CROSS FLOW HEAT EXCHANGER

Bench top apparatus with a control and instrument unit for studies into the principles and performance of heat exchangers.

For comprehensive studies into the principles and performance of heat exchangers. The equipment allows students to quickly assess heat transfer rates by forced convection. They monitor the rate of cooling of a body of known thermal capacity in an air flow. Learn about CROSS FLOW HEAT EXCHANGER manufacturers for optimal educational outcomes.. The apparatus is bench mounting. It is a horizontal wind tunnel with a contraction cone, a working section, a diffuser, a constant speed fan, and an exhaust with silencer. Learn about CROSS FLOW HEAT EXCHANGER exporters for optimal educational outcomes.. A variable slide valve controls the air flow. The working section includes a series of rods arranged in a matrix and at right-angles to the direction of air flow. Learn about CROSS FLOW HEAT EXCHANGER suppliers for optimal educational outcomes.. To do experiments, students can remove any one of these rods and replace it with a cylindrical copper element. The copper element is of known thermal capacity and includes a built-in thermocouple. Learn about CROSS FLOW HEAT EXCHANGER specifications for optimal educational outcomes.. Students insert the element, which has been pre-heated to a specific temperature, into the working section at a known air velocity. They measure the time taken for the temperature to drop and determine the heat transfer rate. Learn about CROSS FLOW HEAT EXCHANGER thermodynamics India for optimal educational outcomes..
