Abstract
The utility model relates to a heat transfer element with a pipe integrated with corrugated fins and belongs to the field of thermal machinery. The heat transfer element consists of corrugated radiating fins 1 and a rectangular heat-transfer flat pipe 2 which are integrated with each other, wherein two to three rectangular passages 3 with identical sections are arranged in the rectangular flat pipes. Heat transfer performance of the heat transfer element is improved greatly, the weight thereof is reduced, materials thereof are saved and production cost thereof is decreased, and further, the heat transfer element is compact in structure and small in size. Since the corrugated radiating fins are integrated with the heat-transfer flat pipe, welding operation is omitted, manufacturing process is simplified and pollution to environments is avoided. In addition, the heat transfer element is high in vibration resistance, the radiating fins cannot be separated from the flat heat transfer pipe due to sharp vibration, and accordingly the heat transfer element can be applied to various heat exchangers well.
Description
Technical field
The utility model relates to a kind of monoblock type corrugated fin pipe heat transfer element that is applied to all kinds of heat exchangers, belongs to thermodynamics mechanical device category.
Background technology
The heat transfer element that uses on the heat exchanger of existing air-conditioning, vehicle, refrigeration plant generally is made up of copper pipe (or aluminum pipe) and aluminium fin, the heat-transfer pipe of heat transfer element and radiating fin (claiming the secondary heat-transfer area again) are for split type, usually adopt the method for soldering to connect, manufacturing and processing technology are comparatively complicated.Because factors such as crudy tend to occur the soldering deficiency, cause its thermal contact resistance bigger; Its shock resistance is relatively poor on the structure, the work under bad environment of some heat exchanger (as engineering truck), behind the heat transfer element operation certain hour, junction at radiating fin and heat-transfer pipe is easy to generate fracture, thereby further strengthened the thermal contact resistance between heat-transfer pipe and the radiating fin, caused its heat transfer property significantly to descend.For fear of the defective of existing heat transfer element because of adopting not enough big thermal contact resistance, process for machining and manufacturing complexity and radiating fin that produces of soldering or soldering and heat-transfer pipe to be easy to generate fracture, the utility model has designed a kind of monoblock type corrugated fin pipe heat transfer element, this component structure compactness, volume is little, in light weight, the heat transfer efficiency height can significantly promote the heat transfer property of heat exchanger, save material, reduce production costs.
The utility model content
The utility model relates to a kind of monoblock type corrugated fin pipe heat transfer element, comprises heat transfer flat tube and radiating fin.Wherein, heat transfer flat tube and radiating fin are monolithic construction, one machine-shaping, and radiating fin is a bellows-shaped, is distributed in the upper and lower both sides of heat transfer flat tube, and radiating fin is vertical with the heat transfer flat tube, and the spacing between the radiating fin is S
f, radiating fin thickness is δ, highly is H
p, the wavelength of ripple radiating fin is L
4, wave height is H, heat transfer flat tube section thickness is W
1, width is L
1, evenly being furnished with 2～3 not connected rectangular channels in the heat transfer flat tube vertically, the rectangular channel section thickness is W
2, width is L

The utility model monoblock type corrugated fin pipe heat transfer element is compared than existing heat exchanger heat transfer element and is had the following advantages:
(1) heat transfer property is significantly improved.The radiating fin of this monoblock type corrugated fin pipe heat transfer element and heat transfer flat tube adopt monoblock type, eliminated thermal contact resistance, radiating fin is a bellows-shaped simultaneously, flow-disturbing when fluid skims over radiating fin is more violent, the performance of heat transfer element is not fully exerted, thereby heat transfer property is good, compares with the heat transfer element that uses on the existing heat exchanger, and this monoblock type corrugated fin pipe heat transfer element Coefficient K can improve 22～40%.
(2) under the condition of transmitting identical heat, the volume and weight of this monoblock type corrugated fin pipe heat transfer element can reduce 15～39%, saves lot of materials, reduces production costs.
(3) radiating fin and heat transfer flat tube are one, need not welding, and be also without pickling industry, free from environmental pollution again when having simplified manufacturing process.
(4) shock resistance is strong, can not cause radiating fin and heat transfer flat tube to produce because vibration is violent and break away from.
Concrete structure of the present utility model is provided by accompanying drawing 1,2,3.

Accompanying drawing 2 is the left view of monoblock type corrugated fin pipe heat transfer element;
Accompanying drawing 3 is the vertical view and the details enlarged drawing of monoblock type corrugated fin pipe heat transfer element.
The specific embodiment
Below monoblock type corrugated fin pipe heat transfer element is described in detail.
This monoblock type corrugated fin pipe heat transfer element is formed (seeing accompanying drawing 1,2,3) by radiating fin 1 (seeing accompanying drawing 1,2,3) and heat transfer flat tube 2, radiating fin 1 and heat transfer flat tube 2 are one, radiating fin 1 is positioned at the upper and lower both sides of heat transfer flat tube 2, the radiating fin 1 of both sides is a bellows-shaped up and down, radiating fin 1 is vertical with heat transfer flat tube 2, and the spacing between the radiating fin 1 is S
f, radiating fin 1 thickness is δ, highly is H
p, the wavelength of ripple radiating fin 1 is L
4, wave height is H, heat transfer flat tube 2 section thicknesses are W
1, width is L
1, evenly being furnished with 2～3 not connected rectangular channels 3 (seeing accompanying drawing 1) in the heat transfer flat tube 1 vertically, rectangular channel 3 section thicknesses are W
2, width is L
2, the spacing between each rectangular channel 3 is L
3During heat transfer element work, one end of each rectangular channel 3 of the fluid that temperature is high (as water or oil) in the heat transfer flat tube 2 flows into, the other end from rectangular channel 3 flows out again, the then horizontal radiating fin 1 of plunderring outside the heat transfer flat tube 2 of the air that temperature is lower, thereby the exchange heat between the cold air of realizing flowing through the hot fluid in the heat transfer flat tube 2 and flowing through radiating fin 1.
Claims (3)
