Abstract
The utility model relates to a ray reflecting and heat collecting device for a solar water heater. The utility model comprises a set of heat collecting pipes, and a set of corresponding ray reflecting devices and brackets for installing the ray reflecting devices arranged below each heat collecting pipe, wherein, each ray reflecting device is composed of two pieces of plane mirror glass which are symmetrically and slantingly arranged on the bracket, and an included angle between the two pieces of plane mirror glass is 50 DEG to 120 DEG. The device has the advantages of reliable and stable reflecting rays, favorable effect of heat collection, lower manufacturing cost and no maintenance, the reflecting surface can keep smooth and clean for long, the service life of the utility model can reach more than 20 years, and the utility model is suitable for solar water heaters.
Description
The utility model relates to solar water heater, relates in particular to solar water heater light reflection heat collector.
It is parabolic as reflecting surface that prior solar water heater adopts the smooth aluminium sheet of light to be processed into, thermal-collecting tube places on the paraboloidal focal axis line position of aluminium, when solar water heater uses, part light shines directly on the thermal-collecting tube, some light then shines on the aluminium parabola in addition, reflexes on the thermal-collecting tube again.The paraboloidal effect of aluminium is to increase the luminous energy that shines on the thermal-collecting tube, increases the absorption of thermal-collecting tube to luminous energy with this.The parabolic processing of this aluminium is more convenient, and manufacturing cost is lower.But solar water heater light reflection heat collector is open-air use, in wind, drench with rain, under the effect of Exposure to Sunlight, the paraboloidal surface of aluminium is progressively oxidized, makes it become intensely dark, thereby reduce its reflex gradually, reduced the Heat-collecting effect of solar water heater.
The purpose of this utility model is to provide a kind of solar water heater light reflection heat collector, and it can use out of doors for a long time, and can guarantee that the Heat-collecting effect of solar water heater is reliable and stable.
For realizing the purpose of this utility model, solar water heater light reflection heat collector, comprise one group of thermal-collecting tube, be arranged on the one group of corresponding light reflection unit in thermal-collecting tube below and the support of light reflection unit is installed, the light reflection unit adopts two level crossing surface glasses, and symmetry tilts rack-mount.
The utility model has the advantages that: this solar water heater light reflection heat collector reflection ray is reliable and stable, and Heat-collecting effect is good, and reflecting surface can keep bright and clean for a long time, and manufacturing cost is lower, can reach service life more than 20 years, and maintenance does not need repairing.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model solar water heater light reflection heat collector;
Fig. 2 is the vertical view of Fig. 1 structural representation.
As shown in Figure 1, 2, solar water heater light reflection heat collector, one group of thermal-collecting tube 4, have nine, support 1 is provided with nine " V " shape grooves 2, and the angle that is respectively arranged with in the two side of each " V " shape groove 2 between the two-way mirror 3 on two-way mirror 3, two planes on plane is 90 degree.Centre position, top at each " V " shape groove 2 is provided with thermal-collecting tube 4, and thermal-collecting tube 4 is connected with the water tank of solar water heater.
Angle between the two-way mirror 3 on two planes when 50-120 spends, the thermal-collecting tube 4 more luminous energy that can be absorbed; When angle when 80-100 spends, the luminous energy that thermal-collecting tube 4 absorbs is more; When angle when 90 spend, the luminous energy that thermal-collecting tube 4 absorbs is maximum.
When considering that light shines on the level crossing surface glass 3 that is installed on " V " shape groove 2 walls, light can be subjected to necessarily stopping of thermal-collecting tube 4, no matter light is from what angular illumination, partial mirror glass 3 is arranged at the bottom at " V " shape groove 2, can not increase absorption luminous energy to thermal-collecting tube 4 very effectively all the time and work.So, the bottom that two-way mirror 3 can not be installed to " V " shape groove 2 is installed in the sidewall of " V " shape groove 2.In addition, also the bottom of " V " shape groove 2 can be can be made into the end on plane, thereby make " V " shape groove 2 become the dovetail groove that opening makes progress.
When solar water heater uses, part light shines directly on the thermal-collecting tube 4, thermal-collecting tube 4 changes into heat energy with luminous energy, some light shines on the two-way mirror 3 from the both sides of thermal-collecting tube 4 in addition, and then reflex on the thermal-collecting tube 4, by thermal-collecting tube 4 luminous energy is changed into heat energy, thereby make the water in the thermal-collecting tube 4 obtain heating.By the Natural Circulation of water, make that the water in the solar water heater water tank constantly obtains heating.
This solar water heater light reflection heat collector, when using at noon, when promptly the light vertical irradiation was to this device, Heat-collecting effect was best; When sooner or later using, Heat-collecting effect is the poorest.
The utility model is applicable to solar water heater.
