Description
Technical field
The present invention relates to the gravity heat pipe heat exchanger in a kind of air-conditioning.
Background technology
Heat pipe is a kind of heat transfer element with high thermal conductivity, and it is by the evaporation of the working medium in Totally enclosed vacuum shell
Transmit heat with condensing, with high thermal conductivity, good isothermal, cold and hot both sides heat transfer area can arbitrarily change,
Can the series of advantages such as remotely transferring, temperature controllable.
Heat pipe is the high-performance heat transfer components that heat transfer is realized by the phase transformation of therein hydraulic fluid, and it can be by big calorimetric
Amount by the sectional area of its very little transmit over long distances and without additionaling power.Heat pipe is skillfully constructed with it, and the transmission temperature difference is small suitable
With wide temperature range, numerous good characteristics such as heat flow density in adjustable keyholed back plate have shown in terms of energy regenerating and UTILIZATION OF VESIDUAL HEAT IN
Go out the effect of its uniqueness.Heat exchange of heat pipe belongs to the non-touching surface-type heat exchange of cold fluid and hot fluid, and the occupation of land that it has is small, nothing turns
The good characteristic such as dynamic component, safe and reliable to operation, heat exchange efficiency be high is engineering from creating convenience.
Heat exchanger with heat pipe as heat transfer element has heat transfer efficiency high, compact conformation, fluid resistance damage is small, be conducive to control
The advantages of dew point corrosion.It is widely used to the industries such as metallurgy, chemical industry, oil refining, boiler, ceramics, traffic, light textile, machinery at present
In, as the energy-saving equipment of heat energy utilization in Waste Heat Recovery and technical process, achieve significant economic benefit.
Hot-pipe type heat-exchanger is the air-to-air energy recovery equipment commonly used in current air-conditioning system, and hot-pipe type heat-exchanger is main
It is made up of several heat pipes.Gravity assisted heat pipe heat exchanger two parts of thermal current and cold airflow by being made up of respectively.Heat pipe
It is made up of the airtight vacuum metal tube of inside filling refrigerant, once heat pipe one end (condensation end evaporation ends) are heated, in external heat
In the presence of, vaporization in the liquid short time in pipe, and the other end of heat pipe is flowed in the presence of differential pressure, then these gases pair
The external world releases heat and is condensed into liquid, and then these liquid return to heat pipe original end (condensation end) by Action of Gravity Field again, and
It is heated again vaporization, such course of work is constantly circulated, and heat is just endlessly delivered to that end from this end of heat pipe.
Gravity heat pipe heat exchanger in the air-conditioning for using at present is unidirectional heat transfer, because the position up and down of gravity assisted heat pipe
Respectively condenser and evaporator, the heat absorption of upside heat release downside, therefore hot blast is always flowed through in the downside of heat exchanger, upside is always flowed
Cross cold wind.Winter room air is hot blast, and outdoor air is cold wind, on the contrary summer；Therefore for the summer in gravity heat pipe heat exchanger winter
The cold-hot wind direction in season is different.
Winter fresh air is exchanged heat in upper air draft under, downside air draft heat release, the heat absorption of upside fresh air, fresh air and air exhaust heat exchange
Heat up；Summer fresh air is exchanged heat in lower air draft upper, upside air draft heat release, and upside fresh air heat absorption, fresh air drops with air exhaust heat exchange
Temperature.
The shortcoming of this heat exchange of heat pipe is that Summer and winter can not freely switch, for gravity type heat pipe, condensation segment
Installation site necessarily be greater than evaporator section, thus it is applied to occasion of the cold wind in upper, hot blast under；If complete for air-conditioning system
Year exhaust air energy recovery, then winter carry out needing to change the position into, exhaust outlet relative to heat pipe when fresh air preheating is processed.
The content of the invention
The present invention is to solve the above problems, there is provided the gravity heat pipe heat exchanger that can switch in the summer in winter in a kind of air-conditioning and its switching
Method, can adapt to the ventilation heat exchange requirement of summer in winter Various Seasonal.
To achieve the above object, the technical solution adopted by the present invention includes the gravity assisted heat pipe that can switch in the summer in winter in a kind of air-conditioning
Heat exchanger, including gravity heat pipe heat exchanger body, the gravity heat pipe heat exchanger body have the evaporation ends and position positioned at bottom
In the condensation end on top, the evaporation ends are mutually airtight with condensation end to isolate, it is characterised in that：
Respectively there is a lower plenum chamber in two outsides of evaporation ends, respectively have plenum chamber on, institute in two outsides of condensation end
State that lower plenum chamber and upper plenum chamber are mutually airtight to isolate；
The outside of one of them lower plenum chamber enters pipe with fresh air respectively by two lower valves and air draft outlet pipe is connected,
The outside of another lower plenum chamber enters pipe and is connected with fresh air outlet pipe and air draft respectively by two other lower valve；
The outside of plenum chamber enters pipe with the fresh air respectively by two upper valves and the air draft goes out on one of them
Pipe is connected, on another outside of plenum chamber by valve on two other respectively with the fresh air outlet pipe and the air draft
Enter pipe to be connected.
The technical solution adopted by the present invention also includes a kind of switching of the gravity heat pipe heat exchanger that can switch in the summer in winter in air-conditioning
Method, it has the gravity heat pipe heat exchanger that can switch in the summer in winter in above-mentioned air-conditioning, it is characterised in that：
Under summer mode, the valve that two upper plenum chambers and the fresh air enter between pipe and the fresh air outlet pipe is beaten
Open, and two upper plenum chambers and the air draft enter the valve closing between pipe and the air draft outlet pipe；Meanwhile, it is quiet under two
Pressure case and the fresh air enter the valve closing between pipe and the fresh air outlet pipe, and two lower plenum chambers enter with the air draft
Valve between pipe and the air draft outlet pipe is opened；
In the winter time under pattern, the valve that two upper plenum chambers and the fresh air enter between pipe and the fresh air outlet pipe is closed
Close, and the valve that two upper plenum chambers and the air draft enter between pipe and the air draft outlet pipe is opened；Meanwhile, it is quiet under two
The valve that pressure case and the fresh air enter between pipe and the fresh air outlet pipe is opened, and two lower plenum chambers enter with the air draft
Valve closing between pipe and the air draft outlet pipe.
Compared with prior art, the invention has the advantages that：Whether in summer or in the winter time, as long as cutting
Valve is changed, the evaporation ends of hotter airflow passes gravity heat pipe heat exchanger body, colder airflow passes gravity heat can be made
The condensation end of heat exchange of heat pipe body, it is ensured that gravity heat pipe heat exchanger body is in correct working condition all the time.So as to so that tool
The air-conditioning for having the gravity heat pipe heat exchanger can easily carry out the switching of summer in winter.
