Description
Technical field:
The utility model relates to a kind of field of heat exchangers, are especially a kind of parallel-flow heat exchanger with changes in temperature effect.
Background technique:
Heat exchanger of air conditioner has generallyd use copper pipe pipe sheet type structure at present, and wherein copper pipe tube-fin condenser is due to main
The valence of material copper is higher, and structure type is changed there are thermal resistance leads to that the thermal efficiency is low, reasons have lost the big total weight of volume gradually again etc.
Its competitive advantage.Micro-channel heat exchanger technology is quickly grown in recent years, and micro-channel heat exchanger is as a kind of new type heat exchanger, in vapour
Vehicle field of air conditioning is widely used, but its application range is only limitted to as condenser, and is not suitable for making evaporator, because in the presence of
Following problems: when being used as evaporator, what refrigerant flowed in the core evenly distributes problem；2, frosting, defrosting and condensed water
Stool problems.
Utility model content:
That technical problem to be solved by the utility model is to provide a kind of refrigerants is evenly distributed, improves heat exchange property, and
And also it is able to satisfy the parallel-flow heat exchanger with changes in temperature effect of the requirement of cooling and warming bidirectional shunt uniformity.
The technical solution of the utility model is to provide a kind of parallel-flow heat exchanger with changes in temperature effect, including
One header and the second header, and be connected between the first header and the second header and with the first header and second
Several flat tubes of header connection, the first header and the second header both ends pass through end cap respectively and are blocked, and further include the
One conduit and the second conduit, the first tube at one end through the first header end cap and extend internally, the second header it is separate with
The side of the side of flat tube connection is equipped at intervals with several through-holes along its length, and the second conduit is arranged parallel with the second header
And be fixed on the second header side, the second conduit is connected to the through-hole of the second header, the second conduit it is closed at one end.
After using the above structure compared with prior art, the utility model has the advantage that so that refrigerant distribution is equal
Even, raising heat exchange property, and also it is able to satisfy the requirement of cooling and warming bidirectional shunt uniformity.
Preferably, the length of the second conduit is greater than the length of the second header, one end of the second conduit and the second afflux
One end of pipe flushes.
Preferably, the end of one end that the second conduit is flushed with the second header is closed end
Preferably, the cross section for the part that the second conduit is connect with the second header be semicircle, the second conduit it is straight
Diameter of the diameter less than the second header.
Preferably, the through-hole on the second header is evenly spaced on, and the quantity of through-hole is identical as the quantity of flat tube,
The spacing of adjacent through-holes is consistent with the spacing of adjacent flat tube.
Further, the straight flange edge of the second conduit is extended weld part, and the weld part and the second afflux pipe surface are welded.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the second header and the second conduit.
Specific embodiment:
The utility model is described in further detail with reference to the accompanying drawings and detailed description:
As shown in Figs. 1-2, a kind of parallel-flow heat exchanger with changes in temperature effect, including the first header 1 and the second afflux
Pipe 2, and be connected between the first header and the second header and be connected to the first header and the second header several
Flat tube 3, the first header 1 and 2 both ends of the second header pass through end cap respectively and are blocked, and further include the first conduit 4 and second
Conduit 5,4 one end of the first conduit run through the end cap of the first header and extend internally, and the both ends of the first conduit 4 are open end,
The side of the separate side being connected to flat tube of second header 2 is equipped at intervals with several through-holes 6, the second conduit 5 along its length
It is arranged and is fixed on the second header side parallel with the second header 2, the second conduit 5 is connected to the through-hole of the second header 2,
Second conduit 4 it is closed at one end.
Specifically, the length of the second conduit 5 is greater than the length of the second header 2, one end of the second conduit 5 and the second afflux
One end of pipe 2 flushes, and the end of one end that the second conduit 5 is flushed with the second header is closed end, 5 other end of the second conduit
For open end.Further to improve, the through-hole on the second header 2 is to be evenly spaced on, and the quantity of through-hole and flat tube
Quantity is identical, and the spacing of adjacent through-holes is consistent with the spacing of adjacent flat tube, in this way, the refrigerant entered by through-hole is matched with flat tube
It closes more preferable.In order to facilitate fixation, the cross section for the part that the second conduit 5 is connect with the second header 2 is semicircle, the second conduit
5 diameter is less than the diameter of the second header 2, and the straight flange edge of 5 open side of the second conduit is extended weld part 7, and weld part 7 can
2 surface of the second header is welded in the form of skirt.
This structure is in heating as condenser, and in refrigeration as evaporator, the course of work is as follows: as evaporator
When: refrigerant enters the second header by the through-hole of the second header from the second conduit with liquid condition, passes through the flat of connection
Pipe, is discharged evaporator into the first header, then from the first conduit in gaseous form.When as condenser: refrigerant is with gas
State enters the first header from the first conduit, by the flat tube of connection, enters second into the second header, then by through-hole
Conduit flows out condenser in liquid form.
The utility model has the advantage that so that refrigerant is evenly distributed, improves heat exchange property, and is also able to satisfy system
The requirement of cold heating bidirectional shunt uniformity.
Only the utility model preferred embodiment is described above, but is not to be construed as the limit to claim
System.All equivalent structure or equivalent flow shifts done using the utility model specification and accompanying drawing content are included in this
Within the scope of patent protection of utility model.
