HEAT PIPE DEMONSTRATOR APPARATUS

About HEAT PIPE DEMONSTRATOR APPARATUS

Specification:

HEAT PIPE DEMONSTRATOR APPARATUS

It is a super-conducting device andinvolves the transfer of heat by boiling and condensation of a fluid and hencetransfer of heat takes place under nearly isothermal condition.

In this apparatus the comparison ofheat pipe with the copper pipe as good conductor of heat and with the stainlesssteel pipe as same material of construction is made.

It consists of three identicalcylindrical conductors in respect of geometry.

One end of these is heatedelectrically while there are small capacity tanks acting as heat sinks at theother end. The unit consists of a heat pipe, a copper pipe and a stainlesssteel pipe.

The performance of the heat pipe as asuper-conducting device can be studied well in terms of the temperaturedistribution along the length at a given instant and can be compared with othertwo members.

Nearly isothermal temperaturedistribution and fast rise of temperature in heat sink tank reveals the heatpipe superiority over the conventional conductors.

Experimentation

To demonstrate the super thermalconductivity of Heat Pipe and to compare its working with best conductor i.e.Copper pipe & Stainless-steel pipe as same material of construction.

To plot the temperature v/s timeresponse of pipes.

To plot the temperature distributionalong the length of pipes
