Heat Exchangers

A heat exchanger is a device designed to efficiently transfer or “exchange” heat from one matter to another. When a fluid is used to transfer heat, the fluid could be a liquid, such as water or oil, or could be moving air. The most well-known type of heat exchanger is a car radiator. In a radiator, a solution of water and ethylene glycol, also known as antifreeze, transfers heat from the engine to the radiator and then from the radiator to the ambient air flowing through it. This process helps to keep a car’s engine from overheating.

There are various types of heat exchangers:

1- Air-to-liquid cooling

2- Liquid-to-air cooling

3- Liquid-to-liquid cooling

4- Air-to-air cooling

Auto A/C Evaporator

An evaporator is used in an air-conditioning system to allow a compressed cooling chemical. Evaporator performance is essential for proper air-conditioning performance.

Available Evaporator Types:

1- Multitank Super-slim (MS)
2- Parallel Flow single-tank
3- Laminate
4- Serpentine
5- Fin & Tube (mostly used in refrigerators (HVACR))

Auto A/C Condenser

The condenser functions as a heat exchanger. It releases heat into the air passing through its fins. The refrigerant system releases heat energy with a condenser and receives heat energy with the evaporator. The condenser receives high temperature high pressure vapor from the compressor and converts it to high pressure liquid through the process of condensation. It is located in front of the radiator and constructed of tubes surrounded by cooling fins. As air passes through the tubes and fins, the heat in the refrigerant is passed through the condenser fins and into the atmosphere. The condenser releases the heat absorbed from the cabin by the refrigerant in the evaporator. The purpose of the condenser is to release heat and change the state of the refrigerant from vapor to liquid.

Types of available A/C condensers:
1- Parallel Flow Condenser (PFC)
2- Serpentine Condenser
3- Fin & Tube (mostly used in residential and commercial heat exchangers)

Parallel flow condensers are much more efficient than serpentine condensers. The problem is, when a parallel flow unit gets clogged, what we call ‘restricted’, it can be impossible to clean.

Auto A/C Heater

This device gives you the ability to dictate what comes out of your vehicle’s A/C and heater system. With this device in place, you can adjust the temperature inside your vehicle to help counter the current temperature outside your ride. This allows you and your passengers to stay comfortable regardless of the weather outside .

Auto A/C Charge Air Cooler (CAC)

In turbocharged engine applications, the air used for the engine combustion is compressed in order to increase its density. Ultimately, this makes the combustion more efficient resulting in better engine performance and lower exhaust emissions.

Passenger Car Aluminum Radiators

A radiator is a heat exchanger that uses coolant to dissipate excess heat from the engine. Radiator performance is essential for proper engine cooling and function. Our radiator configurations, tanks, fin pitch, core dimensions and materials meet OE manufacturer’s rigid standards.

Radiator types:

Plastic tank with aluminum core

Plastic tank with copper core

Cross-flow and down-flow configurations

Illustration Details:

1- Fin Pitch – Superior fin waves provide a higher heat transfer.

2- Flow Configuration – Available in cross-flow and down-flow configurations.

3- Aluminum or Copper Core – Thin-tube construction assures maximum cooling efficiency.

Copper & Brass Radiators

Despite the fact that aluminum radiators are commonplace these days and more cars are produced with them due to advantages such as lighter weight, more corrosion resistance, cheapness, etc., however copper & brass radiators are still used in older models of cars and are especially recommended for heavy duty vehicles such as trucks, buses, tractors and other agricultural and road-making vehicles.
Ravimex International can supply you with a wide range of models of copper & brass radiators with OEM and A.M quality at competitive prices. For more information, please contact us.

Refrigerator Compressor

The compressors are one of the most important parts of the refrigeration cycle. The compressor compresses the refrigerant, which flows to the condenser, where it gets cooled. It then moves to the expansion valve, and the evaporator and it is finally sucked by the compressor again. For the proper functioning of the refrigeration cycle, the refrigerant must be compressed to the pressure corresponding to the saturation temperature higher than the temperature of the naturally available air or water. It is the crucial function that is performed by the compressor. Compression of the refrigerant to the suitable pressure ensures its proper condensation and circulation throughout the cycle. The capacity of the refrigeration or air conditioning depends entirely on the capacity of the compressor.

Refrigerator Evaporator

It is in the evaporators where the actual cooling effect takes place in the refrigeration and the air conditioning systems. The evaporators are heat exchanger surfaces that transfer the heat from the substance to be cooled to the refrigerant, thus removing the heat from the substance. In the domestic refrigerators the evaporators are commonly known as the freezers since the ice is made in these compartments. Nowadays, the most common evaporator used in refrigerators and freezers is fin & tube type.

Roll Bond Evaporator

A roll bond evaporator is roll-formed after being designed/printed on aluminum plates as per customers’ requirements or drawings.
It has been widely used as evaporator in a refrigerator or freezer, which space for evaporator installation is normally very compact and in hence high heat transfer coefficient and compact design is essential.
