Heat conduction block

Abstract

The invention discloses a heat conduction block, and is characterized in that: the heat conduction block consists of two parts, the first part is heat conduction columns, the heat conduction columns each have a columnar structure made of a high heat conductivity material, an end face of a column body of each heat conductivity column is a plane connected with a plane of a heat source, the other end of the column body of each heat conductivity column is provided with a conical hole or a cylindrical hole, and the surface of the conical hole or the cylindrical hole is matched with the outer surface of a reaction tube; and the second part is a frame structure made of a low heat conductivity material, the frame structure is provided with one or more through holes, and the heat conductivity columns can be placed in the through holes of the frame structure. The heat conduction block reduces the potential safety hazard, reduces the heat capacity, reduces the energy loss, and decreases the manufacturing cost.

Description

technical field [0001] The invention relates to heat conduction technology, in particular to a composite material heat conduction block. Background technique [0002] Almost all biochemical reactions in the laboratory need to be carried out at a specific temperature. In order to maintain the specific temperature required for the reaction, the reaction solution is usually placed in a reaction test tube. In order to maintain the temperature required for the reaction, the test tube needs to be placed in a thermostatically controlled device with heating or cooling capabilities. Common such constant temperature control devices include constant temperature ovens, constant temperature water baths, dry metal baths, etc. Because the operation with dry metal bath is relatively clean, it is not easy to pollute the test tube, and it occupies a small area. Dry metal bath will gradually replace other constant temperature equipment. Because the reaction test tube is generally cylindrical...

Problems solved by technology

The disadvantages of using a metal block as a heat conduction block are:

[0004] 1. It is easy for the user to touch the surface of the metal block when placing the test tube into or removing it from the metal block. When the temperature of the metal block is high or low, it may cause discomfort to the user, and may even be harmful to the user. Deals burn or frostbite damage

[0005] 2. The surface of the metal block will lose heat energy to the surrounding environment

[0007] 4. The production cost is high, this is because the cost of the metal itself is high, and the production cost of multiple processing procedures is also high

[0008] 5. The metal block is very heavy. If copper or silver is used as the material, the weight will be even greater
