Constant temperature chamber

Abstract

A constant temperature chamber includes a cavity, a first fan, and a second fan. The cavity includes a first side, a second side, a third side, and a fourth side. The first and second sides are oriented towards each other in a first direction. The third and fourth sides are oriented towards each other in a second direction which is different from the first direction. The first side defines a plurality of first vents, the second side defines a plurality of second vents, the third side defines a plurality of third vents, and the fourth side defines a plurality of fourth vents. The first fan includes a first air inlet and a first air outlet. The first air inlet is in communication with one of the first or second vents. The first air outlet is in communication with the other one of first or second vents. The second fan includes a second air inlet and a second air outlet. The second air inlet is in communication with one of the third or fourth vents. The second air outlet is in communication with the other one of third or fourth vents.
