Description

Technical Field

[0001] The present invention relates to the technical field of energy storage battery cabinets, and in particular to an automatic temperature control device for an energy storage battery cabinet and a use method thereof. Background Art

[0002] In the energy storage industry, multiple batteries are usually connected in series and parallel to form a high-voltage or high-energy energy storage battery cabinet for use. However, in the process of the battery in the cabinet body converting the input electrical energy into chemical energy, as the electrical energy is converted into heat energy, the heat energy emitted by the battery will accumulate in the sealed cabinet body, causing the cabinet body to continue to heat up. The accumulated heat energy will reduce the charging and discharging efficiency of the battery itself. At the same time, the accumulation of a certain degree of heat energy will cause the risk of battery spontaneous combustion or even explosion. Therefore, it is necessary to add heat dissipation measures to the battery energy storage cabinet. In addition, in cold weather, the colder air will also reduce the charging and discharging efficiency of the battery itself.

[0003] At present, in order to dissipate heat and keep the battery energy storage cabinet warm, an air conditioner is generally added to the cabinet body for cooling or heating. The temperature of the air conditioner cooling or heating is controlled in conjunction with the temperature sensor in the battery energy storage cabinet, so that the battery energy storage cabinet is at a suitable temperature, thereby improving the charging and discharging efficiency of the battery itself.

[0004] However, when using air conditioning for cooling or heating, due to the different densities of cold air and hot air, the cold air exhausted by the air conditioner will sink directly to the bottom of the cabinet, or the hot air exhausted will float directly to the top of the cabinet, resulting in large local temperature differences inside the battery energy storage cabinet, uneven heat dissipation or heat preservation, and to some extent affecting the charging and discharging efficiency of the battery itself.

[0014] Furthermore, a sealing ring is provided between the flange and the fixing plate, and a sieve plate is provided at the end of the exhaust port.

[0015] A method for using an automatic temperature control device for an energy storage battery cabinet comprises the following steps: S1. Check the sealing of the heat exchange area and the wiring area, and whether the connection of each component is stable; S2. Detect the temperature inside the energy storage battery cabinet through the temperature sensor and feed back the signal to the control system. After receiving the corresponding signal, the control system controls the air conditioner to turn on the cooling or heating mode; S3, the hot air or cold air output from the air conditioner output end enters the air intake chamber through the hot air inlet or the cold air inlet, and then the hot air or cold air enters into different heat exchange areas respectively through the first through holes provided on the partition plate; S4. The cold air or hot air entering the energy conversion area enters the interior of the square sleeve through the second through hole provided at the bottom of the square sleeve, and is guided by the guide plate and the square sleeve, so that the cold air or hot air alternately passes through the air holes provided on the guide plates in turn, and slowly rises from bottom to top around the battery, while taking away the heat from the battery or keeping the battery warm. After the cold air or hot air has exchanged heat with the battery, it is discharged from the exhaust port provided on the other side of the energy storage battery cabinet.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. When the battery needs to be cooled or kept warm, the air conditioner is controlled by the temperature sensor to start the cooling or heating mode; the hot air or cold air outputted from the output end of the air conditioner enters the air intake chamber through the hot air inlet or the cold air inlet, and then the hot air or cold air enters the different heat exchange areas through the first through holes provided on the partition in turn. Since the multiple heat exchange areas are at the same height, the cold air or hot air is prevented from sinking directly to the bottom of the cabinet, or the exhausted hot air is prevented from floating directly to the top of the cabinet, resulting in a large local temperature difference inside the battery energy storage cabinet, thereby preventing the occurrence of uneven heat dissipation or heat preservation, thereby improving the charging and discharging efficiency of the battery itself; 2. The cold air or hot air entering the energy conversion area enters the interior of the square sleeve through the second through hole provided at the bottom of the square sleeve, and is guided by the guide plate and the square sleeve, so that the cold air or hot air alternately passes through the air holes provided on the guide plates in turn, and slowly rises from bottom to top around the battery, taking away the heat on the battery or keeping the battery warm, thereby increasing the contact time between the cold air and the hot air and the battery. At the same time, the spirally rising hot air and the cold air are easy to form a vortex, thereby increasing the heat exchange efficiency between the cold air and the hot air; 3. The energy storage chamber is separated into a wiring area and a heat exchange area by a support plate and a fixing plate to prevent humid air carried by cold or hot air from entering the wiring area, thus preventing short circuit leakage and improving the safety of using the energy storage battery cabinet; 4. The first valve plate is driven to slide on the partition through the cooperation among the driving motor, driving wheel, energy storage battery cabinet, cam, gear block, gear, driven wheel, turntable, vortex groove and guide column, so as to change the number of air holes from the air intake chamber to the heat exchange area according to actual needs, adjust the air intake of each heat exchange area, make up for the difference in heat exchange requirements of different battery packs in different working conditions, and thus improve the charging and discharging efficiency of the battery; 5. Each time the position of the first valve plate is adjusted, the limit block provided on the side of the driving wheel enters the limit groove provided on the driven wheel. The resistance generated by the contact between the limit block and the limit groove limits the rotation of the driven wheel on the energy storage battery cabinet, so as to avoid the external force driving the first valve plate to move accidentally after the position of the first valve plate is adjusted, changing the air intake volume of the heat exchange area, resulting in poor heat exchange effect, thereby ensuring the charging and discharging efficiency of the battery; 6. Through the coordination among the telescopic cylinder, the push block, the square block, the return spring, the dial block, the energy storage battery cabinet, the fifth through hole and the inclined surface, the square block is driven to deflect slightly, so that the subsequent roller can contact with a corner of the square block, thereby improving the efficiency of switching the air conditioner to supply the medium of the energy storage battery cabinet; Then, the rotating shaft is driven to rotate 90 degrees through the cooperation among the telescopic cylinder, the push block, the roller, the square block and the energy storage battery cabinet. Since the second valve body and the third valve body are both arranged on the rotating shaft and are perpendicular to each other, the opening and closing relationship between the first valve plate and the second valve body is changed at the same time, thereby switching the medium supplied by the air conditioner to the energy storage battery cabinet, so that the batteries in the energy storage battery cabinet are at an appropriate temperature, thereby improving the charging and discharging efficiency of the battery; in addition, there is no need to separately set up a power device to drive the second valve body and the third valve body to rotate, thereby reducing the space required for the installation of the power device and the manufacturing cost; 7. The side of the push block contacts the side of the square block, and the resistance generated limits the subsequent rotation of the square block on the energy storage battery cabinet, so as to prevent the external force from accidentally driving the square block to rotate, thereby switching the medium supplied by the air conditioner to the energy storage battery cabinet, causing the temperature inside the energy storage battery cabinet to be too high or too low, affecting the battery charging and discharging efficiency; 8. The cold air or hot air entering the heat exchange area is divided into multiple even portions through the air intake channel, and the corresponding cold air or hot air is delivered to the corresponding batteries through the air intake channel to avoid the temperature of the cold air or hot air rising or falling after the battery in the front exchanges heat with the cold air or hot air, affecting the heat exchange effect on the subsequent batteries, thereby ensuring that the batteries at each position are at a more suitable temperature and improving the charging and discharging efficiency of the batteries at each position.

The component force generated drives the square block 38 to deflect slightly, which facilitates the subsequent roller 40 to contact a corner of the square block 38, thereby improving the efficiency of switching the air conditioner 4 to supply the medium of the energy storage battery cabinet 2, until the protrusion 46 provided at the end of the shift block 43 contacts the energy storage battery cabinet 2. The end of the shift block 43 is provided with a protrusion 46 that contacts the energy storage battery cabinet 2, which limits the sliding trajectory of the shift block 43 to prevent the shift block 43 from falling off the energy storage battery cabinet 2.

[0038] Preferably, Figure 2 As shown, the heat exchange area 16 is provided with a plurality of air inlet channels 47 connected to the first through hole 20 and the second through hole 21, and an air outlet channel 48 connected to the second through hole 21 and the exhaust port 10. The air inlet channels 47 divide the cold air or hot air entering the heat exchange area 16 into multiple uniform portions, and transport the corresponding cold air or hot air to the corresponding battery 1 through the air inlet channels 47, so as to avoid the temperature of the cold air or hot air rising or falling after the battery 1 located in the front exchanges heat with the cold air or hot air, thereby affecting the heat exchange effect on the subsequent battery 1, thereby ensuring that the batteries 1 at each position are at a more suitable temperature, thereby improving the charging and discharging efficiency of the batteries 1 at each position.

[0039] Preferably, Figure 2 and Figure 4 As shown, a sealing ring 49 is provided between the flange 13 and the fixing plate 11 to further prevent humid air carried by cold air or hot air from entering the wiring area 15, thereby preventing short circuit and leakage, thereby improving the safety of using the energy storage battery cabinet 2; at the same time, a sieve plate 50 is provided at the end of the exhaust port 10 to prevent insects and ants from the outside from entering the energy storage battery cabinet 2.

[0040] The present invention provides a method for using an automatic temperature control device for an energy storage battery cabinet, such as Figure 1-Figure 4 As shown, the following steps are included: S1. Check the sealing of the heat exchange area 16 and the wiring area 15 to prevent the moist air carried by the cold air or hot air from entering the wiring area 15, and prevent the occurrence of short circuit leakage, thereby improving the safety of using the energy storage battery cabinet 2, and whether the connection of each component is stable; S2, the temperature inside the energy storage battery cabinet 2 is detected by the temperature sensor 3, and a signal is fed back to the control system. After receiving the corresponding signal, the control system controls the air conditioner 4 to turn on the cooling or heating mode; S3, the hot air or cold air outputted from the output end of the air conditioner 4 enters the air inlet 7 through the hot air inlet 8 or the cold air inlet 9, and then the hot air or cold air enters the different heat exchange areas 16 in turn through the first through holes 20 provided on the partition 5. Since the multiple heat exchange areas 16 are at the same height, it is prevented that the cold air or hot air will directly sink to the bottom of the cabinet, or the exhausted hot air will directly float to the top of the cabinet, resulting in a large local temperature difference inside the battery 1 energy storage cabinet, thereby preventing the occurrence of uneven heat dissipation or heat preservation, and further improving the charging and discharging efficiency of the battery 1 itself; S4. The cold air or hot air entering the energy conversion area enters the interior of the square sleeve 17 through the second through hole 21 provided at the bottom of the square sleeve 17. Through the guide plate 18 and the guide of the square sleeve 17, the cold air or hot air alternately passes through the air holes 19 provided on the guide plates 18 in turn, and slowly rises from bottom to top around the battery 1, taking away the heat on the battery 1 or keeping the battery 1 warm, thereby increasing the contact time between the cold air and the hot air and the battery 1. At the same time, the spirally rising hot air and the cold air are easy to form a vortex, thereby increasing the heat exchange efficiency between the cold air and the hot air; after the cold air or the hot air has exchanged heat with the battery 1, it is discharged from the exhaust port 10 provided on the other side of the energy storage battery cabinet 2.

[0041] Example 1 The present invention provides an automatic temperature control device for an energy storage battery cabinet and a method of using the same. Figure 1-Figure 4 As shown, several batteries 1 are respectively arranged on the fixing plate 11 in advance, and then the square sleeve 17 provided with the guide plate 18 is set on the outside of the battery 1 and connected to the fixing plate 11 at the same time, and then the support plate 14 is connected to the square sleeve 17, and the square sleeve 17 is made to contact with the bottom of the battery 1, so as to form a battery 1 assembly, and then the several battery 1 assemblies are respectively arranged between one of the side plates of the energy storage battery cabinet 2 and the partition plate 5, and then the remaining side plates, top plate and bottom plate of the energy storage battery cabinet 2 are installed, so as to realize the assembly of the energy storage battery cabinet 2; When the battery 1 needs to be cooled or kept warm, the temperature inside the energy storage battery cabinet 2 is detected by the temperature sensor 3, and a signal is fed back to the control system. After receiving the corresponding signal, the control system controls the air conditioner 4 to turn on the cooling or heating mode; The hot air or cold air outputted from the output end of the air conditioner 4 enters the air inlet 7 through the hot air inlet 8 or the cold air inlet 9, and then the hot air or cold air enters the different heat exchange areas 16 in turn through the first through holes 20 provided on the partition 5. Since the multiple heat exchange areas 16 are at the same height, it is prevented that the cold air or hot air will directly sink to the bottom of the cabinet, or the exhausted hot air will directly float to the top of the cabinet, resulting in a large local temperature difference inside the battery 1 energy storage cabinet, thereby preventing the occurrence of uneven heat dissipation or heat preservation, and further improving the charging and discharging efficiency of the battery 1 itself; The cold air or hot air entering the energy conversion area enters the interior of the square sleeve 17 through the second through hole 21 provided at the bottom of the square sleeve 17, and is guided by the guide plate 18 and the square sleeve 17, so that the cold air or hot air alternately passes through the air holes 19 provided on the guide plates 18 in turn, and slowly rises from bottom to top around the battery 1, taking away the heat on the battery 1 or keeping the battery 1 warm, thereby increasing the contact time between the cold air and the hot air and the battery 1, and at the same time, the spirally rising hot air and the cold air are easy to form a vortex, thereby increasing the heat exchange efficiency between the cold air and the hot air; after the cold air or the hot air has exchanged heat with the battery 1, it is discharged from the exhaust port 10 provided on the other side of the energy storage battery cabinet 2, and the cold air or the hot air is continuously input into the energy storage battery cabinet 2 through the air conditioner 4, so as to eliminate the heat generated in the conversion process of the battery 1, or to prevent the battery 1 from being in a low temperature state, thereby improving the charging and discharging efficiency of the battery 1; In addition, the energy storage chamber 6 is separated into a wiring area 15 and a heat exchange area 16 by the support plate 14 and the fixing plate 11, so as to prevent humid air carried by cold air or hot air from entering the wiring area 15 and prevent short circuit leakage, thereby improving the safety of using the energy storage battery cabinet 2.

[0042] Example 2 On the basis of Example 1, Figure 3-Figure 9As shown, when it is necessary to change the air intake amount of the heat exchange area 16, the driving motor drives the driving wheel 30 to rotate on the energy storage battery cabinet 2, so that the limit block 31 slides out of the limit groove 29, and the restriction on the rotation of the driven wheel 28 on the energy storage battery cabinet 2 is released; then, the tooth block 34 provided on the cam 33 contacts the gear 32, driving the driven wheel 28 and the turntable 25 to rotate together, so that the vortex groove 26 provided on one side of the turntable 25 further contacts the guide column 27, and the component force generated after the contact drives the guide column 27 to move vertically, thereby driving the first valve plate 23 to slide on the partition 5, so as to change the number of air holes from the air intake chamber 7 to the heat exchange area 16 according to actual needs, and adjust The air intake of each heat exchange area 16 is regulated to make up for the difference in heat exchange requirements of different battery groups 1 under different working conditions, thereby improving the charging and discharging efficiency of the battery 1; in addition, each time the position of the first valve plate 23 is adjusted, the limit block 31 provided on the side of the driving wheel 30 enters the limit groove 29 provided on the driven wheel 28, and the resistance generated by the contact between the limit block 31 and the limit groove 29 limits the rotation of the driven wheel 28 on the energy storage battery cabinet 2, so as to avoid the external force accidentally driving the first valve plate 23 to move after the position of the first valve plate 23 is adjusted, thereby changing the air intake of the heat exchange area 16, resulting in poor heat exchange effect, thereby ensuring the charging and discharging efficiency of the battery 1.

[0043] Example 3 On the basis of Example 1, Figure 6 , Fig.10 , Fig.11 and Fig.12 As shown, when it is necessary to switch the medium supplied by the air conditioner 4 to the energy storage battery cabinet 2, the push block 39 is driven to retract by the telescopic cylinder 41, so that the side of the push block 39 is no longer in contact with the square block 38, thereby releasing the restriction on the rotation of the square block 38 on the energy storage battery cabinet 2; subsequently, the rebound force generated by the compression of the return spring 45 drives the shift block 43 to move downward on the energy storage battery cabinet 2, so that the shift block 43 enters the fifth through hole 42 and contacts the fifth through hole 42 through the inclined surface 44. The component force generated drives the square block 38 to deflect slightly, which is convenient for the subsequent roller 40 to contact a corner of the square block 38, thereby improving the efficiency of switching the medium supplied by the air conditioner 4 to the energy storage battery cabinet 2, until the protrusion 46 provided at the end of the shift block 43 contacts the energy storage battery cabinet 2. At this time, the inclined surface 44 provided at the end of the shift block 43 has not completely entered the fifth through hole 42; Then, the push block 39 is extended by the telescopic cylinder 41, and the roller 40 provided on one side of the push block 39 contacts one corner of the square block 38, and the component force generated drives the square block 38 to rotate on the energy storage battery cabinet 2 until the side of the square block 38 contacts the push block 39, thereby driving the rotating shaft 37 to rotate 90 degrees. Since the second valve body 35 and the third valve body 36 are both arranged on the rotating shaft 37 and are perpendicular to each other, the second valve body 35 and the third valve body 36 are simultaneously driven to rotate 90 degrees, changing the positional relationship between the second valve body 35 and the third valve body 36 and the flow direction of the pipeline, changing the opening and closing relationship between the second valve body 35 and the third valve body 36, and then switching the medium supplied by the air conditioner 4 to the energy storage battery cabinet 2, so that the battery 1 in the energy storage battery cabinet 2 is at an appropriate temperature, thereby improving the charging and discharging efficiency of the battery 1; in addition, there is no need to separately set up a power device to drive the second valve body 35 and the third valve body 36 to rotate, thereby reducing the space required for the installation of the power device and the manufacturing cost; In addition, by the side of the push block 39 contacting the side of the square block 38, the resistance generated limits the subsequent rotation of the square block 38 on the energy storage battery cabinet 2, thereby preventing external forces from accidentally driving the square block 38 to rotate, and then switching the air conditioner 4 to supply the medium of the energy storage battery cabinet 2, causing the temperature inside the energy storage battery cabinet 2 to be too high or too low, affecting the charging and discharging efficiency of the battery 1.

[0044] Example 4 On the basis of Example 1, Figure 2 and Figure 4 As shown, a plurality of air inlet channels 47 connected to the first through hole 20 and the second through hole 21 are provided in the heat exchange area 16. The air inlet channels 47 divide the cold air or hot air entering the heat exchange area 16 into multiple uniform portions, and deliver the corresponding cold air or hot air to the corresponding battery 1 through the air inlet channels 47, so as to avoid the temperature of the cold air or hot air rising or falling after the battery 1 located in the front exchanges heat with the cold air or hot air, thereby affecting the heat exchange effect of the subsequent battery 1, thereby ensuring that the batteries 1 at various positions are at a more suitable temperature, improving the charging and discharging efficiency of the batteries 1 at various positions, and the cold air or hot air after the heat exchange is discharged from the energy storage battery cabinet 2 from the air outlet channels 48 and the exhaust port 10; In addition, a sealing ring 49 is provided between the flange 13 and the fixing plate 11 to further prevent humid air carried by cold air or hot air from entering the wiring area 15, thereby preventing short circuit and leakage, thereby improving the safety of using the energy storage battery cabinet 2; at the same time, a sieve plate 50 is provided at the end of the exhaust port 10 to prevent insects and ants from the outside from entering the energy storage battery cabinet 2.
