Description
Technical field
The utility model is related to technical field of heat exchangers more particularly to a kind of falling film type plate heat exchangers.
Background technology
At present, heat-exchanger rig is broadly divided into two kinds of tubular heat exchanger and plate heat exchanger, and in identical flow resistance
Under pump power Expenditure Levels, the heat transfer coefficient of plate heat exchanger is three to five times higher than shell and tube cooler, and shell and tube changes
Hot device, which is primarily present, to be taken up a large area, makes the shortcomings of complicated, easy cleaning, heat loss be not big, capacity is smaller, easy fouling, therefore
Now mostly using plate heat exchanger, but the plate of existing plate heat exchanger is easily deformed, and heat exchange efficiency is low.
Utility model content
The purpose of this utility model is to provide a kind of falling film type plate heat exchanger, solves and of the prior art solves spray
Leaching is not enough uniformly and the technical issues of plate pressure-bearing yielding problem.
Including shell, multiple hot-water cavities, phase are separated into inside the shell by plate for a kind of falling film type plate heat exchanger
Input duct is provided between the adjacent hot-water cavity, and the hot-water cavity is internally provided with support filler, the input duct
Multiple nozzles are arranged at intervals with, and heat transfer zone is formed between input duct and hot-water cavity, the plate of the nozzle and the hot-water cavity
Piece is corresponding.
Based on the above technical solutions, the utility model can also do following improvement：
Further, the nozzle is located at input duct both sides respectively, and the advantageous effect using this step is to improve heat exchange effect
Rate.
Further, the support filler is grid palisade, and the advantageous effect using this step is by supporting filler can
Ensure the stability of plate, it is ensured that plate will not deform.
Further, it further includes collecting chamber, and the collecting chamber is arranged on inside shell, and collecting chamber is located under hot-water cavity
Side, the advantageous effect using this step is that hot water is collected using collecting chamber.
Further, it further includes multiple collection conduits and refrigerant exit pipe, the collection conduit and heat transfer zone bottom phase
Connection, and collection conduit is connected with the refrigerant exit pipe, the refrigerant exit pipe is arranged on inside collecting chamber, the refrigerant
Outlet is located on the outside of shell, and the advantageous effect using this step is to be transferred out refrigerant concentration after heat exchange by refrigerant exit pipe
It goes.
The beneficial effects of the utility model：
The utility model is a kind of falling film type plate heat exchanger, by being provided with grid-like fill out between adjacent plate
Material supports plate with this, improves the compressive resistance of plate, prevent plate from deforming, so can be ensured that the stability of heat exchanger fin；This
Utility model is simple in structure, service life is long, and solves the problems, such as that spray is not uniform enough and plate pressure-bearing is yielding.
