As preferably, described sealing device is a sealing-plug.Like this, use sealing-plug that can be simple seals the two ends of cloche.
As preferably, described in pipe be metal tube.Like this, load performance is better.
As preferably, also comprise the heat-conducting plate of the upper surface of being located at described thermal insulation layer, the upper surface of described heat-conducting plate contacts with described metal tube.Like this, heat-conducting effect is better, is more conducive to the heating of metal tube.
Same conduct is preferred, also comprises reflector layer, and described reflector layer is located at the upper surface of described thermal insulation layer.Like this, it is more abundant to absorb sunlight, is beneficial to the heating of the bottom of metal tube more.
As preferably, removable being connected on the described mount pad of described cloche be meant, described cloche by clamp connection on described mount pad.Like this, can play good connection effect, be convenient to the installation and removal of cloche again.
As further preferred, the clip of described clip for making by elastomeric material.Like this, be difficult for cloche is caused damage.
As preferably, the cross section of described dual-layer vacuum glass cover roughly takes the shape of the letter U.
Same as preferred, the opening part in the cross section of described dual-layer vacuum glass cover is bell mouth shape.Like this, packing and transportation are convenient in the placement that can be superimposed together of a plurality of cloches more.
