Existing energy storage equipment has the outer accumulation of energy of pipe, the interior accumulation of energy of pipe, container accumulation of energy etc., and these energy storage equipments, in accumulation of energy process, carry out the increase of heat exchange thermal resistance, reduction of heat exchange efficiency, accumulation of energy time lengthening along with energy-accumulation material phase transition process.
Summary of the invention
The technical problem to be solved in the present invention is to improve the heat exchange efficiency of energy storage equipment, reduces the accumulation of energy time.
In order to achieve the above object, technical scheme of the present invention has been to provide a kind of phase change energy storage apparatus of combination plate type heat exchanger, comprise two clamping plates, by polylith accumulation of energy plate level be superimposed as and accumulation of energy plate row be clamped between two clamping plates, on a clamping plate, be communicated with inlet and liquid outlet, it is characterized in that: every accumulation of energy plate is formed by two heat exchange plate solderings, between two heat exchange plates, be filled with phase-change material, on every heat exchange plate, have a row folding angle α and be the herringbone grooves of 150 °～165 °, the width of everyone font groove is 6～10mm, the degree of depth is 3～5mm, the spacing of adjacent two herringbone grooves is 6～10mm, after the stack of polylith accumulation of energy plate level, form hot switching path by herringbone grooves, refrigerant or heating agent go out from liquid outlet after being entered by inlet after hot switching path.
Preferably, described accumulation of energy plate row be fixed between two clamping plates by the top guide bar and the lower guide rod that run through wherein, is also provided with for by the tight fishbolt of described accumulation of energy plate row pressure between two clamping plates.
Preferably, apply insulation material in the outside by described clamping plate.
Beneficial effect of the present invention: compared with installing with accumulation of energy in the outer accumulation of energy of existing pipe, pipe, container type accumulation of energy etc., it is strong that plate type heat exchanger phase change energy storage apparatus of the present invention has heat-transfer capability, the large (3000-6000W/ (m of the coefficient of heat transfer
2.K)), it is short that cold-storage is released cool time, and power is large, and volume is little, heat exchange efficiency advantages of higher; Simultaneously because the No. of plates of plate type heat exchanger phase change energy storage apparatus can increase as required or reduce, so apparatus structure is easy and energy-conservation.
Brief description of the drawings
Fig. 1 is the phase change cold-storage apparatus structure schematic diagram of a kind of combination plate type heat exchanger of the present invention;
Fig. 2 is the structural representation of accumulation of energy plate;
Fig. 3 is the structural representation of heat exchange plate.
Detailed description of the invention
For the present invention is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
As shown in Figure 1, the phase change energy storage apparatus of a kind of combination plate type heat exchanger provided by the invention, comprise fixed clamping plate 1 and active clamped plate 2, by polylith accumulation of energy plate 6 levels be superimposed as and accumulation of energy plate row be fixed between fixed clamping plate 1 and active clamped plate 2 by top guide bar 3 and lower guide rod 4, and by fishbolt 5 by tight the row pressure of accumulation of energy plate, top guide bar 3, lower guide rod 4, fixed clamping plate 1, active clamped plate 2 and fishbolt 5 are stainless steel material.Insulation material (as aluminium silicate composite) is applied in outside at plate type heat exchanger phase change energy storage apparatus, heat exchange occurs hardly to ensure heat exchange efficiency with the external world.
In conjunction with Fig. 2, every accumulation of energy plate 6 is formed by two heat exchange plate 8 solderings, fills phase-change material 7 therebetween.Phase-change material 7 can inorganic salts, organic matter etc., as the eutectic salts of hexadecane, n-tetradecane, sodium fluoride and water, hydration calcium chloride, Na
2hPO
4, paraffin etc.
In conjunction with Fig. 3, on every heat exchange plate 8, have a row folding angle α and be the herringbone grooves 12 of 150 °～165 °, the angle of tradition herringbone grooves 12 is 120 ° of left and right, and it is that object is not only broken fluid flow boundary layer and reduce flow resistance the heat exchange thermal resistance that more importantly reduces accumulation of energy plate 6 phase change material inside 7 that the present invention adopts the object of 150 °～165 °.The width of everyone font groove 12 is 6～10mm, and the degree of depth is 3～5mm, and the spacing of adjacent two herringbone grooves 12 is 6～10mm, its objective is the heat exchange efficiency of reinforced transformation material 7.After the 6 level stacks of polylith accumulation of energy plate, form hot switching path 9 by herringbone grooves 12, refrigerant or heating agent go out from liquid outlet 10 after being entered by inlet 11 after hot switching path 9.
