Description
Technical Field
The utility model belongs to the technical field of electric heat exchangers, and particularly relates to a heating element of a corrugated pipe cast aluminum heat exchanger.
Background
A heat exchanger (heat exchanger) is a device that transfers a portion of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. The heat exchanger plays an important role in chemical industry, household appliances, petroleum, power, food and other many civil and industrial productions, and can be used as a steam generator, a water heater, a heating stove, a water dispenser, a physiotherapy instrument, an incubator, a water evaporation furnace, a steam cleaning (ironing) machine and the like (taking heat conducting materials such as air, alcohol, water, oil and the like as mediums) in the chemical production, and has wide application.
The heating element in the existing heat exchanger is produced by adopting light straight pipes with thicker walls, so that the surface temperature and the heat exchange efficiency of the heating element are limited in a limited space, and the heating element cannot meet the increasing energy-saving and environment-friendly high requirements of people.
Disclosure of Invention
The utility model aims to provide a heating element of a corrugated pipe cast aluminum heat exchanger, which is used for solving the problems in the prior art.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
the corrugated pipe cast aluminum heat exchanger heating body comprises a heat exchanger heating body, wherein the heat exchanger heating body is an electric heating element made of cast aluminum, the heat exchanger heating body is of a corrugated pipe structure, and the wall thickness of a corrugated pipe of the heat exchanger heating body is 0.18-0.59mm.
The beneficial effects are that: the heating element of the cast aluminum heat exchanger adopts the hand-torn steel and the ultra-thin wall-thickness corrugated pipe, so that the heat exchange area is greatly increased, the heat exchange efficiency is improved by more than about one and four times, the surface temperature of the heating element is reduced, the surface temperature is lower than the outlet temperature, the energy is saved, and the cost is greatly reduced. Specifically, this heat exchanger heat-generating body is cast aluminium and makes, electric heating element bellows casts into integrative structure, and the bellows wall thickness of heat exchanger heat-generating body is 0.18-0.59mm (the pipe wall thickness of current straight tubular heat exchanger heat-generating body is 0.6-1.2 mm), under the same circumstances of internal diameter and the internal diameter of current heat exchanger heat-generating body of this heat exchanger heat-generating body, the heat exchanger heat-generating body changes into the bellows structure from straight tubular structure, make the girth of this heat exchanger heat-generating body increase by a wide margin for the girth of current heat exchanger heat-generating body, length surface area also increases by a wide margin, and then make the heat transfer area of this heat exchanger heat-generating body greatly increased, the coefficient of heat conductivity and the wall thickness of combination material, according to actual calculation, improved heat exchange efficiency roughly more than a bit, moreover, current straight tubular inner wall smooth heat transfer medium passes through fast, the heat absorption is few, and the bellows structure of this patent application can produce the vortex collision in the ripple position when medium flows, collision can increase heat transfer efficiency equally, simultaneously, the pipeline of this heat exchanger body is thinner, the wall thickness is then heat transfer efficiency increases by a wide margin, the heat transfer efficiency is improved more, and the heat transfer efficiency is improved more than a wide margin, and the heat transfer efficiency is reduced, the surface has reduced the environmental protection and has reduced the cost.

Detailed Description
In order to more clearly illustrate the embodiments of the present utility model or the technical solutions in the prior art, the present utility model will be briefly described below with reference to the accompanying drawings and the description of the embodiments or the prior art, and it is obvious that the following description of the structure of the drawings is only some embodiments of the present utility model, and other drawings can be obtained according to these drawings without inventive effort to a person skilled in the art. It should be noted that the description of these examples is for aiding in understanding the present utility model, but is not intended to limit the present utility model.
Examples:
as shown in fig. 1 and 2, this embodiment provides a corrugated tube cast aluminum heat exchanger heat-generating body, including heat exchanger heat-generating body 1 (see fig. 1 as the cross-sectional view of the heat exchanger), heat exchanger heat-generating body 1 is the electric heating element that cast aluminum made, and heat exchanger heat-generating body 1 is the bellows structure, the bellows wall thickness of heat exchanger heat-generating body 1 is 0.18-0.59mm (the wall thickness of current straight tubular heat exchanger heat-generating body is 0.6-1.2 mm), under the same condition of the internal diameter of this heat exchanger heat-generating body 1 and the internal diameter of current heat exchanger heat-generating body, the heat exchanger heat-generating body changes from the straight tube structure into the bellows structure, make the girth, length of this heat exchanger heat-generating body 1, for the girth greatly increased of current heat exchanger heat-generating body, and then make the heat transfer area greatly increased of this heat exchanger heat-generating body 1, and the coefficient of heat conductivity and the wall thickness of combination material, according to actual calculation, improved heat exchange efficiency roughly more four times, current inner wall smooth heat exchange medium passes through, and is few, and when medium flows, can produce the medium flow, the same heat exchange efficiency is more at the same place, the heat exchanger heat-generating heat-absorbing efficiency is more, and the heat-absorbing efficiency is reduced, and the heat efficiency is further reduced, the heat exchanger heat is more and the heat-absorbing efficiency is more and the heat.
In conclusion, the thin-wall corrugated pipe is adopted as the heating element of the heat exchanger, so that the heat exchange area is greatly increased, the heat exchange efficiency is improved by about four times, the surface temperature of the heating element is reduced, the energy is saved, and the use cost is reduced.
