The thermostatic chamber 110 is a constituent means for providing a space for maintaining the constant temperature.

At this time, the thermostatic chamber 110 is formed as a cylindrical housing that can be opened and closed through a lid 111, and a receiving space 115 is formed therein, and a plurality of engaging steps 117 are protrudingly formed on the outer surface thereof.

Here, a temperature sensor 113 for detecting the internal temperature is installed in the accommodation space 115.

Meanwhile, the temperature regulator 120 is a constituent means for performing a heating action and an endothermic (cooling) action to maintain the internal temperature of the accommodation space 115 at a predetermined set temperature.

At this time, the temperature controlling part 120 is formed such that the first conductive pieces 121 are closely contacted to both sides of the outer surface of the thermostatic chamber 110 symmetrically with each other, and the first conductive pieces 124 have the seating grooves 122 And a thermoelectric element 123 is installed in the seating groove 122.

In addition, the first conductive piece 121 is formed in the latching groove 280 on one side thereof. The stopper groove 280 is formed with a locking step 117 of the thermostatic chamber 110 so that the thermostatic chamber 110 and the first conductive piece 121 have a rigid connection structure.

A second conductive piece 124 having a contact groove 125 is closely fixed to the other side of the thermoelectric element 123 and a heat dissipating piece 126 is provided in the contact groove 125. At this time, a plurality of radiating fins (127) protrude from the radiator (126). A case 128 having an insertion space 129 is provided on the other side surface of the heat dissipating piece 126 and is bolted to the first conductive piece 121 and the second conductive piece 124.

At this time, the radiating fins 127 of the radiator 126 are positioned in the insertion space 129.

The heat and cool air transferred to the second conductive piece 124 and the heat dissipating piece 126 move to the respective heat dissipating fins 127 and smoothly move along the high pressure air generated through the air blowing device 290 .

The case 128 is connected to an air injection pipe I for introducing high pressure air to the insertion space 129 at the upper end thereof and a high pressure air introduced into the insertion space 129 at the lower end thereof. And an air discharge pipe (O) for discharging is connected.

A spacing spacer 270 for separating the first conductive piece 121 from the case 128 is connected between the first conductive piece 121 and the case 128. The spacing spacer 270 prevents thermal interactions between the first conductive piece 121 and the case 128 to improve the thermal efficiency of the temperature regulator 120.

At this time, it is preferable that the spacing spacer 270 is made of a material having a low thermal conductivity such as a synthetic resin.

The AC component 130 is a means for transmitting heat or cool air conducted to the first conductive member 121 through the thermoelectric element 123 to the outer surface of the thermostat 110.

At this time, the AC flap 130 is interposed between the engaging step 117 and the engaging step 117 so as to surround the outer surface of the thermostatic chamber 110. Both ends of the AC flap 130 are connected to the first conductive piece 121, And the heat and cool air generated through the thermoelectric element 123 are conducted to the first conductive piece 121.

The thermoelectric element 123 is also referred to as a Peltier element.

At this time, the thermoelectric element is a device widely used in various industrial fields requiring temperature control to freely cool and heat a specific object by applying a current and to control the temperature.

That is, when a direct current is applied to the thermoelectric element, a temperature difference is generated on both surfaces thereof. At this time, the thermoelectric element undergoes endothermic (cooling) at a low temperature part and heat generation at a high temperature part. Further, the thermoelectric element can easily change the positions of the low temperature portion and the high temperature portion by changing the polarity of the applied current.

The heat insulating piece 140 is a means for preventing external leakage of heat or cool air transferred to the AC 130.

At this time, the heat insulating piece 140 is formed in a pair of two pairs so as to surround the AC piece 130, and is tightly fixed to the outer surface of the AC piece 130.

The controller 150 compares the detected temperature with the preset temperature through the temperature sensor 113 and controls the operation of the thermoelectric element 123.

That is, when the temperature detected through the temperature sensor 113 becomes lower than the set temperature, the controller 150 controls the operation of the thermoelectric element 123 so that the side contacting the first conductive piece 121 is heated And when the temperature detected through the temperature sensor 113 becomes equal to or higher than the set temperature, the side contacting the first conductive piece 121 is allowed to absorb heat (cooling).

Meanwhile, the insulated enclosure 260 is installed outside the thermostatic chamber 110 and serves as a means for interrupting thermal interception of the thermostatic chamber 110.

At this time, the insulated enclosure 260 is installed on the outer surface of the thermostatic chamber 110 with a set of two pairs of installation frames 261 to fix the thermostatic enclosure through bolts. A finishing piece 265 for finishing the space between the installation frame 261 and the thermostatic chamber 110 is installed at the upper end of the installation frame 261. Here, the finishing piece 265 is provided with an opening hole 263 for exposing the lid 111 provided at the upper end of the thermostatic chamber 110 to the outside.

Meanwhile, the blowing device 290 serves to quickly release heat and cool air, which is opposite to the heat and cold air, which is transmitted to the thermostatic chamber 110, among the heat and cold air generated through the thermoelectric element 123 .

That is, when electric current is supplied to the thermoelectric element 123 and heat is conducted to the first conductive piece 121, the cold conductive material is conducted to the second conductive piece 124 side. The cool air conducted to the second conductive piece 124 and the heat dissipating piece 126 is quickly discharged to the outside through the high-pressure air supplied through the air blower 290. Also, when current is supplied to the thermoelectric element 123 and cool air is conducted to the first conductive piece 121, heat is conducted to the second conductive piece 124 side. The heat conducted to the second conductive piece 124 and the heat dissipating piece 126 is quickly discharged to the outside through the high pressure air supplied through the air blowing device 290.

In the meantime, the present invention having the above-mentioned combination structure can improve the thermal efficiency and to cope with the temperature change of the thermostat by improving the structure of the temperature regulating unit that provides hot and cold air to the thermostatic chamber. Will be described in detail with reference to FIG.

FIG. 7 is a schematic view illustrating a temperature control unit in accordance with a preferred embodiment of the present invention. 9 is a cross-sectional view taken along the line AA in FIG. 5, and FIG. 10 is a cross-sectional view taken along line AA in FIG. 5, and FIG. 10 is a cross- 5 is a sectional view taken along line BB of Fig.

6 to 10, when the temperature of the interior of the thermostat 110 is detected to be lower than the preset temperature through the temperature sensor 113, the controller 150 supplies current to the thermoelectric element 123, So that the surface of the thermoelectric element 123, which is in contact with the first conductive piece 121, has a heating action.

The heat generated through the thermoelectric element 123 is transferred to the thermostatic chamber 110 through the first conductive piece 121 and the AC flute 130 and is supplied to the internal temperature So that the temperature becomes equal to the set temperature.

At this time, the heat insulating piece 140 blocks external exposure of the AC component 130 so that the heat transferred to the AC component 130 can be transmitted only to the thermostatic chamber 110 side.

If the temperature of the interior of the thermostat 110 is detected to be higher than the preset temperature through the temperature sensor 113, the controller 150 supplies current to the thermoelectric element 123, (Cooling) action of the surface contacting the first conductive piece 121.

The cool air generated through the thermoelectric element 123 is transferred to the thermostatic chamber 110 through the first conductive piece 121 and the AC flap 130 to be supplied to the internal temperature 115 of the accommodation space 115 formed in the thermostatic chamber 110 To a temperature equal to the set temperature.

The first conduction pieces 121 and the AC pieces 130 serving as mediators for transferring the heat and the cool air generated through the thermoelectric elements 123 to the thermostat 110 side are connected to the thermostat 110 So that the heat and cool air of the temperature control unit can be smoothly transmitted to the side of the thermostatic chamber. Thus, it is possible to closely cope with the temperature change of the thermostatic chamber and to improve the thermal efficiency.

Meanwhile, when heat is supplied to the thermostat 110 through the first conductive piece 121 and the AC piece 130, cold air is transmitted to the second conductive piece 124 and the heat dissipating piece 126.

The high-pressure air supplied through the air blowing device 290 passes through the air injection pipe I, the insertion space 129, and the air discharge pipe (not shown) O) of the present invention in the course of rapid movement along the longitudinal direction of the apparatus.

Accordingly, the present invention rapidly releases heat and cool air opposite to the heat and cool air transmitted to the side of the constant temperature bath to prevent heat exchange therebetween, thereby improving the thermal efficiency of the heat and temperature maintaining apparatus.
