Abstract
The utility model relates to a solar heat-collecting vacuum tube, which comprises a glass vacuum tube body and a metal heat-absorbing plate which is arranged in the vacuum tube body and is connected with an external heating device through a heat-conducting device, and is characterized in that the front and the back of the heat-absorbing plate are both provided with selective absorbing coatings. When the utility model discloses a back sets up the spotlight ware when, the utility model discloses not only can absorb the direct irradiation to the positive sunlight of absorber plate, can absorb the sunlight on reflecting the absorber plate from the spotlight ware moreover well to greatly improve the utility model discloses a collecting efficiency.
Description
The utility model relates to a kind of solar energy heating vacuum tube.
General solar energy heating vacuum tube comprises a glass-vacuum tube and is arranged on the interior plate shaped metal absorber plate of glass-vacuum tube, is provided with selective heat absorbing coating in the front of absorber plate, in order to absorbing the sunshine that is radiated on the absorber plate better.But, because traditional vacuum tube collector does not generally use concentrator, therefore, it is better that this vacuum tube absorbs for the sunshine of direct irradiation on absorber plate, yet continuous development along with the solar energy heating technology, use various concentrator on vacuum tube solar heating element more and more, therefore, traditional solar energy heating vacuum tube remains further to be improved.
The purpose of this utility model provides the higher solar energy heating vacuum tube of a kind of collecting efficiency.
For achieving the above object, the utility model is taked following design: a kind of solar energy heating vacuum tube, it comprises glass evacuated body and is arranged in the described vacuum body and by the metal absorber plate that heat-transfer device is connected with extraneous heating device, it is characterized in that: the front and back at described absorber plate all is provided with coating for selective absorption.
In order to absorb heat better, the cross sectional shape of described absorber plate can be arranged to convex semicircular arc, perhaps to recessed semicircular arc.Also can still adopt plate shaped.
The utility model is owing to the positive and negative at absorber plate all is provided with coating for selective absorption, therefore when concentrator being set at back of the present utility model, the utility model not only can absorb the sunshine that shines directly into the absorber plate front, and can absorb by the coating for selective absorption that is arranged on the absorber plate back side from concentrator and reflex to sunshine on the absorber plate, thereby greatly improved collecting efficiency of the present utility model.The utility model has further improved collecting efficiency of the present utility model owing to being arranged to absorber plate convex or to recessed semicircular arc, therefore can strengthening the plate body area of absorber plate, that is strengthen the absorber plate area simultaneously.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation
Fig. 2 is the utility model embodiment two
Fig. 3 is the utility model embodiment three
As shown in Figure 1, the utility model comprises glass evacuated body 1 and the absorber plate 2 that is arranged in the glass evacuated body 1, remainder of the present utility model all is a prior art as the heat-transfer device that is connected with extraneous heating device and the gripping mechanism of absorber plate 2, just gives unnecessary details no longer one by one at this.Feature of the present utility model is, at the front and back of absorber plate 1 coating for selective absorption 3,4 is set all.Like this when below the utility model vacuum body 1, concentrator being set, not only the sunshine of direct irradiation on absorber plate 2 can be absorbed by absorber plate well, and reflexes to the selective coating 4 that sunshine on the absorber plate also can be set at the absorber plate back side from concentrator and absorb.
In the foregoing description, in order to strengthen the area of absorber plate 2, to improve caloric receptivity, the cross sectional shape of absorber plate 2 can be taked convex semicircular arc (as shown in Figure 2), also can take to recessed semicircular arc (as shown in Figure 3).
Claims (4)
