Description

Technical Field

[0001] The present application relates to but is not limited to the technical field of energy storage temperature control products, and specifically refers to an energy storage temperature control device. Background Art

[0002] Energy storage temperature control products are products used to manage and control the temperature of energy storage devices such as batteries and supercapacitors. During the use of energy storage devices, heat is generated due to the chemical reaction inside the battery or supercapacitor. If the temperature is too high, it will not only affect the performance and life of the energy storage device, but may also cause safety accidents. Therefore, energy storage temperature control products monitor the temperature of energy storage devices and automatically control them according to the set temperature range to ensure the safe, stable and efficient operation of energy storage devices. Energy storage temperature control products are widely used in electric vehicles, solar energy storage systems, wind power generation and other fields.

[0003] In energy storage temperature control products, the electrical components in the electric control cabinet heat up seriously, and a refrigerant radiator is required to dissipate the heat. In one case, the refrigerant radiator is hard-connected to the refrigerant system through copper pipes, which means that the electric control cabinet cannot be moved without disconnecting the copper pipes, affecting the maintenance of the components behind the electric control cabinet; in another case, the refrigerant radiator is soft-connected to the refrigerant system, which requires a larger space to move the electric control cabinet without disconnecting the copper pipes.

DETAILED DESCRIPTION

[0045] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0046] like Figure 1-Figure 8 As shown, an embodiment of the present application provides an energy storage temperature control device, including a housing 31, a first electric control cabinet 32, a second electric control cabinet 33, a heat dissipation device and a first component.

[0047] The housing 31 has an inspection port, so that the components in the housing 31 (such as the second electric control cabinet 33 and the first component, etc.) can be inspected through the inspection port. The inspection port can be set at the front side of the housing 31, so that the components in the housing 31 can be inspected (such as inspected, repaired, disassembled, etc.) from the front side. Of course, the inspection port can also be set on the left side, right side, rear side, etc. of the housing 31 as needed.

[0048] The first electric control cabinet 32 ​​is fixed in the casing 31, and a first electrical component is provided in the first electric control cabinet 32; the second electric control cabinet 33 is installed in the casing 31, and a second electrical component is provided in the second electric control cabinet 33, and the heating value of the second electrical component is set to be smaller than the heating value of the first electrical component (during the same length of time during the operation of the energy storage temperature control device, the heating value of the second electrical component is smaller than the heating value of the first electrical component).

[0049] The heat dissipation device is installed in the housing 31 and is configured to dissipate heat for the first electric control cabinet 32 ​​and to perform air cooling on the second electric control cabinet 33. The heat dissipation device is configured to dissipate heat for the first electric control cabinet 32 ​​and the second electric control cabinet 33 in different heat dissipation modes to prevent the first electric control cabinet 32 ​​and the second electric control cabinet 33 from being overheated and affecting their normal operation.

[0050] The second electric control cabinet 33 has a working state and an inspection state, wherein the first component is installed in the housing 31. In the working state, the first component is arranged to be located at a side of the second electric control cabinet 33 away from the inspection port, such as: the inspection port can be arranged at the front side of the housing 31, and the first component can be located at the rear side of the second electric control cabinet 33 in the working state; in the inspection state, such as Figure 1 As shown, the first component is exposed at the inspection port so as to be inspected through the inspection port. Specifically, the second electric control cabinet 33 can be switched between a working state and an inspection state. In the working state, the second electric control cabinet 33 shields at least part of the first component; in the inspection state, the second electric control cabinet 33 does not shield the first component, so that the first component can be exposed at the inspection port so as to be inspected through the inspection port.

[0051] In the energy storage temperature control device, two electric control cabinets are designed: a first electric control cabinet 32 ​​and a second electric control cabinet 33. The first electrical components with serious heat generation are concentrated in the first electric control cabinet 32, and the second electrical components with less serious heat generation are concentrated in the second electric control cabinet 33, so that the heat dissipation device adopts different heat dissipation methods to dissipate heat in the first electric control cabinet 32 ​​and the second electric control cabinet 33 according to the heat generation situation to meet the heat dissipation requirements. Since the second electrical components in the second electric control cabinet 33 do not generate serious heat, there is no need to use a refrigerant radiator to dissipate heat, but air cooling is used for heat dissipation. Therefore, the second electric control cabinet 33 can be set to be movable so that the second electric control cabinet 33 can be switched between the working state and the maintenance state, so that in the maintenance state, the second electric control cabinet 33 does not block the first components, thereby facilitating the maintenance of the first components through the maintenance port.

[0052] The energy storage temperature control device of the embodiment of the present application facilitates the maintenance of the first component on one side of the second electric control cabinet 33 while ensuring the heat dissipation effect of the two electric control cabinets.

[0053] In some exemplary embodiments, Figure 1 and Figure 2 As shown, a fixing frame 311 is provided in the housing 31, and a first side of the second electric control cabinet 33 is rotatably connected to the fixing frame 311, so that the second electric control cabinet 33 can be switched between a working state and a maintenance state; a second side of the second electric control cabinet 33 is detachably fixedly connected to the fixing frame 311, and in the working state, the second side of the second electric control cabinet 33 is fixedly connected to the fixing frame 311; Figure 1 and Figure 2In the maintenance state shown, the second side of the second electric control cabinet 33 is separated from the fixing frame 311 .

[0054] In the energy storage temperature control device, the first side of the second electric control cabinet 33 is rotatably connected to the fixing frame 311, so that the second electric control cabinet 33 can rotate relative to the fixing frame 311, so that the second electric control cabinet 33 can switch between the working state and the maintenance state. For the flippable second electric control cabinet 33, in the working state, in addition to the first side of the second electric control cabinet 33 being rotatably connected to the fixing frame 311, its second side is also fixedly connected to the fixing frame 311, which enhances the fixing effect of the second electric control cabinet 33 so as to firmly keep the second electric control cabinet 33 in the working state. When the first component needs to be repaired, the connection between the second side of the second electric control cabinet 33 and the fixing frame 311 can be disassembled so as to flip the second electric control cabinet 33 and switch the second electric control cabinet 33 to the maintenance state, at which time the second side of the second electric control cabinet 33 is separated from the fixing frame 311 and does not block the first component so as to repair the first component through the inspection port.

[0055] In some exemplary embodiments, the first side of the second electric control cabinet 33 is the upper side, the lower side, the left side or the right side of the second electric control cabinet 33, and the first side of the second electric control cabinet 33 is adjacent to or opposite to the second side. Figure 1 , Figure 2 and Figure 7 As shown, the first side of the second electric control cabinet 33 can be the right side of the second electric control cabinet 33, and the second side of the second electric control cabinet 33 can be the upper side of the second electric control cabinet 33, that is, the right side of the second electric control cabinet 33 can be rotatably connected to the fixed frame 311, and the upper side of the second electric control cabinet 33 can be detachably fixedly connected to the fixed frame 311.

[0056] In some exemplary embodiments, the second side of the second electric control cabinet 33 is hooked to the fixing frame 311 and fixedly connected by a first fastener 351 (eg, a screw). Figure 2 and Figure 7 As shown, the upper part of the second electric control cabinet 33 is provided with a hanging hole 333 and a first fixing hole 335, the right side of the second electric control cabinet 33 is provided with a rotating connection part (such as a hinge, etc.) 334, the fixing frame 311 is provided with a hook 312 and a second fixing hole 313, and the right side of the second electric control cabinet 33 can be rotatably connected with the fixing frame 311 through the rotating connection part 334. The second electric control cabinet 33 rotates relative to the fixing frame 311, so that the hanging hole 333 of the second electric control cabinet 33 can be hung on the hook 312 of the fixing frame 311, so as to realize the pre-fixation of the second electric control cabinet 33 and the fixing frame 311, and facilitate the upper side of the second electric control cabinet 33 and the fixing frame 311 to be fixedly connected through the first fastener 351. The first fastener 351 can pass through the first fixing hole 335 and the second fixing hole 313 to fix the second electric control cabinet 33 to the fixing frame 311.

[0057] In some exemplary embodiments, Figure 1 As shown, the first electric control cabinet 32 ​​and the second electric control cabinet 33 are arranged side by side and are both close to the inspection port. Specifically, the first electric control cabinet 32 ​​can be located above the second electric control cabinet 33 and close to the inspection port on the front side of the housing 31. Of course, the first electric control cabinet 32 ​​can also be arranged below, on the left side, or on the right side of the second electric control cabinet 33.

[0058] The first electric control cabinet 32 ​​and the second electric control cabinet 33 are arranged side by side and close to the inspection port, so that the first electric control cabinet 32 ​​and the second electric control cabinet 33 in working state can be inspected through the inspection port.

[0059] In some exemplary embodiments, the heat dissipation device includes a refrigerant radiator, which is configured to dissipate heat from the first electric control cabinet 32 ​​and is located on a side of the first electric control cabinet 32 ​​away from the inspection port.

[0060] The refrigerant radiator is used to dissipate heat for the first electrical component that generates serious heat, and the heat dissipation effect is good. The refrigerant radiator is located on the side of the first electric control cabinet 32 ​​away from the inspection port, such as: the refrigerant radiator can be located at the rear side of the first electric control cabinet 32, so that the refrigerant radiator does not affect the inspection of the first electric control cabinet 32 ​​through the inspection port.

[0061] The first electric control cabinet 32 ​​cannot be moved without disconnecting the copper pipe (the refrigerant radiator and the refrigerant system are hard-connected through the copper pipe). Therefore, the components on the rear side of the first electric control cabinet 32 ​​are difficult to maintain. Components that do not require maintenance or are not easily damaged can be designed on the rear side of the first electric control cabinet 32.

[0062] In some exemplary embodiments, the heat dissipation device further includes a heat dissipation fan, and the heat dissipation fan is configured to dissipate heat from the second electric control cabinet 33 .

[0063] The second electrical components that do not generate heat seriously are concentrated in the second electric control cabinet 33, and the airflow formed by the cooling fan is used to cool the second electric control cabinet 33, which can meet the heat dissipation requirements of the second electric control cabinet 33; and the second electric control cabinet 33 uses air cooling to dissipate heat, so that the second electric control cabinet 33 can be designed as a flippable electric control cabinet, which is convenient for maintaining the first components on the rear side of the second electric control cabinet 33. Therefore, components that need to be maintained or are easily damaged can be designed on the rear side of the second electric control cabinet 33.

[0064] In some exemplary embodiments, Figure 6 As shown, the first electrical component includes a module board 321 for controlling the operation of the heat dissipation fan.

[0065] Among them, two cooling fans can be provided, and two module boards 321 for controlling the operation of the cooling fans can be provided and arranged in the first electric control cabinet 32. The two module boards 321 generate severe heat during operation, and the refrigerant in the refrigerant radiator can be used for heat dissipation.

[0066] In some exemplary embodiments, the energy storage temperature control device includes a refrigerant system and a coolant system, the refrigerant system and the coolant system are configured to exchange heat, and the coolant system is configured to heat or cool the device to be temperature controlled.

[0067] Specifically, Figure 8 As shown, the refrigerant system may include a compressor 1, a fluorine side temperature sensor 2, a fluorine side needle valve 3, a condensing pressure sensor 4, a high pressure switch 5, a condenser 6, a condensing fan 7, a fluorine cold plate 8, a fluorine side filter 9, an electronic expansion valve 10, a plate heat exchanger 11, an evaporation pressure sensor 12, a compressor electric heating belt 13, etc. The coolant system may include an exhaust valve 14, a PTC electric heater 15, a water side temperature sensor 16, a water pressure sensor 17, a water side needle valve 18, a safety valve 19, a water side filter 20, a liquid replenishment tank 21, a liquid replenishment pump 22, a one-way valve 23, an expansion tank 24, a stop valve 25, a ball valve 26, a circulating pump 27, a load 28, a float switch 29, an ambient temperature sensor 30, etc. The coolant of the coolant system and the refrigerant of the refrigerant system may exchange heat in the plate heat exchanger 11.

[0068] The energy storage temperature control device may include an external system of the unit (as shown in the rectangular box Q1) and an internal system of the unit (as shown in the rectangular box Q2), the coolant system may include a part of the external system of the unit and the internal system of the unit, and the refrigerant system may include another part of the internal system of the unit.

[0069] The coolant system may be a water system using water as a cooling medium, and of course, other fluids may be used as cooling medium. The components of the coolant system in the internal system of the unit (as shown in the rectangular frame Q3) are non-flammable and removable, so the components of the coolant system in the internal system of the unit can be disposed as a whole on a side (e.g., the rear side) of the second electric control cabinet 33 away from the inspection port, so as to be inspected through the inspection port.

[0070] The refrigerant system can be a fluorine system, and the sensors and other components in the fluorine system (as shown in the rectangular frame Q4) can be copper pipes for welding. Generally, the installation scene does not allow hot work operations, so the unit needs to be disassembled as a whole and repaired in a specific maintenance place. Therefore, at least part of the refrigerant system can be set on the side of the first electric control cabinet 32 ​​away from the inspection port (such as: the back side), such as: the refrigerant system as a whole can be set on the side of the first electric control cabinet 32 ​​and the second electric control cabinet 33 away from the inspection port. The refrigerant system can be hard-connected to the refrigerant radiator that dissipates heat for the first electric control cabinet 32 ​​(such as: hard-connected through a copper pipe). Compared with the soft connection structure, the hard connection structure can reduce space occupancy.

[0071] In some exemplary embodiments, Figure 8As shown, in the coolant system, the circulating pump 27 is configured to drive the coolant to flow in the coolant pipeline so that the coolant circulates in the coolant pipeline to achieve heat exchange between the coolant and the refrigerant in the refrigerant system, and use the coolant to heat or cool the equipment to be temperature controlled.

[0072] like Figure 7 As shown, the energy storage temperature control device also includes a main control board 331 for controlling the operation of the energy storage temperature control device and a frequency conversion board 332 for controlling the operation of the circulation pump, and the second electrical component includes at least one of the main control board 331 and the frequency conversion board 332.

[0073] The main control board 331 and the frequency conversion board 332 do not generate much heat, and can be integrated into the second electric control cabinet 33 and dissipated by air cooling.

[0074] In some exemplary embodiments, Figure 8 As shown, the coolant system includes sensors and control valves. The sensors (such as water side temperature sensor 16, water pressure sensor 17, etc.) are configured to detect working parameters of the coolant system (such as temperature, pressure and other parameters of the coolant system). The control valves (such as safety valve 19, one-way valve 23, stop valve 25, ball valve 26, etc.) are arranged in the coolant pipeline and control the on-off of the coolant pipeline.

[0075] The first component includes at least one of a sensor, a control valve, and a circulation pump. The first component may also include at least one of a liquid replenishing tank 21 and a liquid replenishing pump 22 .

[0076] The sensors, control valves and other components of the coolant system are easily damaged and need frequent maintenance. The components of the coolant system are connected by threads, clamps, clamps and other means, and do not require hot welding. Therefore, they can be repaired and maintained with tools at the inspection port of the casing 31. Therefore, the components of the coolant system that need to be maintained can be designed on the side of the second electric control cabinet 33 away from the inspection port. The exhaust valve (such as: automatic exhaust valve) 14 and the filling / discharge port in the coolant system are not on the side of the second electric control cabinet 33 away from the inspection port. Because the exhaust needs to be designed at the highest point, a separate inspection port is opened.

[0077] In some exemplary embodiments, Figure 8 As shown, in the coolant system, the liquid replenishing tank 21 is connected to the coolant pipeline, and the liquid replenishing pump 22 is fixed to the liquid replenishing tank 21 and is configured to transport the coolant in the liquid replenishing tank 21 to the coolant pipeline.

[0078] like Figure 1-Figure 4As shown, the liquid infusion tank (such as a water tank) 21 is used as a mounting bracket for the liquid infusion pump 22, and the liquid infusion pump 22 is fixed on the liquid infusion tank 21, so that the liquid infusion tank 21 can be used for multiple purposes. Compared with the technical solution of separately installing and fixing the liquid infusion pump 22 and the liquid infusion tank 21, which results in occupying a large space, the solution of fixing the liquid infusion pump 22 on the liquid infusion tank 21 in the embodiment of the present application is conducive to simplifying the structure and saving space.

[0079] In some exemplary embodiments, Figure 1-Figure 4 As shown, the infusion pump 22 is installed with a support plate 34 , one side of the support plate 34 is snap-fitted to the infusion tank 21 , and the other side of the support plate 34 is detachably connected to the infusion tank 21 via a second fastener (eg, a screw) 352 .

[0080] The infusion pump 22 is mounted on the support plate 34 (e.g., the infusion pump 22 and the support plate 34 can be fixedly connected by screws), one side of the support plate 34 is snap-fitted with the infusion tank 21, and the other side is connected to the infusion tank 21 by the second fastener 352, so that the infusion pump 22 can be fixed to the infusion tank 21 by the support plate 34. Compared with the infusion pump 22 being fixed to the infusion tank 21 by screws, which makes it inconvenient to fix the infusion pump 22, and all the screws fixing the infusion pump 22 need to be removed when inspecting the infusion pump 22, which makes disassembly inconvenient, in the solution of the embodiment of the present application, one side of the support plate 34 fixedly connected to the infusion pump 22 is snap-fitted with the infusion tank 21, and the other side is connected to the infusion tank 21 by the second fastener 352, which reduces the number of the second fasteners 352 and facilitates the disassembly and assembly of the infusion pump 22.

[0081] In some exemplary embodiments, Figure 1-Figure 4 As shown, the fluid replenishment pump 22, the support plate 34 and the fluid replenishment tank 21 are located on the side of the second electric control cabinet 33 away from the inspection port, the side of the support plate 34 away from the second electric control cabinet 33 is snap-connected with the fluid replenishment tank 21, and the side of the support plate 34 close to the second electric control cabinet 33 is detachably connected to the fluid replenishment tank 21 via a second fastener 352.

[0082] The support plate 34 is fixed only on one side close to the second electric control cabinet 33 (the side close to the inspection port) with the second fastener 352, and the side of the support plate 34 away from the second electric control cabinet 33 (the side away from the inspection port) is clamped with a clamping structure. When maintaining and repairing the infusion pump 22, the infusion pump 22 and the support plate 34 can be disassembled and assembled as a whole, and can be disassembled at the inspection port, which is convenient for the maintenance and repair of the infusion pump 22.

[0083] In some exemplary embodiments, Figure 1-Figure 4As shown, the fluid replenishment pump 22 is fixed above the fluid replenishment tank 21, and a clamping plate 36 is fixed above the fluid replenishment tank 21, and a clamping groove is formed between the clamping plate 36 and the upper end surface of the fluid replenishment tank 21, and the slot of the clamping groove faces the side where the inspection port is located (such as: towards the front side), and the side of the support plate 34 away from the inspection port (such as: the rear side) is clamped into the slot from the slot.

[0084] A side of the support plate 34 close to the inspection port (eg, the front side) is provided with a downwardly bent edge 341 , and a box wall of the liquid replenishing tank 21 close to the inspection port (eg, the front box wall) is detachably connected to the edge 341 via a second fastener 352 .

[0085] The slot formed by the snap-in plate 36 and the upper end surface of the fluid replenishment tank 21 faces the inspection port on the front side, so that the support plate 34 can be detached from or inserted into the slot by sliding the support plate 34 and the fluid replenishment pump 22 back and forth; the front side of the support plate 34 near the inspection port is provided with a downwardly bent edge 341, and the edge 341 can be connected to the front box wall of the fluid replenishment tank 21 near the inspection port through a second fastener 352, so as to facilitate the disassembly and assembly of the second fastener 352, and then facilitate the disassembly and assembly of the support plate 34 and the fluid replenishment pump 22.

[0086] When repairing the rehydration pump 22, the first fastener 351 between the second electric control cabinet 33 and the fixing frame 311 can be removed first, and the second electric control cabinet 33 can be turned over; then, the second fastener 352 can be removed, and the clamp connecting the rehydration pump 22 and the coolant pipeline can be removed; finally, the rehydration pump 22 and the support plate 34 can be slid forward as a whole to disengage the support plate 34 from the slot, so that the rehydration pump 22 and the support plate 34 can be removed.

[0087] In some exemplary embodiments, the condensing fan 7 may be used as a heat dissipation fan for the second electric control cabinet 33 , or a heat dissipation fan may be separately provided to dissipate heat for the second electric control cabinet 33 .

[0088] In summary, the energy storage temperature control device of the embodiment of the present application is designed with two electric control cabinets, and the first electrical components with serious heating are concentrated in the first electric control cabinet 32, and the refrigerant radiator is used to dissipate the heat for the first electrical components with serious heating. The first electric control cabinet 32 ​​cannot be moved without disconnecting the copper pipe connecting the refrigerant radiator and the refrigerant system, so the components behind the first electric control cabinet 32 ​​are difficult to maintain, so the components that do not require maintenance or are not easily damaged can be designed at the rear side of the first electric control cabinet 32. The second electrical components with less serious heating are concentrated in the second electric control cabinet 33, and the heat dissipation is carried out by air cooling fans; the second electric control cabinet 33 is designed as a flippable electric control cabinet, which is designed to flip up, flip down, flip left, and flip right according to the application scenario, and the hanging structure and the first fastener 351 are used to realize the rapid disassembly and assembly of the second electric control cabinet 33, so that the first components at the rear side of the second electric control cabinet 33 are conveniently maintained, so the components that need maintenance or are easily damaged can be designed at the rear side of the second electric control cabinet 33.

[0089] The module board 321 for controlling the cooling fan generates serious heat during operation, so it is arranged in the first electric control cabinet 32 ​​and uses refrigerant to dissipate heat; the main control board 331 for controlling the operation of the energy storage temperature control device and the frequency conversion board 332 for controlling the operation of the circulating pump 27 of the coolant system do not generate serious heat during operation, so they are arranged in the second electric control cabinet 33 and use air cooling to dissipate heat.

[0090] The sensors, control valves, and connections between the components of the coolant system (water system) of the energy storage temperature control equipment are all in the form of threads, clamps, clamps, etc., which do not require hot work welding and can be disassembled without hot work, so they can be repaired and maintained with tools at the inspection port. The components in the coolant system that need maintenance or are easily damaged are set on the back side of the second electric control cabinet 33. The exhaust valve 14 and the injection / discharge port are not on the back side of the second electric control cabinet 33 (the exhaust needs to be designed at the highest point), and a separate inspection port is opened.

[0091] The components of the refrigerant system (fluorine system) of the energy storage temperature control equipment need to be disassembled without hot work. Generally, hot work is not allowed in the installation scene, so the unit needs to be disassembled and repaired in a specific maintenance place. Figure 8 The device (as shown in the rectangular frame Q5) can be disassembled and repaired at the inspection port.
