Description
Technical field
The utility model relates to high temperature heat pump field, in particular to a kind of water route multipaths evaporator.
Background technique
Currently, being applied in water cooler on the market is shell-and-tube evaporator, which is placed on shell side
Two sides are equipped with several baffle plates in the outside of cylinder heat-transfer pipe, it is therefore an objective to make water is repeatedly horizontal to plunder pipe to increase the heat exchange of water side
Manifold flow is dynamic, improves the water side coefficient of heat transfer, but generally have the gap 1-3mm between baffle plate outer rim and shell, has between heat-transfer pipe
The gap of 2mm or so, thus will cause the leakage of water, the leakage of water can cause the water side coefficient of heat transfer to reduce 20%-30%, always
Heat transfer coefficient reduces 5%-15%.
Utility model content
In view of the above problems, more increase the purpose of this utility model is to provide a kind of raising coefficient of heat transfer and using unit
Effect stablizes and compact-sized and more economical water route multipaths evaporator.
To achieve the above object, a kind of water route multipaths evaporator provided by the utility model, wherein including shell side cylinder
Body is respectively equipped in the first tube sheet and the second tube sheet that shell-side cylinder both ends are respectively equipped with, on the first tube sheet and the second tube sheet
First end cover bobbin carriage and second end cover bobbin carriage, the first tube sheet and the second tube sheet inside shell-side cylinder between be equipped with it is a plurality of simultaneously
The interior round tube of row arrangement, the flow inlet being equipped on shell-side cylinder same side and water export, and on the first lid bobbin carriage
What is be equipped with changes Heating medium and heat exchange matchmaker outlet.Flow inlet and water export are set on the same end of shell-side cylinder；Right
Two will be separated into and separately includes inner circle by answering flow inlet and the shell-side cylinder of water export to be internally provided with inside shell-side cylinder
The partition of the chamber of pipe.Be equipped in the separated two chambers of partition be horizontally through in a plurality of parallel arranged round tube and be dislocatedly distributed in
Baffle plate inside shell-side cylinder.
In some embodiments, the first cavity is formed with the first tube sheet inside first end cover bobbin carriage；The second end
The second cavity is formed with the second tube sheet inside lid bobbin carriage.
In some embodiments, on the first lid bobbin carriage change Heating medium and heat exchange matchmaker outlet respectively with the first cavity phase
It is logical.
In some embodiments, partition both ends respectively with the first tube sheet and the second Tube-sheet Welding.
It improves the coefficient of heat transfer the utility model has the beneficial effects that having and uses unit more efficient stable and structure tight
It gathers and more economical effect.Since shell-side cylinder is divided into upper layer and lower layer chamber by partition, water in-out port is all in shell-side cylinder
The same end, upper layer and lower layer chamber are equipped with baffle plate, and water flow is flowed into from lower layer, and upper layer baffle plate is flowed into after baffle plate component
It is flowed out after component, such structure evaporator key is that shell side is divided into upper layer and lower layer with partition, doubles water-flow chart.
In this way, evaporator water-flow chart doubles, compensates for baffling outer rim and body clearance leakage causes the reduction of the water side coefficient of heat transfer,
But also the water side coefficient of heat transfer is improved, keep unit more efficiently and energy saving.Evaporator due to due to the water side coefficient of heat transfer improve, and
Volume itself does not increase, but refrigeration unit refrigerating efficiency improves, and more energy saving, occupied area is smaller.It realizes and is not changing
In the case where shell side length, water-flow chart is doubled.Water-flow chart increases, and improves the water side coefficient of heat transfer.The coefficient of heat transfer improves,
Structure is more compact, minimizes, and reduces the occupied area of unit.

Specific embodiment
Utility model is described in further detail with reference to the accompanying drawing.
As shown in figures 1 to 6, a kind of water route multipaths evaporator, including shell-side cylinder 1, set respectively at 1 both ends of shell-side cylinder
The first tube sheet 2 and the second tube sheet 3 that have, the first end cover bobbin carriage 4 and being respectively equipped on the first tube sheet 2 and the second tube sheet 3
The interior round tube of a plurality of parallel arranged is equipped between two end cap bobbin carriages 5, the first tube sheet 2 and the second tube sheet 3 inside shell-side cylinder 1
6, the flow inlet 7 and water export 8 being equipped on 1 same side of shell-side cylinder, and the heat exchange being equipped on the first lid bobbin carriage
Matchmaker's import 9 and heat exchange matchmaker outlet 10.Flow inlet 7 and water export 8 are set on the same end of shell-side cylinder 1；In corresponding water
The shell-side cylinder 1 for flowing into mouth 7 and water export 8 is internally provided with and will be separated into two inside shell-side cylinder 1 and separately include inner circle
The partition 11 of the chamber of pipe 6.It is equipped in the separated two chambers of partition 11 and is horizontally through round tube 6 and mistake in a plurality of parallel arranged
Baffle plate 12 of the bit distribution inside shell-side cylinder 1.4 inside of first end cover bobbin carriage forms the first cavity with the first tube sheet 2；It is described
The inside of second end cover bobbin carriage 5 form the second cavity with the second tube sheet 3.Heating medium 9 and heat exchange matchmaker are changed on first lid bobbin carriage
Outlet 10 is communicated with the first cavity respectively.It is welded respectively with the first tube sheet 2 and the second tube sheet 3 at 11 both ends of partition.
Partition 11 divides shell-side cylinder 1 for upper layer and lower layer chamber, and water in-out port is all in the same end of shell-side cylinder 1, up and down
Two layers of chamber is equipped with baffle plate 12, and water flow is flowed into from lower layer, and baffle plate 12 component in upper layer is flowed into after 12 component of baffle plate
After flow out, such structure evaporator key is that shell side is divided into upper layer and lower layer with partition 11, doubles water-flow chart.Such as
This, evaporator water-flow chart doubles, and it compensates for baffling outer rim and body clearance leakage causes the reduction of the water side coefficient of heat transfer, and
And the water side coefficient of heat transfer is also improved, keep unit more efficiently and energy saving.Evaporator is since the water side coefficient of heat transfer improves, and this body
Product does not increase, but refrigeration unit refrigerating efficiency improves, and more energy saving, occupied area is smaller.It realizes not change shell side long
In the case where degree, water-flow chart is doubled.Water-flow chart increases, and improves the water side coefficient of heat transfer.The coefficient of heat transfer improves, and structure is more
Step up to gather, minimize, reduces the occupied area of unit.
Working principle is: shell-side cylinder 1 is divide into upper part and lower part, and is bottom in and top out in terms of water flow；Water flow is in shell side lower part
Point do it is horizontal plunder tube bundle flowing after enter upper part, done in upper part and horizontal plunder tube bundle flowing；Water-flow chart is doubled, water is improved
The side coefficient of heat transfer, and evaporator is then more compact, miniaturization.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical new
The protection scope of type.
