Embodiment 1
As shown in figs. 1 and 3, the thermal storage unit that the utility model embodiment provides, including accumulation of heat component, the accumulation of heat component
With the pit 2 and protrusion 1 for being provided with multiple spherical cambered surface types on the face of media contact.
Specifically, in the application of practical rotary regenerative air preheater, accumulation of heat component is usually that the cooperation of positioning plate 10 stores
The form of thermal element 20.Specifically, positioning plate 10 includes flat plate section 102 and is connected to 102 both ends of flat plate section and is put down with described
The side plate bending 101 of 102 integral structure of plate section;Heat accumulating element 20 is plate, is arranged above and below positioning plate 10, and
Pass through the support of side plate bending 101 at 10 both ends of positioning plate.That is, branch of the side plate bending 101 of positioning plate 10 as heat accumulating element 20
Lap position is supportted, simultaneously because there are differences in height between side plate bending 101 and flat plate section 102, to which positioning plate 10 coordinates accumulation of heat member
Part 20 forms the circulation passage of medium.
Such as Fig. 1, schematically indicate in the upper and lower surface of the flat plate section 102 of the positioning plate 10 respectively
The pit and protrusion of multiple spherical cambered surface types are set, can also be respectively provided with as needed on the surface of entire positioning plate and media contact
The pit and protrusion of multiple spherical cambered surface types.Such as Fig. 2, schematically show in the upper surface of plate heat accumulating element 20 under
Surface is respectively arranged with the pit 2 and protrusion 1 of multiple spherical cambered surface types.Under normal circumstances, for best heat transfer effect and anti-product
Grey effect, the surface for being typically employed in positioning plate 10 and heat accumulating element 20 are respectively provided with the pit 2 and protrusion of multiple spherical cambered surface types
1。
The pit 2 and protrusion 1 of multiple ball-types, a side are provided on the surface of its accumulation of heat component of the present embodiment thermal storage unit
Face, 2 position of pit increase the contact area of heat exchange medium, have been correspondingly improved the heat absorption efficiency of heat accumulation plate.On the other hand,
The protrusion 1 of the ball-type on the surface of accumulation of heat component increases the flow-disturbing effect to flow media in channel, can be promoted in channel and be flowed
The heat transfer efficiency of dynamic medium and accumulation of heat component;Simultaneously as protrusion has flow-disturbing effect, the laminar flow layer of medium is reduced, is avoided
There is the problem of dust stratification in accumulation of heat component.
Specifically, realization method as one preferred, as shown in Fig. 1,2 or 3, between 1 alternating of the pit 2 and protrusion
Every can be arranged;Optional simultaneously, the pit 2 and protrusion 1 and the plate face intersection of tablet is circle, the pit 2 with
It is tangent setting between its adjacent protrusion 1, described raised 1 pit 2 adjacent thereto is also tangent setting, that is, each recessed
The plate face circle that hole 2 convexes to form is tangent with six circles of surrounding.
It can also use simultaneously, 2 arrangement in a row of the pit, raised 1 arrangement in a row, and pit row and raised row are handed over
For spaced mode.At this point, being also tangent setting between pit raised or adjacent pit adjacent thereto.
By the way of tangent setting, the area of the plate face of positioning plate and/or heat accumulating element can be utilized to the greatest extent
Concaveconvex structure is formed, namely forms the design shape of similar golf ball surface.Many small ruts of golf ball surface, make
Obtaining golf can have good air dynamic behaviour, dent promote the generation of Transitional And Turbulent Flow, turbulence edge during exercise
Interlayer is not susceptible to flow separation phenomenon, reduces the slough of sphere behind, and smaller air drag makes golf fly more
Far.So the thermal storage unit of the present embodiment uses the design of similar golf table second that can reduce resistance of medium, with higher
While exchanging heat, be not easy dust stratification, the generation of the existing larger problem of corrugated board structures resistance is also avoided.
As a preferred embodiment, multiple pit shapes, size are consistent, shape, the size one of multiple protrusions
It causes.In order to which identical pit and protrusion may be used in easy to process and medium flow stability.Meanwhile positioning plate or storage
The pit and protrusion of two apparent surfaces of thermal element is correspondingly arranged, and can pass through the one side in positioning plate or heat accumulation plate in this way
Pit is suppressed, the other side is also formed protrusion accordingly;Process is not only facilitated, while can also be in existing tabula rasa
It is directly process on the positioning plate and heat accumulating element of type.
Preferably, the type pit that spherical diameter is 4mm, the spherical cambered surface that depth is 0.4mm can be used in practical applications
2, the spherical diameter of corresponding protrusion 1 is also 4mm, is highly 0.4mm.
The pit 2 and protrusion 1 of the size for the circle that a diameter of 3.2mm is formed with tablet intersection can also be used.
The pit 2 and protrusion 1 of above two size, the heat exchange enhancing effect that can be optimal in practical applications is simultaneously
With preferable flow-disturbing effect and accumulatingdust effect.Certainly, specific size design personnel still can according to actual needs into
Row selection processing.
In conclusion the positioning plate of the present embodiment thermal storage unit and/or the surface portion of heat accumulating element pass through pressing mode
Form the protrusion and pit of spherical cambered surface, similar golf spherical surface, the positioning plate and heat accumulating element of the air preheater thermal storage unit
In the case where not changing plate thickness so that the contact area of air-flow and plate face increases, while enhancing the disturbance of air-flow, has certainly
The effect of body deashing, alleviates dust stratification.
