Modular solar water heater without water tank

Abstract

The invention relates to a modular solar water heater without a water tank, which is formed by assembling a plurality of heat collecting modules which mainly comprise a glass vacuum pipe, a sealing pipe plug, a water inlet pipe, a water outlet pipe and an electric heating pipe. The pipe orifice of the glass vacuum pipe is sealed by the sealing pipe plug; the sealing pipe plug is inserted with the water inlet pipe, the water outlet pipe and the electric heating pipe; the water inlet pipe and the water outlet pipe of the heat collecting modules are connected with a plug through an elbow respectively; both the outer wall of the pipe orifice and the outer wall of the tail of the glass vacuum pipe of each heat collecting module are bonded with a supporting plate; both the upper supporting surface and the lower supporting surface of the supporting plate are provided with two positioning holes; the supporting plates of the adjacent heat collecting modules are connected in series to form a whole through a cascading rod passing through the positioning holes; and water and electricity of the plurality of heat collecting modules are synchronously connected through splicing pipes and electric connectors. The integral connection is convenient and fast, stable and firm; the safety performance is high, and the service life is long; the transportation, assembly and maintenance are convenient; the cost is greatly reduced; and the practicability is strong.

Description

Technical field [0001] The invention relates to a solar water heater, in particular to a modular assembled solar water heater without a water tank. Background technique [0002] Traditional solar water heaters without water tanks use large-diameter glass vacuum tubes to form a heat collector that collects and stores heat. The heat collection effect is better. Compared with traditional water heaters with water tanks, it has a relatively small volume and can be combined with buildings in a variety of ways. Supporting installation. [0003] At present, the common solar water heaters without water tank are: the glass vacuum tube is connected in series by a pipe to form a heat collector. For example, the all-weather pressure-bearing solar water heater without water tank disclosed in the patent number 200510095034.4 adopts a "U" or "L" tube The glass vacuum tubes are connected in series to form an integral structure collector, which is inconvenient to transport and install, or to assem...
