It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, is explicitly described the technical scheme in the embodiment of the utility model, it is clear that described reality
Applying example is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, ability
It is practical new to belong to this for domain those of ordinary skill every other embodiment obtained without making creative work
The range of type protection.
Regenerator has use in various kinds of equipment, to be used to improve the thermal efficiency of equipment complete machine.Common regenerator core
Body is usually plate-fin, and plate-fin recuperator core is usually made of partition, fin, strip of paper used for sealing, flow deflector.In adjacent two partition room
It places fin, flow deflector and strip of paper used for sealing and forms an interlayer, referred to as channel, such interlayer is stacked according to the different modes of fluid
Get up, is brazed into a single piece just composition plate beam.Due to common fin structure be section it is usually rectangular, cold fluid and hot fluid it
Between heat exchange area it is smaller, cause heat exchange efficiency lower.
Based on this, referring to Fig. 1 and Fig. 2, the utility model embodiment provides a kind of regenerator core, comprising: is stacked
Multiple fins, each fin includes the inner space being formed by sheet metal, inner space include it is multiple be arranged in the vertical direction it is interior
Portion subspace, each internal subspace form first runner 8；Exterior space is formed between the sheet metal of two fins, it is external empty
Between include multiple external subspaces being arranged in the vertical direction, each external subspace formation second flow channel 9；First runner 8 and second
The transversal cross-section of runner 9 is special-shaped polygon.
Wherein, each fin is plate structure, is stacked and refers to that the lower planes of plate structure are connected with each other.Specifically

Pipe-like, internal subspace are respectively equipped with opening at longitudinal both ends, using as fluid inlet and fluid outlet.First runner 8
Between be disconnected, the first fluid so that each first runner 8 can circulate respectively.Preferably, between first runner 8
It can be and be parallel to each other, the utility model embodiment is not construed as limiting this.
Since multiple fins are stacked, also, the shape of the first runner 8 due to including in each fin is logical
The special-shaped polygon for crossing sheet metal formation therefore necessarily cannot be complete when being stacked between the sheet metal of two adjacent fins
It is complete to coincide, to be capable of forming external subspace between the sheet metal of two fins, second flow channel 9 can be formed.Due to second
Runner 9 is located between two fins, namely between the first runner 8 of upper layer fin and the first runner 8 of lower layer's fin, and
Alternating floor sheet metal between second flow channel 9 and first runner 8, therefore, when first runner 8 is passed through first fluid, second flow channel 9
When being passed through second fluid, in the process of circulation of fluid, it can be realized and change between temperature different first fluid and second fluid
Heat.It should be noted that above-mentioned longitudinal direction is the flow direction of fluid in runner, and laterally it is the cross-wise direction of runner.
Regenerator core provided by the embodiment of the utility model, comprising: the multiple fins being stacked, each fin include
The inner space being formed by sheet metal, inner space include multiple inside subspaces being arranged in the vertical direction, each internal subspace
Form first runner；Form exterior space between the sheet metal of two fins, exterior space include it is multiple be arranged in the vertical direction it is outer
Portion subspace, each external subspace form second flow channel；The transversal cross-section of first runner and second flow channel is special-shaped polygon.
Since the transversal cross-section of first runner and second flow channel is special-shaped polygon, contact area is relatively large, and heat exchange efficiency is higher；
Also, phase alternating floor sheet metal, heat exchange rate are higher between first runner and second flow channel.
