Description

HEATING AND COOLING DEVICE AND METHOD USING PELTIER EFFECT

SEMICONDUCTOR

FIELD OF THE INVENTION

Embodiments of the present invention, generally relate to a semiconductor- based heating and cooling device and method, and more particularly to an device for thermal treatment of human injury or an animal injury, for providing cyclic heat treatment of hot therapy and cold therapy to the human injured part or the animal injured part.

BACKGROUND

Many injuries to the human body and animal bod (for example, bruised muscles, aching joints, damaged ligaments, and post-surgery recoveries) are treated with th application of hot and or cold therapy. Such therapies require the application of heat or removal of heat to the affected area of the human body, and help to reduce swelling, pain, and promote healing. In some injuries, cyclic heat treatment (i .e. , hot-cold-hot-cold or similar patterns) is also recommended as it offers better recovery and health benefits over that of constant heat or constant cold treatments. in the past, injuries requiring cold compresses have often been treated by a cloth, bandage or gel that has been cooled in a freezer and applied to the injured area. Ice packs have also been used to apply cooling therapy to a body surface. Injuries requiring heat treatment have often treated b a cloth or bandage that has been heated, and then applied to th Injured area.

However, these different past approaches have various shortcomings. For example, these conventional approaches require lot of preparation and he ce are inconvenient. For example, ice packs need to be frozen and stored in a freezer prior to application to an injury. Similarly, a hot water bottle requires it to be placed in boiling water to reach an effective hot temperature. Further, ice packs and heated cloths return to ambient temperature in a relatively short time. \

Further, there are some conventional devices also available, that uses heated or cooled water and circulates the water through tubes around the affected areas of the body to provide cyclic relief. However, these conventional devices are bulky, expensive, and have slow cycling times due to requirement of fluid changeover. Further, the conventional devices provide poor control over the temperatures and durations that these devices operate.

The concept of Peltier effect has been in existence for many years. Peltier coolers and the use of them to cool eiectronic elements and devices is also well known . However, typical arrangements of these include a plurality of thermal couples in contact with two planar elements. Thus, there Is a 'hot' plane and a 'cold' plane spatially removed therefrom. This system is invariably used in all Peltier configurations. In addition, the Peltier cooler and the device to be cooled are typically electrically isolated. That is, they are thermally coupled but are on different electronic circuits. The semiconductors are known to be mounted on ceramic substrate for thermal conductivity and insulation. While the concept is known, the elements used io implement the concept has limitations which prevent t eir efficient use.

Therefore,, there is a need for an improved system that utilizes the concept of Peltier effect more efficiently , and an improved device and a method for providing cold therapy and hot therapy to the user's injured part.
