Air temperature vaporizer free from frosting and freezing

Abstract

The invention relates to an air temperature vaporizer free from frosting and freezing. The air temperature vaporizer free from frosting and freezing comprises a heat exchange pipe, wherein a pluralityof heat exchange fins which are annularly and axially arranged at intervals are arranged on the surface of the circumferential side of each heat exchange pipe; a heat exchange channel is formed between each two adjacent heat exchange fins; an electric heating assembly is arranged in each heat exchange channel; and each electric heating assembly is at least connected and fixed to the surface of one heat exchange fin or the surface of the heat exchange pipe. During use in a low-temperature environment, heat is generated by the electric heating assemblies and transferred to the heat exchange pipe and the heat exchange fins, temperatures of 0 DEG C and above, of the outer surface of the heat exchange pipe and the outer surfaces of the heat exchange fins are kept, and no frosting and no freezing are achieved; the air temperature vaporizer free from frosting and freezing is capable of making direct contact with air and carrying out heat exchange, unlimited by weather and use site, and stable and reliable in use performance; the environment temperature is furthest utilized, and meanwhile, the heat of the heat exchange pipe is capable of heating a low-temperature medium in the pipe, and air energy and electric energy are organically combined, so that the purposes of energy conservation and environment protection are achieved; and a gas temperature of an output end can further be controlled in real time, and the safety of connection equipment at the output end is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of air-temperature evaporators, and in particular relates to an air-temperature evaporator without frosting and icing. Background technique [0002] At present, the air-temperature evaporator does not require electricity or fuel, and can heat the low-temperature medium (cryogenic liquid) from minus 196°C to normal temperature gas only by relying on the heat sink of the evaporator to absorb air heat. Therefore, it is widely used in the petrochemical field, especially the natural gas industry. . [0003] However, the applicant found that in the existing air-temperature evaporators on the market, in winter, because the temperature in the north is below zero, all the outer surfaces of the heat exchange fins of the air-temperature evaporator are frosted and frozen, so that the heat exchange fins It cannot be in contact with the air, which greatly reduces the heat exchange efficiency between the heat exchange fin...

Problems solved by technology

This necessitates the provision of an additional heating system

[0005] In addition, the existing air-heated carburetor is also limited in displacement design due to the limited use of space, which also affects the application of the air-heated carburetor to a certain extent. It cannot be controlled in real time, and the temperature of the output gas cannot be guaranteed to meet the requirements of the equipment, and there are certain potential safety hazards
