Abstract

A micro heating device according to an embodiment of the inventive concept comprises a support part having at least one or more heating part, an oil chamber positioned over the support part and filled with oil therein, a specimen chamber having a reaction space into which a specimen is loaded and which is provided so as to be dipped into the oil, and a drive part configured to move the specimen chamber in the oil. The specimen chamber includes a temperature sensor for measuring a temperature of the specimen chamber.

First claim

What is claimed is:

1 . A micro heating device comprising:
a support part having at least one or more heating parts; an oil chamber positioned over the support part and receiving oil therein; a specimen chamber having a reaction space into which a specimen is loaded and which is provided so as to be dipped into the oil; and a drive part configured to move the specimen chamber in the oil, wherein the specimen chamber comprises a temperature sensor for measuring a temperature of the specimen chamber.

2 . The micro heating device of claim 1 , further comprising a control unit configured to control the specimen chamber and the drive part,
wherein the control unit controls the drive part to move the specimen chamber along the oil chamber and to stop the specimen chamber when a temperature measured by the temperature sensor reaches a preset temperature.

3 . The micro heating device of claim 2 , wherein the control unit controls the drive unit again to move the specimen chamber along the oil chamber when a set time elapses after stopping the specimen chamber.

4 . The micro heating device of claim 3 , wherein the oil chamber is provided in a ring shape on the heating part.

5 . The micro heating device of claim 4 , wherein the at least one or more heating parts are provided in plurality, and the plurality of heating parts are disposed along the ring shape.

6 . The micro heating device of claim 5 , wherein the drive part comprises:
a holder part configured to support the specimen chamber; a motor configured to move the holder part; and a guide rail configured to guide the motor so as to be moved along the oil chamber.

7 . The micro heating device of claim 6 , wherein the oil chamber has a first radius, and the guide rail has a same center as the oil chamber and is provided in a ring shape having a second radius greater than the first radius.

8 . The micro heating device of claim 6 , wherein the guide rail is formed along an outer circumference of the oil chamber.

9 . The micro heating device of claim 8 , wherein the surface of the reaction space is hydrophobically treated.

10 . The micro heating device of claim 9 , wherein the temperature sensor may comprise at least any one of metal, metal compound thermocouple, or metal oxide.

11 . The micro heating device of claim 10 , wherein the reaction space is formed on a substrate, and the specimen chamber further comprises a cover configured to cover an upper portion of the reaction space.

12 . The micro heating device of claim 2 , wherein the control unit controls the drive unit again to move the specimen chamber again along the oil chamber when the measured temperature deviates from the set temperature after stopping the specimen chamber.
