Embodiment Construction

[0134] It should be appreciated from the foregoing that embodiments of the present invention rely on one of the well-known anomalous properties of some fluids, such as water: namely, that their density is greatest at a critical temperature. The temperature coefficient of thermal expansion of the fluid is positive above the critical temperature and negative below the critical temperature. This phenomenon is shown in figure 1 , where the density of water is plotted as a function of temperature. The critical temperature of water can be considered to be approximately 4°C. Reference will be made herein to water as an example of a fluid that may be used in some embodiments, but it is understood that other fluids having similar properties with respect to the temperature coefficient of thermal expansion may also be useful. A fluid comprising water and one or more additives may be useful (such as water and salt). Salt can allow the critical temperature to be lowered. Other additive...

Abstract

The invention discloses a cooling device (100) comprising: a fluid storage tank (130) for holding a fluid to be cooled, the storage tank (130) having a top region (130H) and a body region ( 130B), each of the top region (130H) and the body region (130B) are configured to contain a fluid to be cooled; and a heat exchange portion. In use the apparatus is configured to allow cooling means to cool fluid in the top region (130H), wherein the fluid reservoir (130) is arranged such that the cross-sectional area of ​​the reservoir (130) is between the top region (130H) and the At least a portion of the distance of the body region (130B) is tapered as a function of the distance from the top region (130H) to the body region (130B).

Description

technical field [0001] The invention relates to a refrigeration device. In particular, but not exclusively, the invention relates to a refrigeration device for storing and transporting vaccines, perishable food, packaged beverages, etc., and for cooling or controlling the temperature of devices such as batteries when a reliable power source is not available . Aspects of the invention relate to devices and methods. Background technique [0002] A large portion of the world's population does not have access to a continuous and reliable supply of mains electricity. Underdeveloped countries, or areas far from populated areas, are frequently subject to rationing of electricity, often by means of "zonal blackouts", which are caused by deliberate blackouts or failures of distribution networks. [0003] Storing vaccines, food and beverages at appropriate temperatures is difficult in such regions without a constant and / or reliable power supply, limiting the widespread use of conve...
