For example, when molten salt is used, the energy storage unit adopts a rigid shell, and the molten salt is encapsulated in the rigid shell and placed in the rigid shell. A groove is formed on the body for embedding the absorption end heat exchange device and the release end heat exchange device.

The use of coils can increase the heat exchange area with the heat storage unit and improve the efficiency of storage or release.
[0101] Further, the first heat exchange coils and the second heat exchange coils are alternately arranged in the energy storage unit.
[0102] When there is only one energy storage stack 100 in the energy storage station 10 of this embodiment, the communication pipeline between the absorption end heat exchange device 101 and the discharge end heat exchange device 102 adopts the aforementioned first to fourth energy storage station 10 The structure is fine.
[0103] When there are multiple energy storage stacks 100 in the energy storage station 10 of this embodiment, the connecting pipelines of the absorption end heat exchange device 101 and the discharge end heat exchange device 102 in each energy storage stack 100 are as follows Figure 3e or Figure 3f The setting method shown.

The liquid inlet pipe (141 or 151) of each discharge end heat exchange device 102 is connected to the main liquid inlet pipe. The liquid outlet pipes (142 or 152) of the heat exchange device 102 at the discharge end are connected to the main liquid outlet pipe.
[0104] Combine Figure 4a to Figure 4f As shown, an intermediate conversion heat exchanger of the present invention, denoted as the intermediate conversion heat exchanger 20, includes: a heat absorption end 201, which is used to connect to the energy storage station 10/temperature regulation equipment (eg, the first temperature regulation equipment 1111 Or the fourth temperature adjustment device 1221); and, the heat release end 202 is used to connect to the temperature adjustment device (eg, the second temperature adjustment device 1121 or the third temperature adjustment device 1211)/energy storage station 10.
[0105] The intermediate conversion heat exchanger 20 in the embodiment of the present invention is connected between the energy storage station 10 and the temperature adjustment device, and plays a role in the transfer of energy between the energy storage station 10 and a plurality of temperature adjustment devices. In practical applications, the number of temperature regulating devices is not fixed, and it can be one, two, or even more; and the energy storage station 10 can also have one or more. Therefore, in the embodiment of the present invention, the heat transfer There are one or more heat-absorbing ends 201 and one or more heat-dissipating ends 202, which can realize multi-channel conversion, multi-channel conversion, or multi-channel conversion, which can facilitate the adjustment of the energy storage station 10 and the adjustment The energy storage and release between the temperature devices (the absorption end temperature adjustment device 1011 or the release end temperature adjustment device 1021), and the path control is convenient, according to the actual situation, some of the paths can be connected for energy exchange. Moreover, the communication pipeline between the energy storage station and the temperature control device can be simplified, the pipeline layout is convenient, and the cost is reduced.
[0106] In the intermediate conversion heat exchanger 20 of the embodiment of the present invention, when the heat absorption end 201 is connected to the energy storage station 10, the heat release end 202 is connected to the temperature adjustment equipment, and the energy storage station 10 supplies heat to the temperature adjustment equipment through the intermediate conversion heat exchanger 20 It may also be that the temperature regulating device supplies cold energy to the energy storage station through the intermediate heat exchanger 20. When the heat-absorbing end 201 is connected to the temperature regulating device, the heat-emitting end 202 is connected to the energy storage station 10, and the temperature regulating device supplies heat to the energy storage station 10. Alternatively, the energy storage station 10 supplies cold energy to the temperature regulating device.
[0107] In the embodiment of the present invention, the heat-absorbing end 201 is used to absorb the heat of the energy storage station 10 (or the first temperature adjustment device 1111), that is, the end of cooling capacity (releasing cooling capacity). Various specific structures are adopted. For example, a fluid medium is used as a carrier, and the heat-absorbing end 201 adopts a heat exchange device and the heat-exchanging device of the heat releasing end 112 on the side of the heat storage station 11 (or the first temperature regulating device 1111) passes through the pipeline. Connected, the fluid medium absorbs heat from the heat storage station 11 side (or the first temperature regulating device 1111), the fluid medium flows to the heat absorption end 201, and the heat absorption end 201 exchanges heat with the medium fluid at the heat release end 202, thereby The heat is transferred to the exothermic end 202. Alternatively, the heat-absorbing end 201 is connected with the heat exchange device of the cold-capacity absorption end 121 (or the fourth temperature adjustment device 1221) of the cold-capacity storage station 12 by a heat exchange device through a pipeline. At this time, the heat-absorption end 201 can understand To release the cold end 201, the fluid medium absorbs heat from the cold storage station 12 side (or the fourth temperature adjustment device 1221) (absorbs heat, that is, releases cold), and the fluid medium flows to the end 201 to absorb heat The end 201 exchanges heat with the medium fluid of the heat-emitting end 202 to transfer heat to the heat-emitting end 202.
[0108] In the same way, the heat release end 202 is used to release heat to the energy storage station 10 (or the second temperature adjustment device 1121), that is, the end that absorbs cold (absorbs cold). Various specific structures are adopted. For example, the fluid medium is used as the carrier, and the heat-exchanging device at the heat-releasing end 202 is used with the heat-exchanging device of the heat-absorbing end 111 on the side of the heat storage station 11 (or the second temperature regulating device 1121) through the pipeline Connected, the fluid medium absorbs heat from the heat storage station 11 side (or the second temperature adjustment device 1121), the fluid medium flows to the heat release end 202, and the heat release end 202 exchanges heat with the medium fluid at the heat absorption end 201, thereby The heat is transferred to the heat sink 201. Alternatively, the heat release end 202 is connected with the heat exchange device of the cold release end 122 (or the third temperature adjustment device 1211) of the cold storage station 12 by a heat exchange device through a pipeline, and the fluid medium is directed to the cold storage station 12 side (Or, the third temperature adjustment device 1211) releases heat (releases heat, that is, absorbs cold energy), the fluid medium flows to the heat release end 202, and the heat release end 202 exchanges heat with the medium fluid at the heat absorption end 201, thereby The heat is transferred to the heat sink 201.
[0109] That is, when the intermediate heat exchanger is applied to the cold energy storage device, the reverse process of the heat transfer in the intermediate heat exchanger 20 is cold energy transfer, that is, heat is absorbed and cold energy is released.
[0110] In an alternative embodiment, the heat-absorbing end 201 specifically adopts a heat exchange device, such as a plate heat exchanger, an evaporator, or a heat exchange coil. The exothermic end 202 specifically adopts a heat exchange device, such as a plate heat exchanger, a condenser, or a heat exchange coil.
[0111] In the intermediate heat exchanger 20 of the embodiment of the present invention, the number of the heat absorption end 201 and the heat release end 202, and the arrangement of the external connection pipeline group of the heat absorption end 201 and the heat release end 202 are based on the connection side (energy The number of connecting pipe groups of the heat exchange device on the storage station side and the temperature control equipment side (see the section on the energy storage device below) can be determined.
[0112] In an optional embodiment, there are one or more heat-absorbing ends 201 of the heat conversion device 20 in the embodiment of the present invention, and the pipes of each heat-absorbing end 201 are independently arranged. For example, the heat sink 201 includes one (such as Figure 4a , Figure 4b with Figure 4f Shown) or more (see Figure 4d The heat release end 202 of the intermediate heat exchanger 20) the third heat exchange device, each third heat exchange device has an inlet pipe 211 and a liquid outlet pipe 212 (ie, a set of connecting pipe sets 21), which pass through two Two pipelines are connected to the heat exchange device on the side of the energy storage station 10 (or the first temperature regulating device 1111 or the fourth temperature regulating device 1221), and the energy storage station 10 (or the first temperature regulating device 1111 or The heat on the side of the fourth temperature regulating device 1221) is transferred to the heat absorbing end 201. That is, each third heat exchange device independently communicates with the energy storage station 10 (or the first temperature adjustment device 1111 or the fourth temperature adjustment device 1221). Another example, such as Figure 4c , Figure 4e As shown, the heat absorption end 201 is a third heat exchange device, and the liquid inlet end of the third heat exchange device is connected to a plurality of liquid inlet pipes 211, and the liquid outlet end is connected to a plurality of liquid outlet pipes 212. A liquid inlet pipe 211 and a liquid outlet pipe 222 are used as a connecting pipeline group 21 to form a plurality of independent connecting pipeline groups, through which the plurality of independent connecting pipeline groups are respectively exchanged with the third heat exchange on the side of the external temperature regulating device The device is connected.
[0113] In another alternative embodiment, there are multiple heat-absorbing ends 201, and the pipes of the multiple heat-absorbing ends 201 are connected to each other. There are many ways to communicate with each other, as long as multiple heat absorption ends can be connected to the energy storage station 10 (or the first temperature regulating device 1111 or the fourth temperature regulating device 1221). For example, such as Figure 4d As shown, a plurality of heat absorption ends 201 are communicated with a liquid inlet transfer pipeline 221 and a liquid outlet transfer pipeline 222. The liquid inlet pipe 211 of each heat absorption end 201 is connected with the liquid inlet transfer pipeline 221, and each heat sink The liquid outlet pipe 212 of the end 201 is in communication with the liquid outlet transfer pipeline 222. Then pass the inlet transfer pipeline 221 and the outlet transfer pipeline 222 as a set of connected pipeline groups, and pass through two pipelines to the energy storage station 10 (or the first temperature regulating device 1111 or the fourth temperature regulating device 1221) The heat exchange device on the side is connected.
[0114] In the same way, when there are one or more radiating ends 202, the pipes of each radiating end 202 are arranged independently, and the setting method is the same as the aforementioned heat absorbing end 201. When there are multiple radiating ends 202, the pipes of the multiple radiating ends 202 are connected to each other, and the connection method is the same as the aforementioned heat absorbing end 201. I will not repeat them here.
[0115] Therefore, in the intermediate heat exchanger of the embodiment of the present invention, there are the following specific embodiments according to the arrangement of the pipes of the heat absorption end 201 and the heat exchange end 202.
[0116] Such as Figure 4a As shown, in the intermediate heat exchanger I, there is one heat-absorbing end 201 with one connecting pipe group; there are multiple heat-releasing ends 202, and the connecting pipe groups of the multiple heat-releasing ends 202 are independently arranged.

[0122] Of course, the structure of the intermediate heat exchanger in the embodiment of the present invention is not limited to the above six types, and the structures of the heat absorption end 201 and the heat release end 202 can be interchanged or combined arbitrarily. The number of connecting pipe groups of the heat exchange device on the connecting side (the energy storage station side and the temperature regulating equipment side) determines the structure of the suitable intermediate heat exchanger. In addition, when there are multiple sets of connecting pipe groups at the heat absorption end 201 (or the heat release end 202) of the intermediate conversion heat exchanger, the number is not limited, and depends on the number of energy storage stations 10 or temperature regulation equipment to be connected. OK.
[0123] In the intermediate heat exchanger 20 of the embodiment of the present invention, the heat exchange device of the heat absorption end 201 and the heat exchange device of the heat release end 202 can be arranged separately, for example, when a plate heat exchanger is used, the two are arranged oppositely (contactable or No contact) to ensure the maximum heat exchange area; when heat exchange coils are used, the coils of the two are arranged alternately (contact or non-contact) to ensure effective heat exchange. Alternatively, the heat exchange device of the heat absorption end 201 and the heat exchange device of the heat release end 202 are designed as a whole. The arrangement method is not limited, as long as it is realized that the heat exchange device at the heat absorption end 201 and the heat exchange device at the heat release end 202 can perform heat transfer. Such as Figure 4a to Figure 4f As shown, both the heat-absorbing end 201 and the heat-dissipating end 202 adopt a non-contact heat exchange device structure. Of course, the heat exchanger in the embodiment of the present invention is not limited to the structure given in the drawings.

The energy storage station 10 can be controlled according to the actual situation. To release energy to part of the temperature regulating equipment, it is also possible to control part of the temperature regulating equipment box energy storage station 10 to store energy.
[0125] Combine Figure 4g with Figure 4h As shown, in the embodiment of the present invention, an intermediate conversion heat exchanger is also provided, and the mixing unit 30 includes: a heat absorption end 301, which is used to connect to the energy storage station 10/temperature regulation equipment (eg, the first temperature regulation equipment 1111 Or the fourth temperature adjustment device 1221); the heat release end 302, used to connect to the temperature adjustment device (eg, the second temperature adjustment device 1121 or the third temperature adjustment device 1211)/energy storage station 10; and, a unidirectional heating device 31. The heat-absorbing end 301 and the heat-dissipating end 302 are arranged at both ends of the unidirectional heat conducting device 31.
[0126] The mixing unit 30 of the embodiment of the present invention can provide precise energy for the temperature regulating device when the energy storage station releases energy to the temperature regulating device at the discharge end by adding the unidirectional heat conducting device 31. In addition, it is also applicable to situations where energy transmission between the energy storage station 10 and the temperature adjustment device (the absorption end temperature adjustment device 1011 or the release end temperature adjustment device 1021) cannot be carried out in a set direction. Generally, heat can only be transferred from the high temperature end to the low temperature end. If the temperature in the heat storage station itself is higher than the temperature of the medium output by the temperature regulating device, at this time, the heat storage station still has a lot of heat supply The storage capacity, at this time, the heat storage station cannot be stored in the set direction, but it will cause the heat loss of the heat storage station, which has the opposite effect. The same problem is encountered when the heat storage station releases heat. Therefore, the embodiment of the present invention provides the mixing unit 30, which uses the unidirectional heat conducting device 31 to measure the temperature of the medium leading from the temperature regulating equipment to the heat (cold) storage station and the temperature of the medium leading from the heat (cold) storage station to the equipment. It is adjusted so that it can provide accurate energy to the temperature regulating device at the release end, or the energy storage station 10 and the temperature regulating device can transfer heat normally in the set direction.
[0127] The mixing unit 30 of the embodiment of the present invention is based on the aforementioned intermediate heat transfer device 20, and a unidirectional heat conducting device 31 is added between the heat absorption end and the heat release end. Therefore, the structure of the absorption end 301 and the heat release end 302 of the mixing unit 30 and their functions are the same as those of the heat absorption end 201 and the heat release end 202 of the intermediate conversion heat exchanger 20. Please refer to the foregoing content. Repeat it again.
[0128] Therefore, based on Figure 4a to Figure 4f In the structure of the intermediate heat transfer device I to the intermediate heat transfer device VI, a one-way heat conducting device 31 is added between the heat absorption end and the heat release end to sequentially obtain the mixing units I to the heat absorption end and the heat release end corresponding to the same Mixing unit Ⅵ. Such as Figure 4g The mixing unit II 30 shown is obtained by adding a unidirectional heat conducting device 31 on the basis of the intermediate transfer heat exchanger II 20, such as Figure 4h The mixing unit VI30 shown is obtained by adding a unidirectional heat conducting device 31 on the basis of the intermediate transfer heat exchanger VI20.
[0129] In the mixing unit 30 of the embodiment of the present invention, the unidirectional heat conducting device 31 realizes (forcibly) exchange of heat from the heat absorption end to the heat release end. Specifically, a refrigerant heat exchanger or a semiconductor temperature regulator can be used.
[0130] In an alternative embodiment, the refrigerant heat exchanger includes an evaporator 311, a compressor (not shown), a condenser 312 and an expansion valve (not shown), and the four are connected to form a heat exchange circuit. The mixing unit 30 includes two heat-absorbing chambers 303 and a heat-releasing chamber 304 that are provided with heat insulation and heat preservation; the evaporator 311 is arranged opposite to the heat-absorbing end 301 of the mixing unit 30 and is arranged in the heat-absorbing chamber 303; and the condenser 312 It is arranged opposite to the heat release end 302 of the mixing unit 30 and is arranged in the heat release chamber 304.
[0131] In another alternative embodiment, the semiconductor temperature regulator includes a semiconductor refrigeration fin, a first end heat exchanger arranged at the first end of the pelvis and a second end heat exchanger at the second end, and a power supply Device. The power supply device is used to provide electrical energy for the semiconductor refrigeration sheet. By controlling the direction of the power supply current, the first end and the second end of the peltier can be switched in two modes of heat generation and cold generation. For example, under a forward current, the first end is the cold end and the second end is the hot end; after switching the current direction, the first end is switched to the hot end and the second end is switched to the cold end. The mixing unit 30 includes two heat-absorbing chambers 303 and a heat-releasing chamber 304 that are provided with heat insulation and heat preservation; the first end heat exchanger is arranged opposite to the heat-absorbing end 301 of the mixing unit 30 and is arranged in the heat-absorbing chamber 303; The second end heat exchanger is arranged opposite to the heat release end 302 of the mixing unit 30 and is arranged in the heat release chamber 304. According to the actual situation, it is sufficient to determine the first end heat exchanger as the hot end (or cold end) and the second end heat exchanger as the cold end (or hot end).
[0132] When it is necessary to provide accurate energy to the temperature regulating device at the release end, or when the heat transfer between the energy storage station 10 and the temperature regulating device cannot be carried out in the set direction, the unidirectional heat conducting device 31 is activated to reduce the heat of the heat sink 301 It is forced to exchange to the heat release end 302, and then the heat release end 302 transfers the heat to the energy storage station 10 (or the absorption end temperature adjustment device 1011, or the release end temperature adjustment device 1021).
[0133] The intermediate conversion heat exchanger is used to divert the energy released from the energy storage station. The mixing unit neutralizes the energy diverted from the multiple intermediate conversion heat exchangers to obtain the set energy, and then the mixing unit outputs the set energy to the equipment. The side of the thermostat that matches the fixed energy. It can accurately provide matching energy to the temperature adjustment device at the energy release end of the energy storage station. Specifically, a medium of matching temperature can be provided.
[0134] In the embodiment of the present invention, the function of the mixing unit 41 is to mix media with different energies (temperatures) to obtain a media with a set energy (set temperature), and then output the media to a temperature regulating device (temperature regulating at the release end) Device 1021) side. Therefore, in a specific implementation, such as Figure 5a with Figure 5b As shown, the mixing unit 41 has two separate chambers, one is a liquid inlet chamber 411, the other is a liquid return chamber 412, the liquid inlet chamber 411 has one or more liquid inlet pipes 4111, and one or more There are two output and outlet pipes 4112; the liquid return chamber 412 has one or more input and outlet pipes 4122, and one or more output and inlet pipes 4121. An input liquid inlet pipe 4111 and an input liquid outlet pipe 4122 constitute an input end connection pipeline group, and an output liquid inlet pipe 4121 and an output liquid pipe 4112 constitute an output end connection pipeline group. An input end connecting pipeline group is connected with an output end pipeline group of the intermediate heat exchanger, and an output end pipeline group is connected with a terminal heat exchange device on the side of the temperature regulating device. There are two or more communication pipeline groups at the input end of the mixing unit 41, which are used to communicate with the communication pipelines of the first energy output ends of two or more intermediate heat exchangers. The output end connecting pipe group of the mixing unit 41 may be one or more groups. In one group, it is only connected to the terminal heat exchange device of one temperature regulating device. When there are multiple groups, they are respectively connected to the terminal heat exchange devices of multiple temperature regulating devices to provide energy for multiple temperature regulating devices. In addition, at this time, an on-off valve is set on each output port connecting pipeline group to facilitate the control part to communicate The opening and closing of pipelines can provide energy for one or more temperature regulating devices.
