Abstract
The invention relates to a fan coil, in particular to a heat pipe heat exchange-based constant temperature fan coil. In the fan coil, a heat pipe with fins is used as a heat exchange coil, and a heat exchange area is reduced by phase change heat exchange, so that the contour dimension of the fan coil is reduced; and the temperature of room air is controlled automatically by setting the phase change temperature of a heat pipe medium and utilizing the heat switch principle of the heat pipe, so that the complex degree of temperature control over the fan coil is reduced.
Description
Technical field
The present invention relates to be applied to a kind of fan coil, especially a kind of thermostatic type fan coil based on heat pipe heat exchanging.
Background technology
As a kind of terminal heat transmission equipment of central air conditioner system of maturation, fan coil occupies a tiny space at people's life and industrial circle.Universal day by day along with central air-conditioning product and technology, fan coil is subject to people's attention by feat of advantages such as price material benefit, easy to use, dependable performance, flexible arrangement.At present, fan coil product on the market is comparative maturity, needs improvements but still have.On the one hand, existing fan coil adopts no phase-change heat-exchange, causes the heat exchange coil area bigger, makes that the fan coil overall dimensions is bigger, has taken more space.On the other hand, modern Automatic Control Component is adopted in the control of air themperature more and more, though improved automaticity, has also increased cost, complexity and fault rate.
Summary of the invention
The objective of the invention is: 1, solve the excessive problem of heat exchange coil area in the existing fan coil; 2, optimize the temperature control model of existing fan coil.Provide a kind of and adopted phase-change heat-exchange, reduced heat exchange area, utilized the thermal switch principle of heat pipe to carry out the thermostatic type fan coil that air themperature is controlled.
Purpose of the present invention can reach by following measure:
1, adopt finned heat pipe as heat exchange coil, heat transfer mechanism is a phase-change heat-exchange, and same heat exchange amount only needs heat exchange area still less.
2, the medium phase transition temperature in the heat pipe is controlled at proper level, makes and have only when external air temperature is higher than this phase transition temperature value that heat pipe is just brought into play the effect of transmitting heat.The thermal switch principle of Here it is heat pipe.
The setting of above-mentioned heat exchange module had both solved the excessive problem of heat exchange coil area in the existing fan coil, made that also the control of room air temperature is simple more, was easy to realize, had reduced cost, complexity and fault rate.
Beneficial effect of the present invention:
The present invention has adopted a kind of brand-new phase-change heat-exchange, has utilized phase transition temperature to control the pattern of room air temperature automatically, overcome the defective that existing fan coil size is big, temperature control is complicated, can improve the overall performance of existing fan coil to a certain extent.
Description of drawings
Fig. 1 is Flat Architecture figure of the present invention.
Fig. 2 is a side view of the present invention.
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
Core of the present invention is finned heat pipe heat exchanging module, with reference to exemplary plot 1 and Fig. 2.Among Fig. 1 and Fig. 2, (1) is blower fan, and (2) are heat pipe evaporator section, and (3) are the heat pipe section of condensing, and (4) are the heat pipe fin, and (5) are the chilled water interface, and (6) are the fan coil shell, and six parts constitute the thermostatic type fan coil jointly.This structure is applicable to central air-conditioning room in summer.During fan coil work, blower fan (1) is operation continuously, extracts space air, through heat pipe evaporator section (2), blows to the room again, and space air constantly circulates, and the fans entrance temperature is as the representative of room air temperature.When the fans entrance temperature was lower than the heat-pipe medium phase transition temperature, heat pipe was not worked, and did not have the heat transmission, had only the air circulation circulation.When the fans entrance temperature was higher than the heat-pipe medium phase transition temperature, the heat pipe evaporator section medium underwent phase transition, and absorbed heat in the air, reduced air themperature, and heat is delivered to the heat pipe section of condensing (3), by condensing of medium heat was passed to chilled water.When the fans entrance temperature drops to the heat-pipe medium phase transition temperature when following, heat pipe is not worked once more.Because the phase transition temperature of medium can be redefined for steady state value in the heat pipe, heat pipe has just played the effect of a heat exchange switch, can more easily realize the control to room temperature.
Claims (1)
1. thermostatic type fan coil based on heat pipe heat exchanging, it is characterized in that: it with finned heat pipe as heat exchange coil, be made up of blower fan (1), heat pipe evaporator section (2), the heat pipe section of condensing (3), heat pipe fin (4), chilled water interface (5), fan coil shell (6), each several part is formed the thermostatic type fan coil jointly.
