actually there is no difference , infact condenser itself is a heat exchanger
A heat exchanger is a device that transfers heat from one fluid to the others. A condenser is simply a heat exchanger. It compresses refrigerants into a hot gas to then condense them into a liquid. Majorly condenser is used to cool the required vapor and heat exchanger is used to heat the required liquid.
Surface condenser is a heat exchanger in which latent heat only absorbed by the cooling media and heat exchange mostly takes place on availble just surface of the tube bundle. Overhead condenses is also a heat exchanger in which latent heat and somewhat sensible heat also removed from the fluid
Both the cooler and heat exchanger perform the same function as they remove heat from the engine. Two popular types of coolers are air-to-air inter-coolers that allow air to flow over fins and air-to-water models. The heat exchanger is often mounted in front of the radiator and uses airflow to reduce water temperature.
There is only one condenser. That would be an air condenser.

Calorifer is a heat exchanger, with a specific of air (or other gas) preheat. Usually is directly in a Duct installed. Heat Exchanger usually is separate unit.
difference between cooler and heat exchangers
A condenser boiler has a primary and a secondary heat exchanger. Fuel that is used to simply warm up water can be sent to the secondary heat exchanger and reused. This is a substantially more efficient use of energy.
A condenser is a form of heat exchanger. In the condenser, the coolant condenses from a gas to a liquid, and loses heat energy to the surroundings (like air being blown across it).
A heat exchanger with straight tubes in a shell that can normally be mechanically cleaned
Heat is absorbed by the refrigerant liquid inside the fridge, and rejected by the heat exchanger on the back of it.
there are two type of heat exchanger in absorption refrigeration, first is liquid heat exchanger and other is gas heat exchanger.both heat exchanger function is same, to transfer heat (hot medium to cold medium) without violate second newton law of thermodynamics. liquids heat exchanger is between boiler and absorber vessel mean while gas heat exchanger between evaporator and absorber.
Similar function to a car radiator or an air conditioning condenser. The heat from the fluid is pressurized to build up heat. As it passes through the heat exchanger, the heat from the heated fluid is exhanged to the ambient air which passes through the cooling fins.
double pipe heat exchanger is made if two concentric tubes one carrying cold flow and the other one carrying hot flow. but shell and tube hear exchangers are made of a shell like a vessel filled with many thin tubes to transfer heat between fluids. there are more data available at : http://scopewe.com/double-pipe-heat-exchanger-design-part-1/
The use of the LMTD arises straightforwardly from the analysis of a heat exchanger with constant flow rate and fluid thermal properties. It is a simple method to approximated the temperature diving force in a heat exchanger. The LMTD is a logarithmic average of the temperature difference between the hot and cold streams at each end of the exchanger. The larger the LMTD, the more heat is transferred.
