Problems solved by technology

[0007] It can be seen that the working fluid in each turn of the hollow spiral tube is increasing. Then, in order to meet the final actual cooling needs, more turns may be wound, which will inevitably lead to an increase in the volume of the entire heat exchanger. Large, thus hindering the mass production of equipment

[0124] Combination of mosquito coils and equal-amplitude spiral tubes

[0125] multiple as Figure 7a The "inlet" and "outlet" of the mosquito coil unit shown are connected end to end, and the composition is as follows: Figure 7b , 7c and the mosquito coil assembly shown in 7d, wherein Figure 7b is the front view, Figure 7c is a stereogram, Figure 7d for side view. Figure 7b Among them, 1-8 are the serial numbers of the mosquito coils. Mosquito coil components such as Figure 7e As shown, it is composed of a mosquito coil unit and fins. Each mosquito coil unit is fixed with the shaft by fins to form a whole structure, from Figure 7f and 7g It can be seen that the channel of the mosquito-repellent coil is connected and fixed with the rotating shaft through the fins, and the fin not only plays a role of fixing the mosquito-repellent coil unit and the rotating shaft, but also plays a role of increasing the heat transfer area. In order to further increase the effec...

[0158] will be like Figure 8 Shown, that is, the spiral tube structure in Fig. 4 of Chinese patent ZL03 2 47628.0, according to the method of the aforementioned composite spiral tube member heat exchanger, the Figure 8 The single-layer structure is transformed into a multi-layer spiral tube structure, that is, on the outside of the original single-layer dumbbell-shaped spiral tube assembly, one or more layers of dumbbell-shaped spiral tube components similar to the original structure can be superimposed, and equal-amplitude spiral tube components can also be superimposed. Tubes and other shapes of spiral tube components. In this way, some deficiencies of the prior art are fundamentally improved. After adopting the multi-layer spiral tube structure, the original advantages can be maintained, and the original shortcomings of not being easy to increase the effective heat exchange area can be overcome, so that the effective heat exchange area can be greatly increased.

[0162] will be like Figure 9 Shown, that is, the spiral tube structure in Fig. 5 in Chinese patent ZL03 2 47628.0, according to the method of the aforementioned composite spiral tube member heat exchanger, will be as follows Figure 9 The single-layer structure shown is transformed into a multi-layer spiral tube structure, that is, on the outside of the original single-layer spiral tube component, one or more layers of spiral tube components similar to the original structure are superimposed, and equal-width spiral tubes can also be superimposed. Spiral tube assemblies in other shapes. In this way, some deficiencies of the prior art are fundamentally improved. After adopting the multi-layer spiral tube structure, the original advantages can be maintained, and the effective heat exchange area can be greatly increased.

[0163] The specific method is: use two or more such as Figure 9 The similar-shaped spiral tubes or equal-width spiral tube structures shown are nested, and...

Abstract

The invention discloses a composite spiral tube heat exchanger, which comprises left and right horizontal two chambers that passed by heat conductors and the rotary axle through said chambers. Wherein, two chambers are mounted with hollow spiral tubes whose central axles are said rotary axles; said hollow spiral tubes via the throttle valve and the reflux tube are connected to a closed fluid circuit; when said circuit is filled with medium and driven by outer driver to rotate around the rotary axle, one spiral tube will emit heat, while another will adsorb heat; said hollow spiral tubes comprise at least two layers of hollow spiral tubes which they are directly through or through via dual-end fluid device. The invention can be used to produce the device with eccentric refrigerating theory.

Description

technical field [0001] The present invention relates to a heat exchange device utilizing phase transformation of working fluid in a closed pipeline to refrigerate and generate heat, in particular to a heat exchange equipment in which the condensation and evaporation of working fluid are realized by the rotation of a spiral tube. Background technique [0002] The heat exchange equipment that uses the phase change of the working fluid in the closed pipeline to refrigerate and generate heat in the prior art usually uses moving parts such as compressors to directly interact with the working medium to achieve the purpose of condensation and evaporation of the working medium due to pressure changes . This kind of heat exchange equipment has problems such as low efficiency, large mechanical loss, complex overall structure and difficult maintenance. [0003] Just because of the existence of the above problems, people have been looking for other possible technical approaches to repl...
