Abstract

The invention discloses a device for detecting the temperature difference of cap-type solar gravity heat pipes and a detection method. Water is contained in a constant-temperature water groove; a second round disc is arranged right above the center of the bottom part of the constant-temperature water groove and is arranged in the constant-temperature water groove in a supporting manner; the second round disc is higher than the water level in the constant-temperature water groove; a first round disc is arranged right above the second round disc in a supporting manner; first round holes are uniformly distributed on the first round disc at intervals; second round holes corresponding to the first round holes are uniformly distributed on the second round disc at intervals; the solar gravity heat pipes penetrate through the first round holes and the second round holes and are inserted into the constant-temperature water groove; and a temperature measuring cap is arranged right above a condensation section and is connected with a temperature round-detection instrument. The device and the detection method disclosed by the invention have the advantages that the plurality of solar gravity heat pipes can be born once, the temperature values of the condensation ends of the solar gravity heat pipes can be obtained by fully utilizing contact-type temperature detection, and a practicable method is provided for realizing automation of batched temperature-difference detection, so that the detection efficiency for the solar gravity heat pipes is improved.

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...
