The orientation or position relationship shown, is for only for ease of description the utility model and simplifies description, rather than indicate or imply and be signified
Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this practicality
The limitation of novel protected scope.
It is heat exchanger of the present utility model as shown in Figure 1, heat exchanger includes the heat current machine 2 of cold flow device 1 and at least two, at this
The quantity of heat current machine 2 shown in the accompanying drawing of embodiment is three.Cold flow device 1 is flat fin with heat current machine 2, flat
Fin is circular square or other regular shape, and the flat fin shown in the accompanying drawing of the present embodiment is circle
Fin.Flat fin rotates to form spiral radiator structure along its axis, and cold flow device 1 has phase with heat current machine 2
With spiral section and lead angle, cold flow device 1 and heat current machine 2 intersect arranging contact, i.e. the insertion cold flow of heat current machine 2 device 1
Lead angle in, and in the lead angle of the insertion heat current machine 2 of cold flow device 1 similarly, and the length of cold flow device 1 is more than or waits
In the total length of heat current machine 2.
It should be noted that the flow direction of cold medium and the stream of thermal medium in heat current machine 2 in cold flow device 1 in the utility model
To on the contrary, as illustrated by the arrows in fig. 1, the arrow in left side is oriented to the flow direction of the cold medium in cold flow device 1, it is up time
Pin flows, and the arrow on right side is oriented to the flow direction of the thermal medium in heat current machine 2, and it is counterclockwise flow.Need into one
Step explanation, because heat current machine employs at least two scheme in the utility model, the flow direction of heat current machine 2 is preferential
Selection flows to identical.
It need to further illustrate, be carried out by taking a cold flow device 1 and three heat current machines in the utility model accompanying drawing as an example
Illustrate, as depicted in figs. 1 and 2, circulation cold medium 110 in cold flow device 1, cold medium 110 is flowed into from cold import 11, cold outlet 12 is flowed
Go out, the first thermal medium 210 in first heat current machine 2 is flowed into from the first hot import 21, the first heat outlet 22 is flowed out, second heat
Second thermal medium 220 of stream device 2 is flowed into from the second hot import 23, the second heat outlet 24 is flowed out, the 3rd heat of the 3rd heat current machine 2
Medium 230 is flowed into from the 3rd hot import 25, the 3rd heat outlet 26 is flowed out, in the cold medium 110 and heat current machine 2 in cold flow device 1
Thermal medium carries out heat exchange, and specific exchange process is:Cold medium 110 is exchanged heat with the first thermal medium 210 first, 2 kinds of media
Flow direction changes one recuperated cycle of completion after 360 °, when after some recuperated cycles, the first thermal medium 210 completes to change
Heat exchanger is exported after heat;Cold medium 110 continues to be exchanged heat with the second thermal medium 220, when after some recuperated cycles, and second
Thermal medium 220 exports heat exchanger after completing heat exchange;Cold medium 110 continues to exchange heat with the 3rd thermal medium 230, when by some heat exchange
After circulation, the 3rd thermal medium 230 completes to export heat exchanger after heat exchange, and cold medium 110 completes heat exchange export heat exchanger, whole heat exchange
Process terminates.Need furtherly, the thermal medium in three heat current machines 2 can be mutually synthermal or not equality of temperature
Degree.Then it is to carry out the exchange of heat to greatest extent according to mutually synthermal thermal medium;But use step temperature
