DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] See also Figures 1 to 12 , the utility model provides a portable energy storage power supply.

[0035] The portable energy storage power supply includes a shell 100, a battery module 200, a first radiator 300 and a semiconductor refrigeration module 400. The shell 100 has a accommodating cavity; the battery module 200 is arranged in the accommodating cavity, the battery module 200 includes a plurality of single cells 210 and a first liquid cooling plate 220 in contact with the plurality of single cells 210, the first liquid cooling plate 220 can perform heat exchange with the plurality of single cells 210, and a first liquid cooling channel 221 is arranged in the first liquid cooling plate 220; the first radiator 300 is arranged in the accommodating cavity, and the first radiator 300 is provided with a first heat dissipation channel; the semiconductor refrigeration module 400 includes a cooling end 410 and a heating end 420, the cooling end 410 is provided with a cooling channel, the heating end 420 is provided with a heating channel, the heating channel is connected to the first heat dissipation channel to form a first circuit, and the cooling channel is connected to the first liquid cooling channel 221 to form a second circuit.

[0036] Specifically, the first circuit and the second circuit are independent of each other, and the first circuit and the second circuit are cooled and heat exchanged through the semiconductor refrigeration module 400. The semiconductor refrigeration module 400 is energized by connecting a power source to form a cooling end 410 and a heating end 420. When current passes through the semiconductor refrigeration module 400, heat transfer will occur between the two ends, and the heat will be transferred from one side to the other side, thereby generating a temperature difference to form a cold and hot end. In this embodiment, the cooling end 410 is used to cool the coolant flowing through it, and the first heat dissipation channel of the first radiator 300 circulates the coolant to cool the heating channel flowing through the heating end 420. When the heating end 420 is cooled, the cooling end 410 is also cooled, so as to form a refrigeration system, which improves the heat dissipation effect by replacing air cooling with liquid cooling, and performs refrigeration without noise.

[0037] The portable energy storage power supply of the utility model adopts liquid cooling to replace traditional air cooling. On the one hand, the design of the heat dissipation holes is cancelled, which can ensure the sealing of the entire structure and have a good waterproof and dustproof effect, and can be used safely without fear of wind and rain; on the other hand, the liquid cooling output is silent and noiseless; on the other hand, the portable energy storage power supply of the utility model can realize intelligent temperature control. Since the heat dissipation effect of the semiconductor refrigeration module 400 is better than air cooling, the portable energy storage power supply has a wider operating temperature range, for example: it can be used in a wide temperature range of -20°C to 45°C.

[0038] See also Figure 2 and Figure 6 Furthermore, the portable energy storage power supply also includes an inverter 500, a second liquid cooling plate 600 and a second radiator 700 arranged in the accommodating cavity, the second liquid cooling plate 600 is sandwiched between the inverter 500 and the battery module 200, the inverter 500 is electrically connected to the battery module 200, the second radiator 700 has a second heat dissipation channel, the second liquid cooling plate 600 has a second liquid cooling channel 610, and the second heat dissipation channel is connected to the second liquid cooling channel 610 to form a third circuit. In this way, the first liquid cooling plate 220 mainly dissipates heat for the battery module 200, and the second liquid cooling plate 600 simultaneously assists the inverter 500 and the battery module 200 in heat dissipation, further enhancing the heat dissipation effect. The battery module 200 is doubly cooled by the first liquid cooling plate 220 and the second liquid cooling plate 600, and the second liquid cooling plate 600 cools the inverter 500.

Specifically, the first circuit, the second circuit, and the third circuit are independent water circuits. The first circulation pump 810 is used to provide circulation power to the heating channel of the semiconductor refrigeration module 400 and the first heat dissipation channel of the first radiator 300; the second circulation pump 820 is used to provide circulation power to the refrigeration channel of the semiconductor refrigeration module 400 and the first liquid cooling channel 221 of the first liquid cooling plate 220; the third circulation pump 830 is used to provide circulation power to the second heat dissipation channel of the second radiator 700 and the second liquid cooling channel 610 of the second liquid cooling plate 600.

[0040] See also Figures 2 to 4 Furthermore, the portable energy storage power supply also includes a plurality of hoses 840, the heating channel, the first heat dissipation channel, and the first circulation pump 810 are sequentially connected through the hoses 840, the cooling channel, the first liquid cooling channel 221, and the second circulation pump 820 are sequentially connected through the hoses 840, and the second heat dissipation channel, the second liquid cooling channel 610, and the third circulation pump 830 are sequentially connected through the hoses 840. The hoses 840 can be adapted to different internal spaces to improve space utilization. Of course, in addition to this, hard pipes can also be used to connect the various channels.

[0041] See also Fig. 9 and Fig.11 Further, the first radiator 300 includes a first heat dissipation housing 310, a first heat dissipation pipe row 320 installed on the first heat dissipation housing 310, and a first fan 330 installed on the first heat dissipation pipe row. The first heat dissipation pipe row 320 has a first heat dissipation channel. The first heat dissipation housing 310 is provided with a first air outlet grille 340. The first heat dissipation pipe row 320 is arranged in a grid shape. The first fan 330 is used to dissipate heat from the first heat dissipation pipe row 320. Specifically, the coolant flows in the first heat dissipation channel inside the first heat dissipation pipe row 320, and the first fan 330 blows air to dissipate heat from the first heat dissipation pipe row 320. Through the first heat dissipation pipe row 320 arranged in a grid shape, the coolant flows in a circuitous manner in the first heat dissipation channel to fully exchange heat, increase the contact area between the first heat dissipation pipe row 320 and the air, and facilitate the air to pass through the grid-shaped first heat dissipation pipe row 320 and be discharged from the first air outlet grille 340, so as to take away the heat of the internal coolant and play a role in heat dissipation.

[0042] See also Fig.10 and Fig.12Further, the second radiator 700 includes a second heat dissipation housing 710, a second heat dissipation pipe row 720 installed on the second heat dissipation housing 710, and a second fan 730 installed on the second heat dissipation pipe row. The second heat dissipation pipe row 720 has a second heat dissipation channel. The second heat dissipation housing 710 is provided with a second air outlet grille 740. The second heat dissipation pipe row 720 is arranged in a grid shape. The second fan 730 is used to dissipate heat from the second heat dissipation pipe row 720. Specifically, the coolant flows in the second heat dissipation channel inside the second heat dissipation pipe row 720, and the second fan 730 blows air to dissipate heat from the second heat dissipation pipe row 720. Through the second heat dissipation pipe row 720 arranged in a grid shape, the coolant flows in a circuitous manner in the second heat dissipation channel to fully exchange heat, increase the contact area between the second heat dissipation pipe row 720 and the air, and facilitate the air to pass through the grid-shaped second heat dissipation pipe row 720 and be discharged from the second air outlet grille 740, so as to take away the heat of the internal coolant and play a role in heat dissipation.

[0043] See also Figure 2 Furthermore, a plurality of single cells 210 are attached with a heating film 900, and the heating film 900 is used to preheat the single cells 210. The portable energy storage power supply has a preheating mode. When the portable energy storage power supply is in the preheating mode, the heating film 900 starts heating. It is understandable that each single cell 210 has an optimal working temperature. When in a low temperature environment, if the single cell 210 works directly, its life and working efficiency will be affected. By setting the heating film 900, when the portable energy storage power supply is ready to work, the heating film 900 is started to preheat the plurality of single cells 210, and the battery module 200 is used after it is preheated to the optimal working temperature. The portable energy storage power supply of the utility model has a built-in preheating module, which can preheat the battery to a suitable working temperature before use, and can easily cope with severe cold climate areas. The preheating function cooperates with the heat dissipation and refrigeration of the semiconductor refrigeration module 400, so that the portable energy storage power supply has a wider operating temperature range, for example: it can be used in a wide temperature range of -20°C to 45°C.

[0044] See also Fig.11 In order to speed up the preheating efficiency of the portable energy storage power supply, further, when the portable energy storage power supply is in the preheating mode, the semiconductor refrigeration module 400 is turned off. In this way, the semiconductor refrigeration module 400 is turned off and does not dissipate heat to the first liquid cooling plate 220, and the semiconductor refrigeration module 400 does not dissipate heat to the battery module 200, which speeds up the preheating efficiency of the portable energy storage power supply to a certain extent.

[0045] Furthermore, the first liquid cooling plate 220 and the second liquid cooling plate 600 are made of aluminum. Aluminum has high thermal conductivity, which can facilitate heat exchange cooling between the first liquid cooling plate 220 and the battery module 200, and heat exchange cooling between the second liquid cooling plate 600, the battery module 200 and the inverter 500.

[0046] See also Figures 7 and 8 Furthermore, the first liquid cooling channel 221 and the second liquid cooling channel 610 are both arranged in a curved and circuitous manner. In this way, the flow path of the coolant is extended, so that the heat exchange between the coolant and the inside of the channel is more sufficient, and the heat dissipation and refrigeration effect of the coolant inside the channel is better. In order to improve the heat exchange effect, the cooling channel, the heating channel, the first heat dissipation channel, and the second heat dissipation channel can also be arranged in a curved and circuitous manner.

[0047] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
