00:00.000 --> 00:06.430
Here is a Peltier effect module

00:06.430 --> 00:11.781
The delta t ° C, temperature difference of this module is 67 ° C

00:11.781 --> 00:22.855
This model sandwiches a Peltier module into a heatsink and a plate

00:22.855 --> 00:34.974
15 V 4 A maximum continuous: the direction of the current determines the hottest side

00:34.974 --> 00:50.401
By keeping the surface hot at room temperature via the aluminum heat exchanger

00:50.401 --> 00:59.742
Side heatsink low (if well sized) and 67 ° C from - opposite

00:59.742 --> 01:10.615
Theoretically one should go below 0 ° C on the cold side

01:10.615 --> 01:22.177
Before power on, laser measurement of temperature: 26.5 ° C

01:22.177 --> 01:32.923
A few seconds after switching on, already more than 19 ° C

01:32.923 --> 01:38.786
27 ° C on the hot

01:38.786 --> 01:43.272
12 ° C on the cold side, 30 ° C on the hot side after 30 s ...

01:43.272 --> 01:52.663
1 min. After total: 7.5 ° C

01:52.663 --> 02:04.001
Although the time of the aperitif is close one does not reach 0 ° C :-(!

02:04.001 --> 02:23.844
By reversing the direction of the current the cold side changes rapidly from -5 ° C to over 35 ° C!
