Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the device for testing the performance of thermoelectric devices with a wide size range in this embodiment adopts a test platform (groove) 26, and uses an engraved groove 27 as a fixing groove to The pyroelectric device 12 is fixed in the center to enable testing of low thickness test samples.
Example Embodiment
[0048] Example 3
[0049] like Image 6 As shown, the difference between this embodiment and Embodiment 2 is that the system device used for the performance testing of thermoelectric devices with a wide size range in this embodiment uses a liquid flow meter 28 and a ball valve 29 to replace the mass flow controller, that is, the flow rate control module 2 A liquid flow meter 28 and a ball valve 29 are used.
