Abstract

A highly-effective gill tube heat exchanger is mainly used for the heat exchange of liquid and gas. The structure is that a tube is provided with teeth inside, and is provided with gills outside, and the gills and the surface of the tube are provided with ribs, thereby not only increasing the heat exchange area on the inside and outside of the pipe, but also strengthening the mechanical intensity of the gill tube. The proportion of the inner area and the surface area of the tube can be determined according to the heat exchange coefficient rate of liquid and gas. The heat exchanger not only increases the heat exchange efficiency inside and outside the tube, but also reduces material consumption, thereby reducing liquid usage in the tube, and realizing the energy-saving purpose.

Description

High-efficiency fin tube

Technical field

The present invention relates to the heat exchanger in the heat-exchange system, be specifically related to a kind of fin tube that can improve heat exchanger effectiveness, belong to international monopoly class F28F3/00 " parts of interchangeable heat exchange or heat-transfer equipment " technical field.

Background technology

Adopt copper or the circular light pipe of steel mostly for the heat transfer of liquid refrigerant and air in the prior art.When adopting circular light pipe, the coefficient of heat transfer of manage outside air owing to the liquid refrigerant coefficient of heat transfer in the pipe greatly is less, and it is unreasonable to manage inside and outside heat exchange area ratio, and heat exchange efficiency is very low, causes the system energy consumption increase, waste of raw materials.

Summary of the invention

It is that pipe and a plurality of fin are the fin tube of one that the present invention is designed to section, can overcome above-mentioned shortcoming, provides a kind of and can make the inside and outside both sides of pipe heat exchange area coupling rationally, and interior outside heat exchange efficiency is improved.It can reduce material consumption, reduces the use amount of tube refrigerant, energy-saving heat exchanger.

Description of drawings

The high-efficiency fin heat exchange of heat pipe comprises the rib composition of managing internal tooth, pipe and fin, reaching pipe and fin outside.Fig. 1 is the sectional drawing of high-efficiency fin heat exchange of heat pipe monolithic fin tube.By surface fin 1 with ribbing, the pipe 2 that the surface is with ribbing is with internal tooth pipe 3 to form among the figure.Fig. 2 is two pipe sectional drawings, and Fig. 3 is the sectional drawing of three pipes, and Fig. 4 is the sectional drawing of eight pipes.Fig. 5 is a utility model fin tube heat exchanger structure close-up view, and fin tube 4 among the figure, leading screw 5, bend pipe 6.Form the cold smoke channel effect in this structural tube between low-temperature receiver and the fin tube, improved heat convection efficient.

The specific embodiment

Become the fin tube extrusion die by above-mentioned Section Design, adopt the metal fever extrusion process, extrusion modling with the single fin tube punching of moulding, passes sheet, and leading screw is fastening, and bend pipe connects, and seal welding is formed the large tracts of land calandria heat exchanger, is used for the evaporimeter of freezer.Fin outside pipe can be made into 18 of a slices to eight.Be made into a slice (as Fig. 1), be made into two (as Fig. 2), be made into three (as Fig. 3) and be made into eight (as Fig. 4)

Claims

1. high-efficiency fin tube, its structure is in the pipe tooth to be arranged, and fin is arranged outward, fin and tube-surface are provided with rib.

2. high-efficiency fin tube according to claim 1, the fin quantity outside pipe can be made into 18 of a slices to eight.

3. high-efficiency fin tube according to claim 1, the angle between the fin outside the pipe can be adjusted arbitrarily according to using needs.

4. high-efficiency fin tube according to claim 1, the quantity of pipe internal tooth is adjusted from 0-∞, and its shape can be according to using needs to adjust arbitrarily.The quantity of tube outer surface and flap surface rib is adjusted its shape from 0-∞ can be according to using needs to adjust arbitrarily.

5. high-efficiency fin tube according to claim 1 is characterized in that the high-efficiency fin tube proper alignment of multi-disc is fixed with the leading screw cross-under, with bend pipe single fin tube is connected then, constitutes multi-disc liquid, gas heat exchanger.
