Description

Technical Field

[0001] This utility model belongs to the field of circulation device technology, and more specifically, it relates to an indirect coolant circulation device with adaptive flow regulation function. Background Technology

[0002] Sodium-ion batteries, as a highly promising type of rechargeable battery, operate on a similar principle to lithium-ion batteries, primarily relying on the movement of sodium ions between the positive and negative electrodes to achieve charging and discharging. Due to their abundant resources, low cost, and high safety, they show broad application prospects in large-scale energy storage and electric vehicles. However, sodium-ion batteries generate a large amount of heat during charging and discharging. If this heat cannot be dissipated effectively and in a timely manner, the battery temperature will continue to rise, leading to decreased battery performance, shortened lifespan, and even safety hazards. Therefore, an efficient battery cooling system is crucial for the stable operation and performance improvement of sodium-ion batteries. Among various battery cooling methods, coolant circulation cooling is favored for its efficient heat dissipation capacity and good temperature uniformity. In this type of cooling system, the coolant circulation device is the core component. Its operation typically relies on an electronic water pump to deliver the coolant, and the flow rate is adaptively adjusted in conjunction with the thermostat.

[0003] Based on existing technology, it has been found that existing coolant circulation devices have some shortcomings:

[0004] First, the components of the cooling circulation device are assembled by splicing, and the outer shells of each component are fixedly connected by bolts. This assembly structure makes it very inconvenient to disassemble the outer shells when disassembling and repairing the components later.

[0005] Secondly, the components of the cooling circulation device are connected in series by connecting pipes. After the connecting pipes are fitted onto the interfaces of each component, they must be tied and fixed with wire to prevent them from loosening. This fixing method is not only inefficient to install, but also not conducive to disassembly later. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model relates to an indirect coolant circulation device with adaptive flow regulation function. This solves the problem that existing cooling circulation devices are assembled by piecing together components, and the outer casings of each component are fixed with bolts. This assembly structure makes disassembly and repair of the components extremely inconvenient. Furthermore, the components of the cooling circulation device are connected in series via connecting pipes. After the connecting pipes are fitted onto the interfaces of each component, they must be secured with wire to prevent them from loosening. This fixing method not only has low installation efficiency but also hinders subsequent disassembly operations.

[0007] In a first aspect, this utility model provides an indirect coolant circulation device with adaptive flow regulation function, achieved by the following specific technical means:

[0008] An indirect coolant circulation device with adaptive flow regulation function includes:

[0009] An electronic water pump and a thermostat are provided; the outer end of the electronic water pump is provided with interface A; the outer side of the thermostat is provided with interface B; connectors are fixedly installed on interface A and interface B, and the connectors on the electronic water pump and the thermostat can be connected through the connecting pipes fitted on their exteriors; a fixing component is fitted at the joint of the outer shells of the electronic water pump and the thermostat, and the gasket and pressure rod on the inner side of the fixing component are in contact with the outer shells of the electronic water pump and the thermostat.

[0010] Furthermore, the connector has a wedge-shaped structure inside, a thread inside, and a through-type adjustment window on its side.

[0011] Furthermore, the connector has an inner tube inside, and a flexible connecting tube can be fitted onto the inner tube.

[0012] Furthermore, a movable ring is installed inside the connector via a thread, and flexible claws are provided at equal intervals on the outside of the movable ring. When the claws move along the wedge-shaped structure inside the connector, they can bend inward.

[0013] Furthermore, rubber gaskets are symmetrically arranged on both sides of the inside of the fastener.

[0014] Furthermore, double-ended lead screws are rotatably mounted at both ends of the fixing component, and pressure rods are symmetrically slidably mounted on both sides inside the fixing component, with the pressure rods threadedly connected to the double-ended lead screws.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this device, by setting a fixing component and a rubber gasket on the inner side of the fixing component, the gap between the fixing component and the outer shell can be eliminated when fixing the outer shell, thus achieving initial fixation. Then, the double-ended screw drives the pressure rod to quickly clamp the joint between the electronic water pump and the thermostat outer shell. This double fixing method not only improves assembly but also effectively ensures the fixing effect at the joint of the outer shell. Compared with the traditional bolt fixing method, there is no need to repeatedly disassemble the bolts with additional tools, which greatly simplifies the disassembly and assembly process of the outer shell, making the subsequent maintenance operation of the components more convenient and efficient, and significantly reducing maintenance costs.

[0017] 2. In this device, by setting a connector with a wedge structure, a movable ring and a clamp, the connecting tube is fitted onto the inner tube. Rotating the movable ring causes the clamp to bend along the wedge structure and clamp the connecting tube, eliminating the need for cumbersome wire binding operations and effectively improving the efficiency of connection and fixation. At the same time, rotating the movable ring in the opposite direction releases the clamp from the clamp, making it easy to disassemble and replace the connecting tube later, thus solving the operational pain points of traditional fixing methods.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: As shown in the attached document Figure 1 To be continued Figure 4 As shown:

[0034] This utility model provides an indirect coolant circulation device with adaptive flow regulation function, including: an electronic water pump 1 and a thermostat 2; the outer end of the electronic water pump 1 is provided with an interface A101; the outer side of the thermostat 2 is provided with an interface B201; a connector 3 is fixedly installed on the interface A101 and the interface B201, and the connector 3 on the electronic water pump 1 and the thermostat 2 can be connected through the connecting pipe 3021 fitted on its outer side; a fixing member 4 is fitted on the splice of the outer shell of the electronic water pump 1 and the thermostat 2, and the gasket 401 and the pressure rod 4021 on the inner side of the fixing member 4 are in contact with the outer shell of the electronic water pump 1 and the thermostat 2.

[0035] As a second embodiment of this application, based on embodiment 1, such as Figure 4 As shown, the connector 3 has a wedge-shaped structure inside and a thread inside, and a through-type adjustment window 301 on the side end of the connector 3; the connector 3 has an inner tube 302 inside, and a flexible connecting tube 3021 can be fitted onto the inner tube 302; a movable ring 303 is installed inside the connector 3 by threads, and flexible claws 3031 are equidistantly provided on the outside of the movable ring 303. When the claws 3031 move along the wedge-shaped structure inside the connector 3, they can bend inward; the connector 3 facilitates the fixing of the components installed on the electronic water pump 1 or the thermostat 2. The connector 3021 includes an adjustment window 301 through which the movable ring 303 can be adjusted within the connector 3; an inner tube 302 is provided, through which the connector 3021 can be fitted onto the connector 3; the connector 3021 can be used to transport coolant between various components; the movable ring 303 is provided, and by moving the movable ring 303, the bending of the clamp 3031 can be controlled; the clamp 3031 can be used to fix the connector 3021 fitted onto the inner tube 302.

[0036] This application achieves clamping and fixing of the connecting pipe 3021 by fitting the connector 3 onto the interface of the electronic water pump 1 or the thermostat 2 and then fitting the connecting pipe 3021 into the inner tube 302 of the connector 3 when it is necessary to use the connecting pipe 3021 to transport coolant to the device. Then, the movable ring 303 is rotated to make the claw 3031 move along the wedge-shaped structure on the inner side of the connector 3 and bend.

[0037] As a third embodiment of this application, based on embodiment 1, such as Figure 3 As shown, rubber gaskets 401 are symmetrically arranged on both sides of the inside of the fixing part 4; double-ended screws 402 are rotatably installed at both ends of the fixing part 4; pressure rods 4021 are symmetrically slidably installed on both sides of the inside of the fixing part 4, and the pressure rods 4021 are threadedly connected to the double-ended screws 402; the fixing part 4 is provided to seal and fix the splice on the housing of the electronic water pump 1 or the thermostat 2; the gaskets 401 can eliminate the gap between the fixing part 4 and the housing when the fixing part 4 is fitted onto the electronic water pump 1 or the thermostat 2; the double-ended screws 402 can control the movement of the pressure rods 4021 within the fixing part 4; the pressure rods 4021 can be used to press against the housing of the electronic water pump 1 or the thermostat 2 to fix the housing.

[0038] This application achieves double fixation of the housing of the electronic water pump 1 or the thermostat 2 by fitting the fastener 4 onto the housing of the electronic water pump 1 or the thermostat 2 and placing the gasket 401 against the outside of the housing at both ends. The two housings are then tightly fitted together by rotating the double-ended screw 402, which causes the pressure rod 4021 to tighten and fix the two housings.

[0039] The specific usage and function of this embodiment are as follows:

[0040] In this utility model, such as Figures 1 to 4As shown, the outer shells of the electronic water pump 1 and the thermostat 2 are fixed at the joint using the fastener 4. Rotating the double-ended lead screw 402 causes the pressure rod 4021 to move within the fastener 4, pressing it against the outer shell. This, combined with the gasket 401, eliminates gaps and achieves a stable fit. The connecting pipe 3021 is then fitted onto the inner tube 302 of the connecting piece 3 of each component in the cooling circulation device. Rotating the movable ring 303 causes the claw 3031 to move along the wedge-shaped structure inside the connecting piece 3 and bend inward, thus firmly clamping and fixing the connecting pipe 3021, ensuring no leakage of coolant during transport. When the sodium-ion battery begins to charge and discharge, generating heat, the electronic water pump 1 is activated. The electronic water pump 1 delivers coolant to the connecting pipe 3021 through interface A101, cooling the... The coolant flows along the connecting pipe 3021 and enters the thermostat 2 through the interface B201. The thermostat 2 adaptively adjusts the coolant flow rate according to the real-time temperature of the sodium-ion battery. If the battery temperature is high, the thermostat 2 increases the coolant flow rate so that more coolant can flow through the cooling channels around the battery to absorb the heat generated by the battery. If the battery temperature is low, the thermostat 2 decreases the coolant flow rate to avoid overcooling and affecting battery performance. The coolant that has absorbed heat continues to circulate under the action of the electric water pump 1 and flows back to the electric water pump 1 through the connecting pipe 3021 to complete one cooling cycle. Repeating the cooling cycle can continuously and effectively remove the heat generated by the sodium-ion battery and maintain the battery within a suitable operating temperature range.
