A primary heat exchanger converts solar energy into useful heat and uses a heat-transport fluid flowing through it to transfer the heat. The different types of solar collectors include flat-plate collectors, evacuated tube collectors, and compound parabolic concentrators, among others. While the flat- plate and the evacuated tube collectors are ...
When the fluid is hot, it goes to the solar heat exchanger to transfer its thermal energy to the secondary circuit without mixing. The liquid of the secondary circuit is regular water that can be stored in an insulated tank. Sometimes, hot water is used to harness a solar water heating system or in a climatized swimming pool.
Solar thermal energy can be used both to supply thermal energy in a heating system and solar thermal power plants. Other examples of standard heat exchangers are the car radiator and the heater for domestic heating. A heat exchanger is a device designed to transfer heat between two media that are separated by a barrier or that are in contact.
The heating is done by geothermal water at 170°C at a flow rate of 3 kg/s. The inner tube has a diameter of 1.5 cm. The overall coefficient of heat transfer of the heat exchanger is 640 W/m 2 K. Implementing the effectiveness NTU method, calculate the length of the heat exchanger.
In this way, solar heating can be used (1) to heat the circulating water molecules, (2) direct heating of backup heating system, and (3) instant heating of swimming pools. The “absorber” is the heart of solar collector and usually composed of large number of narrow metal strips.
The stored solar radiations are transferred to the houses of different areas, by means of conduction, convection, and radiation. In some regions, small fans, and larger air blowers are used to distribute the heat. The process of conduction takes place by the transfer of heat energy, in between the two objects, in direct contact with each other.
The plates of this type of heat exchanger are very long and thickness of passage between the plates must be rather small so that after the sheets forming the upper and lower surfaces are welded together, the unit can be wrapped into a spiral form. That’s why it is called as a spiral heat exchanger.

Heat exchanger. Typically, solar panels work by transferring heat from the collector to the tank through a separate circuit and a heat exchanger. Heat collected by the panel heats up water (or oil or another fluid) that flows through a circuit of pipes into a copper coil inside your hot-water tank. The heat is then passed into the hot water ...
