Capillary network solar energy acquisition system

Abstract

The invention discloses a capillary network solar energy acquisition system. The capillary network solar energy acquisition system comprises a water tank, a water inlet main pipe and a water return main pipe, wherein the water inlet main pipe is provided with a water pump, and is characterized in that the water inlet main pipe and the water return main pipe are jointly connected with a distribution manifold, the water tank is provided with a heat pump connected with the distribution manifold, a plurality of solar thermal collectors are arranged in parallel on the distribution manifold, each solar thermal collectors comprises two headers and a plurality of capillary pipes connected between the headers at intervals, and the two headers are provided with a water inlet pipe and a water returnpipe respectively which are connected with the distribution manifold. According to the technical scheme, due to the flexible characteristics of the capillary pipes, the capillary network solar thermalcollectors can be integrated in a cement board and can also be integrated in an aluminum alloy plate, and can be directly radiated on an outer wall, the installation is simple, the distance among thecapillary pipes is small, the heat exchange area is large, and the heat exchange capability is relatively high.

Description

technical field [0001] The invention relates to the technical field of solar heat collection, more specifically, it relates to a capillary network solar energy collection system. Background technique [0002] Solar water heater is a device that converts sunlight energy into heat energy, and collects heat from low temperature to high temperature to meet the needs of hot water in people's life and production. Since solar energy is a green and environmentally friendly energy source that does not produce any pollution, it has been vigorously advocated by the country, and the application of solar water heaters has also been popularized. [0003] Traditional solar collectors use coated solar collectors to absorb solar energy to increase water temperature and obtain hot water for heating or domestic hot water in winter, but traditional solar collectors have small laying area, small heat exchange area, and unit The area cost is high, the integration is poor, and the construction me...
