Description
Technical field
This utility model is related to a kind of multi channel heat exchanger, more particularly, it relates to a kind of be used as the many of vaporizer
Channel heat-exchanging.
Background technology
In the art, when heat exchanger is used in as vaporizer, the refrigerant suction in liquid phase is derived from ambient air stream
Heat and be transformed into gas from liquid.In the process, local expand two phase refrigerant enter heat exchanger and start to
Upper flowing.Then, cold-producing medium continue expand and constant absorption be derived from air stream heat, thus reach at the top of coil pipe overheated
State.In order to protect compressor, liquid must seethe with excitement completely to be become gas and continues heating until overheated, thus ensureing cold-producing medium
Must could enter compressor in gas phase.
Because cold-producing medium flows up, the temperature of cold-producing medium is relatively low in the bottom of coil pipe, and at the top of coil pipe is then
Heat.Now, in order to ensure Temperature Distribution being laterally uniform, those of ordinary skill in the art generally adopt heat distribution and
Collection device quickly will not be reached than other positions due to the momentum of fluid and system dynamic come the side to guarantee coil pipe
Heat.But in actual application, often cannot obtain desired technique effect.Flow direction due to multi channel heat exchanger
Unanimously, the problems referred to above are especially prominent.
It is known that the inhomogeneities of Temperature Distribution can lead to heat transfer efficiency to reduce and therefore reduce the efficiency of refrigeration system
And capacity.In addition, also result in the cold-producing medium in liquid phase to enter compressor and compressor is had a negative impact, such as compress
Easily be corroded inside machine oxidation, refrigerating efficiency declines to a great extent.
Therefore, urgent need design is a kind of avoids temperature distributing disproportionation even and guarantees to be in only the cold-producing medium entrance compressor of gas phase
Multi channel heat exchanger.
Content of the invention
The purpose of this utility model is to provide and a kind of avoid temperature distributing disproportionation even and guarantee to be in only the cold-producing medium of gas phase
Enter the multi channel heat exchanger of compressor.
This utility model is related to a kind of multi channel heat exchanger, including：Supply manifold, cold-producing medium is supplied by this supply manifold
To in multi channel heat exchanger；Discharge manifold, cold-producing medium is discharged from multi channel heat exchanger by this discharge manifold；And it is multiple
Passage, these passages flow wherein for cold-producing medium, and at least a portion passage in multiple passages is connected with supply manifold, and many
Other passages in individual passage connect with discharging manifold, and wherein, cold-producing medium is in the adjacency channel in multiple passages along contrary
Flow in direction.
It is preferred that multi channel heat exchanger can be equipped with supply manifold in both sides and discharge manifold.
In an embodiment of the present utility model, it is arranged on the supply manifold of multi channel heat exchanger both sides and discharges discrimination
Guan Jun is arranged to coaxial configuration, and wherein supply manifold is coaxially disposed in the inside discharging manifold.
In another embodiment of the present utility model, it is arranged on supply manifold and the discharge of multi channel heat exchanger both sides
Manifold is all arranged to coaxial configuration, is provided with the supply manifold in multi channel heat exchanger side and is coaxially disposed in discharge discrimination
The inside of pipe, and the discharge manifold being arranged on multi channel heat exchanger opposite side is coaxially disposed in the inside of supply manifold.
Or, multi channel heat exchanger only can also be provided with supply manifold in side and discharge manifold.
In further embodiment of the present utility model, multi channel heat exchanger is also provided with, in opposite side, discrimination of turning back
Pipe, manifold of turning back is exchanged so that entering Multi-channel hot by supply manifold with all channel connections in multi channel heat exchanger
The cold-producing medium of device is turned back at manifold of turning back and is passed through to discharge manifold discharge.
In another embodiment of the present utility model, it is arranged on supply manifold and the discharge of multi channel heat exchanger side
Manifold is arranged to coaxial configuration, and wherein, supply manifold is coaxially disposed in the inside discharging manifold.
