Embodiment 1

[0013] The present embodiment has the solar water heater of replenishing fluid cooling function as figure 1 and figure 2 Shown, including collector and storage tank.

[0014] The heat collector is composed of a header 12 communicated with a group of substantially horizontal heat collecting vacuum tubes 2 and a U-shaped heat exchange tube 13 arranged in the header 12 . The header 12 of the heat collector has a replenishment port A and a return port B. Two ports of the U-shaped heat exchange tube 13 protrude from the header 12 as the inlet and outlet of the circulating fluid respectively.

[0015] The hot water storage tank 14 has a water inlet D, a water outlet C, a water inlet E and a water return F. The inlet and outlet of the circulating fluid of the U-shaped heat exchange tube are respectively communicated with the water return port E and the water inlet F of the hot water storage tank, forming a heat exchange circulation loop.

[0016] In addition, it also contains he...

Abstract

The invention relates to a solar water heater, which belongs to the technical field of solar application. The water heater comprises a collector and a hot water storage tank, wherein the collector is provided with a fluid supply port and a reflux port. The solar water heater is characterized by comprising a fluid supply radiation tank; the fluid supply radiation tank is provided with a water supply inlet, a fluid supply inlet and a reflux inlet higher than the fluid supply port, and the upper part of the fluid supply radiation tank is provided with an exhaust overflow port; the water supply inlet is connected with a water source through a connection control device; and the fluid supply inlet and the reflux inlet are connected with corresponding ports of the collector respectively so as to form a heat dissipation circulation loop. The solar water heater felicitously and organically combines fluid supply and heat dissipation together so as to supply water and effectively solve the problem of overheat, thereby ensuring use safety of the solar water heater.

Description

technical field [0001] The invention relates to a solar energy utilization device, in particular to a solar water heater with liquid replenishment and heat dissipation functions, and belongs to the technical field of solar energy applications. Background technique [0002] Solar water heaters have the remarkable advantages of energy saving and environmental protection, so they have been rapidly popularized and applied. Existing solar water heaters are mainly composed of a heat collector for receiving solar energy, and a hot water storage tank for heat exchange with the heat collector through a circulation pipeline. In addition, in order to prevent the water shortage caused by the water loss of the collector, so as to avoid abnormal phenomena such as "exploding tubes" in the vacuum tubes, a liquid replenishment tank is connected to the circulation pipeline. For example, the Chinese utility model patent with application number 200720034522.9 and titled "Split Pressurized Sola...
