Embodiment 1

[0025] see figure 1 As shown, the present invention provides a flat plate heat collector 10 with a vein-shaped flow channel, including a heat absorber 20, an absorbing coating, a heat insulation layer, a cover plate and a frame, wherein the frame is used for fixing and installing the heat absorber 20 , heat insulation layer, cover plate; the heat insulation layer is arranged under the heat absorber 20, in order to prevent the heat absorber 20 from dissipating heat to the surrounding environment through conduction; the cover plate is arranged on the top of the heat absorber 20; in addition, the absorbing coating Coated on the heat absorber 20 to absorb solar radiation energy to the greatest extent and convert it into heat energy. The heat absorber 20 includes a first header 21, a second header 22 and a branch pipe 23, the second header 22 is spaced apart from the first header 21; the branch pipe 23 is connected to the first header 21 and the second header 22 Between them, the ...

Embodiment 2

[0038] see figure 2 As shown, the difference between the second embodiment and the first embodiment is that the heat absorbing plate 20a of the first embodiment has a rectangular structure, while the heat absorbing plate 20a of the second embodiment has a triangular structure. Among them, the rectangular structure is not only easy to manufacture and saves materials, but also in the case of the same material, the rectangular structure is larger than the general geometric area, for example, its area is larger than the circular structure, so its corresponding absorption area will also larger. However, the triangular structure of this embodiment has the characteristics of better stability and is suitable for installation in narrow places. In general, whether the heat absorbing plate 20a is made into a rectangular structure or a triangular structure is mainly determined based on the actual needs of users and the installation environment, but the structure of the heat absorbing pl...

Abstract

The invention provides a flat plate heat collector with vein-shaped runners. The flat plate heat collector with the vein-shaped runners comprises a heat absorption body, wherein the heat absorption body comprises a first collection pipe, a second collection pipe and a branch pipe, the second collection pipe and the first collection pipe are arranged at an interval, the branch pipe is arranged between the first collection pipe and the second collection pipe in connection mode, the branch pipe is provided with a shunting area used to shunt heat absorption mediums and a converging area used to converge the heat absorption mediums, at least two shunting runners arranged in vane shape are arranged between the shunting area and the converging area, starting ends of the at least two shunting runners are arranged on the shunting area and arranged in intersection mode so as to form shunting points, and tail ends of the at least two shunting runners are arranged on the converging area and arranged in intersection mode so as to form intersection points. According to the flat plate heat collector with the vein-shaped runners, the heat absorption mediums can evenly absorb heat by arranging the at least two shunting runners arranged in vane shape on the branch pipe, and accordingly heat absorption efficiency of the flat plate heat collector with the vein-shaped runners can be improved, and furthermore the fact that instantaneous efficiency of the flat plate heat collector is larger than or equal to 0.8 is guaranteed well.

Description

technical field [0001] The invention relates to the field of solar flat plate heat collectors, in particular to a flat plate heat collector with vein-shaped flow channels. Background technique [0002] Flat-plate collectors are the basic components of low-temperature solar heat utilization, and have always been the leading products in the world solar market. Flat plate collectors have been widely used in domestic water heating, swimming pool heating, industrial water heating, building heating and air conditioning and many other fields. The flat plate collector is mainly composed of heat absorber, transparent cover plate, heat insulation layer and shell. Specifically, the flat plate collector is a device that absorbs solar radiation energy and transfers heat to the working medium. It is a special heat exchanger, and the working medium in the heat collector exchanges heat with the distant sun. [0003] However, for the flat-plate collectors in the current market, their heat ...
