Description
Technical field
The utility model belongs to the heat exchange element technical field, relates to a kind of plate solar collector.
Background technology
Solar water heater makes full use of solar energy resources, and solar energy is converted into heat energy, and water is heated to high-temperature from low temperature, uses to satisfy the hot water of people in life, production.Solar water heater is made up of thermal-collecting tube, storage tank and related accessories, solar energy is converted to heat energy mainly rely on the thermal-arrest plate.The thermal-arrest plate is subjected to solar radiation surface temperature height, and thermal-arrest backboard sunny side temperature is low, and the water in the thermal-arrest plate just produces temperature difference reaction, and the principle of utilizing hot water come-up cold water to sink makes the water generates microcirculation and reaches the purpose that adds hot water.
Traditional solar water heater is open type and is installed on the roof, perhaps is suspended on balcony or the exterior wall, in case run into Changes in weather, tends to make water heater to be subjected to beyond thought damage.Tend to carry secretly a large amount of hails when rainy, when hail surpasses constant weight, will smash the thermal-collecting tube on the thermal-arrest plate, so just influenced the effect of water heater, if broken many of thermal-collecting tube, water heater does not just have the heat energy conversion effect, has reduced the service life of water heater.And water heater is installed in the roof, and people are difficult to find that in time thermal-collecting tube is broken, therefore in use, will bring many worries and unnecessary trouble to the user.
For this reason, people have proposed various solutions through long-term exploration, and some has also applied for patent.For example; Chinese patent discloses a kind of glass tube with vacuum solar heat-collection plate printing opacity protective device [Granted publication number be: CN 2514272Y]; it is connected institute by the solar heat-collection plate of the plated film glass tube with vacuum that belt supporting frame, hot water flow tube are installed and forms with protection mechanism; and protection mechanism is made of connector on the solar energy heating plate framework and dismantled and assembled the linking into an integrated entity of light permeable protection; as long as unclamp or tighten screw; just light permeable protection be can open, maintenance and transposing part are convenient to.
Though above-mentioned protective device can play the purpose that prevents that thermal-collecting tube is broken, when sunlight passes this protective cover,, make the thermal-arrest plate can not fully absorb solar energy because the effect of protective cover weakens the Yanguan Pass intensity on the direct arrival thermal-arrest plate.If use this protective cover, do not have the purpose of utilizing solar energy that water is heated at the insufficient weather of sunlight at all.
Summary of the invention
The purpose of this utility model is at the above-mentioned problems in the prior art, provides a kind of collecting efficiency high plate solar collector.
The purpose of this utility model can realize by following technical proposal: a kind of plate solar collector, comprise a base, this base has a cavity along horizontal spreading, the surface of described cavity is provided with a thermal insulation layer, place, bottom surface at the above cavity of thermal insulation layer is provided with some heat-exchange tubes in a tubular form, it is characterized in that the open-mouth of described base cavity is coated with one deck transparent glass, the surface of described transparent glass has some convex bodys that are used for optically focused.
Make heat-exchange tube be positioned at the cavity of sealing by transparent glass: i.e. the cavity that forms of cavity and transparent glass, avoid heat-exchange tube to be clashed into and damage.Certainly, because solar ray energy passes transparent glass, make that heat-exchange tube can operate as normal.
Owing to have the convex body of energy optically focused on the transparent glass, so just make heat-exchange tube be subjected to the irradiation of strong beam, heat-exchange tube just can obtain more heat.
In above-mentioned plate solar collector, the material of described thermal insulation layer is a foamed plastics.
In above-mentioned plate solar collector, described insulating layer material is the mineral wool goods.
The thermal insulation layer that foamed plastics and stimulative substance cotton products are made has good thermal insulation, makes that the temperature in the cavity can very fast loss.
In above-mentioned plate solar collector, described convex body laterally is circular-arc protrusion along transparent glass.
In above-mentioned plate solar collector, described convex body is to be some salient points that sphere protrudes.
In above-mentioned plate solar collector, described convex body laterally is tip-angled shape along transparent glass and protrudes.
In above-mentioned plate solar collector, the both sides of described transparent glass all have convex body.
The said structure of convex body makes it have good spotlight effect.
In above-mentioned plate solar collector, also have heat-conducting plate between described thermal insulation layer and the transparent glass, above-mentioned heat-exchange tube is connected on the heat-conducting plate.Convex body on the transparent glass can easily expose to strong beam on the heat-conducting plate, by heat-conducting plate heat is passed to the heat-exchange tube place again.Such structure has avoided strong beam possibly can't be radiated on the heat-exchange tube accurately.
In above-mentioned plate solar collector, described heat-exchange tube is a copper pipe.When having sufficient intensity, the heat-exchange tube that adopts this material to make also has good thermal conductivity.
In above-mentioned plate solar collector, described heat-conducting plate is made by the red copper material.The red copper material has good thermal conductivity, and the heat-conducting plate that adopts this material to make can transmit heat fast.
Compared with prior art, this plate solar collector can accumulate in strong beam at the heat-exchange tube place owing to have convex body on the transparent glass by convex body, makes heat-exchange tube obtain more heat, has increased its Heat-collecting effect.
Simultaneously, it just has convex body on transparent glass, and therefore, structure is also fairly simple, has the higher utility of ratio.
