Description

The internal combustion locomotive cooler

Technical field:

The utility model is relevant with the cooling unit of internal combustion locomotive.

Technical background:

Existing internal combustion locomotive cooler has the plate-tube type structure, the cooling medium water, and there are flat tube and garden pipe in the water-cooling tube cross section in the tube-plate intercooler.Porose on the cooling fin.The heat conduction reinforced mechanism of cooler belongs to the destruction boundary layer and comes augmentation of heat transfer.The heat transfer efficiency height.

The content of model utility:

The purpose of this utility model provides a kind of simple in structure, and is easy to manufacture, and cost of production is low, long service life, the internal combustion locomotive cooler that heat transfer efficiency is high.

The utility model is achieved in that

The utility model internal combustion locomotive cooler comprises the water pipe 2 that the hole 1 of passing cooling fin 7 is connected with it, the tube sheet 3,4 that is connected with water pipe 2, have on the cooling fin 7 tri-angle-holed 8,7 one-tenth angles of triangle fin 9 and cooling fin, it links to each other with cooling fin 7 on one side.

The utility model hole 1 is shape hole, garden, and its periphery has two triangle fins 9, tri-angle-holed 8 and the triangle fin be that punching out forms on cooling fin.Triangle fin 9 and cooling fin 7 are at an angle of 90.

The utility model hole 1 is a slotted hole, and its periphery has four triangle fins 9, tri-angle-holed 8 and the triangle fin be that punching out forms on cooling fin.Triangle fin 9 and cooling fin 7 are at an angle of 90.

The novel two triangle fin of this usefulness 9 is 25 °～60 ° with the tangent line angle in hole 1, the line of one end and hole 1 tangent and with the equal diameters in hole 1.

The utility model triangle fin 9 is 20 °～40 ° with the long limit angle of slotted hole 1, and the one end lays respectively on the end line and middle part line of slotted hole 1.

The upper and lower two row's slotted holes 1 of the utility model are staggered, and last row's hole is on the center line of arranging down between two holes.

The 1 horizontal and vertical alignment of shape hole, the utility model garden is arranged, and triangle fin 9 is a right-angled triangle, and its right angle side that links to each other with cooling fin is 1～4mm, and another right angle side is 1～2mm.

Shape hole, the utility model garden 1 is staggered, and the garden bore dia is 10～14mm, and triangle fin 9 is a right-angled triangle, and its right angle side that links to each other with cooling fin is 2～4mm, and another right angle side is 1～2mm.

The tri-angle-holed g of the utility model and triangle fin 9 punching out on cooling fin form, hole 1 is connected with mechanical expanded joint of water pipe 2 usefulness or soldering, water pipe 2 is connected with tube sheet mechanical expanded joint of 3,4 usefulness or soldering, and tube sheet 3,4 is connected with water cover 5,6 usefulness bolts, is provided with water tank in the water cover 5,6.

Tri-angle-holed and the triangle fin of the utility model punching out on cooling fin makes air produce rotational flow around main flow direction, thereby has strengthened nearly plate face and away from the mutual mixing of plate surface current body, improved heat transfer intensity.Its cooling reinforcing mechanism is: the powerful vortex air flow that the upright thorn of making according to pressurized air airflow passes cooling fin upper punch of triangle is produced, attenuate or elimination cooling fin surface gas boundary layer, thereby greatly improve the temperature conductivity of cooler, water pipe replaces original flat tube with the garden pipe, connect technology and change end process of tin or mechanical expanded joint into, pipe, slice, thin piece burning when having solved original welding, the difficult problem of poor reliability.The utility model is simple in structure, and is easy to manufacture, shows its heat-transfer coefficient (199.53KW), heat dissipating capacity (388.53W/W through stand test ²K), loss of air pressur item performance index such as (4819Pa) can satisfy the performance requirement of diesel engine of locomotive fully, and under the suitable situation of heat dissipating capacity, pressure loss value reduces about 10% than other like product.
