Abstract
The utility model discloses the uniform chilled water coil of one kind heat exchange, belong to refrigerating machine technical field, heat exchange amount at the top and bottom of existing chilled water coil is small, intermediate heat transfer amount is big, overall heat exchange is uneven, heat exchange efficiency is poor, the utility model order is each more than the quantity of the heat-exchange tube included by each circuit in the middle part of chilled water coil positioned at the quantity of the heat-exchange tube included by the circuit of chilled water coil end, increase the heat exchange area in chilled water coil end circuit, the circuit heat exchange amount being effectively improved caused by wind speed inequality at the top and bottom of chilled water coil is small, intermediate loop heat exchange amount is big, the problem of chilled water coil overall heat exchange is uneven, improve the heat exchange efficiency in circuit at the top and bottom of chilled water coil, so that whole chilled water coil heat exchange is evenly.
Description
Technical field
The utility model belongs to refrigerating machine technical field, is specifically a kind of uniform chilled water coil that exchanges heat.
Background technology
Circuit You Ban circuits, full loop, the double loop of existing chilled water coil, and whole coil circuit is all identical.Identical
Under working condition, half circuit cold is maximum, and full loop cold is placed in the middle, and double loop cold is minimum.During concrete application, general windward side
The small coil pipe of product can select half circuit, and such cold can be some larger；The big coil pipe selection full loop of front face area；It is big again
Coil pipe reduce the resistance of water side to select double loop to be advisable.When coil size is big, wind meeting that top and bottom are passed through
It is fewer than centre, and the circuit of chilled water coil is the same, the water flow by each circuit is identical, and which results in cold water tray
Heat exchange amount at the top and bottom of pipe is small, and intermediate heat transfer amount is big, and overall heat exchange is uneven.
Utility model content
The technical problems to be solved in the utility model and the technical assignment proposed are to overcome existing chilled water coil top and bottom
The defects of heat exchange amount in portion is small, intermediate heat transfer amount is big, and overall heat exchange is uneven, heat exchange efficiency is poor, there is provided one kind heat exchange is uniform cold
Water coil.
In order to overcome drawbacks described above, the uniform chilled water coil of heat exchange of the utility model, it includes multiple circuits, each to return
Road includes multiple heat-exchange tubes being arranged in parallel being together in series, it is characterized in that：Each circuit institute for being located at chilled water coil end
Including the quantity of heat-exchange tube be more than the quantity of the heat-exchange tube included by each circuit in the middle part of chilled water coil.
As optimization technique means：The chilled water coil is plate-like, one side is windward side.
As optimization technique means：The both ends of all heat-exchange tubes are respectively assembled in a support plate.
As optimization technique means：The quantity of each heat-exchange tube positioned at included by the circuit on chilled water coil top with it is every
The quantity of a heat-exchange tube positioned at included by the circuit of chilled water coil lower part is identical.
As optimization technique means：The heat-exchange tube that each circuit includes is even number.
As optimization technique means：The quantity of each heat-exchange tube positioned at included by the circuit of chilled water coil end is 12
A, the quantity of the heat-exchange tube included by each circuit in the middle part of chilled water coil is 8.
The utility model order is each more than each positioned at the quantity of the heat-exchange tube included by the circuit of chilled water coil end
The quantity of the heat-exchange tube included by circuit in the middle part of chilled water coil, increases the heat exchange area in chilled water coil end circuit,
It is effectively improved that circuit heat exchange amount caused by wind speed inequality at the top and bottom of chilled water coil is small, intermediate loop heat exchange amount is big, cold water
The problem of coil pipe overall heat exchange is uneven, improves the heat exchange efficiency in circuit at the top and bottom of chilled water coil, so that whole cold water tray
Pipe exchanges heat evenly.
Brief description of the drawings
Fig. 1 is the schematic diagram in the heat exchange uniform chilled water coil end face direction of the utility model；
Figure label explanation：01- heat-exchange tubes, 02- are located at the circuit of chilled water coil end, and 03- is located in chilled water coil
The circuit in portion, 04- support plates.
Embodiment
The utility model is described further below in conjunction with Figure of description.
It is one embodiment of the uniform chilled water coil of the utility model heat exchange as shown in Figure 1, it includes multiple circuits, often
A circuit includes multiple heat-exchange tubes 01 being arranged in parallel being together in series（Circle shown in figure）, each it is located at cold water tray pipe end
The circuit 02 in portion（Represented in figure with the double dot dash line for heat-exchange tube 01 of connecting）The quantity of included heat-exchange tube is more than each
Circuit 03 in the middle part of chilled water coil（Represented in figure with the dotted line for heat-exchange tube 01 of connecting）The number of included heat-exchange tube
Amount.
Specifically, the chilled water coil is plate-like, one side（It is illustrated as left surface）For windward side.All heat-exchange tubes
Both ends be respectively assembled in a support plate 04, and by the heat-exchange tube swan neck in same circuit on the outside of support plate
（For clear expression circuit, swan neck is omitted in figure）Series connection.Each heat positioned at included by the circuit on chilled water coil top
The quantity of exchange pipe is identical with the quantity of each heat-exchange tube positioned at included by the circuit of chilled water coil lower part and is even number,
So that the water inlet in each circuit is respectively positioned on the side of chilled water coil, water outlet is respectively positioned on the opposite side of chilled water coil.As schemed
Show, the quantity of each heat-exchange tube positioned at included by the circuit of chilled water coil end is 12, is each located in chilled water coil
The quantity of heat-exchange tube included by the circuit in portion is 8.
The chilled water coil of diagram, left side are windward side, water outlet side, and right side is air side, influent side.
