A unit in which the heat from one fluid (liquid or gas) is transferred to another. It usually takes the form of a bank of tubes carrying one (the primary) fluid flows. In the case of steam generators used in a PWR, both fluids are water, with the primary fluid circulating round the reactor and the secondary fluid circulating as steam through the turbine.
A heat exchanger is a plant, which transfers the thermal energy from one medium to another. Heat exchangers are very often used to utilize idle energy, e.g. of an exhaust gas, for pre-heating of combustion air and thus achieve a higher efficiency. In other cases, a circulating (radioactive) medium is not to leave the circuit and the energy is transferred to a medium harmless for further processing. Mostly tube or plate heat exchangers are used, whereat the heat transfer from one medium to the other takes place by means of heat conduction via the separating plate/tube walls.
A device to rapidly cool wort. Usually copper tubing that has cold water running through it. Sometimes 2 tubes, one inside the other, with wort going through one and cold water going through the other.
This is the "guts" of either means of heating your pond. Inside the RayPac Versa 155 there's a huge-bore stainles steel exchanger. It's fish safe no matter where you hold the TA and pH. It's also a $350 upgrade to the Versa which has a sticker price of about $1200 so it's pricey. The HydraTherm is nothing but a heat exchanger. It's full of tubes which carry the hot water from the boiler. There's a second pump which pumps water through the jacket around the tube array. The water passes by the tubes and picks up heat. The HydraTherms are all stainless construction. The silver ones are the 1999 design. The newer red ones are about the same price, and represent the 2000 upgrade with a jacket of red steel over a thick layer of insulation.
A mechanical system that allows the heat from outgoing exhaust air to be transferred to incoming fresh, air. This is achieved by constant fan-forced ventilation, using either flat-plate, or rotary exchangers.
usually considered to be that part of a furnace that transfers heat from burning fuel or electricity into air or other medium; also, it is any device in which heat is absorbed by one fluid from another fluid, such as a condenser, evaporator, or boiler
A device inside a boiler that transfers heat from the burning fuel to the boiler water. The hot water in the boiler is then circulated to radiators, indirect water heaters, hydro-air coils, radiant floor tubing, or other heat-distribution devices.
A piece of equipment used to transfer heat from one fluid (liquid or gas) to another or when two different types of liquid (water and oil) need to be heated. For example, when steam is used to heat air for space heating.
A component or components that transfers heat energy from one medium to another. For example heat could be transferred, in a geothermal heat pump system, from water-to-air or from water-to-water and visa versa.
A device, such as an automobile radiator, used to transfer heat from a fluid or gas on one side of a barrier to a fluid or gas on the other side without bringing the fluids or gases into direct contact.
This is a device for transferring heat energy from one medium to another. In a solar energy system as heated fluid or air from the collector passes through the heat exchanger, it transfers its heat load for immediate use or storage.
A device used to transfer hear from a fluid (liquid or gas) to another fluid, where the two fluids are physically separated (usually by metal tubing). Household examples of heat exchangers are heating radiators and the coils on your refrigerator and room air conditioner.
Heat exchange is the method by which the unwanted heat is removed from a system. A heat exchanger is a device by which energy (in the form of heat) is transferred from one fluid or gas to another across a solid surface.
This is a device that enables furnaces to transfer heat from combustion safely into breathable air. The primary heat exchanger transfers heat from combustion gases to the air blowing through the ductwork. It's vital that none of the combustion gas itself gets into the airstream. The primary heat exchanger handles the hottest gases. In high efficiency furnaces, secondary heat exchangers recover heat that used to be vented up the chimney with the exhaust gases. By recovering this heat, the furnace becomes more efficient. Part of the heat recovered here causes the water and acid to condense out of the exhaust gas. Because this liquid is corrosive, secondary heat exchangers must be designed to prevent deterioration. Usually this means they are made of stainless steel or some derivative of it.
A structure that transfers heat from one gas or liquid to another gas or liquid. For example, the hot combustion gases in a furnace to the circulating household air or, in a boiler, to the circulating hot water.
a device designed to transfer heat between two different materials (hot and cold liquid, liquid and air, liquid and soil, or hot and cold air) while maintaining a physical separation between the two materials.
a device in which heat is transferred by conduction through a metal barrier from a hotter liquid or gas, to warm a cooler liquid or gas on the other side of the metal barrier. Types of heat exchangers include "shell and tube," and "plate."
A device that transfers heat from one source to another. For example, there is a heat exchanger in your furnace - the propane flame and combustion products are contained inside the heat exchanger that is sealed from the inside area. Inside air is blown over the surface of the exchanger, where it is warmed and the blown through the ducting system for room heating. The combustion gases are vented to the outside air.
Technically, any equipment used for the indirect transfer of heat. Conventionally, a specific piece of equipment used to conserve energy by transferring heat from a process stream being cooled to one being heated.
device that passes heat from one substance to another; in a solar hot water heater, for example, the heat exchanger takes heat harvested by a fluid circulating through the solar panel and transfers it to domestic hot water.
Apparatus, which transfers heat from one fluid to another in cooling or heating systems. Air conditioners use both a condenser and an evaporator. Steam and hot water radiators are heat exchangers, which are used to produce heat.
A heat exchanger is a device built for efficient heat transfer from one fluid to another, whether the fluids are separated by a solid wall so that they never mix, or the fluids are directly contacted. They are widely used in refrigeration, air conditioning, space heating, electricity generation, and chemical processing. One common example of a heat exchanger is the radiator in a car, in which a hot engine-cooling fluid, like antifreeze, transfers heat to air flowing through the radiator.
