The invention provides a testing device for all-glass gravity assisted heat pipes, belongs to the technical field of machinery and solves technical problems that testing devices cannot be applied to heat pipes with two ends closed, are small in application range and the like due to the fact that heating rods are required to be placed inside the heat pipes in the prior art. The testing device for the all-glass gravity assisted heat pipes comprises a body, a cover, a heating part and a support, wherein a concave heating cavity is formed in the body, the support is fixedly connected to the bottom of the heating cavity and provided with a positioning notch for positioning the heat pipes, a perforation communicated with the heating cavity is formed in one side of the body, the heating part is located at the bottom of the heating cavity, the cover is hinged to the body, and the heating cavity can be opened or closed after the cover swings around hinged positions of the cover. The testing device has the advantages of intuitiveness in observation and even heating.
Description
technical field [0001] The invention belongs to the technical field of machinery and relates to a test device, in particular to a test device for an all-glass gravity heat pipe. Background technique [0002] The heat pipe is the core component of the solar water heater. Heat the heat pipe to 350°C. After 48 hours of high-temperature aging test, the quality of the heat pipe can be judged by observing the mirror disappearance rate of the getter. The quality directly affects the thermal performance of the water heater. [0003] After searching, for example, Chinese patent literature discloses a high-temperature baking test device for all-glass vacuum solar collector tubes [Patent No.: ZL200920272928.X; Authorized Notice No.: CN201600236U]. This all-glass vacuum solar collector tube high-temperature baking test device includes a heat collector inner tube and a heat collector outer tube. Aluminum tube, one end of the aluminum tube is inserted into the bottom of the inner tube of...
