Abstract

The utility model relates to a helioplant, which comprises a plurality of light gathering grooves on the surface of a parabolic cylinder and a plurality of heat absorbing pipes arranged in a frame in parallel. The edges of the light gathering grooves are fixed on the support columns of the light gathering grooves by screws; a plurality of heat absorbing pipes are placed on the focusing lines of the reflecting curved surfaces of the light gathering grooves; one end of every heat absorbing pipe is communicated with a water inlet pipe, and the other end of every heat absorbing pipe is communicated with a water outlet pipe; both ends of the water inlet pipe and the water outlet pipe are placed on the edges at both sides of the frame. A cover board of the frame is made from glass with preferred light-admitting quality, and the bottom of the frame is padded with a heat insulating material layer. A plurality of the utility models can be used by connecting in parallel and be placed on the roof or the ground flatly in the direction from south to north.

Description

High efficiency solar energy water heater

Efficient solar water heater is a kind of helioplant, the solar water heater that particularly a kind of a plurality of parabolic cylinder condenser grooves and a plurality of endothermic tube are formed.

Existing focus type solar energy hydrophone such as application number are that 92211735.7 " solar energy focalizer " and application number are that 86205939 " parabolic cylinder solar hot-water kitchen range " all is to utilize the parabolic cylinder reflecting surface to focus on, endothermic tube places on the focal line of parabolic cylinder reflecting surface, but all be single condenser groove, single endothermic tube, be fixed in ground with support, the hot water amount is little, and is fixing unstable, and be to wear about 30-45 ° inclination angle with ground, the utilization rate on sunlight and roof is low.And for example application number is 93202138 " a kind of Salar light-gathering groove gatherer ", its available a plurality of condenser groove combinations, but condenser groove is to give the system face with cement concrete, can not guarantee paraboloidal accuracy, and heavy, be difficult for transporting and installing.

The purpose of this utility model is the solar water heater that a kind of temperature height of design, big, light, the easy transportation of hot water amount are easily installed.

The utility model is made of parabolic cylinder condenser groove, endothermic tube, condenser groove support column, hold-down screw, framework, cover plate, outlet pipe, water inlet pipe and heat-insulating material.Its reflecting curved surface of parabolic cylinder condenser groove is followed following parabolic standard equation y ²=2px makes.A plurality of condenser grooves are arranged in parallel within the framework, and the edge of condenser groove is screwed on the condenser groove support column.A plurality of endothermic tubes are placed in respectively on the focal line of condenser groove reflecting curved surface, and an end of each endothermic tube is communicated with water inlet pipe, and the other end is communicated with outlet pipe, also are that endothermic tube and water inlet pipe, outlet pipe are welded into an integral body.The two ends of water inlet pipe and the two ends of outlet pipe rest respectively on the frame on limit, framework two ends.The cover plate of framework is with the good glass of light transmission, framework bottom surface pad last layer heat-insulating material.North and South direction directly kept flat roof or the good ground of daylighting when the utility model was installed.A plurality of water heaters can in parallelly use, and outlet pipe (4), water inlet pipe (5) are connected to each other respectively, can obtain bigger hot water.

The utility model has the advantages that has a plurality of parabolic cylinder condenser grooves and endothermic tube corresponding with it in a water heater, and lies against roof or ground, and the time that receives sunshine is long, so the hot water amount is big, simultaneously, a plurality of water heaters can in parallelly use, and more households use for high-rise building.This real new structure is simple, can industrial production, can punch forming as condenser groove, and cost is low, and is in light weight, is easy to transportation and installs.

Below in conjunction with description of drawings embodiment of the present utility model

Embodiment of the present utility model is the water heater of three condenser grooves, three endothermic tubes.

Fig. 1 is the structural representation of the utility model embodiment.

Numbering 1 is the parabolic cylinder condenser groove among the figure, and 2 is endothermic tube, and 3 is glass cover-plate, and 4 is outlet pipe, and 5 is water inlet pipe, and 6 is the condenser groove support column, and 7 is the edge of condenser groove, and 8 is framework, and 9 is heat-insulating material, and 10 is screw.

The utility model is by three parabolic cylinder condenser grooves (1), three endothermic tubes (2), water inlet pipe (5), outlet pipe (4), framework (8), glass cover-plate (3), condenser groove support column (6), heat-insulating material (9) and screw (10) constitute the metal parabolic cylinder condenser groove that (as shown in Figure 1) three is stamped to form, its reflecting surface is handled through polishing or chromium plating, length is slightly less than framework (8) length, be placed in parallel in the framework (8), the two edges (7) of a middle condenser groove, overlapping with the close edge (7) of two condenser grooves in both sides (1) respectively, be fixed on screw (10) two on the support column (6) of condenser groove, the two at another edge (7) of the condenser groove on both sides (1) uses screw (10) to be fixed on the condenser groove support column (6) respectively.With corresponding three endothermic tubes of parabolic cylinder condenser groove (1) can be with general water pipe or aluminum pipe, on the parallel focal line that is seated in corresponding parabolic cylinder condenser groove (1) reflecting curved surface, its two ends are communicated with water inlet pipe (5), outlet pipe (4) respectively and are welded into an integral body (as shown in Figure 1).Water inlet pipe (5) rests respectively on the frame of framework (8) with the two ends of outlet pipe (4).Tank bracket (8) is rectangle, and makes with aluminum alloy materials.Framework bottom surface galvanized sheet, bottom surface pad last layer foamed plastic is made heat-insulating material (9).During installation, the water heater North and South direction lies directly in roof or the good ground of daylighting.

Claims

1, a kind of efficient solar water heater, comprise the parabolic cylinder condenser groove, endothermic tube, water inlet pipe, outlet pipe and insulation material, it is characterized in that having a plurality of parabolic cylinder condenser grooves (1) to be parallel in the framework (8), the edge of condenser groove (1) is fixed on the condenser groove support column (6) with screw (10), on the parallel focal line that is placed in condenser groove (1) reflecting curved surface with the corresponding a plurality of endothermic tubes of parabolic cylinder condenser groove (1) (2), one end of each endothermic tube (2) is communicated with water inlet pipe (5), the other end is communicated with outlet pipe (4), and the limit that the two ends of water inlet pipe (5) and outlet pipe (4) rest framework (8) both sides respectively cashier's office in a shop.
