We are one of the Best Cooler Suppliers in India. Heat can be reduced by using an air cooler. You may use the addition of cooling fins to the surface of an object as an example of the first. Either by including them in the design of the product or by firmly fastening them to its surface (to ensure efficient heat transfer). In the latter instance, a fan is used to blow air into or onto the object that needs to be cooled in order to cool it.
