Description

Technical Field

[0001] The utility model relates to the field of molecular biological instruments, in particular to a small-sized high-temperature metal bath. Background Art

[0002] The dry high temperature metal bath, also known as the digestion instrument, is controlled by a microcomputer and uses high-purity aluminum material as a heat-conducting medium to replace the traditional water bath device. It is a commonly used instrument for protein hydrolysis in molecular biology research. The digestion instrument is widely used in fields such as sample preservation and reaction, DNA amplification and pre-denaturation of electrophoresis, and serum coagulation.

[0003] Currently, the temperature control range of high-temperature metal baths on the market is mostly within 100°C. There are not many instruments with a maximum temperature control of more than 150°C, and they are large in size. Protein hydrolysis requires a higher temperature. In addition, due to the influence of metal radiation heat dissipation and rapid heat transfer, the bath cannot heat up quickly. At the same time, radiation heat dissipation will cause the environment outside the temperature control area to heat up, affecting the stable operation of electrical components in the electrical control area.

[0020] The utility model is described in detail below in conjunction with the accompanying drawings.

[0021] See also Figure 1-2 This embodiment provides a high-temperature metal bath with a compact volume, which includes a housing 1 with an electric control area and a temperature control area, a base plate 2 fixedly installed at the bottom of the housing 1, a metal module located in the electric control area, and a heat preservation component.

[0022] The housing 1 is hinged with a shell cover, and when the shell cover is opened, the metal module is exposed. The metal module includes a bath 3, a mounting plate 4, and a heating element 5 fixed to the bottom of the bath 3 through the mounting plate 4. The bath 3 is provided with a plurality of reaction liquid containing cavities, which are arranged in a matrix. The heating element 5 is a resistance wire or a heating tube. In this embodiment, the reaction liquid is heated in the bath 3 to promote the reaction process such as protein hydrolysis.

[0023] The bottom plate 2 is provided with an air inlet connected to the electric control area. The temperature control area is located at a position on the side corresponding to the electric control area, and the electric control area and the temperature control area are separated by a partition, and the partition is provided with air holes. In this embodiment, when the metal module is working, the temperature of the temperature control area rises, and the air is heated and moves upward to enter the area formed by the metal module when the shell cover is closed. At this time, a small air flow movement is formed, and the low-temperature air enters the electric control area along the air inlet, and then enters the temperature control area along the air holes, and finally enters the area formed by the metal module when the shell cover is closed. In the above process, the low-temperature air has a cooling effect on the electric control area. Therefore, the temperature of the electrical components in the electric control area will not rise excessively, thereby ensuring stable control performance.

[0024] The insulation assembly includes four groups of fixing plates I6 arranged around the metal module, foam insulation pads I7 filled between the metal module and the corresponding fixing plates I6, a fixing plate II8 located below the metal module, a foam insulation pad II9 filled between the fixing plate II8 and the metal module, and an insulation plate 10 located below the fixing plate II8. The fixing plate I6 is fixed to the bath 3 by screws, and the fixing plate II8 is fixed to the mounting plate 4 by screws, and fixing columns 11 are connected between the insulation plate 10 and the four corners of the fixing plate II8.

[0025] In this embodiment, the heat preservation component is used as the outer lining of the metal module to prevent the metal module from radiating heat, thereby avoiding the situation where the environment outside the temperature control area is heated up due to radiating heat, which affects the stable operation of the electrical components in the electric control area. In addition, since radiating heat is prevented, the heat loss is small, so that the bath 3 is heated up quickly. At the same time, the foam insulation pad II9 and the four foam insulation pads I7 are covered on the metal module in an encircling manner, and the insulation board 10 is combined to make the overall heat preservation component staggered, which effectively overcomes the problem of fast heat transfer between metals.

[0026] In summary, the high-temperature metal bath of this embodiment has the following advantages: the spatial layout is clever, and the excellent thermal insulation design makes the instrument compact, the temperature control range is large, and the temperature control is precise. It can prevent the metal module from radiating heat, avoid the environment outside the temperature control area from heating up due to radiating heat, and affect the stable operation of the electrical components in the electric control area. At the same time, it can achieve rapid heating and meet the application requirements of higher temperatures.

[0027] The naming of each component involved is based on the functions described in the specification, and is not limited to the specific nouns used in the utility model. Those skilled in the art may also choose other nouns to describe the names of the components of the utility model.
