Problems solved by technology
At this stage, most manufacturers of solar gravity heat pipes complete the temperature difference detection manually. Due to the large human factors, large empirical errors, and high labor intensity in manual verification, errors are unavoidable.
At this stage, the loading device for solar gravity heat pipe verification does not exist on the market, and the current solar gravity heat pipe temperature difference measurement method adopts single non-contact measurement and contact measurement, and its measurement efficiency is extremely low. Therefore, a method that can measure batches The way of solar gravity heat pipe temperature difference

The invention discloses a device and a detection method for detecting the temperature difference of a cap-type solar gravity heat pipe. The constant temperature water tank is filled with water, the second disc is installed directly above the center of the bottom of the constant temperature water tank, and is supported and installed in the constant temperature water tank, the second disc is higher than the water surface in the constant temperature water tank, and the first disc is supported and installed on the second disc Directly above the first disc, there are first round holes evenly distributed on the first disc, and second round holes corresponding to the first round holes are evenly distributed on the second disc; the solar gravity heat pipe passes through the first round holes , The second round hole is placed behind the constant temperature water tank, a temperature measuring cap is installed directly above the condensation section, and the temperature measuring cap is connected with the temperature inspection instrument. The invention can hold multiple solar gravity heat pipes at one time, and can make full use of contact temperature measurement to obtain the temperature value of the condensation end of the solar gravity heat pipe, which provides a feasible method for realizing the automation of temperature difference verification in batches, thereby improving the efficiency of the solar gravity heat pipe. the testing efficiency.
Description
technical field [0001] The invention relates to a heat pipe detection device and method, in particular to a cap-type solar gravity heat pipe temperature difference detection device and detection method. Background technique [0002] Due to the advantages of strong thermal conductivity, small heat loss, anti-freezing, and no tube explosion, solar gravity heat pipes are becoming more and more common in solar heat utilization. In order to ensure the heat transfer efficiency of the solar gravity heat pipe, it is necessary to detect the technical requirement of the temperature difference of the solar gravity heat pipe. At the present stage, most manufacturers of solar gravity heat pipes complete the temperature difference detection manually. Due to the large human factors, large empirical errors, and high labor intensity in manual verification, errors are unavoidable. At this stage, the loading device for solar gravity heat pipe verification does not exist on the market, and the...
