Our company offers best quality Heat Pipe Demonstrator at the most competitive market price. These demonstrators are manufactured in compliance with the industry laid norms and parameters using finest quality metal. Owing to the corrosion resistance, easy installation, hassle-free operation and longer functional life, these demonstrators are extensively demanded around the globe.

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.

Experimentation:
  • To demonstrate the super thermal conductivity 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 time response of pipes.
  • To plot the temperature distribution along the length of pipes

Utilities required:
  • Electricity Supply: 1 Phase, 220 V AC, 4 Amp.
  • Table for set-up support.

Technical Specifications:
  • Pipes1ST: Heat pipe made of stainless steel
  • Pipes 2ND: Made of copper
  • Pipes 3 RD: Made of Stainless steel
  • Instruction Manual: An English instruction manual will be provided along with the Apparatus
  • Variac: 0-230 V, 4 Amp.

TypeMeasurement Apparatus

Owing to our expertise and domain knowledge, we have been able to offer Emissivity Measurement Apparatus at an industry leading price. This apparatus is precisely manufactured under the supervision of expert professionals using best quality raw material. Appreciated for easy installation, simple functionality and hassle-free operation, this apparatus is hugely demanded by the clients.

Description:
  • The present Set-up is designed to measure the emissivity of test plate. The test plate comprises of a mica heater sandwiched between two circular plates.
  • Black plate is identical with test plate, but its surface is blackened.
  • As all the physical properties, dimension and temperature are equal heat losses from both plates will be same except radiation loss.
  • Hence the input difference will be due to difference in emissivity.
  • Both plates are supported on individual brackets in a enclosure with one side glass to ensure steady atmospheric conditions.
  • Temperature Sensors are provided to measure the temperature of each plate and surrounding.
  • Electric Supply is given to heaters through separate variacs so that temperatures of both can be kept equal and is me asured with Digital Voltmeter and Digital Ammeter.

Press Wood250 mm dia. & 12 mm thick
Cast Iron250 mm dia. & 20mm thick
Bakelite250 mm dia. & 15 mm thick
Variac0-230 V, 2Amp

The setup consists of a heater sandwiched between two sets of slabs. Three types of slabs are provided on either sides of heater, which forms a composite structure. Asmall hand press frame is provided to ensure the perfect contact between the slabs.A variac is provided for varying the input to the heater. Digital Voltmeter and Digital Ammeter display the heat input. Heat produced by heater flows axially on both the sides.
