Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal bath insulation technology, and more specifically, to a multi-layered metal bath composite insulation structure. Background Technology
[0002] Metal baths are devices that use metal as the heat transfer medium to achieve constant temperature treatment of samples or workpieces through precise temperature control. They are widely used in laboratory analysis, industrial manufacturing, medical testing, and other fields. Their core function relies on stable temperature field control, and thermal insulation performance is a key factor affecting temperature control accuracy, energy efficiency, and operational safety. Inefficient thermal insulation leads to rapid heat loss, increasing the energy consumption of the heating module, causing excessively high temperatures on the equipment casing, and disrupting the stability of the internal temperature field.
[0003] Existing publication number CN118179629A discloses a metal bath temperature control device. This device includes several individually heated and temperature-controlled metal bath modules, with slots formed between adjacent modules for inserting blocks; these blocks are heat insulation plates and / or metal blocks. Through its modular design, the metal bath temperature control device allows for simultaneous testing of multiple items at different temperatures by inserting heat insulation plates and / or metal blocks between adjacent heating modules. It also allows for the use of some or all of the heating modules based on sample data. The heating modules have channels through which cooling air or oil can be continuously passed, carrying away heat and achieving rapid cooling. The inventors discovered the following problems with the existing technology during the development of this invention:
[0004] Existing metal bath insulation structures are relatively simple. Traditional materials such as glass wool and polyurethane can only suppress heat conduction or convection, but cannot block heat radiation at the same time. In particular, their insulation effect is not ideal under high temperature radiation, resulting in low overall insulation efficiency.
[0005] Therefore, a multi-layered thermal insulation metal bath composite thermal insulation structure is proposed to address the above problems. Utility Model Content

[0014] Preferably, a plurality of anti-slip pads are fixedly attached to the bottom of the metal bath body; the anti-slip pads are made of rubber.
[0015] The technical effects and advantages of this utility model are as follows:
[0016] 1. Compared with the prior art, this multi-layer heat-insulating metal bath composite heat insulation structure is provided with honeycomb unit holes, heat insulation board, and bearing block. The inner layer uses heat insulation core material with low thermal conductivity to suppress heat conduction, and honeycomb unit holes are reserved between layers to weaken air convection heat transfer.

Subsequently, the first magnetic block and the second magnetic block magnetically attract each other to realize the convenient fixing and unlocking of the sealing cover. This can form multiple seals for the sealing cover, enhance the temperature control accuracy of the equipment, effectively prevent dust and moisture from entering, and protect the internal components.

[0033] In a preferred embodiment, a slider 6 is fixedly connected to the side wall of the sealing cover 51; when the sealing cover 51 contacts the top of the metal bath body 1, the slider 6 slides into the middle of the positioning plate 61; the positioning plate 61 is fixedly connected to the top of the metal bath body 1; a groove 62 is provided on the top of the positioning plate 61; the groove 62 is adapted to the size of the slider 6; the slider 6 slides in the middle of the groove 62, at which time the sealing cover 51 is pushed down and pressed tightly, and then the slider 6 contacts the top of the metal bath body 1 to form an annular sealing surface, blocking the air flow between the orifice and the outside.

They can be customized or selected according to actual needs. Here we are just using them without making any structural or functional improvements, so we will not go into detail here.
[0037] The working process of this utility model is as follows: First, place test tubes, centrifuge tubes and other containers in the middle of the metal bath hole 16. At this time, the heat insulation cotton 4 can adhere to the surface of the container to reduce the heat loss from the middle of the metal bath hole 16. After the container is installed, the end of the sealing cap 51 can be moved to the top of the metal bath body 1. At this time, the slider 6 slides into the middle of the positioning plate 61. Then push the sealing cap 51 downward to press it tightly. Subsequently, the slider 6 contacts the top of the metal bath body 1. The first magnetic block 7 and the second magnetic block 71 attract each other to form an annular sealing surface, blocking the air flow between the hole and the outside. Sliding the slider 6 in the opposite direction can release the pressure and open the sealing cap 51. The container is located in the middle of the cavity 52. The sealing cap 51 can form a seal on the top of the metal bath body 1, blocking the air flow between the hole and the outside and reducing the heat loss due to convection.
[0038] Heating elements are installed at the bottom of the support block 15, converting electrical energy into heat energy to heat the module. The support block 15, in close contact, evenly transfers heat to the test tube. Simultaneously, numerous hexagonal pores within the honeycomb unit holes 2 form independent, closed air chambers. Air is divided into small units, making convection difficult and significantly reducing convective heat transfer. This, combined with the heat insulation plate 21, further blocks heat conduction. The metal bath body 1 incorporates a high-precision temperature sensor that monitors the module temperature in real time and feeds the data back to the display screen 12. The temperature can be adjusted via button 11. When the actual temperature is lower than the set temperature... When the value is increased, the heating power is increased to maintain the sample in the test tube within a stable temperature difference range. When heating different containers, the heat insulation component 14 can be directly removed from the middle of the limiting frame 13. During installation, the limiting block 3 is inserted into the middle of the positioning groove 31 to limit its position. At the same time, the high friction coefficient of the anti-slip pad 8 is used to increase the friction between the metal bath body 1 and the placement surface, preventing the metal bath body 1 from sliding or tipping over in the operation or vibration environment, thus ensuring experimental safety. The above is the working principle of this multi-layer heat-insulating metal bath composite heat insulation structure.
