Description
The present invention relates to a storage heater, particularly a latent heat is stored up device, it has a heat-proof device, at least one inlet, outlet and collecting chamber that is used for the heat-carrying medium, the latter is connected with the storage heater core fluid that is surrounded by shell, flow path (pipe) is set in core and has space between the flow path, the phase inversion material is arranged in described space.
For example from WO89/09376, known this storage heater from a series of files.This known storage heater has inlet collecting chamber and outlet collecting chamber, and flow path (single flat tube) is connected with these collecting chambers.Indicated as the Fig. 5 from described file, described collecting chamber occupies sizable space.
According to the desired heat energy of reservoir consumption better that passes through, viewpoint with conserve energy, the problem of repeatedly having mentioned is emphasized more and more consumingly, Here it is, the operational structure space that is used for storage heater is more and more littler, but storage heater is required have same even higher thermal capacity simultaneously again, so industrial quarters faces the challenge that continues to increase.At the structure space of motor vehicles, by the storage heater that DE 19530378 C1 know contribution has been done in the solution of this problem, but it not a latent heat storage or saving device, but a hot water storage or saving device.Shown in this file, its space is not only on the volume and has been diminished, but also is divided into a lot of troubles, thus, almost we can say to make structure space not have (expansion) attraction fully.
According to this restricted viewpoint, the latent heat storage or saving device of knowing from the file of mentioning at first is because the space that its chamber of being collected occupies, even the reason therefore on the manufacturing technology also no longer can be thought specially suitable.For example, this frame mode has and manyly usually occurs that dangerous solderings connect and many manufacture process is produced dysgenic particular, and in the flowing space with wherein be equipped with between the space of phase inversion material the improved proportionate relationship of needs is arranged.
Also recommended a kind of heat exchanger (DE 2942147A1), it has the flow path by meander shape trend.Though this heat exchanger has the storage or saving performance, and inapplicable, and because the phase inversion material is placed in the housing, feasible manufacturing upward spends very high and power also is disadvantageous.Flow path is made up of two flats separately, and they are stitched together, and forms flow path by expanding betwixt.Plate between the flow path has reduced the space that is used for the phase inversion material and has therefore caused the storage or saving capacity to reduce.The latent heat storage or saving device of knowing from DE 3227322A1 is made up of stacked module up and down, and surrounds with a heat-proof device.In inside with the module of a shell seal, the hollow body by the spirality trend is set, the latter is communicated with in the center.In the inside of shell one space is arranged, latent heat storage or saving agent can be expanded when fusing therein.Described latent heat storage or saving device is to be provided with for the storage or saving case that is installed in the building, at this moment, it is not suitable for the occasion of using the storage or saving device with big loading power and unloading power in narrow space, but should accomplish latent heat of fusion storage or saving agent as far as possible fully, thus, the circulation of costliness and complicated hollow body and the adjusting (device) of heat-carrying medium are set.
Purpose of the present invention is to make under the storage heater described in the preface is keeping the situation of high storage or saving capacity, high loading power and unloading power and economic manufacturing expense to match with structure space bending with little better.According to the solution of the present invention by drawing in claims.Claim regulation is passed the storage heater core to flow path waveform ground or spirality, in flow path and/or the geometry of the wave height between a plurality of flow path and/or wavelength or spiral can all be irregular.Flow path is flat tube preferably, and it can for example have plug-in part.But, particularly advantageously be, when flat tube as used when being so-called multi-lumen tube in condenser or evaporimeter, be more favourable.This pipe is easy to make by shape separately, and can not fracture when bending, and needed turbulent flow of heat-carrying medium and bigger heat exchange area are provided in flat tube.
The ripple of flow path or the geometry of screw thread can be irregular.The place of the wave height change of flow path just diminishes or becomes the big place or the irregular place of geometry of spiral, and just the shell of storage heater and whole storage heater is correspondingly inhaled the place of disturbing or enlarging.In such a way, storage heater can be advantageously matches with the structure space of bending, and can not cause very high manufacturing expense, because being used for the manufacturing technology of this waveform or helical flow paths is ready-made in the manufacturing of hot swapping, and irregular wave height only is the problem that a machine is adjusted.Compare with the prior art level that single flat tube is set, it must be cut into different length, and under the condition of complexity, insert in the pipe hole at the end and connection.This point is a more expensive generally.According to frame mode of the present invention, usually only enter the storage heater core and need the little space that marks as collecting chamber again from this place of coming out at flow path.All be used as the space of placement phase inversion material between the ripple of flow path or the space between the spiral and around the space of flow path, thus, the ratio of bulk changes over and helps the bigger space that is used for the phase inversion material.This is expection just, even under the little situation of the physical dimension of storage heater, also has same big storage or saving capacity at least, has so just satisfied requirement in best mode.
The above-mentioned space that is used for the phase inversion material almost all encases with corrugated sheet.In the scope of flow path bending, also this plate can be set.Because the phase inversion material is bad heat conductor, so it is not easy to melt fully, thus, is not easy always to reach the heat storage capacity of its maximum, so the space is surrounded as far as possible with corrugated sheet, just can hold the storage capacity to raising and make major contribution.In addition, plate plays the contribution of can not ignore to the stability of storage heater.
The major advantage of storage heater of the present invention is, can stand the variations in temperature of carrying out simultaneously better with the tensile load and the compressive load of pipe, this be because, waveform or spiral flow path are long thereby submissiveer, because being a side, it clamps simultaneously, and in the prior art level, it is to clamp in relative both sides at pipe at the end.Compare with the prior art level, flow path is wanted much less with the load that the metal of storage heater core is connected, thereby the dangerous of fracture obviously descends.Therefore, by can draw, storage heater of the present invention has higher fatigue strength, this is with less to connect the inefficacy that fracture causes by soldering relevant.Other may be that important characteristic and favourable effect can obtain from the following description of embodiment, and these embodiment provide in the accompanying drawings.But the present invention is not limited to these embodiment, because they only are used for better understanding also as the help that designs.

Latent heat storage or saving device 1 is specifically designed in the engine room that is installed in motor vehicles.In this embodiment, the cooling water of engine is the heat-carrying medium, and it sends into the loop (not shown) with cooling water pump, and in the loop, latent heat storage or saving device 1 links together with its inlet 2 and outlet 3.Heat-proof device 4 can be a kind of device of vacuum heat-insulation efficiently, and it can make phase inversion material fusing and that absorb heat at this moment through about 50 hours, even under the condition in winter, also can remain in this accumulation of heat state.If engine start, then cooling water pump is carried cold cooling water, makes it store up the flow path 5 of the storage heater core 6 of device through being arranged in latent heat.At this moment, cooling water and phase inversion material carry out heat exchange, and wherein, the latter begins crystallization and its heat of storing up is passed to cooling water.The cooling water of this rapid heating shorten engine the startup stage, thereby reduced fuel consumption, and also can be used for warm passenger car in addition.In the duty of proceeding, the cooling water of heat gives the phase inversion material with its heat, and thus, latter's refuse is also stored up heat at this moment.This switching motion constantly repeats, thereby whole storage heater, and flow path 5 and the connection thereof that is formed by flat multi-lumen tube 7 especially herein is subjected to great load.But because flow path 5 is long and submissiveer, and corrugated sheet 8 is very not bold, so the very big part of thermal stress is cancelled.Usually can eliminate the fracture that soldering connects or welds.
Tube inlet 2 does not still export 3, all be transferred to the pipe of making the thermal siphon shape separately, the latter is placed on the inside of heat-proof device 4, thus, in inactive state, so form a cooling liquid layer at tube interior, so that high-temperature cooling water is stayed the top or the inside of heat-proof device owing to its density is little, and do not mix with cooling water in the pipe of the outside of heat-proof device 4, the latter is colder and bigger density arranged.The pipe end of arranging down from the arch of thermal siphon is a collecting chamber 12, and wherein, in the embodiment according to Fig. 1, these pipe ends are connected with the pipe end of four flow paths and are connected at this place, to this, do not plan to go through herein.When these pipe ends and collecting chamber 12 connections, they pass the housing 11 of storage heater core 6.
Fig. 2 and 3 difference are that their corrugated sheet 8 has different layouts with collecting chamber 12.In addition, the insulated space 4 that the storage heater of Fig. 2 shows the shell 14 of storage heater 1 and forms between the housing 11 of shell 14 and storage heater core 6 is provided with the support of making of non-Heat Conduction Material 13 in the latter.Insulated space 4 is vacuum heat-insulation devices, supports 13 and then is used to make inner casing 11 not contact with shell 14, so that heat-blocking action is remained on the high level.The thickness of heat-proof device 4 has only several millimeters, helps to make the appearance and size of latent heat storage or saving device 1 for minimum thus.Adopted long corrugated sheet 8 in Fig. 3, so that the number of member is minimum, this corrugated sheet is placed around the sweep of flow path 5.In contrast, can in Fig. 2, find out, between each ripple 10 of flow path 5, place single corrugated sheet 8.In order further to make storage heater 1 be of a size of minimum, 12 of the collecting chambers of Fig. 3 are made half hull shape.The thermal siphon inlet 2 and the outlet 3 that are attached thereto reach in the figure of back all not shown herein.
Fig. 4 and 6 shows by the trapezoidal cross section of being roughly of a storage heater 1, and wherein, Fig. 4 has the necking down of predesignating 15, because structure space has this requirement.The irregular therewith shape of the ripple 10 of flow path 5 matches, promptly by its contour shape that matches with necking down 15.Therefore, almost can be simply and as far as possible all together with flow path 5 and space 9, this (representing as irregular shape) shape of storage heater 1 or storage heater core 6 is used for the phase inversion material.A kind of favourable modification can draw from Fig. 6, and it is that collecting chamber 12 is arranged in the storage heater core 6.Adopt this mode, the inner space that is not particularly suitable for encasing with corrugated sheet 8 of storage heater core 6 can be used as collecting chamber 12 on the one hand, can further reduce unshowned insulated space 4 herein on the other hand.
Fig. 5 is the schematic view according to the arrow A of Fig. 4 of storage heater 1.But collecting chamber 12 is cut open, so that can see the multi-lumen tube of connecting with collecting chamber 12 7.Multi-lumen tube 7 forms the flow path 5 of waveform, and corrugated sheet 8 is arranged betwixt.Fig. 5 shows that corrugated sheet 8 has a large diameter width greater than multi-lumen tube 7.Thus, corrugated sheet 8 has a ledge 16 that exceeds multi-lumen tube 7 or flow path 5, so just can be used in the space 9 of phase inversion material and the space between the single flow path 5 and encase with corrugated sheet 8.Corrugated sheet 8 regularly soldering on flow path 5, and be positioned at the outside plate 8 also regularly soldering on inner casing 11.
Above in Fig. 5, drawn the joint and the flow arrow that are used for thermal siphon, the latter indicates, and cooling water 2 enters and flows out from exporting 3 again from entering the mouth.
Fig. 7, the special mode of 8 and 9 usefulness show about the various possibilities of the configuration of storage heater 1 and the structure that matches with shape separately flow path 5, and this flow path is also done shaping wave in this embodiment.Fig. 7 shows that the ripple 10 of single flow path 5 has diverse wave height, so that match with the shape of the storage heater 1 with necking down 15 and bulging part 17.Shown Fig. 9 of section B by Fig. 7 illustrates that clearly its configuration is all made variable in all three-dimensionals.Also adopted multi-lumen tube 7 herein, so that form flow path 5.Flow path 5 is arranged parallel to each other substantially.Collecting chamber 12 is not shown at this.
Figure 10 and 11 schematic diagram have illustrated the storage heater 1 with helical flow paths 5.The layout of corrugated sheet 8 is only found out in Figure 10.As shown in the figure, corrugated sheet is between spiral 18, and also between external spiral 18 and housing 11, back one situation is not shown.A collecting chamber 12 is positioned at the center of storage heater 1, and another collecting chamber 12 then is arranged on the periphery of storage heater core 6.Wherein, the layout of collecting chamber 12 can be made variable equally.Therefore, another unshowned embodiment has two collecting chambers 12 on the periphery of storage heater core 6, even flow path 5 is done spirality ground by 6 guiding of storage heater core (referring to the Fig. 3 among the DE 4141556 for example).
Can be clear that from Figure 11 flow path 5 also can be made variable with regard to its height H, h, so that satisfy requirement thus to the various configurations of storage heater 1.The also the most handy multi-lumen tube 7 of their flow path 5 is made.Herein, the geometry of the spiral 18 between the flow path 5 is made different, but is identical in the inside of flow path 5 still, promptly has same curvature.Another not shown embodiment with spiral flow path 5 can for example copy Fig. 4 also so to constitute, and promptly in the inside of flow path 5 shape of spiral 18 is made to have different curvature, so that match with necking down 15.
