Novel integrated flat-plate solar collector board core and manufacturing method thereof

Abstract

The invention discloses a novel integrated flat-plate solar collector board core which comprises a panel A, a panel B and a backboard. A high polymer material layer A and a high polymer material layer B are arranged between the panel A and the panel B. A refrigerant heat absorption passage, a refrigerant inlet passage and a refrigerant outlet passage, which constitute a structure similar to an integrated circuit, are arranged between the high polymer material layer A and the high polymer material layer B. A thermal insulating layer and the backboard are sequentially arranged on the rear sides of the refrigerant heat absorption passage and the panel B. The cross sections of the panel A, the panel B and the refrigerant heat absorption passage are saw-toothed. The invention further discloses a manufacturing method of the novel integrated flat-plate solar collector board core. The high polymer material layer A is attached to the high polymer material layer B by adopting a hot melting method. The novel integrated flat-plate solar collector board core and the manufacturing method have the beneficial effects of realizing integrated arrangement, being low in manufacturing cost, high in sealing performance, and long in service life, and being suitable for different latitude environments.

Description

technical field [0001] The invention relates to a flat solar heat collector, in particular to a novel integrated flat solar heat collector plate core and a manufacturing method thereof. Background technique [0002] The core component of a solar water heater is a solar heat collector. A solar heat collector is a device that absorbs solar radiation and transfers the generated heat energy to a heat transfer medium. It is a special heat exchanger. The working fluid in the heat collector and The distant sun conducts heat exchange, and after adding circulation pipes and heat preservation water tanks, it becomes able to absorb solar radiant heat and raise the water temperature. [0003] The heat-absorbing plate of the traditional solar collector is a planar structure. In order to meet the sunlight, the shell of the solar collector is usually installed obliquely, that is, there is a certain angle with the vertical surface. When installed on the outside of the balcony or window sil...
