Abstract

The utility model relates to a domestic water heater using the technology of using heat-pipes to transfer heat. The utility model has the advantages of high safety and reliability, convenient operation, no room limitation and easy moving, being suitable for working with various heating sources such as electric, gas and honeycomb briquette stoves, kerosene stoves, etc. The water heater is composed of a tubular housing (2), a concave internal bladder (1), etc. The internal bladder and a heat pipe are synthesized. One end of the heat pipe absorbs heat at the heating source, and the other end extends into water for heat elimination to reach the aim of fast heating water. A cold water inlet pipe of the water heater is arranged on the lower part of the housing, and a hot water outlet pipe is arranged on the upper part of the housing. The water heater is provided with a thermometer to watch temperature and is provided with a safety valve to prevent the internal pressure of the contain from increasing and decreasing.

Description

Heat pipe type domestic water heater

The utility model relates to technical field of heat exchange, the pot-type boiler that specifically adopts hot pipe technique to make.

As everyone knows, pot-type boiler has two big classes in the market: electric heating type and combustion gas hot type (comprising piped gas and liquefied gas).This two classes pot-type boiler all must be with special thermal source, i.e. electricity consumption can not use coal gas; With coal gas can not electricity consumption.With regard to combustion heater, must be divided into piped gas and liquefied gas, both can not be general.There are electric shock, gas poisoning to take place during this two classes water heater, jeopardize user's life.This two classes water heater volume is bigger in addition, and the formality complexity is installed, and makes troubles to use.

The purpose of this utility model is to provide a kind of simple in structure, safe, reliable for people, operate, install simple and easy, not limited by the room, be convenient to move, and can be applicable to the upward pot-type boiler of work of multiple thermal source (as: thermals source such as electricity, combustion gas, briquette stove, kerosene stove, biogas stove).Be characterized in simple in structure, movement-less part, volume is little, thermal efficiency height and good reliability, and can realize that heating-up temperature, time controls long service life automatically.

Purpose is achieved in that in a container heat pipe is housed, and heat pipe one end links to each other with thermal source, and the other end stretches in the heating container that fills water.The working medium evaporation of back in the heat pipe of being heated of the heat source side of heat pipe, steam is transported and condensation, then by capillarity, makes the condensate liquid in the pipe turn back to evaporator section from condensation segment, and heat energy is delivered to another part from the part of heat pipe, thus the water in the heating container.

Fig. 1 is a heat pipe type pot-type boiler structure chart.

Fig. 2 is the water heater working schematic diagram.

Below in conjunction with accompanying drawing the utility model example is explained.

Fig. 1 shows the structure of this water heater.(2) be shell, inner bag (1) is matrix, and heat pipe (3) runs through about the inner bag, and its upper end is in the water heater, and its lower end is in the thermal source, and heat pipe is divided into some heating regions with water heater inside.Cold water (running water) enters from water heater bottom water inlet pipe joint (9), and heating back hot water flows out from hot-water line water outlet pipe joint (7).This water heater top is equipped with the thermometer (6) of measuring water temperature and is to prevent the safety valve (5) that the hypertonia pressure release is used.For ease of moving, carry climbing (4) is housed, (8).

Fig. 2 shows the fundamental diagram of this water heater.Arrow is represented the heat direction of transfer.After hot-water line inner bag (1) was located to be heated, because the heat-transfer character of heat pipe (3) itself, its lower end was delivered to the heat pipe upper end rapidly with heat, and by the water of heat pipe shell around external diffusion passes to.Because heat pipe is very near isothermal, and thermal capacity is big, just make the water at container internal upper part, bottom, outside and center all be subjected to the high temperature heating.Heat energy is given the lower end of inner bag (1) and heat pipe (3) by radiation, heat conduction, and passes through the heat conduction of inner bag (1), the transmission of inside heat pipe working medium, and the free convection campaign of the interior water of container, and water temperature is raise rapidly, reaches the purpose that adds hot water.Hot water flows out from top, and cold water will constantly flow into automatically from the bottom and replenish.Because this water-heater heat-exchanging efficient height, just can guarantee that hot water supplies continuously.Hot water in the water heater communicates with ambient atmosphere by pipe, so do not produce pressure in the operating position lower water-heater.When hot water stops to flow out, heat time heating time is long, when producing pressure in the water heater, can start relieving pressure by safety valve, guarantee water heater safety's reliably working.

This water heater has following advantage:

1, simple in structure, movement-less part, installation, convenient in carrying.

2, can on multiple thermal source, use, as: electric heater, coal gas, liquefied gas, biogas, briquette stove, kerosene stove etc.

3, firing rate is fast, and the temperature height can satisfy the needs of continuous water.

4, can realize controlling automatically water temperature, heat time heating time.

5, safe and reliable, the life-span is long.

This water heater also can adopt the form that is connected with the running water hard tube except that Fig. 1 structure; The connection of inside and outside courage can be adopted forms such as flange connection or punching press connection.

The not only alternative general instant shower heater of the utility model water heater also can be used as family, the catering trade, lodging industry, field work life " miniature boiler " with hot water.

Claims

1, a kind of pot-type boiler with heat transfer technology of heat pipe, it is characterized in that by shell (2) inner bag (1), heat pipe (3), cooling water inlet joint (9), the hot water outlet joint, (7) thermometer (6), safety valve (5) is formed, the inner bag of water heater is matrix, and synthetic with heat pipe (3), heat pipe one end is in the thermal source, and the other end stretches into the interior heat pipe of water heater water heater inside is divided into some heating regions.

2, water heater according to claim 1 is characterized in that: the safety valve (5) that the thermometer (6) of observing water temperature is equipped with the water heater internal pressure of releasing is housed.
