Description

Non-water tank solar water heater

Technical field

The utility model belongs to the solar water heater field, a kind of non-water tank solar water heater of more specifically saying so.

Background technology

The equipment of heat hot water at present commonly used has: boiler, fuel-oil water heater, gas heater, electric heater and solar water heater etc., wherein minimum with the solar water heater operating cost, and the trend of becoming increasingly prosperous arranged, but have several aspects to influence the use of solar water heater at present: the one, the price height, the 2nd, floor space is big, the 3rd, can inhabitation determining positions user install solar water heater, the 4th, existing solar water heater water tank is a bearing device, be necessary for cylindrical, can not change with fabric structure, influence attractive in appearance.

The utility model content

The purpose of this utility model is to provide a kind of non-water tank solar water heater, and it directly utilizes solar radiation to add hot water, uses for life, production.The utility model improves solar water heater from attractive in appearance, economical, three aspects of use at present present situation, and it has removed cylindrical press-bearing water tank, so that its shape can design and arrange with building requirements.Water heater pressure-bearing of the present utility model is born by U type pipe, makes the structure of solar water heater become ground simply.

Non-water tank solar water heater of the present utility model comprises water heater and support, and water heater comprises hot water outlet pipe, collector incubator, cold water inlet, insulation material, vacuum tube, heat exchanger and phase change heat storage material.In the described collector incubator insulation material, hot water outlet pipe and cold water inlet are arranged; Described heat exchanger is a U type pipe, and its water inlet is connected with cold water inlet, and delivery port is connected with the hot water outlet pipe; Heat exchanger and phase change heat storage material are loaded together in the vacuum tube cavity, and the vacuum tube mouth of pipe is inserted in the collector incubator; Whole water heater is by stent support, and vacuum tube pipe tail is enclosed within the support set on the support, and vacuum tube quantity can be decided as required.

Can be filled with flexible member again in the described vacuum tube cavity, to prevent that the material of flexible member can be owing to the phase change heat storage material volumetric expansion makes the vacuum tube explosion: various yielding materials such as rubber plastic pipe, thin-walled aluminiums.

The utility model has been compared following advantage with traditional solar water heater:

1. the utility model has replaced the water tank accumulation of heat with the phase change heat storage material accumulation of heat, saves the space, and is simple in structure;

2. the phase change heat storage material of equal volume is more than the water heat-retaining capacity of equal volume, and efficient is higher;

3. the utility model prevents to have improved the safety coefficient of water heater owing to the phase change heat storage material volumetric expansion makes the vacuum tube explosion with the frame mode of pre-buried flexible member, has prolonged service life;

4. the utility model more compact structure, good looking appearance reduces cost, and is economical and practical;

5. the utility model can adopt corresponding phase change heat storage material to obtain suitable hot water temperature according to different use occasions.

The specific embodiment

In order to understand the utility model better, below the utility model is done to describe further.

As depicted in figs. 1 and 2, non-water tank solar water heater of the present utility model comprises water heater and support 10, and water heater comprises hot water outlet pipe 1, collector incubator 2, cold water inlet 3, insulation material 4, vacuum tube 5, heat exchanger 6, phase change heat storage material 7 and flexible member 8.Insulation material 4, hot water outlet pipe 1 and cold water inlet 3 are arranged in the collector incubator 2; Described heat exchanger 6 is a Φ 5-Φ 11mm U type pipe, and its water inlet is connected with cold water inlet, and delivery port is connected with hot water outlet pipe 1; Heat exchanger 6, phase change heat storage material 7 and flexible member 8 are loaded together in vacuum tube 5 cavitys, and vacuum tube 5 mouths of pipe are inserted in the collector incubator 2.Whole water heater is supported by support 10, and vacuum tube 5 pipe tails are enclosed within the support set 9 on the support 10.

Because volume can expand behind phase change heat storage material 7 phase-transition heat-storages, therefore pre-buried flexible member 8 can prevent vacuum tube 5 explosions in vacuum tube 5, and the material of flexible member 8 can be: various yielding materials such as rubber plastic pipe, thin-walled aluminium.

The utility model method of operation is: during accumulation of heat, vacuum tube 5 absorbs solar radiant energy and at first heats phase change heat storage material 7, phase change heat storage material 7 phase-transition heat-storage in heating process, 4 insulation effects of insulation material in the collector incubator 2; When using hot water, cold water enters heat exchanger 6 and phase change heat storage material 7 heat exchange by cold water inlet 3, and temperature of cold water rises becomes hot water after the heat exchange, and passes out to watering equipment by hot water outlet pipe 1, flexible member 8 plays the effect of buffering phase change heat storage material 7 distortion, can prevent vacuum tube 5 explosions.

The utility model directly utilizes solar radiation to add hot water, replace the water tank accumulation of heat with phase change heat storage material, not only saved the space, and reduced cost, make and the utlity model has simple in structure, good looking appearance, advantage such as economical and practical, can adopt corresponding phase change heat storage material to obtain suitable hot water temperature according to different use occasions, can be widely used in the daily productive life.
