Background technology
Work mechanism such as forklift, load wagon has powerful engine usually, will produce great amount of heat during running, therefore needs heat radiation timely.In order to realize dispelling the heat timely, work mechanism all is equipped with heat sink assembly usually, receives the cooling fluid from engine circularly, cools off, and sends engine then back to.
General heat sink assembly comprises radiator, and the radiator frame that is used to support radiator, and radiator comprises the heat radiation core body again, members such as last fluid storage compartment and following fluid storage compartment.Upper and lower fluid storage compartment is connected with the heat radiation core body at two ends up and down respectively, makes upper and lower fluid storage compartment be communicated with cooling passage fluid in the heat radiation core body so that with cooling fluid introducing and the derivation core body that dispels the heat.Upper and lower fluid storage compartment all has the conduit that is communicated with the fluid storage compartment fluid and is used for being communicated with the cooling passage of engine.Upper and lower fluid storage compartment is fixed on the radiator frame through the connected mode of bolt and so on.
Yet; Because above-mentioned radiator is the traditional connected mode through for example bolt and so on, i.e. the mode of rigidity is connected to radiator frame; So the vibration of work mechanism will through radiator frame without any filtration be delivered on the radiating component, radiator is formed infringement.Industry uses aluminium to make radiator more and more, and the intensity of aluminium is relatively low, so the infringement that vibration causes is also just more serious.
In order to reduce the infringement that causes of vibration, can being connected between radiator and radiator frame adopt some vibration reducing measures usually.For example Chinese utility model CN2508199Y has announced a kind of radiator; Comprise water inlet, last fluid storage compartment, following fluid storage compartment, delivery port, scaling hole and heat radiation pipe racks; Be lined with rubber blanket between last fluid storage compartment top cover and the last fluid storage compartment; And fix with screw, last fluid storage compartment is welded into an integral body with the side plate of following fluid storage compartment and both sides, and dispelling the heat is lined with the sponge sealing gasket between pipe racks both sides and the side plate.Although adopted rubber blanket and sponge sealing gasket in this utility model; Objectively can play the effect of some vibration dampings a little; But fix and being connected of rigidity such as welding owing to remain screw between the parts (top cover, side plate) of the parts of radiator (going up fluid storage compartment, heat radiation pipe racks) and radiator frame, so the problem of vibration can't the solution of essence ground.
