Cooling interventions are routinely implemented to protect brain cells in clinical scenarios such as hyperthermia, cerebral trauma, and post-craniocerebral surgery. Traditional cooling modalities include ice pack cooling, alcohol sponge baths, and conventional physical cooling. However, these methods present distinct limitations: ice pack cooling features unstable temperature control and requires frequent replacement; alcohol sponge baths involve cumbersome operation accompanied by a strong alcohol odor; and conventional physical cooling fails to achieve satisfactory cooling efficacy. These drawbacks collectively result in suboptimal therapeutic cooling effects.

At present, the thermoelectric cooling-based medical craniocerebral cooling cap has been extensively applied in clinical practice. It stands as one of the core therapeutic tools for rescuing patients with craniocerebral injury and elevated intracranial pressure induced by various etiologies, preventing and treating cerebral edema, facilitating postoperative recovery after neurosurgery, and managing hyperthermia, coma and heatstroke caused by diverse disorders. This apparatus can effectively reduce intracranial pressure and lower brain cell temperature, saving patients’ lives and accelerating rehabilitation. It is an ideal medical device for mild hypothermia neuroprotection in clinical departments including neurology, neurosurgery, intensive care unit (ICU), infectious diseases department, emergency department and pediatrics department.

The thermoelectric cooling medical craniocerebral cooling cap is composed of a cap body, heat-dissipation water circuit, thermoelectric cooling module, and water pump. Adopting thermoelectric cooling technology, it realizes cold water circulation across the entire cap structure through the built-in water channel system, thereby lowering the brain temperature of the wearer. This design significantly improves cooling efficiency, maintains constant cooling temperature, and shortens the overall cooling duration.

Thermoelectric cooling is a refrigeration approach based on the thermoelectric effect, also referred to as thermoelectric refrigeration or thermoelectric cooling. The fundamental component of a thermoelectric cooler is a thermocouple pair, which is formed by connecting one p-type semiconductor element and one n-type semiconductor element in series.

When a direct current (DC) power supply is connected, the current flows from the n-type to the p-type element at the upper junction, triggering a temperature drop and heat absorption to form the cold side; at the lower junction, the current flows from the p-type to the n-type element, causing a temperature rise and heat release to form the hot side. Multiple thermocouple pairs are connected in series to construct a standard thermopile. With the assistance of various heat transfer components, the hot side of the thermopile continuously dissipates heat to maintain a stable temperature, while the cold side absorbs heat in the working environment to generate a low-temperature environment. This constitutes the working principle of thermoelectric cooling.
