Embodiment Construction

[0011] The first choice is to make a plastic flat collector shell 8 similar to a square box by injection molding, and plastic materials can also be assembled into a plastic flat collector shell 8 by bonding, and the insulating layer 7 is formed by filling light insulating materials inside. Transparent and water-resistant, temperature-resistant, weather-resistant plastic is used to make a hollow transparent plastic sheet with multiple small drainage pipes 2 through extrusion molding, and the inner wall of the small drainage pipe is coated with solar selective absorption. Coating 10 just becomes plastics row pipe heat-absorbing plate 6. Use plastic pipes with good temperature resistance, water resistance and weather resistance as the collecting pipe 3, use plastic plug 4 to heat-melt and seal one nozzle, and the other nozzle is thermally welded with inner wire 5 as the interface of the external heating part. On the plastic collecting pipe 3, a connection groove 11 is melted out ...

Abstract

The invention provides a plastic slab heat collector, relating to the field of solar heat collectors. High cost and inconvenient installation of the solar heat collector used as the core part for the development and utilization of the solar energy become a barrier which blocks the generalization of the solar energy utilization; furthermore, the existing plastic slab heat collector has the problem that the heat conversion efficiency is not sufficiently improved. In order to overcome the problems, the invention provides the plastic slab solar heat collector which has simple structure and light weight; by adopting a technique that an internal wall is coated by a solar absorbing layer, the plastic slab heat collector consists of a plastic slab heat collector frame, a plastic slab heat collector shell, a plastic collecting pipe, a plastic row-pipe heat absorbing plate, a light heat-preservation layer and a plastic hollow transparent cover plate, has simple structure, low manufacture cost and light whole weight, can be arranged on the roofs and balconies and walls exposed to the sun, and can be generalized in the urban in large areas.

Description

[0001] field; [0002] The invention relates to the field of solar heat collectors, in particular to a plastic flat solar heat collector with simple structure and light weight. Background technique; [0003] At present, renewable energy has been included in the country's medium and long-term development plan, and the development and utilization of household solar thermal energy has also received more and more attention. As the core component of domestic solar thermal energy development and utilization, the high cost and inconvenient installation of solar collectors have become obstacles to the popularization of solar thermal utilization. Existing solar heat collectors are divided into heat collecting tube type and flat plate type according to shape. The existing heat collecting tube type heat collector has high thermal efficiency of a single tube, but the overall weight of multiple tubes, inconvenient installation, and high production cost can only be adapted for roof install...
