Technical Problem

[0004]鉴于以上现有技术的不足之处，本发明提供了一种户外储电设备用自适应双向热调控箱体，以解决传统户外储电设备箱体难以同时兼顾高温环境下的有效散热与低温环境下的主动保温、且现有热管理方式依赖外部供电、结构复杂、适应性差等技术问题

Benefits of technology

[0022] This invention relates to an adaptive bidirectional thermal control enclosure for outdoor energy storage devices. It innovatively incorporates a passive insulation unit on the top or side walls and an active control unit on the bottom wall, comprising a thermoelectric conversion module and a shaped composite phase change material electric heating module. By utilizing the synergistic effect of the passive insulation unit and the active control unit, an asymmetric thermal management path with controlled heat transfer is constructed within the enclosure. This not only reduces heat transfer from the outside to the enclosure in high-temperature environments, but also utilizes the temperature difference between the inside and outside of the enclosure to drive the thermoelectric conversion module for thermoelectric cooling. Combined with the phase change endothermic effect of the shaped composite phase change material, heat inside the enclosure is absorbed, conducted, and released gradually, effectively suppressing the temperature rise of the energy storage module. Furthermore, in low-temperature environments, the temperature difference between the inside and outside of the enclosure drives the thermoelectric conversion module to generate electricity, which is then transmitted to the electric heating module to heat the shaped composite phase change material, causing it to continuously release heat to the energy storage module, maintaining a suitable operating temperature inside the enclosure. This achieves both active heating and low-temperature insulation of the energy storage module.

Abstract

The application discloses an outdoor energy storage equipment self-adaptive bidirectional heat regulation box body, which comprises a box body, a passive heat insulation unit and an active regulation unit. The box body has a top wall, a side wall and a bottom wall, and an accommodating cavity for accommodating an energy storage module is formed inside. The passive heat insulation unit is arranged on at least the top wall or the side wall, and is used for reducing the transmission of external heat to the accommodating cavity. The active regulation unit comprises a thermoelectric conversion module and an electric heating module made of a shaped composite phase change material. The electric heating module is arranged on the bottom wall and is in thermal contact with the energy storage module. The passive heat insulation unit and the active regulation unit work together to construct an asymmetric heat management path inside the accommodating cavity, and realize self-adaptive bidirectional heat management in an outdoor environment. The application can not only effectively inhibit the transmission of external heat to the inside of the box body and actively reduce the temperature in the box in a high-temperature environment, but also actively heat and insulate the energy storage module in a low-temperature environment, so as to realize all-weather self-adaptive heat management without external power supply.
