Description
Technical Field
The invention relates to the technical field of novel refrigeration, in particular to an enhanced heat transfer structure and an enhanced heat transfer method applied to a infinitesimal regenerative system.
Background
In recent years, the international society has been strictly restricted in the emission of greenhouse gases. New refrigeration technologies are urgently needed. Room temperature magnetic refrigeration is considered as one of the technological routes to cope with the elimination of HFCs. The room temperature magnetic refrigeration technology is a novel refrigeration technology based on the giant Magnetocaloric Effect (MCE) of a Magnetocaloric material in a room temperature region. It has comparable advantages over vapour compression refrigeration technology: the solid magneto-thermal material is used as a refrigeration working medium, common fluid such as water is used as a heat transfer medium, and the solid magneto-thermal material is environment-friendly, quiet in operation and low in working pressure; the theoretical refrigeration efficiency based on the magnetocaloric effect can reach 60% of that of the Carnot cycle, has good energy-saving potential, and can indirectly reduce the emission of greenhouse gases. Therefore, the room temperature magnetic refrigeration technology has good application prospect.
The magnetic refrigeration technology needs to design reasonable and effective refrigeration circulation according to the magnetocaloric effect to realize the purpose of refrigeration, and a patent of parallel infinitesimal regenerative system for room-temperature magnetic refrigeration, which is published in the patent application number CN 202931688A, has invented a parallel infinitesimal regenerative system for room-temperature magnetic refrigeration, and elaborates the main components and the structure of the system in detail. The realization mode of the heat regeneration process of the system is as follows: and the high-temperature magnetocaloric material of the moving disc of the heat regenerator in the strong magnetic field releases heat to the low-temperature magnetocaloric material of the moving disc of the heat regenerator outside the magnetic field, and the low-temperature magnetocaloric material of the moving disc of the heat regenerator outside the magnetic field absorbs heat from the high-temperature magnetocaloric material of the moving disc of the heat regenerator in the strong magnetic field. In order to meet the requirements of heat transfer and mutual movement between the two regenerator moving disks, an interlayer heat conduction lubricating module is designed to be positioned between the two regenerators, and a heat conduction lubricating block is filled in the interlayer heat conduction lubricating module to ensure that the regenerator moving disk and the regenerator moving disk are fully attached and contacted. However, the heat recovery method has the problem of low heat conduction and heat transfer rate, and the magnetocaloric material is the core of the room-temperature magnetic refrigeration technology, and the thermal conductivity is generally low, which is the physical property of the material itself. The limitation of the thermal conductivity problem is an important property that affects the performance of pure solid state magnetic refrigeration. For the micro-element regenerative cycle, there are two main aspects that can further enhance heat transfer: the heat transfer in the magnetic thermal working medium is strengthened, and the heat transfer between the two heat regenerators is strengthened.

The middle heat transfer plate comprises an annular guide rail and a heat-conducting lubricating block. And an enhanced heat transfer structure is arranged between the adjacent rotary magnetic refrigeration heat regenerator modules and the middle heat transfer plate. The enhanced heat transfer structure transfers the high-temperature magnetic thermal working medium in the magnetic field to the low-temperature magnetic thermal working medium outside the magnetic field.
Taking the first rotary magnetic refrigeration heat regenerator module as an example, the first rotary magnetic refrigeration heat regenerator module comprises a fixed arc-shaped permanent magnet magnetic field, a heat regenerator moving disk rotating and penetrating through the permanent magnet magnetic field, and a magnetic thermal working medium uniformly embedded on the heat regenerator moving disk.

The width of the arc-shaped high magnetic field region gap is 10-40 mm. The magnetocaloric working medium is formed by mixing and pressing a pure magnetocaloric material 202 and a heat conduction material 201. The above-described structure is not shown in the drawings.
As shown in fig. 1, the enhanced heat transfer structure applied to the infinitesimal heat regenerator system includes a first magnetocaloric working medium 2 located in the first rotary magnetic refrigeration heat regenerator module, a second magnetocaloric working medium 4 located in the second rotary magnetic refrigeration heat regenerator module, and a heat-conducting lubricating block 3 located in the middle heat transfer plate.
