Description

Heat pipe hot pump formula water heater

Affiliated technical field

The utility model relates to a kind of water heater, particularly utilizes the water heater of heat pipe hot pump heating.

Technical background

The water heater that existing bathing is used is divided three classes substantially: gas heater, electric heater and solar water heater.Gas heater power consumption is high and insufficient environment is had pollution because of burning; Electric heater is for keeping the water temperature of storage tank, and electrothermal tube is switched on power consumption greatly for a long time, and its body long period of soaking is adhered to the dirt layer easily in the water outer surface, and the electrothermal tube thermal efficiency after the fouling reduces, and body is explosion easily also; Solar water heater is subjected to the restriction of storage tank volume, can't obtain hot water endlessly, but also has increased the heat of electric auxiliary heating device with compensation solar energy because of the influence that is subjected to temperature in season.All there be high inconvenience and the unsafe factor of using of power consumption in gas heater, electric heater and solar water heater.

Summary of the invention

At the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of water heater, and this water heater can provide hot water continuously, power consumption is low, heating is rapid and safe and convenient to use.

Main technical schemes of the present utility model is: this kind heat pipe hot pump formula water heater, comprise water inlet pipe, outlet pipe and heater, it is characterized in that: described heater is to be connected in series the closed circulatory system that forms successively through connecting pipe by parts such as evaporimeter, gas-liquid separator, compressor, circulation pipe, plate type heat exchanger and heating power expansion valves; Injected an amount of liquid refrigerant in the described circulatory system.

When environment temperature more than 5 ℃, cold-producing medium absorbs heat in the pipe-line system of evaporimeter, and expanding seethes with excitement vaporizes, compressed machine sucks by gas after the gas-liquid separator isolated by filtration and compression and improves its pressure and temperature, promote flow of refrigerant and create pressure differential, the mechanical energy of compressor converts heat energy to and discharges superheated steam, be transported to plate type heat exchanger through circulation pipe, make the bathing hydrothermal exchange that flows in high-temperature steam fluid and the plate type heat exchanger chamber, adjust flow of refrigerant pressure by heating power expansion valve after the high-temperature steam heat release condensation and return in the evaporimeter, continue next circulation.

As further improvement, circulation pipe is built in the electrical heating heat pipe collector of band outer liner tube, is provided with the electrothermal tube of a band internal lining pipe that can join with external power source at the inner space of circulation pipe, is filled with a certain amount of heat-conducting medium between the inside and outside bushing pipe.

When environment temperature below 5 ℃ the time, evaporimeter can't absorb superheat, the heat of compressed machine compressing and converting also can't with the bathing hydrothermal exchange, the power supply of connecting electrothermal tube this moment is the electrothermal tube heating, makes be heated running water heat exchange in back output superheated steam and the plate type heat exchanger of the circulation pipe that is built in the electrical heating heat pipe collector.

The inside of described plate type heat exchanger is divided into double-layer cavity, and outlet pipe, water inlet pipe are connected respectively with the upper/lower terminal in a chamber of plate type heat exchanger respectively, and the upper end in another chamber of plate type heat exchanger is communicated with circulation pipe, and its lower end is communicated with heating power expansion valve.

The beneficial effects of the utility model are: because the power consumption of this kind heat pump heat pipe water heater is low, promptly hydro-thermal can provide hot water continuously and can change with ambient air temperature and adjust power consumption power.Its volume is little, and is simple in structure, is fit to outdoor placement, saves user's careat.Safe and reliable.
