TEC and water cooling for camera

Based on the suggestion by J. Kubera in Canada, an external cooling for DSLR is built.

3″ x 2 ” aluminum angle (6063) is modified so that the verical face (3″ high) could have a good contact with the camera LCD screen and the bottom face (2″) with the camera bottom. See the extra plate tightened to the vertical face with 4 bolts. The CPU-Heat Sink paste is used to eliminate the air-gap.

The TEC element and the water jacket, glued by the manufacturer, is also tightened with a plate and 4 bolts.

The camera is pushed against the extra plate with the bottom 1/4″ bolt and, at the top area, with fishing line with hook and a spring.

A CPU fan and Silica Gel beads in a plastic box is put on top of the camera.

The thermometer shows the temperature on the top corner of the aluminum angle (on the LCD screen side).
