Description
Technical field
A kind of brick is the utility model is related to, especially a kind of electrical heating storage for improving rate of heat exchange, increasing the service life
Can equipment energy storage brick.
Background technology
Because electric industry mechanism using the electricity price of valley electricity to giving preferential treatment, therefore, generate in succession it is many will be low
Paddy electricity can change into the device that thermal energy storage gets up, and heat storage electric boiler is exactly one of which.The structure of heat storage electric boiler is
It is provided with the boiler shell of an insulation by refractory block（Gitter brick）The regenerative apparatus built by laying bricks or stones, regenerative apparatus and housing
Side form wide air inlet duct and exhaust passage, have multiple horizontal and vertical perforated holes in regenerative apparatus, longitudinally through
Hole is ventilating duct, extends transversely through the heating wire for being provided with hole and connecting with power supply, and its heating wire is embedded in form the resistance to of air channel
In groove in fiery building block, while provided with the time controller and temperature controller of control power supply.It is additionally provided with housing mutually
The heat-exchanger rig and circulating fan of connection, the outlet of circulating fan connect with air inlet duct, and exhaust passage connects with heat-exchanger rig.Work
Principle is：When electric energy is at a low ebb, startup power supply, heating wire is worked, and caused heat energy is stored by refractory block, works as temperature
Degree, time power off when reaching setting value；And when electric energy is in peak and needs heat, start circulating fan, blower fan output
Air absorbs the heat of refractory block storage and heats up to form hot blast, hot blast is situated between by heat exchanger and heat-carrying by ventilating duct
Circulating fan is returned to after mass transter, is circulated again.Existing energy storage brick is that brick body is made with refractory materials such as magnesia, in brick body
There are a multiple transverse grooves and multiple cannelures in top and bottom respectively, and the cross section of transverse groove and cannelure is semicircle, and brick body is built by laying bricks or stones
Relative with transverse groove into transverse groove during regenerative apparatus, cannelure is relative with cannelure, so as to form multiple horizontal and vertical run through
Circular opening.Because circulating fan outlet is smaller, and air inlet duct is wide and the section of regenerative apparatus is larger so that regenerative apparatus
Blast is irregular suffered by sectional area, and multiple ventilating ducts can make to cause accumulation of heat by the air quantity difference of each ventilating duct in the unit interval
The excessive temperature differentials of different parts in device, not only reduces the heat exchange efficiency of equipment, but also shortens the service life of equipment.
The content of the invention
The utility model is to solve the above-mentioned technical problem present in prior art, there is provided one kind can improve heat exchange
Rate, the electrical heating energy storage device energy storage brick to increase the service life.
Technical solution of the present utility model is：A kind of electrical heating energy storage device energy storage brick, has brick body, in brick body
There is transverse groove in face, has cannelure below brick body, the cross section of transverse groove is semicircle, and the cannelure is by top surface and two sides
Form.
The cross section of the cannelure is trapezoidal.
The height of brick body is 90mm, length 240mm, width 150mm, the semicircle of the cross section of the transverse groove
Shape radius is 25mm；The trapezoidal bottom of the cannelure cross section is 85mm, and a height of 23mm, the base angle R1 of waist is 78 °.
The transverse groove has chamfering R2 of the radius for 6mm with brick body upper surface joint；The top surface of the cannelure and two
There is the chamfering R3 that radius is 2mm between individual side.
The utility model cannelure is one and is made up of top surface and two sides, is ensureing have between hot blast and energy storage brick
On the premise of larger heat exchange area, reduce the quantity of ventilating duct compared with the prior art, regenerative apparatus sectional area institute wind-engaging can be made
Pressure is uniformly distributed in ventilating duct few in number so that and it is identical by the air quantity of ventilating duct in the unit interval, avoid accumulation of heat from filling
Interior different parts excessive temperature differentials is put, not only increases the heat exchange efficiency of equipment, but also extends the service life of equipment.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is Fig. 1 left view.
Embodiment
Below in conjunction with brief description of the drawings specific embodiment of the present utility model.
As shown in Figure 1, 2：There is the brick body 1 same as the prior art made of the flame-proof thermal insulation materials such as magnesia, in brick
Body 1 has three transverse grooves 2 above, and brick body 1 has cannelure 3 below, and the cross section of transverse groove 2 is semicircle, with prior art institute
The difference is that cannelure 3 is one and is made up of top surface 3-1 and two side 3-2 that is, its cross section can be rectangle or ladder
Shape etc., it is preferred that it is trapezoidal, the stability of whole regenerative apparatus can be improved.Optimal selection of the present utility model is brick body 1
Highly it is 90mm, length 240mm, width 150mm, the semicircle radius of the cross section of transverse groove 2 is 25mm, cannelure 3
Cross section be trapezoidal and trapezoidal bottom is 85mm, a height of 23mm, the base angle R1 of waist is 78 °.In order to ensure the prolonged resistance to of brick body 1
With transverse groove 2 has radius for 6mm chamfering R2 with the upper surface joint of brick body 1, has radius between the top margin and waist of cannelure 3
For 2mm chamfering R3.
