Agent channel is respectively two mutually independent metallic conduits, and the section of the metallic conduit at least has a straight flange, two gold
The straight flange of metal conduit is close to each other and there are gap, and gap width is less than 1.5mm, it is preferable that the gap width is less than or equal to
1.0mm is filled with heat transfer medium layer in the gap.
Further, safe and efficient parallel heat exchange device further includes heat exchanger shell, the coolant channel and refrigerating medium
Channel is located in shell heat exchanger body, is also filled with conduction oil in the shell heat exchanger body, is located at coolant channel and refrigerating
Conduction oil between agent channel forms heat transfer medium layer.
Further, the section of the coolant channel is in long strip, and inside is formed multiple by several partitions of setting
Metallic micro channel.The coolant channel is aluminium alloy pipeline, and the refrigerating medium channel is TP2 copper pipe.
Safe and efficient parallel heat exchange device provided by the present application can be applied to air friction drag, air-source cold water
In unit or water source water cooler, single group is used or multiple groups are used in parallel.
The invention discloses a kind of safe and efficient parallel heat exchange devices, change previous coolant channel and refrigerating medium channel
Coolant channel and refrigerating medium channel are independently arranged the design method mutually to socket-connect, and pre- between two passes
Stay the gap of prolate to fill heat transfer medium layer.The heat transfer medium layer added can shield for coolant channel,
It is avoided to rupture because of ambient temperature effect.

Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to design of the invention, specific structure and generation clear
Chu is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair
Bright a part of the embodiment, rather than whole embodiments, based on the embodiment of the present invention, those skilled in the art are not being paid
Other embodiments obtained, belong to the scope of protection of the invention under the premise of creative work.In addition, be previously mentioned in text
All connection/connection relationships not singly refer to that component directly connects, and referring to can be added deduct according to specific implementation situation by adding
Few couple auxiliary, to form more preferably coupling structure.Each technical characteristic in the invention, in not conflicting conflict
Under the premise of can be with combination of interactions.
As shown in Figure 1, a kind of safe and efficient parallel heat exchange device, including coolant channel 1, refrigerating medium channel 2 and Re Jiao
Exchanger shell 3, the coolant channel 1 and refrigerating medium channel 2 are respectively two mutually independent aluminium alloy pipelines and TP2 copper pipe
The section in road, the coolant channel 1 is in long strip, internal to form multiple metallic micro channels by the way that several partitions are arranged
11,2 section of refrigerating medium channel is equally in long strip, but partition can be not provided with inside it, coolant channel 1 and refrigerating medium
The straight flange in channel 2 is close to each other and there are the gap of 1.5mm spacing 4, the coolant channel 1 and refrigerating medium channels 2 to be located at heat
3 in exchanger shell, it is also filled with conduction oil 5 in the heat exchanger shell 3, is located at coolant channel 1 and refrigerating medium channel 2
Between conduction oil 5 formed heat transfer medium layer.
1. heat exchange area is increased using microchannel (identical volume, than present circular pipe structure), thus
Reduce volume, reduces cost.2. safety, since refrigerating medium channel and coolant channel are channels independent, conduction
Thermal energy is the transmitting that thermal energy is carried out by the conduction oil interval below 1.5mm, so, when refrigerating medium channel due to microthermal climate or
When water pump power disappears (in cold energy transmitting), refrigerating medium (water) will be because steaming when environment temperature is less than 0 DEG C or when cold energy exchanges
When sending out temperature less than 0 DEG C, channel is burst due to refrigerating medium (water) volume becomes larger caused by freezing in refrigerating medium channel.Due to causing
Coolant channel and the not hard contact of refrigerating medium interchannel, will not be because of refrigerating medium channel after refrigerating medium channel is burst because of icing
It ruptures and refrigerating medium (water) is caused to mix with refrigerant, it is swollen because of the icing of refrigerating medium channel so as to avoid two kinds of different mediums
It is mixed after broken and the refrigerant circulating system and refrigerating medium water of arrive entire heat pump and operation of air conditioning systems or air-conditioning heat pump equipment
It mixes, to ensure that therefore heat pump and operation of air conditioning systems or air-conditioning heat pump equipment are not scrapped.
It is empty for air-source or water source heat pump water heater, low temperature heat collector and water-cooled that the object of the present invention is to provide one kind
Twin-channel safe and efficient parallel heat exchange device of gas adjuster, when air-source or water source heat pump water heater, low temperature heat collector and
Water-cooled air conditioner uses such safe and efficient parallel heat exchange device, the dosage of non-ferrous metal can be reduced, due to refrigeration
Agent channel uses microchannel, improves heat exchanger effectiveness.Since coolant channel and two channel of refrigerating medium channel being designed
At being placed in parallel, the spacing distance of interchannel is to make heat transfer medium less than 1.5mm distance, and using conduction oil, to reduce
Heat loss when heat exchange.Because be binary channels design and its between have the soft contact of conduction oil, form between two channels
There are three interlayers every with sufficient anti-swelliong power, to guarantee that the refrigerating medium (water) in refrigerating medium channel is unlikely to because of icing
Refrigerant and refrigerating medium is caused to mix and cause air-source or water source heat pump water heater, low temperature heat collector and water-cooling air tune
Section device is damaged and is scrapped.
Better embodiment of the invention is illustrated above, but the invention is not limited to the implementation
Example, those skilled in the art can also make various equivalent modifications on the premise of without prejudice to spirit of the invention or replace
It changes, these equivalent variation or replacement are all included in the scope defined by the claims of the present application.
