Abstract
The utility model discloses a heat collecting pipe for a solar water heater, which comprises a vacuum pipe with a heat conducting rod arranged therein The heat collecting pipe is simple in structure and convenient for use, the heat conducting rod is utilized for heating water, the problem that the heat collection rate drops due to the formation of water scale in the vacuum pipe is solved, and the service life of the heat collecting pipe is prolonged.
Description
Technical field
The utility model relates to the solar water heater field, specifically is a kind of thermal-collecting tube that is used for solar water heater.
Background technology
The existing thermal-collecting tube that is used for solar water heater is selected vacuum tube for use, collect the heat of solar energy by vacuum tube, then heat is delivered to water in the vacuum tube by the vacuum tube wall, water heat absorption back temperature in the vacuum tube raises, proportion reduces and rises, form a power that makes progress, constitute a thermal siphon system, along with hot water constantly on move and be stored in storage tank top, passing through down simultaneously, circulation pipe constantly replenishes the lower water of temperature, so move in circles, final whole box water all is increased to certain temperature.But this use principle has caused being easy to produce incrustation scale in the vacuum tube, has reduced the thermal-arrest rate and the service life of thermal-collecting tube.
The utility model content
Technical scheme to be solved in the utility model provides a kind of thermal-collecting tube that is used for solar water heater, solves traditional thermal-collecting tube and is easy to generate incrustation scale, the problem that the life-span is short.
The technical solution of the utility model is:
A kind of thermal-collecting tube that is used for solar water heater comprises vacuum tube, is provided with heat conductive rod in the described vacuum tube, and stretch out outside the vacuum tube on the top of heat conductive rod.
Be provided with one group of cushion block between described vacuum tube and the heat conductive rod.
Described vacuum tube top is connected with end cap, is axially arranged with perforate on the end cap, and stretch out outside the vacuum tube by perforate on heat conductive rod top.
Between the bottom of described vacuum tube and the bottom of heat conductive rod, be provided with cushion block between the sidewall of vacuum tube and the sidewall of heat conductive rod.
Described end cap inner ring is provided with gasket seal and cooperates with the vacuum tube end sealing; The outer ring of described end cap is provided with installing hole.
Described vacuum tube top outer wall is provided with screw thread, and described end cap inwall is provided with the screw thread with vacuum tube push pipe threaded engagement.
Heat conductive rod described in the utility model be copper or silver and cooling fluid make.
Operation principle of the present utility model: do not leak water in the described vacuum tube, give heat conductive rod with thermal energy conduction behind the vacuum tube thermal-arrest, heat conductive rod stretches in the storage tank inner bag, and the heat energy of heat conductive rod conducts to the water in the storage tank inner bag again water temperature is risen.
The utility model is not because of leaking water in the vacuum rods, solved the problem that easily produces incrustation scale in the conventional thermal-collecting tube, increased the service life of vacuum tube, even and vacuum tube break, do not influence the normal use of solar water heater yet.
The utility model is simple in structure, and is easy to use, utilizes heat conductive rod that water is heated, and solved to produce the problem that incrustation scale causes the thermal-arrest rate to descend in the vacuum tube, increased the service life of thermal-collecting tube.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the mounting structure schematic diagram of the utility model embodiment.
The specific embodiment
See Fig. 1, a kind of thermal-collecting tube that is used for solar water heater, comprise vacuum tube 1, be provided with heat conductive rod 2 in the vacuum tube 1, the vacuum tube top is connected with end cap 5, be fixed with one group of cushion block 3 between vacuum tube 1 and the heat conductive rod 2, the top outer wall of vacuum tube 1 is provided with screw thread 4, end cap 5 inwalls are provided with the screw thread of vacuum tube 1 push pipe threaded engagement vacuum tube 1 top are connected with end cap 5, end cap 5 inner rings are provided with gasket seal 6 and cooperate with vacuum tube 1 end sealing, be axially arranged with perforate 7 on the end cap 5, stretch out outside the vacuum tube 1 by perforate 7 on heat conductive rod 2 tops, and the outer ring of end cap 5 is provided with installing hole 8.
See Fig. 2, when the utility model was installed, the top of heat conductive rod 2 was stretched in storage tank 9 inner bags, and vacuum rods 1 is fixedly installed on the storage tank 9 by installing hole 8, nut and steel plate 10 cooperations, and the top is positioned at outside storage tank 9 inner bags.
Operation principle of the present utility model is to give heat conductive rod 2 with thermal energy conduction after utilizing vacuum tube 1 thermal-arrest, heat conductive rod 2 stretches in storage tank 9 inner bags, the heat energy of heat conductive rod 2 conducts to the water in storage tank 9 inner bags again water temperature is risen, guaranteed not leak water in the vacuum tube 1, not having incrustation scale produces, and vacuum tube 1 breaks, and also can not influence the normal use of solar water heater.
