A solar water heater for heating liquid medicine

Abstract

The invention provides a solar water heater. A heat collector is included and comprises heat collecting pipes and a water tank. Each heat collecting pipe comprises an evaporation end and a condensation end, wherein the condensation end is arranged in the water tank, the evaporation end absorbs solar energy, the condensation end is used for transmitting heat into water in the water tank, and the condensation end is located at the upper portion of the evaporation end. From the lower portions of the heat collecting pipes to the upper portions of the heat collecting pipes, a plurality of flow homogenizing pipes are arranged between the adjacent heat collecting pipes, the adjacent heat collecting pipes are in communication. At the evaporation ends, from the lower portions of the heat collectingpipes to the upper portions of the heat collecting pipes, the diameters of the flow homogenizing pipes are constantly increased. According to the solar water heater, since fluid constantly absorbs heat along with upward flowing of fluid, along with constant heat absorbing of the fluid, the pressures in the different heat collecting pipes are more uneven, and through the above arrangement, it canbe guaranteed that pressure balance can be reached as fast as possible in the fluid flowing process.

Description

technical field [0001] The invention belongs to the field of solar energy, in particular to a solar heat collector. Background technique [0002] With the rapid development of modern society and economy, the human demand for energy is increasing. However, the reserves of traditional energy such as coal, oil, and natural gas continue to decrease and become increasingly scarce, resulting in rising prices. At the same time, the environmental pollution caused by conventional fossil fuels is also becoming more and more serious. These greatly limit the development of society and the improvement of human life quality. . Solar thermal conversion is a solar energy utilization method with high energy conversion efficiency and utilization rate and low cost, which can be widely promoted in the whole society. In solar heat utilization devices, the key is to convert solar radiation energy into heat energy, and the device that realizes this conversion is called a solar collector. [000...

AI Technical Summary

Problems solved by technology

During the evaporation process of the heat pipe, it will inevitably carry liquid to the steam end. At the same time, because of the exothermic condensation of the condensation end, there will be liquid in the condensation end, and the liquid will inevitably mix with the steam, so that the fluid in the heat pipe is vapor. Liquid mixture, the existence of vapor-liquid mixture causes the gas to mix together, and the heat exchange capacity between the liquid and the liquid decreases, which greatly affects the heat exchange efficiency
