Abstract
A rough surface hot-pressing device for the shielding glass tube of an evacuated collector tube is characterized by comprising a set of two hot-press forming dies for pressing the shielding glass tube together from the inner wall and the outer wall of the shielding glass tube, wherein at least one of the two hot-press forming dies is provided with a rough surface. The utility model has the benefits as follows: shielding glass tube hot-pressing equipment is used for forming the rough surface on the inner wall or the outer wall of the shielding glass tube, and then a diffuse reflection mirror surface can be manufactured on the rough surface; in virtue of the diffuse reflection of the mirror surface, the phenomenon that sunlight originally penetrating through the space between the shielding glass tube and an inner glass tube and reaching the smooth mirror surface on the inner wall of the shielding glass tube overflows from the other side of the shielding glass tube is changed; and most of the sunlight is enabled to fall on an absorbing film on the inner glass tube, so as to realize light gathering of the mirror surface of the glass shielding tube without using an eccentric inner glass tube or a built-in metal reflection board with serious gas escape.
Description
Technical field
The utility model relates to vacuum heat collection pipe cover glass tube hot pressing uneven surface pressure assembly.
Background technology
The mode of vacuum heat collection pipe heat energy output preferably adopts the heat pipe made from the inner glass tube one.Existing a kind of explosion-proof vacuum heat collector tube pipe for anti-fried, is reduced to the working medium full quantity below 0.5% from accounting for internal capacity 10～20%, makes inner two phase flow heat transfer not reach perfect condition far away.Existing a kind of eccentric vacuum heat collection pipe of inner glass tube that utilizes cover glass tube inwall minute surface reflector optically focused, it has, and the sunshine of reception scope is big, the thin area of dissipation of inner glass tube and heat sink little advantage, but the eccentric sealing-in difficulty of inner glass tube is higher.
Summary of the invention
The purpose of the utility model is that vacuum heat collection pipe cover glass tube hot pressing uneven surface pressure assembly will be provided.
The utility model solves technical scheme that its technical problem is taked: use secondary two heat pressing and molding molds of jointly cover glass tube being exerted pressure from the cover glass tube inner and outer wall, form a cover glass tube hot pressing uneven surface pressure assembly.In said one secondary two heat pressing and molding molds at least one contains uneven surface.
The beneficial effect of the utility model: utilize the cover glass tube hot-press equipment to form a uneven surface, just can make the diffuse-reflectance minute surface at this uneven surface at cover glass tube inwall or outer wall.Utilize the diffuse-reflectance of this minute surface, make and pass the sunlight that arrives cover glass tube inner wall smooth minute surface between cover glass tube and the inner glass tube originally, the phenomenon of overflowing from the cover glass tube opposite side because of total reflection changes; And these sunlight major parts are projected on the absorbing film of inner glass tube, realize cover glass tube minute surface light harvesting and need not eccentric inner glass tube or need not the serious metal reflective plate of built-in venting.Minute surface for making in the pickling of cover glass tube outer wall frosting need be provided with a resist.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is a cover glass tube hot pressing uneven surface device side TV structure synoptic diagram.
Fig. 2 is that a cover glass tube hot pressing uneven surface device is faced structural representation.
1. cover glass tubes among the figure; 2. patrix; 3. counterdie.
Embodiment
Fig. 1 and Fig. 2 provide an embodiment of the utility model jointly.
Among Fig. 1 and Fig. 2, use the heat pressing and molding mold patrix 2 and the counterdie 3 that contain uneven surface, stretch into cover glass tube 1, form a cover glass tube hot pressing uneven surface pressure assembly.When hot-forming, the cover glass tube that is heated to softening temperature 1 is placed on the press machine lower die 3, stretch into cover glass tube 1 with patrix 2.One secondary upper and lower two heat pressing and molding molds 2,3 are exerted pressure to cover glass tube 1 jointly from cover glass tube 1 inner and outer wall and are made it form uneven surface.Hot-forming uneven surface process velocity is fast, can obtain precision and ideal optically focused is surperficial.When uneven surface surpasses 50 degree inscribed angle, but can use 2 pairs of cover glass tubes of rolling upper mould 1 to carry out roll extrusion.
Fig. 1 and Fig. 2 embodiment cover glass tube hot pressing uneven surface device can combine with flattening technology.Be specially: the cover glass tube 1 that will be heated to softening temperature earlier is pressed into oblate making it and coincide with counterdie, and and then hot repressing forms uneven surface.
Claims (1)
1. vacuum heat collection pipe cover glass tube hot pressing uneven surface pressure assembly is characterized in that containing secondary two heat pressing and molding molds of jointly cover glass tube being exerted pressure from the cover glass tube inner and outer wall; In said one secondary two heat pressing and molding molds at least one contains uneven surface.
