Description

{Device for controlling water temperature}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a water temperature regulating device for a rearing water of a fish tank or a living fish tank using a Peltier element that generates heat and an endothermic reaction when a power source is supplied. In order to widen a surface area contacting with a fluid or air contacting with a Peltier element The present invention relates to an apparatus for regulating the temperature of a living fish in a living fish water tank in which heat exchange efficiency is improved by using a plurality of heat sinks.

The Peltier effect, which is a basic principle used in the present invention, is a phenomenon discovered by J.C.A.Peltier in France in 1834, and corresponds to one of the electrical properties according to the junction that is handled in the field of electronics and materials engineering. When current flows in a junction between two different materials, heat is generated and heat is absorbed. If heat is generated when the current flows in one direction, the heat is absorbed when the current flows in the opposite direction The property is called Peltier effect.

An example of application of the reversibility of the Peltier effect is a Peltier element in which an N-type semiconductor element and a P-type semiconductor element are connected by a metal plate. A thermoelectric element (Peltier element) or a thermoelectric module (TEM) Also.

When power is supplied to the Peltier device, a current is transferred to the N-type semiconductor device, and then a current flows through the connecting metal plate and the P-type semiconductor device to cause a heat generation phenomenon and an endothermic phenomenon to occur in the connection metal plate. When the current flows in the opposite direction, an endothermic phenomenon occurs and a heating phenomenon occurs in the connecting metal plate.

In general, the Peltier device can be easily installed in a refrigerator for storing cosmetics or medicines, which does not need to lower the refrigerating temperature to a very low level because no pollutant is generated at the time of disposal due to small capacity noiseless in addition to the heating and cooling function or in a narrow space Such as a small refrigerator or a portable refrigerator using a battery as a power source.

Peltier devices have a solid structure, so they are highly reliable and can be used semi-permanently. They can be cooled lower than ambient temperature (environment temperature), so if you have an appropriate control system, you can control the temperature more precisely than ± 0.05 ℃ (PID control) Recently, the frequency of development of techniques for applying Peltier elements to temperature control devices is increasing.

However, since the cost per unit is low, the efficiency of cooling the heat absorbing portion depends on the temperature of the heat generating portion having latent heat during the heat absorption, and it takes time to lower the temperature of the heat generating portion to an appropriate level, On the contrary, since it takes time to raise the temperature of the heat absorbing portion to an appropriate level during heating, the heating efficiency by the Peltier element is lowered. Therefore, it is urgent to develop a technique for improving the heat exchange efficiency of the Peltier element.

The water temperature regulating device includes a Peltier element having a function of warming or warming, a heat radiating plate which is in contact with the upper surface of the Peltier element, a chilling heat radiating plate which is in contact with the lower side surface of the Peltier element, Fan. Since the cooling structure of the heat absorbing part mounted inside the Peltier element depends on the temperature of the heat generating part, the heat sink has a function of lowering the temperature of the heat generating part to a proper level. do.

In the present invention, the heat radiating plate is separated from the heat radiating plate and the heat radiating plate on the upper and lower surfaces of the Peltier element, and the heat radiation of the Peltier element is designed to be diverged by heating and cooling.

The Peltier device for water temperature control according to the present invention comprises a heating heat sink having a plurality of comb teeth surfaces formed in contact with the upper surface of a Peltier element on the basis of a Peltier element having a function of warming or warming, And a cooling fan installed on the upper surface of the heat sink.

As shown in FIG. 2, the Peltier element designated for the purpose of warming or heating can be installed as a dual Peltier element by adjusting the scale of each component according to the application. In this case, each of the Peltier elements can perform different functions and can perform the same functions.

3 shows a perspective view of a Peltier element among Peltier devices for controlling water temperature according to the present invention. The operation principle of the Peltier element for temperature control is transferred to the N-type semiconductor element through the first contact metal plate formed inside the Peltier element when power is supplied to the Peltier element. Current flows to the second contact metal plate through the connecting metal plate and the P-type semiconductor element. At this time, heat dissipation occurs in the first and second contact metal plates, and the end plate is cooled as the endothermic phenomenon occurs.

If the flow of current is changed according to the reversible nature of the Peltier element, on the contrary, a heat absorption phenomenon occurs in the first and second contact metal plates and a heat dissipation phenomenon occurs in the connection metal plate. In general, a Peltier device has a function capable of both temperature sensing and heating, so that it is common to use a single Peltier device in one device.

However, when a single Peltier element performing a warming function is changed to a temperature-sensing function, a high temperature held inside the Peltier element to cause an endothermic reaction in a state of holding an already elevated temperature is lower than the temperature of the fluid as a heat absorbing object So that more time is required and the efficiency is lowered. In the opposite case, if a single Peltier element performing a temperature sensing function is changed to a warming function, it takes more time to generate a low temperature state of the Peltier element to be higher than the temperature of the fluid to be heated in order to cause an exothermic reaction in a low temperature state And the efficiency is lowered.

Therefore, in the present invention, the Peltier element designated for the warm or warm application is configured to perform only the respective functions. The Peltier element designated for the purpose of warming or heating is mounted as a water temperature regulating device to restore the reduced heat exchange efficiency at the time of function conversion of the Peltier element and to shorten the time required to maintain the water temperature at a constant temperature, .

The heat radiation plate includes a horizontal plate having a predetermined thickness and a pair of side plates protruding from the outer side of the horizontal plate so as to face each other, and a plurality of comb plates protruding vertically from the horizontal plate between the pair of side plates .

The heat radiation plate has a structure including a plurality of protruded combs, so that the heat dissipation area in contact with the air is increased. If the Peltier element installed to contact the lower part of the horizontal surface of the heating heat sink exhibits excessive heating, the heat radiation plate assists the heat radiation using the secured heat radiation area. If the Peltier element shows excessive cooling, To transfer the heat contained in the air or the heat sink to the Peltier element.

It is preferable that the heat sink is made of an aluminum material having a high thermal conductivity in order to increase heat exchange efficiency. It can be made of stainless steel or copper material, but it is not suitable because the product is heavy and may lead to an increase in unit price.

However, in the case of the warming or warming action, the fluid reaches the set temperature precisely.

On the other hand, in the second embodiment, the fluid passing time per hour is high and the same amount of fluid is passed in a short time.
