Diesel engine radiator with detachable cover and lower part

The invention is a set water tank on the diesel engine of evaporative type cooling.Cooling water required during the diesel engine operation adds water tank, and when diesel engine moved, the heat that is produced distributed by the evaporation of the water in the water tank.

The water tank of existing evaporative type cooling diesel engine, useful steel plate is made, also useful aluminium alloy casting.A large amount of single cylinder small diesel engines that use in the rural area particularly in the society, most of aluminium alloy casting water tank that uses, the aluminum alloy water tank is easy to heat radiation than steel plate water tank, also corrosion-resistant than steel plate water tank, but casting water tank technology is complicated, and efficient is lower, and the tightness of foundry goods and anti-water-leaking property are poor slightly.In order to save aluminum feedstock, enhance productivity, make water tank more attractive in appearance, the die casting aluminium water tank has appearred in recent years.Because the design of die casting water tank fails to throw off the pattern of original casting water tank, adopts a water tank to divide two housing sections die casting, is welded into a finished product water tank then altogether.Produced like this die casting water tank, the aluminum alloy tightness is better than casting water tank, the water tank wall thickness rate is cast the water tank attenuate and the anti-casting water tank that can surpass of intensity, but the welding in the manufacturing process is difficulty, efficient is not high yet, also unfavorable to the working life under the big environment of long-term vibration difference variation, influence the die casting water tank and substituted the process of casting water tank.

The purpose of the invention is the evaporative type cooling diesel engine radiator of creating shape, constructing and be combined with new technical characterstic, this water tank need not weld and form the integrated water tank housing, but become an integrated water tank with lower body with fastening piece assembling tank upper cover, avoid welding deformation, enhance productivity, increase water tank intensity, increase the service life, and be easy to make more attractive in appearancely.

Former integrated water tank is divided into loam cake in the invention and two parts of lower body are made, and with fastening piece loam cake and two parts of lower body is assembled together complete tank shell of formation then.

The invention is compared with existing casting water tank, can reduce the difficulty of casting and molding, is particularly conducive to be applied in the die-casting process and goes.Existing die casting water tank also is to be divided into two body die casting, uses welding will go up lower body and is welded into an integrated water tank, and this technology, long processing time, complex process, cost is higher, is unfavorable for large quantities of manufacturings and large-scale application.Water tank is divided into loam cake in the invention and lower body is made respectively, make as lower body integral body, not leakiness is filled with water, and the junction plane of loam cake and lower body is as being in the last planar line of water tank cavity, after connecting tight loam cake and lower body with fastening piece, sealing is not subjected to the pressure of big water, add be coated with sealer or lay leakproofing materials such as cushion rubber, packing paper plate after, can prevent that the water in the water tank from spilling water tank.Existing water tank is general owing to will carry out being linked and packed of water tank and body, leave big window at water tank upper,, on window, load onto tank funnel again loading water tank after on the body, generally refill the height that float shows water level on the tank funnel, so that observe SEA LEVEL VARIATION.The funnel that both can keep existing water tank above the tank upper cover of face the invention is the design proposal that gets on of assembling in addition, tank funnel and tank upper cover can be designed to the one one-step die casting again, and good integrity attractive in appearance can be saved manufacture cost again.The water tank lower body is installed to body when getting on, and top is unlimited fully, is convenient to assembly manipulation.As making the invention water tank, same advantage and good effect are arranged also with injection molding forming method.

Description of drawings:

Filler 2 is arranged on the tank upper cover 1, and the window 4 of water tank lower body 3 bottoms communicates with the cooling water of body 5 inside.Pack in hole 6, hole 7, hole 8, hole 9, hole 10, the hole 11 behind the fastening piece, loam cake 1 and lower body 3 can be connected into an integrated water tank.Hole 10, hole 11 can also be simultaneously as lifting bolt being installed, being tightened up fuel tank etc.Quantity in hole of fastening piece of packing into and position and fastening means can increase and decrease quantity and selection coordinate position flexibly according to water tank size and needs attractive in appearance.The shape of water tank can be designed to flatly shallowly low also can be designed to various stero shapes such as sphere so that the more economical practicality of capacity, and outward appearance and diesel engine integral body are more coordinated attractive in appearance.

The best way that realizes the invention is to be used for aluminium alloy compression casting water tank, aluminium alloy plate punching press water tank or high-temperature resistance plastice water tank.Selecting bolt and nut to connect fastening tank upper cover becomes a completed cases with lower body and is easy to install and remove.Can on water tank lower body outer wall, arrange perpendicular grooves, improve tank box intensity and rigidity.Water tank lower body bead suitable for reading place is provided with perforation just can pass connecting bolt, and groove shapes and nut profile coupling can conveniently tight a bolt, and can play locking effect again.The Draft that water tank die casting or punching press must design reduces volume in the time of can looking after the blank transportation simultaneously and takies the requirement that intussusception is stacked, and the business efficiency that improves long-distance transportation reduces traffic-induced damage again.The water tank lower body also can be designed to the smooth surface smoothness and not arrange groove, and cavity arrangements corresponding to the boss of loam cake perforation so that tight a bolt usefulness when making inner bolt hole for the assembling integrated water tank.Also can adopt tank outer wall to arrange the fastening scheme that groove and cavity arrangements inner bolt hole boss combine.Also can select for use other fastening pieces such as easy-to-dismount rivet to connect tank upper cover and lower body becomes an integrated water tank.Tank upper cover and lower body junction plane adopt various sealing materials such as sealer, cushion rubber, packing paper plate to carry out the leakproof water-stop, can freely select loam cake and lower body junction plane in the residing on the whole position of water tank when design.Loam cake and lower body junction plane can be arranged in water tank upper as far as possible, also can wish and put in water tank below the water surface curve, the water tank bottom even at water tank middle part, the combining the plane and can horizontal arrangement also can be in tilted layout and asymmetric arrangement of loam cake and lower body, with look after diesel engine integral body both artistic and practical, mounting or dismounting are convenient, save many-sided requirements such as cost.The punching press water tank that the invention is applied to the sheet metal making gets on to have more tangible good effect, can arrange to stamp out stiffening rib and pictorial trademark etc. by corresponding stiffening rib on loam cake and lower body, is suitable for especially making of the aluminum alloy plate materials punching press.Must be when diesel engine is sold with the toolbox of joining, the instrument, operating instruction, rapid wear Component of mounting or dismounting diesel engine etc. are housed in the case, former this toolbox can only separate with the diesel engine body.As closely there not being packing shipping diesel engine, transportation is placed in the toolbox in addition, and is more fragile even lose.After using the invention water tank, toolbox and the supporting design of water tank cavity can be contained in water tank the inside shipping at random with the toolbox, thoroughly solve the toolbox and be free on the difficult problem that rapid wear is easily stolen outside the diesel engine body.
