Description

Technical Field

[0001] This utility model relates to the field of liquid cooling system technology, specifically a highly integrated and efficient intelligent temperature-controlled liquid cooling system. Background Technology

[0002] In system integration, the installation space for electrical, busbar, and fire protection components is extremely limited. Multiple components compete for space, leading to structural interference or insufficient insulation distance. Heat dissipation in the electrical compartment is difficult, as it integrates heat-generating devices such as fuses, circuit breakers, and busbars. The system operates at kiloamperes, generating high heat. Currently, external air conditioning is typically used for cooling. During factory production, reverse or incorrect connection of the busbars can easily occur, causing rework or safety risks. The system relies on the unit's liquid temperature to heat the battery cells, which is slow and consumes a lot of power. Meanwhile, the high-voltage box or electrical components also need to dissipate heat. Currently, water fire protection systems have external interfaces, requiring external water pipes to be connected in case of danger. Utility Model Content

[0003] The purpose of this invention is to provide a highly integrated and efficient intelligent temperature-controlled liquid cooling system to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a highly integrated and efficient intelligent temperature-controlled liquid cooling system, comprising a container body, wherein the container body is divided into a battery compartment and an electrical compartment, wherein a liquid cooling unit, a pump-type fire protection and power distribution communication unit are fixedly installed in the electrical compartment, wherein a number of battery packs and pipelines are installed in the battery compartment, wherein the liquid cooling unit is connected to a convergence area through pipelines, and the convergence area includes a convergence integration component;

[0005] The busbar assembly is equipped with a stack-level busbar on top. One end of the stack-level busbar is connected to the high-voltage box. The end of the stack-level busbar away from the high-voltage box is equipped with a fuse and a switch. The switch has an external output port and an external output port on one side. The busbar assembly is made of injection molding material. The busbar assembly has a pre-embedded flow channel, which forms a main inlet and main outlet circuit for the high-voltage box.

[0006] Preferably, the pipeline includes three stages: primary, secondary, and tertiary, each containing inlet and outlet water pipelines, and the pipeline is equipped with a bidirectional shut-off valve.

[0007] Preferably, the liquid cooling unit has four operating modes: cooling, heating, self-circulation, and standby, and is a frequency converter.

[0008] Preferably, the stack-level busbar is divided into stack-level busbar positive, stack-level busbar negative, cluster-level busbar positive, and cluster-level busbar negative, and the cluster-level busbar positive and cluster-level busbar negative are plugged into the high-voltage box.

[0009] Preferably, the interior of the high-voltage box is filled with coolant, the high-voltage box is connected to two battery clusters, and the back of the high-voltage box integrates a guide structure, a water flow connection port, and an electrical connection female connector.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: by integrating the stack-level busbar and electrical components onto the busbar assembly, heat dissipation is achieved through pre-embedded channels, reducing the volume occupied. Each stack-level busbar and pipe is separated by pre-embedded channels, which can isolate temperature. The liquid in the pre-embedded channels acts as a container barrier to prevent the spread of disaster. When the disaster expands, the liquid in the pre-embedded channels is used for initial water fire suppression to inhibit the spread and buy time for personnel to respond. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] Please refer to 1-4 for one embodiment of this utility model: a highly integrated and efficient intelligent temperature-controlled liquid cooling system, including a container body 1. The container body 1 is divided into a battery compartment and an electrical compartment. The electrical compartment is equipped with a liquid cooling unit 2, a pump-type fire extinguishing system 3, and a power distribution and communication unit 4. The battery compartment is equipped with several battery packs 5 and pipelines. The liquid cooling unit 2 is connected to a convergence area through pipelines. The convergence area includes a convergence integration component 6. The electrical compartment utilizes the saved space to integrate the pump-type fire extinguishing system 3, which can spray multiple times in the event of thermal runaway, effectively suppressing the spread of thermal runaway. It can also integrate EMS and other devices, possessing dynamic energy response capabilities.

[0018] A stack-level busbar 7 is provided above the busbar assembly 6. One end of the stack-level busbar 7 is connected to the high-voltage box 8. A fuse 12 and a switch 11 are provided at the end of the stack-level busbar 7 away from the high-voltage box 8. A positive output port 10 and a negative output port 9 are provided on one side of the switch 11. The busbar assembly 6 is made of injection molding material. The busbar assembly 6 has a pre-embedded flow channel. The pre-embedded flow channel forms the main inlet and main outlet circuit for the high-voltage box 8, which serves as the main inlet and main outlet circuit for the coolant on the side of the high-voltage box 8, replacing the original pipeline method. The busbar assembly 6 has reserved installation positions for electrical components and pipelines.

[0019] During system operation, on the battery side, a compressor-type liquid cooler is used to dissipate heat from the battery. The high-voltage box 8 and the busbar assembly 6 use a dry cooler for heat exchange, while water flow from the high-voltage box 8 side is used to exchange heat with the electrical components and the stack-level busbar copper busbar 7.

[0020] Under low-temperature heating conditions, the liquid cooling channel on the battery side and the liquid cooling channel on the high-voltage box 8 side are connected by a solenoid valve. Normally, they are separated. In low-temperature environments, at level 1, they are connected and there is no cooling. The pump group on the high-voltage box 8 side runs, transferring the heat from the high-voltage box 8 and the manifold to the coolant, and then heating the battery. At level 2, the heat from the high-voltage box 8 and the battery heating unit simultaneously heat the battery, increasing the heating rate.

[0021] Under static insulation conditions, based on ambient temperature and operating condition predictions, the dry-cooling unit stops cooling in advance and uses the liquid in the pre-embedded flow channel for heat storage, storing the energy generated by the high-pressure box 8 during this stage in the coolant. During the system's static period, when the battery triggers a heating demand, this coolant is prioritized for heating and insulation of the battery. For low-temperature projects, this avoids the need for the unit to operate in heating mode. It also reduces auxiliary power consumption and improves the overall system output efficiency.

[0022] During normal operation, if the coolant on the battery side is insufficient, the liquid can be transferred from the cavity of the busbar assembly 6, reducing the frequency and difficulty of system maintenance.

[0023] In the event of thermal runaway or other anomalies, the fire suppression components will activate first. The liquid in the six chambers of the manifold can act as a container partition to prevent spread. When the disaster escalates, the liquid in the six chambers of the manifold can be used for initial water fire suppression to inhibit the spread and buy time for personnel to respond.

[0024] The pipeline system consists of three levels: primary, secondary, and tertiary, each containing inlet and outlet water pipes, and equipped with bidirectional shut-off valves.

[0025] The working modes of the liquid chiller unit 2 include four modes: cooling, heating, self-circulation, and standby. It is a variable frequency device. The liquid chiller unit 2 provides a cold source for two parts. One part is the compressor for cooling, which provides coolant for the battery compartment. It can operate at a lower or higher frequency according to the input. The other part is the dry cooler, which exchanges heat with the coolant flowing through it through a heat exchanger to cool the high-pressure box 8 and the manifold 6.

[0026] The stack-level busbar 7 is divided into stack-level busbar positive, stack-level busbar negative, cluster-level busbar positive and cluster-level busbar negative. The cluster-level busbar positive and cluster-level busbar negative are connected to the high-voltage box 8.

[0027] The interior of the high-voltage box 8 is filled with coolant. The high-voltage box 8 is connected to two clusters of batteries. The back of the high-voltage box 8 integrates a guide structure, a water flow connection port, and a back plug female connector for electrical connection. During installation, personnel only need to push the high-voltage box 8 into place in the forward direction to complete the connection of external flow without manual intervention. The front face of the container is for waterway and end communication connection.
