Embodiment Construction

[0027] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment, see Figure 1-4 :

[0028] Enhanced heat transfer fins, including a flat substrate 1, formed on the flat substrate with corrugated fins 2 that protrude from the straight substrate 1 and form a certain angle with the flat substrate 1, and several corrugated fins 2 is provided with a reversing area 3, and the reversing area 3 divides the corrugated fins into several groups of corrugated fin areas A1, A2, A3 with different numbers of corrugations, and the wavelength L and amplitude H of each corrugated fin in each group The number of corrugated fins 2 in different groups and the wavelength L are not equal. The number of corrugated fins in the areas A1, A2, and A3 of each group of corrugated fins decreases in turn within the entire fin length X, and the wavelength L in turn Increase.

[0029] The unequal number of corrugated fins in the areas A1, A2 an...

Abstract

The invention belongs to the technical field of heat exchangers, which relates to an enhanced heat transfer fin and a production process thereof. The enhanced heat transfer fin comprises a flat and straight substrate, wherein waveform fins which are raised on the flat and straight substrate and form certain angle with the flat and straight substrate are formed on the flat and straight substrate, reversing areas are arranged between a plurality of the waveform fins and divide the waveform fins into a plurality of groups waveform fin areas with different numbers of ripples, the wavelength and the wave amplitude of each waveform fin in each group are equal to each other, the number and the wavelength of the waveform fins of different groups are no equal to each other, and the number of the waveform fins in each group of the waveform fin area decreases in turn in the whole fin length while the wavelength increases in turn. The production process of the enhanced heat transfer fin is to put an aluminum strip on a roll forming machine to form the enhanced heat transfer fin provided with the waveform fins and the flat and straight substrate through one-step rolling. The enhanced heat transfer fin has good heat transfer property and small resistance, and is suitable to serve as a heat transfer fin of an automotive heat exchanger, a water tank radiator, a pressurizing intercooler and a wind cooling type hydraulic oil cooler.

Description

technical field [0001] The invention belongs to the technical field of heat exchangers, and relates to an enhanced heat transfer fin and a production process thereof. Background technique [0002] Due to its light weight, small size and high heat transfer efficiency, compact heat exchangers have been widely used in the fields of automobiles, chemicals, refrigeration and air conditioning. The form of compact heat exchanger usually has tube-fin type, plate-fin type and tube-belt type. The aluminum heat exchanger composed of aluminum flat tubes and corrugated fins has a good heat transfer effect and has been widely used in the automotive industry. It has become a substitute for tube fins [1] [Document 1: Kim M H, Bullard C W, Air-side thermal hydraulic performance of multi-louvered fin aluminum heat exchangers, International Journal of Refrigeration, 2002, 25(3): 390-400]. For gas-liquid heat exchangers, the control thermal resistance of the entire heat exchanger is on the ai...
