Abstract
The invention discloses a kind of multipaths plate fin type radiator, include the heat-sink unit of some quadrangles arranged step by step, it is respectively arranged with the adjacent both sides in heat-sink unit side of bottommost on outlet of hot side and cold side import, a heat-sink unit of top and the outlet of hot side and cold import and outlet of cold side when import relative position is respectively arranged with hot.Heat, the cold fluid of the present invention have remained the heat exchange form of reverse flow in whole flow process, each heat-sink unit is had the heat exchange amount of maximum, effectively increase radiating efficiency.
Description
Technical field
The present invention relates to a kind of multipaths plate fin type radiator, belong to military aircraft air conditioner heat radiator field.
Background technology
Multipaths plate fin type radiator is one kind of plate fin type radiator, be in order to improve radiating efficiency and by hot and cold side
Flowing of the fluid in radiating core is respectively divided into n flow, cold and hot fluid is respectively carried out n flowing of turning back wherein and goes forward side by side
Row heat exchange, the multipaths plate fin type radiator of prior art its structure is as shown in Figure 1-2：Cold and hot fluid is respectively divided into n stream
It is level-crossing structure between journey, flow, radiating core is divided into n by the flowage structurenIndividual heat-sink unit, cold and hot fluid is every
Heat exchange is carried out in individual heat-sink unit.
Its operation principle is as follows：The hot hot fluid in import in the 1st heat-sink unit by it is cold while pass through (n-1)th radiating
The cold fluid of unit carries out the 1st cooling, subsequently into the 2nd heat-sink unit by cold flow of the cold side by n-th of heat-sink unit
Body carries out the 2nd cooling, enters back into the 3rd heat-sink unit and carries out the 3rd by the cold fluid of the 3n-1 heat-sink unit by cold side
Secondary cooling, is carried out successively, until to n-thnIndividual heat-sink unit, the fluid of outlet of hot side carries out last 1 by the fluid of cold side import
Secondary cooling.
The structure of above multipaths plate fin type radiator is that current military aircraft multipaths plate fin type radiator is generally used
Typical structure, due to being limited by flow arrangement, hot fluid is from the 1st heat-sink unit to n-thnIndividual heat-sink unit stream
In dynamic process, the cold fluid, the cold fluid of n heat-sink unit, 3n-1 radiating that n-1 heat-sink unit has been flowed through respectively are single
The cold fluid of member, the cold fluid of 4n-1 heat-sink unit are cooled down up to cold side import cold fluid, in hot fluid along each radiating
During unit flows, the cold fluid for flowing through different units jumped respectively is cooled down, in some heat-sink units, can be gone out
The co-current flow situation cooled down again by high temperature cold fluid, or even the hot and cold stream of some heat-sink units are now first cooled down by low temperature cold fluid
Body temperature difference very little, substantially without heat exchange, case above reduces the heat exchange efficiency of product, adds the unnecessary weight of product
Amount and volume.
The content of the invention
The present invention is intended to provide a kind of multipaths plate fin type radiator, with solve existing multipaths plate fin type radiator due to
The cold and hot fluid temperature difference caused by structure design is unreasonable is small, the problems such as heat exchange efficiency is low, volume and weight is big.
The present invention is achieved by following technical solution：
A kind of multipaths plate fin type radiator, includes the heat-sink unit of some quadrangles arranged step by step, the one of bottommost
Be respectively arranged with the adjacent both sides in individual heat-sink unit side on outlet of hot side and cold side import, a heat-sink unit of top with
The outlet of hot side and cold import and outlet of cold side when import relative position is respectively arranged with hot.
The outlet of hot side and the axis of cold side import are mutually perpendicular to.
The axis of the hot side import and outlet of cold side is mutually perpendicular to.
The beneficial effects of the invention are as follows：
Compared with prior art, the multipaths plate fin type radiator that the present invention is provided, employs the design knot of space distributary
Structure, hot fluid has been flowed through n-1 radiating single respectively during from the 1st heat-sink unit to n-th of heat-sink unit flowing
The cold fluid of member, the cold fluid of n-2 heat-sink unit, the cold fluid of n-3 heat-sink unit, the cold fluid of n-4 heat-sink unit
Until cold side import cold fluid is cooled down, heat, cold fluid have remained the heat exchange of reverse flow in whole flow process
Form, makes each heat-sink unit have the heat exchange amount of maximum, under equal working condition, radiating efficiency can improve 10%.

In figure：The heat-sink units of 1- first, the heat-sink units of 2- second, 3- heat-sink units, the hot side imports of 4-, 5- outlet of hot side,
The cold side imports of 6-, 7- outlet of cold side.
Embodiment
Technical scheme is described further below in conjunction with accompanying drawing, but required protection domain does not limit to
In described；
As in Figure 3-5, the multipaths plate fin type radiator that the present invention is provided, including some quadrangles arranged step by step
Outlet of hot side 5 and cold side import 6 are respectively arranged with heat-sink unit 3, the adjacent both sides in the side of a heat-sink unit 3 of bottommost,
With the outlet of hot side 5 and the cold import 4 when the relative position of import 6 is respectively arranged with hot on one heat-sink unit 3 of top
With outlet of cold side 7, the axis of outlet of hot side 5 and cold side import 6 is mutually perpendicular to, and the axis of hot side import 4 and outlet of cold side 7 is mutual
Vertically.The import and export mouth of pipe of cold and hot fluid be arranged in radiator be mutually perpendicular to intersect both direction on, one from it is lower to
On realize multipaths structure, one is realized multipaths structure from top to bottom, its mutual liquid form be space distributary mode.
Radiating core is equally divided into n part from top to bottom, forms n heat-sink unit 1.
Its operation principle is as follows：The hot fluid of hot side import 4 is introduced into the 1st heat-sink unit 3 by stream by n-1 radiating
The cold fluid of unit 3 carries out the cooling of the 1st flow, subsequently into the 2nd heat-sink unit 3 by stream n-2 heat-sink unit 3 of process
Cold fluid carries out the cooling of the 2nd flow, enters back into the 3rd heat-sink unit 3 and is entered by stream by the cold fluid of n-3 heat-sink unit 3
The cooling of the flow of row the 3rd, until finally enter n-th of heat-sink unit 3 is carried out the n-th flow from the cold fluid of cold side import 6
Cooling.
The multipaths plate fin type radiator design structure multipaths plate fin type radiator design structure more of the prior art
Space distributary flowing is changed into from original plane distributary flowing compared to the mutual liquid form due to cold and hot fluid so that hot-fluid
Body is during from the 1st heat-sink unit to n-th of heat-sink unit flowing, all the time by the cold fluid with its reverse flow successively
Cooled down, each heat-sink unit has the heat exchange amount of maximum, greatly improves the radiating efficiency of product.
