Description
Technical field
The invention belongs to art of refrigeration units, be specifically related to a kind of dry evaporator.
Background technology
At present, in refrigeration, field of air conditioning, the commonly used dry type of refrigeration host computer in Large Central Air Conditioning System and freezing and refrigeration place
Shell-and-tube evaporator is as main heat transmission equipment, owing to dry evaporator has relatively low one-tenth relative to flooded evaporator
This, and use that the refrigerating unit structure of dry evaporator is succinct, it is simple, so dry evaporator is made widely to control
With.But along with society energy-conserving and environment-protective are required more and more higher, the Energy Efficiency Ratio how promoting refrigeration host computer then becomes particularly important,
And the heat exchange efficiency of vaporizer the most directly decides the Energy Efficiency Ratio of refrigeration host computer, but the Some features of dry evaporator self is led
The lifting causing its heat transfer efficiency is restricted, and causes the occasion much having higher requirements Energy Efficiency Ratio cannot use dry type shell
Formula vaporizer, becomes and uses the heat exchanger of other forms such as full-liquid type or falling film type.
But use full-liquid type or the refrigerating unit structure of downward film evaporator and control system the most complex, although its
Height wanted by heat exchange efficiency relatively conventional dry vaporizer, it is possible to obtain relatively low heat transfer temperature difference, thus improves the Energy Efficiency Ratio of refrigeration system,
But there is the problems such as fault rate is high, cost is high, refrigerant charge is big in it.If able to improve the heat exchange effect of dry evaporator
Rate, is combining the advantage of dry evaporator itself, and refrigeration unit uses dry evaporator to be undoubtedly optimal selection.
One of principal element affecting dry evaporator heat exchanger efficiency is exactly specification and the internal tooth form structure of heat exchanger tube, existing
Having dry evaporator many employings female thread high-performance heat exchanger pipe, dry blowing pipe specification all develops to small diameter, owing to diameter is little, and stream
Body can also be in turbulent condition under relatively low flow velocity, and under high flow velocities, turbulent condition is more violent, is conducive to improving spreading
Hot coefficient, so market achieves some Single-flow dry type evaporator using minor diameter dry blowing pipe now.
The another one principal element affecting dry evaporator heat exchanger efficiency is exactly the uniform distribution problem of cold-producing medium, as
Cold-producing medium is evenly distributed in every heat exchanger tube become a technical barrier by what.Typically face vaporizer bobbin carriage import department
Heat exchanger tube can be assigned to more cold-producing medium, the heat exchanger tube away from import department is then assigned to less cold-producing medium, position
The cold-producing medium that those heat exchanger tubes more on the upper side can be assigned to is the most less；The heat exchanger that particularly comb number is more, cold-producing medium
The phenomenon of maldistribution is particularly evident.
Existing flow equalization distribution device majority uses the mode of the current-sharing baffle plate of band mesh, and the current-sharing baffle plate of band mesh passes through
Change refrigerant flow direction, prevent cold-producing medium from directly rushing at just heat exchanger tube to import department, thus realize the effect of current-sharing distribution.But
Owing to cold-producing medium is the biphase state of air-liquid when entering vaporizer, the mode using common current-sharing baffle plate can only be to a certain degree
Alleviate the problem that distribution is uneven, the problem that but can not thoroughly solve uniform distribution.The most also occur that one utilizes all pressure chamber and hair
Tubule does the mode of current-sharing distribution, and cold-producing medium is introduced into all pressure chambeies and is assigned to each heat exchanger tube by the capillary tube on liquid-distributing plate again
In, the corresponding capillary of each pore, but the processing technique of liquid-distributing plate and capillary tube is complicated, and all pressure chamber and capillary tube all can
Cause bigger pressure drop, thus affect the Energy Efficiency Ratio of whole refrigeration system.
It addition, the above-mentioned scheme improving heat exchange property is all to realize by the way of improving tube side refrigerant side, but do not have
There is the situation considering shell side refrigerating medium side, though tube side refrigerant side distributed uniform, if the state of shell-side fluid is uneven,
Also the benefit brought due to tube side cold-producing medium distributed uniform cannot be realized, especially for the vaporizer of circular shell, shell side
Fluid is difficult to accomplish uniformly in housing section flow regime everywhere, even if using the mode of continuous helical deflecting plate also to be difficult to do
To the most uniformly, because the effect of centrifugal force still has bigger near casing center and the fluid flow state away from casing center
Difference, the design of deflection plate simultaneously adds the technology difficulty of refrigeration unit processing and manufacturing, especially for the housing that diameter is less,
Its difficulty of processing is bigger.
