Abstract

The utility model relates to a vacuum pipe solar energy steam heat collector which is composed of a vacuum pipe, a reflecting plate, a framework, a gas storage tank and a bracket. The gas storage tank is an empty tank body with small volume, the bottom of the gas storage tank is communicated with the vacuum pipe, and both sides of the gas storage tank is provided with a pipeline which can be used for water entering and gas transporting. The inner part of the vacuum pipe and the bottom of the gas storage tank are poured with softened water at stationary state, and hot steam is stored in the gas storage tank at working state. The utility model changes aqueous medium into gas medium, and steam transport has the advantages of big head loading quantity, fast heat transport, little heat waste and high heat effect. The utility model can directly introduce steam in living rooms for using by the pipeline, and the utility model not only can heating a water tank and steam cookers and steam rice, but also has the advantages of small gas storage tank, small occupation of land and convenient installation.

Description

Vacuum pipe solar steam heat collector

The utility model belongs to a kind of solar energy heat utilization device, relates to a kind of vacuum pipe solar steam formula heat collector.

The solar vacuum-tube use device no matter be water heater, or boiler is a heat transfer medium with water all at present, and the deficiency of being brought is: intensification is slow, heat waste is big, easy fouling during the heating boiling water, and the bad removing of incrustation.In addition owing to be heat transfer medium with water, the water in the vacuum tube by solar energy heating after, need leave in the storage tank, for using at any time, so require compact water storage tank bigger, both heavy, waste material again.Owing to adopt the water circulation, if heat collector and water tank split must be provided with circulating water pipe up and down, heat energy loss is big like this, and aqueduct easily bursting by freezing in the winter time." solar cooker " that has come out is with its health, energy-conservation and be subjected to the welcome of energy scarcity area family.But have to kitchen range are installed on the heat collector, cook under the sunlight in the open, cooking is very arduous.

The purpose of this utility model is a kind of vacuum pipe solar steam formula heat collector of design, and it changes the deficiency of above heat collector, makes further progress in the field of vacuum pipe solar utilization.

The purpose of this utility model realizes by following scheme: vacuum tube solar heating element is made up of vacuum tube, reflecting plate, framework, expansion box and support, described expansion box is a sylphon body, its volume is little, the bottom is connected with vacuum tube one by one, appendix is equipped with in the expansion box both sides, this appendix can be general with water inlet pipe, when static, in the vacuum tube and expansion box bottom is marked with demineralized water, vacuum tube absorbs sunlight during duty, after boiling, steam is full of expansion box, enters steamer or water tank by appendix with the heating of the water in the pipe.

Advantage of the present utility model is: this heat collector is that aqueous medium is become gas medium, and steam is hot big than water ballast, and it is fast to conduct heat, so heat waste is little, and thermal efficiency height.Owing to adopt the steam transmission, heat steam can be introduced indoorly, not only can heat water for bathing, also can indoorly boil water, steamed rice, can prevent that pipeline from freezing winter simultaneously.Storage tank with heaviness changes small and exquisite expansion box in addition, and whole heat collector is had attractive appearance, and is easy for installation.

Fig. 1 is a shape schematic diagram of the present utility model

Fig. 2 is the key diagram of a kind of embodiment in the utility model

Fig. 3 is the key diagram of another kind of embodiment in the utility model

Be described as follows below in conjunction with drawings and the specific embodiments:

In Fig. 1, vacuum pipe solar steam formula heat collector is made up of vacuum tube 1, reflecting plate 2, framework 3, expansion box 4, support 5, described expansion box 4 is a sylphon body, the more existing storage tank of its volume is little, the bottom is connected with vacuum tube 1 one by one, the expansion box both sides are connected to appendix 6, and this appendix also is used as water inlet pipe and is used.In the vacuum tube 1 and expansion box bottom is marked with demineralized water.When devoting oneself to work, demineralized water becomes steam and is stored in the expansion box 4.

Fig. 2 is " ground type " solar energy steam heater that is applicable to that one-storey house or house are installed, and it is to be installed in the institute or the roof with solar thermal collector is vertical.During use, 1 pair of sun of the vacuum tube of heat collector has accurate tracing property, and solar energy rises to boiling with the heating of the cold water in the vacuum tube.Vapours then rises in the expansion box 4, during use, opens the valve 7 on the appendix 6, and vapours enters steamer 8 by appendix, thereby the rice in the pot is cooked; Heat steam also can enter water tank 9 by pipeline, the heating of the water in the water tank, uses for shower.

Fig. 3 is the balcony formula solar energy steam heater that is applicable to that building is installed, and it is to be installed on the balcony solar thermal collector is horizontal.Occupation mode is to utilize solar energy that the heating of the water in the vacuum tube is become steam with above-mentioned the same equally, and steam is sent in steamer 8 or the water tank 9 along pipeline 6, utilizes heat steam to add hot water or steamed rice.

Because steam heat-carrying is big, it is fast to conduct heat, and can reach the inaccessiable effect of water ballast heat.

Claims

1, a kind of vacuum pipe solar steam heat collector of forming by vacuum tube, reflecting plate, framework, expansion box and support, it is characterized in that: described expansion box (4) is a sylphon body, the bottom is communicated with vacuum tube (1), both sides are equipped with and are can be used for the into pipeline (6) of water and gas transmission, and in the vacuum tube (1) and expansion box (4) bottom is marked with demineralized water.
