PIN FIN APPATATUS
: PSAW-604HT
The apparatus
consists of a channel in which the pin fin is tested in both natural as well as
forced convection. The channel is connected to the suction of blower. The
blower is operated to touch the pin fin in forced convection only. In natural
convection, the window above the pin fin is kept open to the atmosphere. Five
thermocouple tapings are given along the length of the fin. Thus the
temperature distribution along the length can be distinguished. Also natural
and forced heat transfer co-efficient, effectiveness, etc. can be found out.
Specifications:
1.Three pin
fins-
a) M. S.
b) Brass
c) Al
2.Channel- 150mm
x 100mm x 1000mm
3.Blower – run
by f.h.p. motor.
4.Orifice meter
along with water manometer to measure airflow.
5.Voltmeter and
ammeter to measure power input.
6.Cr- Al
thermocouple with 6 tapings along with temperature indicator.
7.Dimmerstat to
control power input.
8.A band heater
to heat the pin fin.
A technical
manual accompanies the unit.
Services required:
·
220v,
stabilized single phase supply along with earthing Connection.
· Floor area 2m x 1m x 1m height.
