Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field especially is a kind of wearable temperature field monitoring self-starting radiator. BACKGROUND

[0002] In the field of clinical medicine and personal health management, body temperature regulation is one of the core needs of fever management. In traditional fever reduction methods, physical cooling methods are attracting attention due to their avoidance of drug side effects, but manual wiping or ice application, which relies on manual operation, has problems such as low efficiency, short duration, and discomfort. With the development of wearable technology, head-mounted cooling devices have become an important research direction by achieving continuous cooling through active heat exchange. However, traditional wearable cooling devices still face significant technical challenges in the design of air-cooled systems: first, the built-in power supply module, such as the battery and the drive circuit, generates parasitic heat during long-term operation, which is superimposed on the target cooling load, forming a heat management paradox that leads to increased system energy consumption and decreased cooling efficiency; second, the design of the cooling flow channel structure lacks fluid dynamics optimization, and traditional homogeneous flow channels are prone to induce turbulent vortices and fluid separation due to cross-section mutations or curvature mismatches, which not only increases air resistance and noise but also causes airflow energy loss, further weakening the efficiency of heat convection.
