Abstract

A technique to provide uniform temperature distribution within an incubator is disclosed. The technique employs micro heat pipes, which transfer heat from higher temperature region to lower temperature region in the incubator. As a result, uniform temperature is maintained in the incubator, which eliminates cold spots. The micro heat pipes are incorporated in the incubator for homogenizing temperature in the incubator. The micro heat pipe works as a heat sink and transfers heat from hot zone to the cold zone or cold spot of the incubator. The micro heat pipe provides optimal circulation of hot air in the cold spot.

MICRO HEAT PIPES IN INCUBATOR TO MITIGATE CONDENSATION ISSUE

BACKGROUND

The present invention relates generally to an incubator and more particularly to a technique to provide uniform temperature distribution within an incubator.

Generally, ambient temperature and humidity is increased to sufficiently high levels in an incubator. Such high levels of temperature and humidity are required inside an incubator for survival and well being of neonates. Pathogenic microorganisms also grow in such warm and humid environments in the incubator. Typically, microorganisms grow most robustly on cold spots in the incubator, where relative humidity is sufficiently high to sustain microbial growth.

Neonatal incubators lack optimal circulation of hot air in the cold spot. Heat is not transferred from hot areas of the incubators to the cold spot. As a result, moisture or liquid is collected at the cold spot, which provides ambient environment for microbial, typically, bacterial growth.

Therefore, it would be desirable to have a technique to provide homogenous temperature distribution within an incubator.

DETAILED DESCRIPTION

A technique to provide uniform temperature distribution within an incubator is disclosed. The technique employs micro heat pipes, which transfer heat from higher temperature region to lower temperature region in the incubator. As a result, uniform temperature is maintained in the incubator, which eliminates cold spots. The micro heat tube is generally incorporated in systems where there is an obstruction for air flow.

Micro heat pipe is a small metal pipe with a capillary structure (wick) on an inner wall of the pipe. The micro heat pipe has a vacuum inside the tube. A small quantity of working fluid is present in the tube. When a section of the micro heat pipe is heated, the heat is quickly transferred to a lower temperature section of the micro heat pipe in the following way. Initially, the working fluid is heated by absorp...
