Abstract

A culture apparatus includes a heat insulating box main body having an inner box; a culture vessel; a duct and a circulation blower forcing convection of a gas in the culture vessel; a humidifying pan disposed on the bottom of the culture vessel and positioned inside the duct; a heat pipe having a heat insulating section, a heat input section disposed at one end of the heat insulating section and a heat dissipation section disposed at the other end of the heat insulating section. The heat pipe is attached to the culture apparatus with the heat dissipation section being disposed outside the culture apparatus, the heat insulating section passing through the heat insulating box main body and the inner box, and the heat input section being disposed in a gas passage in the duct.

First claim

What is claimed is:

1. A culture apparatus comprising:
a heat insulating box;
a culture vessel provided in the heat insulating box for culturing cultures;
a humidifying pan disposed on a bottom of the culture vessel, the humidifying pan configured to store water for controlling humidity inside the culture vessel; and
a heat pipe including a portion passing through a side wall of the heat insulating box and a heat dissipation portion disposed outside the culture apparatus,
wherein a distal end of the heat pipe inside the culture vessel is positioned below the portion of the heat pipe passing through the heat insulating box, and the distal end of the heat pipe is positioned above an inside of the humidifying pan,
whereby water condensed on the heat pipe inside the culture vessel drops from the distal end of the heat pipe into the inside of the humidifying pan.

2. The culture apparatus according to claim 1 , wherein the heat pipe inside the culture vessel comprises a portion being parallel to the side wall.

3. The culture apparatus according to claim 1 , wherein the heat pipe inside the culture vessel is bent downward at a bending portion such that a portion between the distal end and the bending portion is parallel to the side wall.

4. The culture apparatus according to claim 1 , further comprising: a heat insulating sealing member interposed between the portion of the heat pipe passing through the heat insulating box and an interior surface of the heat insulating box.

5. The culture apparatus according to claim 1 , wherein the heat pipe comprises a sealed vessel, a metal rod, or heat sink.

6. The culture apparatus according to claim 5 , wherein the metal rod is made of copper, aluminum or silver.
