The Grashof baby incubator operates on the principles of natural convection and natural circulation to maintain a constant temperature required by premature babies experiencing hypothermia. Here’s an explanation of its working principle:
- Natural Convection:
- Definition: Natural convection is a process where heat is transferred through a fluid (air in this case) due to density differences caused by temperature variations.
- Application in Grashof Incubator: The Grashof Incubator utilizes natural convection to create a flow of air within the incubator chamber. Warm air tends to rise because it is lighter than cold air, creating a natural circulation of air.
- Natural Circulation:
- Definition: Natural circulation is the movement of a fluid (air) without the use of any external means like pumps. It occurs due to the density differences in the fluid caused by temperature variations.
- Application in Grashof Incubator: The incubator is designed to facilitate natural circulation of air. As the warm air rises, it displaces cooler air, which then moves downward. This creates a continuous loop or circulation of air within the incubator.
- Heat and Mass Balance:
- Definition: Heat balance refers to the equilibrium between the heat produced and the heat lost within a system. Mass balance involves the conservation of mass within the system.
- Application in Grashof Incubator: The natural convection and circulation within the incubator contribute to a balanced heat and mass distribution. The system is designed to ensure that the heat generated within the incubator is sufficient to counteract heat losses and maintain a constant temperature.
- Maintaining Constant Temperature:
- Thermostatic Control: The Grashof Incubator is likely equipped with a thermostat that monitors the temperature within the incubator. When the temperature deviates from the desired constant level, the thermostat activates the heating elements to restore the balance.
- Benefits for Premature Babies:
- The unique design of the Grashof Incubator ensures that premature babies are kept in a stable and controlled environment, preventing hypothermia.
- The natural convection and circulation system contribute to the efficient and uniform distribution of heat within the incubator, creating an optimal environment for the well-being of premature infants.
In summary, the Grashof Incubator employs natural convection and circulation to establish a balanced heat and mass distribution, maintaining a constant temperature required for premature babies. The design is aimed at providing an effective and energy-efficient solution for addressing the needs of infants from low-income families across Indonesia.

The importance of maintaining a constant temperature for premature babies experiencing hypothermia.
Maintaining a constant temperature is crucial for premature babies experiencing hypothermia due to their unique vulnerabilities and challenges in regulating body temperature. Here’s a brief introduction to the importance of temperature control in the care of premature infants:
- Underdeveloped Thermoregulation:
- Premature babies, born before completing a full-term gestation, often have underdeveloped thermoregulation systems. Their bodies struggle to generate and retain heat, making them highly susceptible to hypothermia, a condition where the body loses heat faster than it can produce it.
- Limited Brown Fat Reserves:
- Brown fat is a specialized type of fat that plays a crucial role in thermogenesis (heat production). Premature infants have limited brown fat reserves, which are essential for maintaining body temperature. As a result, they are more reliant on external heat sources to stay warm.
- Increased Surface Area to Body Weight Ratio:
- Premature babies typically have a larger surface area relative to their body weight compared to full-term infants. This increased surface area makes them more prone to heat loss through radiation, convection, conduction, and evaporation.
- Vulnerability to Infections and Complications:
- Hypothermia in premature infants is associated with an increased risk of infections, respiratory distress, and other complications. Maintaining a constant and appropriate body temperature is essential for supporting the overall health and development of these vulnerable infants.
- Energy Conservation for Growth:
- Premature babies require a significant amount of energy for growth and development. When their bodies are expending energy to combat hypothermia, it can compromise essential physiological processes. Maintaining a constant temperature helps conserve energy for vital growth and development milestones.
- Neurological and Developmental Impact:
- Fluctuations in body temperature can have adverse effects on the neurological and developmental outcomes of premature infants. Consistent warmth provides a stable environment for optimal brain development and overall well-being.
- Role in Kangaroo Care and Bonding:
- Maintaining a constant temperature is essential for successful implementation of practices like Kangaroo Care, where the baby is placed against the parent’s skin. This close contact helps regulate the infant’s temperature, promotes bonding, and contributes to better health outcomes.
- Specialized Equipment and Incubators:
- Specialized equipment, such as incubators like the Grashof Incubator mentioned earlier, plays a crucial role in providing a controlled environment. These devices help regulate temperature, humidity, and air circulation, creating a protective space for premature infants.
The importance of maintaining a constant temperature for premature babies experiencing hypothermia cannot be overstated. It is a critical aspect of their care that directly influences their survival, health, and long-term developmental outcomes. Specialized medical equipment, along with attentive and precise temperature management, is fundamental in providing the best possible start for these vulnerable infants.

In Indonesia, since 2012, there has been a foundation that lends incubators for premature babies at home and this organization has a presence in 150 cities in Indonesia. For those who need help from the Indonesian Premature Baby Foundation in providing free services, please make a contact by sending a message via Whatsapp to WA Center 62-8111383300. Thousands of babies have been helped since 11 years ago. For further information please click www.inkubator-gratis.org
Starting from research at the Heat Transfer Laboratory, Faculty of Engineering, University of Indonesia, various types of Grashof Incubators have been developed. Among them are 1) Type A, namely the large type according to the scale of the hospital. 2) Type F, small portable type weighing only 13 kg. 3) Type H, namely a detachable incubator (knocked-down). 4) Type J, namely Twin-incubator for twin-babies… etc. This free home baby incubator lending system will continue to be developed for all cities in Indonesia. The target is that in the next 2-3 years, it can reach 300 cities. After that, it will continue with development to other countries around the equator (Equator belt countries).
