Abstract

The invention discloses a solar capillary temperature gradient box, and relates to the technical field of solar heat collection. The temperature gradient box comprises a solar heat collector, a temperature control water tank, a low temperature water tank, a test box and a controller, wherein a heating coil pipe and a cooling coil pipe are arranged in the temperature control water tank. The test box comprises a heat preservation barrel body and an upper cover, wherein an annular wall type capillary heat exchanger and a metal inner barrel are coaxially arranged in the heat preservation barrel body from outside to inside, the annular wall type capillary heat exchanger comprises an upper ring tube, a lower ring tube and a capillary tube used for communicating the upper ring tube and the lowerring tube, and a water outlet tube and a water inlet tube are respectively arranged on the upper ring tube and the lower ring tube. The solar heat collector is connected with the heating coil pipe toform a first circulation loop; and the low temperature water tank and the cooling coil pipe form a fourth circulation loop, and the temperature control water tank is connected with the annular wall type capillary heat exchanger to form a third circulation loop. The annular wall type capillary heat exchanger is used for heat exchange, the solar capillary temperature gradient box has the characteristics of a large heat exchange area and a small heat exchange temperature difference, and the rapid temperature change and uniform temperature distribution in the box can be realized.

Description

technical field [0001] The invention relates to the technical field of solar heat collection, in particular to a solar capillary temperature gradient box. Background technique [0002] The temperature gradient box is an ideal equipment for scientific research and production in the fields of biology, food engineering, medical research, agriculture and forestry science, aquatic products, and animal husbandry. In order to more correctly simulate the actual environmental conditions that the product is subjected to in nature, it is necessary to ensure that the tested product is under the same temperature and environmental conditions in the environmental test. For this reason, the temperature gradient and temperature fluctuation in the test chamber must be limited. . [0003] The temperature stability and uniformity inside the test chamber is an important indicator to measure the performance of the temperature gradient chamber, and the rapid conversion of different temperature gr...
