Description

Accumulation of energy brick

Technical field

The utility model belongs to warmer field, for accumulation of energy heat accumulation, mainly refers to a kind of accumulation of energy brick.

Background technology

Along with population increases, the Appropriate application of the energy how is made to become a large problem of social development.Existing energy storage brick is generally planar style module structure, i.e. certain plane of energy storage brick and heating element contact, and this mode contact area is little, and absorb thermal efficiency low, energy storage effect is also poor; Although also have the working face a kind of certain plane of energy storage brick being arranged with zigzag structure, but this zigzag structure by some cross sections tooth bar triangular in shape mutually successively abreast file form, the Linear fluid excessive velocities of its longitudinal direction, heating temperature is than laterally high, brick body is heated inequality, bring adverse effect to life-span and energy storage effect, therefore there is Improvement requirement.

Utility model content

For solving the problems of the technologies described above, the utility model provides a kind of novel energy storage brick, and its heat transfer efficiency is high, disperses with the effect of energy storage better.

The technical solution of the utility model: a kind of accumulation of energy brick, for hexahedron symmetrical structure, it is characterized in that: described hexahedral any plane is provided with indent working face, and described indent working face is convexly equipped with separate and parallel vertical bar, and described vertical bar is provided with groove.Indent working face increases the contact area of accumulation of energy brick and heating element heater, and vertical bar structure is beneficial to air-flow fluid longitudinal flow, and the groove on vertical bar extends the hot-air time of staying.

Preferably, the accumulation of energy brick planes align at described vertical bar upper surface and its place.

Preferably, groove is cylindrical or reverse frustoconic.This structural area is comparatively large, is conducive to heat accumulation and stops.

Preferably, projection is provided with between vertical bar.Projection is set between vertical bar, increases heating surface area, also slow down the velocity of liquid assets of longitudinal air flow fluid.

Preferably, vertical bar selects rectangular structure better.

Preferably, described projection is cylindrical.Circular configuration processing is easy, larger relative to its surface area other shapes, expands the thermocontact area of energy storage brick, extends heat exchanger time.

Preferably, projection distributes from indent working face center to surrounding divergence expression.I.e. indent working face, positive middle part projection is intensive, and centered by middle, the projection to surrounding diffusion reduces gradually.Because origin of heat is in the heating element heater at middle part, therefore there is the conflict of energy storage and heat release (i.e. heat energy release) simultaneously.If heat release is too fast, then energy storage capacity is not enough; If heat release is excessively slow, then heat energy all concentrates on middle part, cannot utilize the energy storage area of monoblock, and then affect the even heat release of energy storage brick.This programme is arranged by the projection of rational position, balances the contradiction between energy storage and heat release, improves the energy storage capacity of energy storage brick, is conducive to the even heat release of energy storage brick simultaneously.

Preferably, described projection and described groove longitudinally, are laterally all being evenly arranged.

Preferably, bump height is less than the height of described vertical bar.Bump height is less than vertical bar height, in space, form local flow, is conducive to the storage of heat.

Preferably, described depth of groove is 1/2 of vertical bar height, and described bump height is 2/3 of described vertical bar height.

Preferably, indent working face accounts for 2/3 of its place area of plane.Such setting increases the contact area of energy storage brick and heating element heater, is beneficial to heat absorption.

Preferably, described indent working face both sides are provided with the passage vertical with vertical bar.Accumulation of energy brick increases heat-conducting area after installing on the one hand, and another side is also convenient to air-flow laterally circulation, and hot gas is evenly dispersed.

Preferably, except other planes out-of-plane at this indent working face place are provided with a heat insulation coating.Heat insulation coating coated brick body, make heat storage inner at brick body, heat only can distribute from the plane at inner concave place; Loss reducing, extends temperature retention time, improves the utilization rate of energy storage brick.

Preferably, in described heat insulation coating, the weight portion composition of component comprises:

Nano ceramic powder 100-500

Yittrium oxide 10-50

Seven oxidation two technetium 10-50

Alumina silicate 100-200

Aluminium oxide 100-200.

Common heat insulation coating cannot meet the demand of energy storage brick, because common heat insulation coating often asks most the highest heat-insulating property, and this programme energy storage brick needs even heat release, keep certain exotherm rate, therefore utility model people have developed a kind of heat insulation coating, can thermal requirements be met, also can meet exotherm rate's requirement.

Preferably, described accumulation of energy brick four end angle place is provided with cavity, is filled with phase-change accumulation energy cladding in described cavity.Accumulation of energy brick itself adopts insulation material manufacture to form, and outside store heat own, the coated physical efficiency of additional phase-change accumulation energy further makes brick body four hold angle to absorb storage power.

The beneficial effects of the utility model: adopt accumulation of energy brick accumulation of heat speed of the present utility model fast, slow down the too fast and heating surface area of the horizontal and vertical air-flow fluid fluid of conventional planar brick body little problem, extend the hot gas time of staying, energy storage better effects if, and heat conduction is more even with heat radiation, this accumulation of energy brick can be effectively applied to equipment or the place that accumulating type electric heater etc. needs energy storage as required, is conducive to economize energy, improves whole society benefit.
