Description

Broken-line heat-absorbing flow channel of balcony-type flat solar collector

technical field

The utility model relates to a broken-line heat-absorbing flow channel of a balcony-type flat solar heat collector.

Background technique

At present, the lighting surface of the balcony-type flat solar collector has a flat outline shape, and the flow channel structure of the heat absorbing body has the following two types:

1. A vertical riser tube is adopted, and there are two long headers up and down. At the same time, a section of downcomer is added to the lower header for the side-by-side replacement of the external interface. This method consumes a lot of precious metals, and at the same time, there are too many riser tubes, the structure is complicated, the solder joints increase, and the product cost is increased, and it can only be used in one direction;

2. The horizontal flow channel is adopted, the left and right headers are used for up and down flow diversion, and there are multiple horizontal flow channels in the middle. In order to adapt to the balcony installation and realize the side-by-side liquid exchange of the external interface, this structure also needs to be installed in the collector Adding extension pipes to the header at the other end or laying circulation pipes outside the collector will also increase the consumption of precious metals, and due to the interference of the medium flow direction and heat convection direction in the lateral flow channel, it will affect the heat exchange and application range. There will be a certain impact, thereby reducing thermal efficiency.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a new folding line heat-absorbing flow channel of a balcony-type flat solar collector, which achieves a reasonable horizontal rise, saves the length of the header and can be used in both directions. .

The technical solution adopted by the utility model to solve the technical problem is: the folding line heat-absorbing flow channel of the balcony-type flat solar collector, there is a heat-absorbing plate in the frame of the heat-collector, and there is a baffle header at one end of the heat-absorbing plate, The other end has an outlet header and an inlet header, with a plug in the middle, an outlet joint on the upper end, and an inlet joint on the lower end. The flow tube and the riser tube of the folded flow channel are respectively inclined to both sides and arranged symmetrically in a transverse V shape.

The utility model can be used on the heat absorbing body of the flat plate solar heat collector on the balcony. The heat collector is installed on the balcony or the south wall. When working, the flow channels on both sides of the horizontal V-shaped flow channel, the external pipeline and the water tank together form a complete cycle. In the pipeline, the heat conduction circulating medium enters the inlet header from the inlet joint passing through the collector frame, and then enters the riser pipe of the folded front flow path with a certain rising slope, and enters the baffle header, and then enters the riser pipe with a certain rise. The riser pipe of the folded flow path of the slope finally enters the outlet header, flows out from the outlet joint and enters the external pipe.

For the structural type with upper and lower interfaces, the collector can place the interface east or west.

The beneficial effects of the utility model are: (1) the material used for the header is greatly saved; (2) the direction of the heat flow in the upflow tube is consistent with that of the medium, and the heat transfer effect is improved; (3) the number of upflow tubes is small, the structure is simple, and the welding The number of points is reduced; (4) It can be used flexibly in the east-west direction.
