The specific embodiment
Industrial, the air-conditioning that is used to reduce regulator cubicle or switch board in-cabinet temperature in use, just there is seasonal variation in the inside and outside temperature of cabinet, in 1 year, the time that in-cabinet temperature is higher or lower than the outer temperature of cabinet much at one.At this situation, the present invention proposes a kind of economical air conditioner to be thinking at the inner integrated heat pipe heat exchanger of conventional vapour compression refrigeration air-conditioner.
Heat pipe is a kind of heat transfer element with high thermal conductivity, its evaporation by working medium in the Totally enclosed vacuum shell is transmitted heat with condensing, but the heat transfer area with high thermal conductivity, good isothermal, cold and hot both sides can change series of advantages such as remotely transferring, temperature controllable arbitrarily.The heat exchange of heat pipe of forming by heat pipe have heat transfer efficiency height, fluid resistance decrease little, help controlling advantage such as dew point corrosion, and the heat exchange of heat pipe compressor-free does not need freon working medium, its compact conformation, quality and profile are less.
The operation principle of heat pipe is to utilize the evaporation of working fluid and condensation to transmit heat.The working fluid of heat pipe is different according to composition and ratio, is divided into a few class heat pipes such as low temperature, middle gentle high temperature, and comparatively common working fluid has ammonia, water, acetone and methyl alcohol etc.The heat pipe two ends are divided into evaporation ends (fire end) and condensation end (radiating end), take adiabatic measure between the two ends as required, working fluid vaporization in the pipe when heat pipe evaporation ends is heated, absorb heat of vaporization from thermal source, vaporization back steam flows and meets the condensation knot and emit latent heat to radiating area to the opposite side condensation end, condensate liquid borrows the effect of capillary force or gravity to reflux, vaporization continues to be heated, the reciprocation cycle conduction that the phase transition process of heat by working medium carries out in the heat pipe is delivered to radiating area with a large amount of heats from the thermal treatment zone like this.
The transfer of heat of heat exchange of heat pipe need be carried out existing under the condition of the temperature difference, it is integrated in air-conditioner, when operating temperature is higher in, the cabinet lower when switch board external environment temperature, heat exchange of heat pipe just can utilize the heat radiation of cabinet internal-external temperature difference, the in-cabinet temperature of industrial common equipments such as regulator cubicle, switch board is reduced, play thermoregulatory effect.And this temperature difference is big more, and the heat radiation power of heat exchange of heat pipe is just big more.This has not only saved the energy, and has prolonged air-conditioning unit service life of critical component such as compressor particularly.
At the highdensity radiating fin of heat pipe appearance cross-under, can reduce the volume of heat exchange of heat pipe significantly, improve radiating efficiency simultaneously greatly.But also there is the use limitation in heat exchange of heat pipe, and its operation principle relies on the cabinet internal-external temperature difference, and the reduction of in-cabinet temperature can't be effectively controlled.During the broiling summer or environment temperature very high the time, in the time of realizing the reverse transfer of heat, heat exchange of heat pipe almost lost efficacy.Therefore, heat exchange of heat pipe is integrated on the existing switch board air-conditioner, will greatly improves the quality of air-conditioner efficient energy-saving.
In the prior art, the refrigeration system of regulator cubicle, switch board air-conditioner is a kind of steam compression type refrigeration circulatory system, is used for Industry Control cabinet, regulator cubicle etc. are carried out temperature control.This refrigeration system comprises compressor, evaporimeter, condenser, restricting element and electric component etc., and evaporimeter and condenser are furnished with blower fan respectively and are provided with separately air channel.After heat exchange of heat pipe is integrated into this class air-conditioner, the compound use of two cover refrigeration systems, how many structure size of heat exchange of heat pipe can setting according to the heat exchange amount.Air conditioner control system judges that according to factors such as temperature in environment temperature and the rack starting the steam compression type refrigeration circulatory system still is the heat pipe heat exchanging system, and perhaps two cover systems move simultaneously.Like this, can make the air-conditioner unit externally avoid starting compressor under the colder situation of operating mode, perhaps reduce the compressor start number of times.And during the broiling summer or environment temperature higher the time, rely on the compressor cooling EGR and do not start heat exchange of heat pipe.
