HEAT PIPE DEMONSTRATOR MAKE:-CREATIVE LAB MODEL NO: - CLHT-03
DESCRIPTION:

It is a super-conducting device and involves the transfer of heat by boiling and condensation of a fluid and hence transfer of heat takes place under nearly isothermal condition.  In this apparatus the comparison of heat pipe with the copper pipe as good conductor of heat and with the stainless steel pipe as same material of construction is made. It consists of three identical cylindrical conductors in respect of geometry.  One end of these is heated electrically while there are small capacity tanks acting as heat sinks at the other end.  The unit consists of a heat pipe, a copper pipe and a stainless steel pipe.  The performance of the heat pipe as a super-conducting device can be studied well in terms of the temperature distribution along the length at a given instant and can be compared with other two members.  Nearly isothermal temperature distribution and fast rise of temperature in heat sink tank reveals the heat pipe superiority over the conventional conductors.

HEAT TRANSFER FROM A PIN-FIN MAKE: CREATIVE LAB MODEL NO:-CLHT-04
 DESCRIPTION:                                                              
The setup is designed to study the heat transfer in a pin fin. It consists of pin type fin fitted in a duct. A fan is provided on one side of duct to conduct experiments under forced draft conditions. Air flow rates can be varied. A heater heats one end of fin and heat flows to another end.  Heat input to the heater is given through Variac. Digital voltmeter and digital ammeter are provided for heat measurement. Digital Temperature Indicator measures temperature distribution along the fin.

HEAT TRANSFER IN AGITATED VESSEL MAKE: CREATIVE LAB MODEL NO:-CLHT-05
 DESCRIPTION:

In most industrial processes including reactors, heat is to be added or extracted to control the process. The addition and removal of heat is done by passing steam or water in a jacket fitted to the outside of the vessel or passing steam or cold water in helical coil inside the vessel. For effective heat transfer and even distribution of heat, the liquid inside is continuously agitated. The present set-up offers us a comparative study of Jacket & Helical coil, which can be operated simultaneously. It is a stainless steel jacketed vessel with helical coil of copper is fitted inside. A variable speed stirrer is fitted in the vessel. Variation in temperature of inside water is measured and is noted. Set-up is fitted with steam traps for condensate collection. Flow rate of water can be controlled and measured using valve and Rotameter. Temperature of inlet and outlet of both hot & cold fluids are measured by temperature sensors.
