Abstract

The utility model relates to a copper tube heat exchange evaporator for an evaporative type condenser. A plurality of copper tubes and transverse tubes at two ends of the copper tubes are communicated vertically to form an evaporator main body; each copper tube is provided with hydrophilic aluminum foil fins with uniform ripples; the hydrophilic aluminum foil fins are provided with a plurality of small even holes; the copper tubes are connected with the insides of small ports of hydrophilic aluminum foils; and the hydrophilic aluminum foils are provided with even heat exchange reinforcing ripples and hydrophilic coatings. The ripples of the fins of the copper tube heat exchange evaporator increase the heat exchange area outside the tubes, and the unique hydrophilic coatings reduce the corrosion phenomenon to utmost extent. The fins outside circular tubes improve the working bearing capacity of the copper tubes, and effectively increase the heat exchange area among the outsides of the tube bodies and air, thereby improving the heat exchange efficiency.

Description

Evaporative condenser copper pipe heat exchange evaporimeter

Technical field:

The utility model relates to a kind of evaporative condenser copper pipe heat exchange evaporimeter.

Background technology:

Existing evaporative condenser, heat exchange pipe adopts is the steel light pipe, adopts circle or ellipse light pipe mostly, and its heat transfer outside a tube area is less, and the coefficient of heat conduction is little, and its thermal efficiency is lower.

Summary of the invention:

The purpose of this utility model provides a kind of copper pipe string hydrophilic aluminium foil finned tube that improves the evaporative condenser heat exchange efficiency.The purpose of this utility model realizes by following structure: a kind of evaporative condenser copper pipe heat exchange evaporimeter, many row's copper pipes constitute vaporizer body with upper and lower connection of two ends transverse tube, the hydrophilic aluminium foil fin that has even ripple on every copper pipe, a plurality of uniform small pores are arranged on the hydrophilic aluminium foil fin, copper pipe is connected in the osculum of hydrophilic aluminium foil, have the ripple of even reinforcement heat exchange on the hydrophilic aluminium foil fin, have hydrophilic coating on the aluminium foil.The utility model is a kind of evaporative condenser with copper pipe heat exchange evaporimeter, and the ripple that fin and fin have increases the heat transfer outside a tube area, the minimizing that its distinctive hydrophilic coating is also maximum corrosion phenomenon.The fin that pipe is outer has improved the work bearing capacity of copper pipe.Effectively increased the heat exchange area of body outside, thereby improved heat exchanger effectiveness with air.Finned tube is formed by machinery and mold high speed string system in process of production, and spacing is well-balanced.The utility model provides the evaporating type condensing heat exchanger that a kind of production cost is minimum, heat exchange efficiency is the highest for evaporative condenser, hydrophilic coating on the fin can prevent corrosion effectively, and the increase heat exchange area, greatly improved the heat exchange property of evaporative condenser.

The specific embodiment:

The utility model as shown in Figure 1 is a kind of evaporative condenser copper pipe heat exchange evaporimeter, on many row's copper pipes 1 and the two ends transverse tube, as shown in Figure 3, following connection constitutes vaporizer body, the hydrophilic aluminium foil fin 2 that has even ripple on every copper pipe 1, a plurality of uniform small pores are arranged on the hydrophilic aluminium foil fin 2, and copper pipe is connected in the osculum of hydrophilic aluminium foil, as shown in Figure 2, have the ripple of even reinforcement heat exchange on the hydrophilic aluminium foil fin 2, have hydrophilic coating 3 on the aluminium foil.

The ripple that has even reinforcement heat exchange as shown in Figure 2, has hydrophilic coating 3 on the aluminium foil.

Hydrophilic coating on the utility model fin can prevent corrosion effectively, and the outer numerous fin of pipe has increased heat exchange area, has greatly improved the heat exchange property of evaporative condenser.Reduced the volume of evaporative condenser.
