technical field

The invention relates to a liquid metal battery incubator with an air-cooled heat dissipation mechanism and a heat dissipation method thereof.

Background technique

Liquid metal batteries are a new type of low-cost, high-efficiency, and long-life energy storage battery technology, which has a good application prospect in large-scale energy storage in power grids. The large-capacity energy storage system composed of liquid metal batteries can adjust the peak of the power grid, load the peak and fill the valley, effectively enhance the operation stability of wind power generation and solar power generation systems, and improve the power quality.

Liquid metal batteries are high-temperature batteries. The long-term operating temperature is generally 400-600°C. The working temperature for short-term heating or formation needs to reach 700°C. Therefore, the battery operation needs to have a heating and heat preservation device, and the maximum design temperature of the incubator for stable operation is 700°C. It is also necessary to ensure that the maximum temperature difference in the incubator is less than 20°C during the working process of the incubator. The reported incubators are generally used in sodium-sulfur batteries, the maximum temperature is only 350°C, and the maximum temperature difference in the incubator is controlled to 30°C, such as the special incubator for sodium-sulfur batteries (application number: CN201010584548.7), a sodium-sulfur battery Battery module incubator (application number: CN201410106677.3), etc. There are few reported incubators specifically for liquid metal batteries, and the part about the incubator in a liquid metal battery module for kilowatt-level power storage facilities (application number: CN201510514549.7) only introduces the use of electric heating tubes to heat To supplement the heat required by the system, aluminum silicate ceramic fiber is used as the material of the insulation layer. Neither the layout position and form of the electric heating tubes, nor the temperature range that can be controlled, nor the selection of the thickness of the insulation layer and the number of layers A description of a setting, implementation, or calculation. An incubator design for liquid metal batteries and liquid metal battery kilowatt-level modules (application number: CN201410777993.3), the heating part relies on the Joule heat of the battery pack itself and the heating partition between the battery packs in the box to maintain Temperature is a multi-layer heating design, but there are some defects. First of all, the wiring of the interlayer battery pack is connected through the side, and the space utilization rate is low; secondly, the patent (application number: CN201410777993.3) emphasizes that the Joule heat of the battery itself maintains the heat supply of the incubator system under high current discharge, It may be feasible for several kilowatt-level modular incubators, but it is difficult to achieve complete self-heating of the battery pack under normal working conditions for large-scale energy storage incubators of 10 kilowatts, 100 kilowatts, megawatts and above. Especially in the initial heating stage, it is difficult to achieve heating to the target temperature; finally, this patent (application number: CN201410777993.3) pays less attention to the heating design of the partition, and does not disclose the heating method and The installation and layout of the heating device, and the lack of separate temperature control and monitoring devices for each layer of the sub-cavity structure, largely limits the expansion of the liquid metal battery module. Some of the company's previous patents on liquid metal battery incubators (application numbers: CN201610920571.6 and CN201611209114.2) mainly focused on heating, heat preservation and temperature control design, without considering active heat dissipation and rapid cooling control.

Compared with the incubator for sodium-sulfur batteries, this patent can achieve higher heating temperature and more uniform control temperature; CN201611209114.2), this patent focuses on the temperature control of the incubator, especially the cooling and shutdown control, and a plurality of temperature measuring thermocouples are installed in the incubator cavity for temperature control or monitoring, the temperature control circuit of the heating wire and The temperature measuring thermocouples in the cavity are connected to the battery management system (BMS). In addition, this patent emphasizes the realization of available functions through heating and heat preservation, and at the same time puts more emphasis on later shutdown and cooling maintenance, so as to better deal with the application of energy storage battery packs under complex working conditions, and ensure the temperature of the temperature field and the working efficiency of the complex working conditions. safety.
