Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment, see Figure 1-4 :

[0023] To strengthen the heat transfer fins, corrugated fins 2 protruding from the flat substrate 1 and forming a certain angle with the flat substrate 1 are formed on the flat substrate of the corrugated plate. The reversing area 3, 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 are equal. The number of corrugated fins 2 and the wavelength L are not equal, the number of corrugated fins in each group of corrugated fin areas A1, A2, A3 decreases sequentially within the entire fin length X, and the wavelength L increases sequentially.

[0024] The unequal number of corrugated fins in the areas A1, A2 and A3 of each group of corrugated fins mentioned above means: t...

Abstract

The invention belongs to the technical field of heat exchangers, which relates to an enhanced heat transfer fin. Waveform fins are formed on a flat and straight substrate of a corrugated plate, the waveform fins are raised on the flat and straight substrate and form certain angle with 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 enhanced heat transfer fin of the invention 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. 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 air side. For this reason, various ...
