Solution Approach 1:

The patent introduces an intermediary device (temperature control system with heating element, circulation pump, and temperature sensor) between the cold source and the liquid cooling vest. This intermediary system mediates the temperature control process by circulating liquid, adjusting its temperature, and controlling the flow rate, thereby preventing direct thermal exchange that causes rapid cold loss while maintaining effective cooling.

Inventive Principle:

Solution Approach 1:

The patent implements a feedback control system using a temperature sensor to continuously monitor the liquid temperature and a control unit to adjust the heating element and circulation pump accordingly. This feedback mechanism prevents extreme temperature differences by dynamically adjusting the liquid temperature and flow rate, thereby reducing environmental heat exchange losses while maintaining effective cooling power.
