Abstract
The utility model relates to the technical field of the cooling of internal combustion engines, in particular to a heat exchanger core for the internal combustion engines of heavy-duty trucks, heavy-duty construction machines, buses and the like. The heat exchanger core comprises a guard plate (1), radiating tubes (2), radiating strip (3), an upper main plate and a lower main plate, wherein both ends of each radiating tube (2) and both ends of each radiating corrugated ribbon (3) are respectively fixed on the upper and the lower main plates, the guard plate (1) is arranged on the sides of theupper and the lower main plates and fixed on the upper and the lower main plates, the cross section of each radiating tube (2) is shaped like a long ellipse, and the radiating corrugated ribbons (3) are arranged on the outsides of the radiating tubes (2). When cooling medium flows through the radiating tubes (2), resistance is low, flow is quick, and the radiating effect is good; because the number of welds between the radiating tubes (2) and the main plates is less, the strength is high, the core cannot easily crack, the service life of the core is prolonged, and the core is characterized byreasonable structure, good radiating effect, high shock resistance and the like.
Description
Technical field
The utility model relates to a kind of cooling technology field of internal-combustion engine, specifically a kind of heat exchanger core that is mainly used in internal-combustion engines such as heavy truck, heavy engineering machinery or big bus car.
Background technique
Internal-combustion engine uses very extensive as a kind of dynamical power source in fields such as heavy truck, heavy engineering machinery or big bus cars.Internal-combustion engine is subjected to strong heating because parts such as cylinder liner, cylinder head, piston and valve directly contact with high-temperature fuel gas at work, and mechanical temperature is very high.This not only can cause parts intensity to reduce, and may produce very big thermal stress, and parts are damaged.High temperature also can destroy the lubricant film on the cylinder wall, makes oil ageing rotten, so that piston, piston ring and cylinder liner heavy wear, bites or adhere.In addition, too high temperature also can make the air density that enters cylinder reduce, and causes malcombustions such as pinking, pre-ignition etc.In order to guarantee normal, the running reliably of internal-combustion engine, must work under the optimum temperature situation to keep internal-combustion engine by cooler to these high temperature parts coolings.Cooler is by air-cooled two kinds of type of cooling separatory cold-peace, and the employing air is air-cooled or air-cooling type cooler as being called of cooling medium.Adopt liquid as cooling medium be called the liquid cooling cooler, general liquid cooling adopts water as cooling medium.The parts of the water cooling high temperature that the utilization of water-cooled cooler circulates than air-cooled good cooling results, when particularly being applied to powerful internal-combustion engine such as heavy truck, heavy engineering machinery or big bus car, generally all adopt the water-cooled cooler.Cooler claims heat exchanger again, and the core body that present traditional water-cooled heat exchanger uses is generally many pipes and is arranged in a row, and is arranged to many rows' form then, because the interval between many row's heat dissipating pipes is more, the vernier circulating resistance is big, and radiating effect is poor, solder joint is many, the working environment of manufacturing process complexity, particularly heavy truck, heavy industry journey machinery is more abominable, often travels under the bad environment of road conditions, the core body anti-seismic performance of this structure is low, easy to crack or the fracture, the leak-down rate height influences radiating effect.
Summary of the invention
In order to overcome above-mentioned defective, it is a kind of rational in infrastructure that the utility model provides, good heat dissipation effect, intensity height, the core body of the internal combustion engine heat exchanger that anti-seismic performance is high.
The technical solution adopted in the utility model is: a kind of internal combustion engine heat exchanger core body, comprise backplate, heat dissipating pipe, heat-radiation belt and upper and lower mainboard, fixedly connected with upper and lower mainboard respectively in the two ends of heat dissipating pipe and heat-radiation belt, backplate is arranged on a side of upper and lower mainboard and fixedlys connected with upper and lower mainboard, described heat dissipating pipe cross section is an oblong, distributing in the pipe is provided with curved stiffening plate, and the dual-side of stiffening plate is connected with the tube wall of heat dissipating pipe, and described heat-radiation belt is arranged on the heat dissipating pipe outside.
Described stiffening plate is an arc.
Described stiffening plate is " V " shape.
The utility model is arranged to a tube multi-channel formula structure by stiffening plate with heat dissipating pipe, and when cooling medium was flowed through the heat dissipating pipe of this structure, resistance was little, and circulation is fast, good heat dissipation effect; The solder joint of heat dissipating pipe and mainboard is few, and the intensity height is not easy to crack, improves the working life of core body; Curved stiffening plate can strengthen heat diffusion area, improves radiating effect, also increases support strength.

Embodiment
Now in conjunction with the accompanying drawings the utility model is further described, Fig. 1 is an embodiment of the present utility model, mainly comprises heat dissipating pipe 2, heat-radiation belt 3, backplate 1, goes up mainboard 5 and following mainboard 6 etc.Described heat-radiation belt 3 is arranged on the outside of heat dissipating pipe 2, and is arranged in order, and fixedlys connected with upper and lower mainboard respectively in the two ends of heat dissipating pipe 2 and heat-radiation belt 3, and backplate 1 is arranged on a side of upper and lower mainboard and fixedlys connected with upper and lower mainboard.Described heat dissipating pipe 2 cross sections are oblong, and distributing in the pipe is provided with curved stiffening plate 4, and the dual-side of stiffening plate 4 is connected with the tube wall of heat dissipating pipe 2, and stiffening plate 4 is divided into some passages with heat dissipating pipe 2.Stiffening plate 4 in the present embodiment is an arc, is parellel and arranges, and sees Fig. 2.
During use, be subjected to the control of cooling system to make the hot water in the upper header flow to lower header at the heat dissipating pipe 2 that flows through core body, after water enters heat dissipating pipe 2, its heat is constantly absorbed by heat dissipating pipe 2 tube walls and curved stiffening plate 4, and pass to the outer wall of heat dissipating pipe 2 continuously, on heat-radiation belt 3, by flow air heat is taken in the atmosphere again and go, reach the purpose of cooling, heat radiation.
The utility model embodiment 2 except the shape of stiffening plate 4 with embodiment is different, all the other technological schemes are all identical with embodiment 1, the stiffening plate 4 among the embodiment 2 is " V " shape structure, sees Fig. 3.Stiffening plate 4 of the present utility model can also be other conspicuous shape, as waveform etc.
The utlity model has rational in infrastructure, good heat dissipation effect, intensity height, anti-seismic performance high.
