Abstract

A thermal architecture for a single door incubator is disclosed. The thermal architecture comprises a centrifugal fan and heating coils arranged on an incubator bed platform. The architecture also includes a lower duct in which the fan and the heating coils are placed. The fan and the heating coils are arranged radially with respect to each other. Advantageously, the thermal architecture is simple and provides uniform heat distribution in the incubator bed.

THERMAL ARCHITECTURE OF A SINGLE DOOR INCUBATOR

BACKGROUND

 

The present disclosure relates generally to incubators and more particularly to thermal architecture of a single door incubator.

Generally, incubators are used for thermoregulation of a closed environment of a baby. As depicted in Figure 1, temperature in the incubator is typically maintained using convective heat transfer. In many instances, thermoregulatory unit of the incubator comprises a filter, a fan, a heater, ducts and a canopy (or dome shown in Figure 1). The fan sucks fresh air and sends the air to the heater, where the air picks up heat. The heated air traverses through the ducts and reaches the canopy.

Subsequently, the air is re-circulated with help of another fan between the canopy and area near the heater. Thereby, the re-circulated air is continuously heated by the heater forming a cycle for thermoregulation.

Figure 1

Various incubators employ various conventional thermoregulation techniques including coil based heater with axial fan, heat sink based heater with axial centrifugal fan, coil based heater with forward curved centrifugal fan, heat sink based heater with backward curved centrifugal fan. However, these conventional thermoregulation techniques do not provide uniform distribution of heat in incubator bed.

It would be desirable to have an improved thermal architecture for uniform distribution of heat in the incubator bed.

BRIEF DESCRIPTION OF DRAWINGS

Figure 1 depicts thermoregulation technique based on convective heat transfer used in a conventional incubator.

Figure 2 depicts the thermal architecture for a single door incubator comprising a centrifugal fan and heating coils arranged on an incubator bed platform.

Figure 3 depicts air getting sucked through air intake path by a fan.

Figure 4 depicts a backward curved centrifugal fan placed with the heating coils on both sides.
