Description
Technical field
This utility model relates to a kind of heat-exchanger rig, is specifically related to a kind of multifunctional gas-liquid comprehensive
Heat-exchanger rig.
Background technology
In refrigeration air-conditioner or chemical industry, can heat-exchanger rig high efficiency, many effects ground work
Work is to weigh one of advanced key factor of product technology.
Existing similar techniques has the tower heat-exchanger rig of cooling and evaporation cooling type heat-exchanger rig two kinds
Type.
When cooling down the work of tower heat-exchanger rig, liquid pump through jet pipe by Water spray to filler,
Under gravity, water flows along filler gap from top to down, at water from top to bottom
During flowing in filler gap, under the effect of fan, air is blowed to filler, real
Existing air works with the heat and mass transfer of water, and the water after being cooled is pooled in water storage tray, stores
The water of water pond is on the one hand for the water recirculation in cooling tower, on the other hand by water pipe for user
Use, from above-mentioned, cool down tower heat-exchanger rig mainly by the heat transfer of air Yu water
The function that water is cooled is achieved with effect of mass transmitting.
But cool down tower heat-exchanger rig to have the disadvantage that
1, tower heat-exchanger rig is cooled down cooled to liking water.In air conditioning unit application, also
Need additionally to increase external heat exchanger, realize cold-producing medium and water again by the heat exchanger increased
Heat exchange；
2, cool down tower heat-exchanger rig and be mainly incorporated as condensing unit use, owing to winter is low
Temperature Water Under easily freezes, therefore cools down tower heat-exchanger rig and be mainly suitable for making condenser use,
And it is not suitable as evaporator application to heat pump type air conditioner unit.
Evaporation cooling type heat-exchanger rig version and above-mentioned cooling tower heat-exchanger rig structure
Similar, Main change be by jet pipe below filler change into a kind of heat exchanger, or will
Filler plugs is between the gap of heat exchanger.Eliminate for outside pipe fitting simultaneously.
During work, its heat exchange mode from cool down tower heat-exchanger rig heat exchange mode the most different it
Place is that water is directly sprayed on heat exchanger by liquid pump, under gravity, water from upper and
Flow along heat exchanger gap, when water flows over along heat exchanger gap from top to down lowerly
Cheng Zhong, under the effect of fan, directly blows to heat exchanger by air, under the flowing of air,
Just air and the heat exchange of water and hyperphoric alteration, air and water also absorption heat-exchange device simultaneously are achieved
On heat, it is achieved that the function that the cold-producing medium in heat exchanger is cooled.
By above-mentioned operation principle it can be seen that evaporation cooling type heat-exchanger rig mainly passes through
Air and the heat exchange of water, realize the function that the cold-producing medium in heat exchanger is cooled simultaneously.
But there is following deficiency in it:
1, aqueous water is sprayed directly on heat exchanger, there is heat exchanger surface sprinkling uneven very
To spraying situation not in place, affect the heat transfer effect of heat exchanger.
2, aqueous water sprays on heat exchangers, and the outer surface at heat exchanger can form water membrane,
This layer of moisture film along in heat exchanger flow process from top to bottom, medium in absorption heat-exchange device
After heat, the temperature of moisture film can gradually rise, and reduces the heat transfer temperature difference of moisture film and heat exchanger,
The existence of moisture film simultaneously too increases the thermal resistance of water and heat exchanger, thus reduces water and heat exchange
The exchange capability of heat of the cold-producing medium in pipe.
3, during unit work, aqueous water sprays on heat exchangers, and unit quits work (or unloading)
Time, aqueous water also will stop spray function.This mode can cause the outer surface of heat exchanger to exist
It is wet during work, and when heat exchanger quits work, the outer surface of heat exchanger quickly becomes dry,
A this dry wet work phenomenon, the heat exchanger channels outer surface being easily caused heat exchanger forms water
Dirt and dirt, thus add the thermal resistance between heat exchanger tube and water so that the heat exchange of heat exchanger
Ability decays.
4, evaporation cooling type heat-exchanger rig is similar with cooling down tower heat-exchanger rig, evaporation cooling type
The condensing unit that heat-exchanger rig is mainly incorporated as in air conditioning system uses, owing to winter is at low temperature
Water Under easily freezes, therefore evaporation cooling type heat-exchanger rig is also not suitable for as evaporator application
On heat pump type air conditioner unit.
Owing to there is the deficiency of above several respects, the system of known evaporation cooling type heat-exchanger rig
Cryogen is insufficient with the heat exchange of water, air, thus it is air conditioning unit to reduce evaporating condensation type
Heat exchange property, affects air conditioning unit overall Energy Efficiency Ratio；And owing to winter is at cryogenic conditions
Lower water easily freezes, and evaporation cooling type heat-exchanger rig is mainly suitable for making condenser and uses, and uncomfortable
Cooperation is in evaporator application to heat pump type air conditioner unit；From above-mentioned, existing similar
Technology cools down tower heat-exchanger rig, and evaporation cooling type heat-exchanger rig not only heat exchange efficiency is the highest,
And the application in heat pump air conditioner there is also many technology barriers.
