Evaporative cooling system

Abstract

The invention relates to a technique for cooling various products, which is based on the effect of heat release, wherein the system is adaptable to multiple platforms and is transportable. The cooling system is composed of: an inner body (1), a sponge material (2), a fabric shield (3) ensuring impermeability, an outer body (4) that provides protection, fans (5) which are mounted on the outer body, grooves (6), and pipes (7) for conveying water to the sponge. This system is environmentally friendly, as it uses neither refrigerant gases nor chemical products. In addition, it consumes only small amounts of water and electricity, regardless of weather conditions.

Description

[0001] Description

[0002] 1) Field of the invention:

[0003] This invention relates to the field of manufacturing, thermal storage, distribution and sale of products. The invention consists of a cooling system adaptable to several platforms and which can be transportable.

[0004] 2) State of the prior art:

[0005] In our daily lives, the need to cool drinks during the day is very noticeable, especially in spring and summer, whether it is for employees in companies or students and teachers in schools and universities. Moreover, there are serious health problems due to cooling systems, whether for consumables or for the transport of certain medications. Generally, the latter require a temperature lower than room temperature (minus 25°C for suppositories, suppositories, creams and insulin, and minus 8°C for vaccines), which is not respected by all carriers.

[0006] There are also traditional coolers, but they do not meet the needs of customers "because they do not maintain the same temperature throughout the day."

[0007] There are also electric coolers but they are expensive (starting at $70).

[0008] The domestic refrigeration system is also another solution. It consists of several components (expansion valves, motors, compressors, etc.), and it consumes a lot of electrical energy, therefore, it cannot be operated with batteries. However, the latter are also heavy, so they cannot be transported in a cooler. In addition, the components used in the domestic refrigeration system are very expensive.

[0009] This prompted us to think about a practical solution to all these problems, which is where the idea for this invention comes from. 3) Detailed description of the invention:

[0010] To overcome all the disadvantages mentioned below, we propose a transportable cooling system (Figure 1) which is based on fans which are very economical and which can operate for a long period thanks to the use of batteries (Figure X).

[0011] Our system is inspired by the natural phenomenon "evaporative cooling", which is a physical phenomenon based on the evaporation of a liquid that absorbs much more heat than the amount required to increase its temperature by a few degrees.

[0012] Our invention consists of using a material that absorbs moisture through a sprinkler system (Figure 5) so that it is always moist, a semi-permeable fabric (3) that allows the vapor to escape and fans (5) to force or suck in ambient air through the heat exchange section.

[0013] The advantages and particularity of this system are: reduced system cost and evaporation is 100%.

[0014] The cooling system (Figure 2) consists of the following parts:

[0015] - The inner body (1) is the wall which will contain the objects to be cooled, totally isolated from the external environment.

[0016] - The sponge material (2) is the element that will be wet in order to carry out evaporation, and it is in direct contact with the inner body (1).

[0017] - The role of the Power Shield (3) is to ensure impermeability to water and at the same time permeability to steam which will release heat during evaporation.

[0018] - The outer body (4) ensures the protection of all these elements against dust and the effects of the external environment.

[0019] - The fans (5) are attached to the outer body to circulate the air inside the cooler and force the evaporation of water (Figure 3). - The three grooves (6) are used to escape the air in order to have a better air circulation (Figure 3).

[0020] - The pipes (7) pass the water towards the sponge to ensure that it remains permanently moist.

[0021] The accessories or instruments of our system are: a tank, a pump, a valve, pipes, injectors, a humidity and temperature sensor and a temperature sensor.

[0022] - Sensors: For our system, we will need two sensors: a humidity and temperature sensor and another temperature only sensor. For the humidity and temperature sensor, there are generally two types: DHT11 and DHT22. The latter are more efficient and give values ​​in decimal and more precise (temperatures varying from -40°C to 80°C and a humidity percentage from 0% to 100%), it is for this reason that we propose these sensors for the manufacture of our patent. As for the temperature and humidity sensors, there are several types of temperature sensors, we propose to manufacture it with thermistors. These sensors are made of a semiconducting metal oxide material encapsulated in a small epoxy or glass bead. They function as resistors, and it is the variation of this resistance with temperature that allows us to measure the degree of heat in an environment.They are very sensitive and generally have very high nominal resistance values ​​(from 2000 to 10000 Q).

[0023] - A Tank: Volume in Liters.

[0024] - A Pump: Flow rate in L / h; Pressure in MPA; Power in Watts.

[0025] - A Valve: Diameter.

[0026] The role of the latter is to communicate the moisturizing liquid (Water) with all parts of the fabric around the inner wall. (Figure 2) The reservoir (1) and the pump (2) must be installed in the lid to gain surface area around the cooler. The humidity sensor (6) is installed in the fabric, when it detects that the fabric is dry, the valve (3) opens and the pump (2) starts, therefore it circulates the water in the pipes (4) to the injectors (5) which make the fabric wet, (Figure 4) Brief description of the drawings
