Abstract

The present invention can be designed by applying a scientific principle of specific heat and insulation with a semiconductor element which is a very small frozen element capable of refrigeration. If a small freezer for an ice bar or frozen food is made, a burden of eating an ice bar at one time before the ice bar melts can be removed, and the ice bar can be stored anytime and anywhere without restriction and can be eaten in case of necessity. For mobility and portability, a study of a solar cell and a secondary cell may be more necessary so as to stably supply power. According to the present invention, even though normal power supply, a solar cell, and computer USB power supply can be all used, a charging effect of sunlight is actually very weak. Moreover, a low temperature can be continuously maintained by more reinforcing convection current and a heat conduction effect with an internal fan.

Description

{Small Freezer for Frozen Food}

Small refrigerator, Peltier device, food storage box.

The main uses of Peltier devices are as follows. Climate control sheets in automobiles, chillers in semiconductor fields, circulators, cooling plates and chucks, blood analyzers in medical instruments, PCR, sample temperature cycle testers, chemical circulators, dehumidifiers, spectrophotometers, optics CCD cooling, infrared sensor cooling, laser diode cooling, photodiode cooling, SHG laser cooling, computer CPU cooling, chip set burning, and other refrigeration boxes, small refrigerators, coolers, wine refrigerators, rice cookers, It is used for industrial waste heat generators, remote power generation and so on.

The principle of the cool mat is a gel which is a heat-absorbing cool feeling material. According to the advertisement, the body absorbs heat quickly when it reaches the temperature, and the gel moves and releases heat through continuous flipping. That is, the cooling gel maintains a proper temperature through endothermic and exothermic heat.

Endothermic reaction: A reaction in which the energy of the reactant is relatively small and the energy of the product is large, so that the reaction must absorb heat energy from the surroundings in order to proceed.

- exothermic reaction: the energy of the reacted substances is greater than the energy of the generated substances, so that the energy corresponding to the difference is released to the outside. Combustion reaction, and neutralization reaction at room temperature.

- Gel: A substance in which the colloidal particles in solution lose fluidity and solidify to a solid or semi-solid state with some elasticity and firmness.

- Forms and examples of gels: Colloidal particles are in the form of a solid mesh with each other, and the space is filled with liquid. Agar, gelatin, tofu, and protoplasm of an organism.

- specific heat: the amount of heat required to raise the temperature 1 ° C or 1K of a substance 1g.

- Non-heating formula: If a substance with a mass of m (g) has a temperature change of ΔT (° C) when it is supplied with a quantity of Q (cal), the specific heat of this substance is obtained by the following formula.

C = Q / m? T (cal / g 占 폚)

- Method of measuring specific heat: The specific heat of an object is measured using the formula of calorie Q = cm Δt and (calories lost by a hot object) = (calories from a low temperature object).

- Heat conduction: the phenomenon that heat energy is continuously transferred from a high-temperature material to a low-temperature material even though the movement of the material is not lost. It occurs mainly in the interior of solid bodies, and in the case of conductors, heat is transferred faster. Liquids and gases have a very slow thermal conductivity compared to solids and it is difficult to diffuse the heat applied to some of them. The speed of conduction varies greatly depending on the type of material.

- Cooling system: A device to prevent the cylinder from overheating due to the high temperature in the internal combustion engine. It is largely classified into air-cooled type and water-cooled type. In the case of the air-cooled type, there is a cooling pin around the cylinder, which dissipates some of the temperature in the cylinder into the atmosphere. Cooling action is less than water-cooled type, so it is not used other than small-sized engine. In the case of the water-cooled type, water jacket, radiator, fan, thermostat, etc. are installed around the cylinder. The structure is somewhat more complicated than the air-cooled type, but it is widely used in internal combustion engine cooling systems because of its much better cooling effect

- Cooling element: also called Peltier element, Thermoelectric element, Phelz element, Summer module. It is a device that absorbs heat in one junction and dissipates heat in the other junction when electricity is supplied to both junctions of two systems in which two different metals are bonded to each other. Heat is transferred from the heat-absorbing surface to the heat-dissipating surface through the thermoelectric element and the heat transferred is proportional to the voltage supplied.

- Use of cooling device: In semiconductor field, it is used in circulator, cooling plate and chuck, blood analyzer in medical instrument, PCR, spectrophotometer, infrared sensor cooling, CPU cooling in computer, chip set burning, Refrigerator, cold / hot water machine, wine refrigerator, rice bottle, small kimchi refrigerator, dehumidifier, industrial waste heat generator and remote power generation.

It is said that many food poisoning occur in summer. Cooling food slows the growth of germs, so we want to make a small portable refrigerator that can always be carried. I was interested in a small-sized refrigeration device used to cool computer CPUs made by my sister. It is very convenient if it can make it very small by combining this freezing element and the fan, and I think it will be easier to keep it when I eat ice cream.

The name of the hairbrush is a material that uses a phenomenon called a thermoelectric element to cool it, and by using this, an aluminum cooling plate is attached to the opposite side of the cooling element to make a freezer of a size that allows ice cream to enter. The freezer is small, light and portable, and it can keep the food cool by attaching the solar cell and without changing the battery.

By using a semiconductor device capable of a very small refrigeration device called a refrigeration device, it was possible to design a barber luxury product by applying the scientific principle of specific heat and insulation. There are many products using this material, but there is not yet a device to freeze ice bars or small food. It is an ultra-high-volume aluminum cold plate and solar portable mini-refrigerator that maintains cold ice cream for a long time only with insulation technology

1 shows an embodiment of the present invention

If these small ice creams and food freezers are made, there will be no burden of having to consume all of the ice bars before melting them at once, and there is an advantage that they can be stored at any time without restriction and can be eaten as needed. For this mobility and portability, further study of solar battery or rechargeable battery will be needed to supply power steadily. Although the present invention was designed to use both a conventional power source and a solar computer computer USB power source, the charging effect of sunlight was actually very weak.

In addition, the internal convection and convection effects of the fan must be further strengthened to maintain the low temperature.
