Abstract
The utility model relates to the improvement technology of a pressure-bearing water tank of a solar water heater, and provides a natural circulating pressure-bearing water tank of a spiral coil heat exchanger. The water tank is provided with an outer container and an inner container which are horizontally arranged and are cylindrical; heat preservation materials are arranged between the inner container and the outer container; a left end cover and a right cover are arranged at two ends of the inner container and the outer container to form a box body; a cold water inlet and a hot water outlet are formed in the box body. The water tank is characterized in that the spiral coil heat exchanger is mounted inside the box body through a fixed bracket; a center axle line of the spiral coil heat exchanger is perpendicularly arranged, the thread pitch is 40-50 mm and is wound in waist shape or ellipse, and a waist-shaped or elliptic long shaft is arranged in the cylindrical inner container axis line direction; a circulating inlet and a circulating outlet of the spiral coil heat exchanger penetrate water tank end covers; the arrangement is that the circulating inlet is at the upper part and the circulating out let is at the lower part. The water tank overcomes the problems that a conventional pressure-bearing water tank should adopts a circulating pump to conduct circulating heat exchange, the commercial power is required, the energy consumption is existed, and freeze resistance is not existed, and is mainly used for a solar water heater system.
Description
Technical field
The utility model relates to the improvement technology of press-bearing water tank of solar energy water heater, especially a kind of spiral coil heat exchanger Natural Circulation press-bearing water tank.
Background technology
Along with the increase of modern society's energy-conserving and environment-protective consciousness, solar water heating system is used widely; Solar water heating system includes solar thermal collector, heat-exchanging water tank, and auxiliary electrical heater, pipeline, mounting bracket forms; The problem that existing solar water heating system heat-exchanging water tank exists is: in the solar water heater of Natural Circulation, heat-exchanging water tank can not adopt indirect cyclic process, with solar thermal collector, be connected and can only heat by the water direct circulation, whole water heater can not be freeze proof, although the splitting solar hot-water heating system can be freeze proof, but must use circulating pump external force, carry out temperature difference controlled circulation by differential temperature controller, need to use civil power.The direct circulation solar water heater can only be used in south, can not be antifreeze, and this has just proposed new requirement to the improvement of close-coupled solar water heater.
Summary of the invention
The defects such as the purpose of this utility model is exactly that the press-bearing water tank that will solve existing solar water heater system must adopt circulating pump to carry out cycle heat exchange, needs civil power, and energy consumption is arranged, not freeze proof, provide a kind of spiral coil heat exchanger Natural Circulation press-bearing water tank.
Concrete scheme of the present utility model is: improve for existing press-bearing water tank, it has the outer courage of horizontally-arranged tubular and inner bag, between inner-outer tube, be provided with insulation material, the inner-outer tube two ends are provided with the left and right end cap and form casing, on casing, be provided with cooling water inlet and hot water outlet, it is characterized in that: by a fixed mount, spiral coil heat exchanger is installed in casing, this spiral coil heat exchanger axis is arranged vertically, its pitch is 40-50mm, and be kidney-shaped or oval coiling, kidney-shaped or oval-shaped long axis tubular inner bag axis direction are arranged, the circulation of spiral coil heat exchanger is imported and exported and is passed water tank end cap, and the circulation import of spiral coil heat exchanger is upper, outlet is in lower layout.
Fixed mount described in the utility model includes and is placed in four struts that inner bag is arranged symmetrically with up and down in twos, the same side between two struts, the vertically arranged fixed card in left and right is housed up and down, totally four fixed cards, each fixed card includes interior card article and outer card article, interior card article or outside be provided with the groove that corresponding every one spiral coil passes through between card article or inside and outside card article, inside and outside card article fills and is integrated by connector, and spiral coil heat exchanger is positioned fixing.
Electrical auxiliary heater is housed in the utility model in casing, the power connection end of electrical auxiliary heater stretches out a side end cap; And the casing top offers the temperature, pressure relief valve connection.
Operation principle of the present utility model is: this press-bearing water tank provides thermal source by the energy of plate solar collector or solar energy glass vacuum pipe heat collector or other form, when this press-bearing water tank was installed, minimum position was higher than the high-order bit of heat collector, and heat exchanger and heat collector in casing are connected to form a closed loop.At heat collector, absorb solar energy (or other energy), after the medium temperature in heat collector raises, due to thermosiphon principle, thereby circulate and heat the domestic water in this water tank with the spiral coil heat exchanger in casing.
The utility model has adopted rational spiral coil and kidney-shaped or oval coiling, and adopt fixedly spiral coil heat exchanger of fixed mount, thereby guaranteed natural circulation heating of the present utility model, working stability is reliable, and the utility model is reasonable in design, compact conformation, without power supply, save the energy, be in all the time the thermal cycle state, good freezing protection effect.
