ある。(b) Conventional technology Conventionally, a solar heat collector main body is composed of a heat pipe type heat collector consisting of a heat collecting part and a heat radiating part, and a hot water storage tank into which the heat radiating part is inserted, and the inside of the hot water storage tank is A technique for improving heat collection efficiency by promoting convection in the tank by driving the stirring means to improve heat exchange between the heat radiating section and the water is disclosed in Japanese Utility Model Publication No. 53-18916. It is publicly known.

悪いという欠点があった。According to the configuration of the device described in this document, the stirring means is located above the heat collecting part and discharges the water in the upper part of the hot water storage tank downward. Since the heat exchanger exchanges heat with the heat collecting part, a temperature difference cannot be maintained, and since the entire inside of the tank is stirred, the flow rate in the heat collecting part is low, resulting in poor heat exchange efficiency.

温度差がとれると共に集熱部付近の流速が速（なる。Function: When the pump is driven by the above means, low-temperature hot water at the bottom of the tank is sucked in from the suction pipe and vigorously discharged from the discharge pipe toward the heat collecting section, causing the hot water to exchange heat with the heat collecting section. The temperature is low and the temperature difference is removed, and the flow velocity near the heat collecting part increases.
