What is an example of a heat sink?
Types of the heat sink: It also depends on the air flow. The heat sink can be classified in to two categories: Active heat sink. Passive heat sink.
How many types of heat sinks are there?
The cooling system has four primary functions as follows: Remove excess heat from the engine, Maintain a constant engine operating temperature, Increase the temperature of a cold engine as quickly as possible, Provide a means for heater operation (warming the passenger compartment).
What are the 4 functions of a cooling system?
Fans are used for circulating air in rooms and buildings; for cooling motors and transmissions; for cooling and drying people, materials, or products; for exhausting dust and noxious fumes; for conveying light materials; for forced draft in steam boilers; and in heating, ventilating, and air-conditioning systems.
What is the function of a fan?
The cooling system is a set of components that enables the flow of liquid coolant to the passages in the engine block and head so as to absorb combustion heat. The heated fluid will then return to the radiator through a rubber hose, for cooling.
What is the cooling system?
A heat sink thus transfers the heat from the high temperature component such as a transistor to the low-temperature medium such as air, oil, water or any other suitable medium through conduction and then convection. There are two types of heat sinks, namely the passive heat sink and the active heat sink.
What are the 2 types of heat sink?
Folded heat sinks are built-up sheet metal, manufactured by folding sheet metal into a serpentine fin array. The folded sheets of metal are attached to the base of the heat sink by soldering or brazing, which results in an additional thermal resistance at that interface.
How are heat sinks made?
A heat sink is a device that absorbs heat generated by electronic components or chips. Among the different types of heat sinks, two-phase forced-convection cooling of high-heat-flux/high-power electronic devices is one of the most effective means of thermal management.
What is heat sink in electronics?
A heat sink is a component designed to enhance the heat dissipation from an electronic device. Generally, MOSFETs, IGBTs, and power ICs are the electronic devices in switch power supplies that need heat sinks attached to maintain a safe temperature. Usually a heat sink is composed of a base plate and fins.
What is the difference between a heat sink and the power supply?
Heat sinks are designed to maximize the surface area in contact with the coolant fluid. Aluminum alloys are the most common heat sink material. This is because aluminum costs less than copper. However copper is used where higher levels of thermal conductivity are needed.
What is the best material for a heatsink?
An ideal heat sink material exhibits high thermal conductivity, low coefficient of thermal expansion, low density, and low cost. Aluminium and copper are mainly used for laptop computer heat sinks. Aluminium is used where weight reduction is needed while copper is used when weight is not considered as a major factor.
