Description
Technical field
The utility model relates to the automobile air-conditioning refrigeration technology, relates in particular to a kind of refrigerating plant that is used for cooling in the carriage of electric automobile.
Background technology
Electric automobile air-conditioning employing both at home and abroad all is the motorized motions compressor air-conditioning at present, mainly form by devices such as compressor, condenser, throttling arrangement, evaporimeters, during air conditioner refrigerating, compressor of air conditioner extracts cold-producing medium to deliver to after compression to cool off in the condenser and condenses from evaporimeter, give out heat in air by fin, cold-producing medium is also from the gaseous state liquefy, and pressure raises.Cold-producing medium is ejected in the evaporimeter after passing through the throttling arrangement throttling again from condenser, and pressure drop, liquid refrigerant become gaseous state immediately, absorb a large amount of heat in the air by fin.Like this, compressor of air conditioner is constantly worked, and just constantly the heat absorption of evaporimeter one end is delivered to condenser in the cold-producing medium again and is dispersed in the air, and at this moment cold-producing medium is from indoor heat absorption, outdoor heat release, and circulation is gone down, and indoor temperature is just reduced.
Compressor of air conditioner is to play the compressible drive cold-producing medium in the air-conditioning refrigerant loop, it is the core component of whole air-conditioning system, because its complicated integral structure, quality is heavy, energy consumption is big, easily makes electric automobile reduce continual mileage, needs to use special lubricating oil, increase operating cost, and maintenance is used also very inconvenient.Matching used with it chemical refrigerant (as freon etc.), very big to the harm of environment, be unfavorable for environmental protection and safety, be not suitable for being used on the object that as electric automobile, is about to popularize.Though obtain some progress through continuous research at present, its effect is also very unsatisfactory.
The utility model content
The purpose of this utility model is to provide a kind of refrigerating plant that is used for cooling in the carriage of electric automobile that does not need to use compressor and any chemical refrigerant and special lubricating oil.
This refrigerating plant that is used for cooling in the carriage of electric automobile of the present utility model, comprise housing, cold water storage cistern, water pump, blower fan, air channel, evaporation tank, semiconductor cooler are arranged in the described housing, and described cold water storage cistern is connected with evaporation tank by water pump, and cold water is sent in the evaporation tank; The blowing direction of blower fan is facing to evaporation tank, and the cold wind of formation enters semiconductor cooler along described air channel and further cools off, and the cold air of formation enters in the automobile bodies by the air channel.
The ice crystal box is arranged in the described cold water storage cistern.
This refrigerating plant of the present utility model, when refrigeration, utilize cold water and ice to be medium circulation cooling air mode, allow cold wind that blower fan blows through once cooling earlier, arrive good refrigeration, by the method for radiator on the semiconductor cooler and air gasification refrigeration, can effectively improve refrigeration again.The utility model is by the once refrigeration of water circulation and the secondary refrigeration of semiconductor cooler, good refrigeration effect, compressor and any chemical refrigerant and special lubricating oil had both no longer been needed to use, make air obtain purification again, occupation mode is simple, and power consumption is little, and cost is low, long service life is more conducive to environmental protection and energy saving.

The specific embodiment
As can be seen from Figure 1, this refrigerating plant that is used for cooling in the carriage of electric automobile of the utility model, comprise housing 1, cold water storage cistern 2, water pump 3, the blower fan 13 of ice crystal box are housed, air channel 11, evaporation tank 12, semiconductor cooler 4 are arranged in housing 1, the delivery port of described cold water storage cistern 2 is connected with evaporation tank 12 by water pump 3, and cold water is sent in the evaporation tank 12; The blowing direction of blower fan 13 is facing to evaporation tank 12, and the cold wind of formation enters semiconductor cooler 4 along described air channel 11 and further cools off, and the cold air of formation enters in the automobile bodies by air channel 11.
For the temperature that still can preserve value after cold water storage cistern 2 interior water are repeatedly recycled does not raise, between the water inlet and evaporation tank 12 of cold water storage cistern 2, also be connected with a temperature control radiator 15, this temperature control radiator 15 comprises fan, ice crystal box and temperature detect switch (TDS).
As can be seen from Figure 2, the semiconductor cooler 4 that is adopted in the utility model, comprise two dividing plates 41 and the isolation frame 42 that lays respectively on two division boards 41, thermal isolation film 43, semiconductor 44, two dividing plates 41 are divided into three passage aisles with the air channel 11 of housing 1, the one side of two semiconductors, 44 refrigeration is towards the middle air channel of housing 1, two sides at semiconductor 44 respectively is equipped with fin 45, the center-aisle in air channel 11 is a refrigerating channel, the air inlet 46 in air channel in the middle of its bottom is provided with, the top connects the interior air outlet 47 of cold air, cold air is blown into secondary refrigeration the semiconductor cooler 4 from air inlet 46, is blown out by air outlet 47 again; Two wing passages in air channel 11 are for heating passage, and its bottom links with the front end in air channel 11, and the top is connected with outer air outlet 48 with main air port respectively, and outer air outlet 48 is connected outward with car.
The utility model in use, at first cold water and ice cube will be filled with in the cold water storage cistern 2, water pump 3 sucks cold water in insulating tube input evaporation tank 12, evaporation tank 12 surface temperatures descend rapidly, simultaneously, the air that blower fan 13 blows, pervaporation case 12 surfaces continue to flow, air obtains the heat absorption cooling, when its temperature of the water that flows through evaporation tank 12 is not raised to certain value, temperature detect switch (TDS) on the temperature control radiator 15 cuts out, and the water in the evaporation tank 12 is in insulating tube, control valve flow back to cold water storage cistern 2, under the effect of water pump 3 and recycle.When the water that flows through evaporation tank 12, when temperature is raised to certain value and is not enough to freeze, temperature detect switch (TDS) on the temperature control radiator 15 is opened automatically, after insulating tube, control valve enter in the cold water storage cistern 2 and recycle, this is process of refrigerastion of ice water circulation to water through 15 heat radiations of control valve, temperature control radiator.
