Abstract
The utility model relates to a parallel heat exchanger for an engineering machine, which relates to a heat exchanger for the engineering machine, particularly a water heat exchanger, an oil heat exchanger and a middle cooler. The utility model is characterized in that at least two groups of heat exchangers are arranged on the same windward surface of a wind scooper by a frame and are not mutually influenced and not mutually interfered, and meanwhile meet the different requirements for the temperature of different media of water, oil, gas, etc. so that the effectiveness of the heat exchange is enhanced, and meanwhile energy is saved.
Description
Technical field
The utility model relates to water-to-water heat exchanger, oil heat exchanger and the charge air cooler that the heat exchanger that a kind of engineering machinery is used, particularly engineering machinery are used.
Background technology
At present, in engineering machinery field, hydraulic transmission oil, torque-converters oil to engine cool recirculated water, hydraulic system cool off employed heat exchanger, and with the matching used charge air cooler of engine with supercharger, their integral body is cooled off the dual mode that has commonly used: a kind of is the profit composite structure, this kind structure is that oil heat exchanger is placed in the lower header of water-to-water heat exchanger, comes oil is cooled off by cooling circulating water.But the oil heat exchanger of this structure is bigger to the water temperature influence of cooling water, and because the fuse of oil heat exchanger adopts finned radiating tube usually, after long-time the use, fin stops up easily and influences radiating effect, can cause also that simultaneously the hydraulic system oil pressure raises, and influences the operate as normal of system.Another kind of mode is with water-to-water heat exchanger and oil heat exchanger, even the combination stack is assembled together before and after the charge air cooler.This structure is because the air of multilayer heat exchanger of flowing through, and whenever will increase through its temperature of one deck, and this cooling effect of heat exchanger that has just caused being placed on the back is relatively poor.Must pass through the multilayer heat exchanger owing to air simultaneously, thereby cause windage bigger, and because each layer heat exchange temperature difference causes the phase mutual interference, the cooling effect of water tank is bad, causes motor to influence its power output greatly because of water temperature in the water tank is higher.
Summary of the invention
In order to overcome numerous deficiency of existing cooling system for construction machinery, the utility model will provide the better engineering machinery of a kind of radiating effect parallel heat exchanger.
The utility model comprises wind scooper and at least two group radiators, described at least two group heat exchangers by frame arrangement on the same windward side of wind scooper.
The technical scheme that its technical problem that solves the utility model adopts is: will be used for the hydraulic transmission oil to engine cool recirculated water, hydraulic system, the heat exchanger that torque-converters oil cools off, and be arranged side by side on the same windward side with the matching used charge air cooler of engine with supercharger.Usually can be two parallel arranged or a plurality of parallel arranged, and they all have separately intake-outlet or oil inlet and outlet, can not influence each other and mutual interference mutually, can satisfy of the different requirements of different mediums such as water, oil, gas simultaneously to temperature, make the heat exchange benefit improve greatly, simultaneously can also energy conservation.
More stable for a plurality of radiators are installed, above-mentioned to be used to support the support of respectively organizing radiator be rectangular frame.
In addition, snubber block is set, plays the effect of damping and shock-absorbing going to the bottom of rectangular frame.
The utility model is as a whole, simple in structure, easy to manufacture with water-to-water heat exchanger, oil heat exchanger even charge air cooler design, and has shockproof function, can also make things convenient for the assembling of main frame when improving engineering machinery integral heat sink efficient.

Specific embodiment
As shown in Figure 1, 2, hydraulic oil heat exchanger 1 and engine cool water-to-water heat exchanger 3 are arranged on the same windward side of wind scooper 5 by rectangular frame 4 respectively.Going to the bottom of rectangular frame 4 two group 2 of snubber block is set.
As shown in Figure 3, hydraulic oil heat exchanger 1 ', engine cool water-to-water heat exchanger 3 ' and torque-converters oil heat exchanger 6 respectively by rectangular frame 4 ' be arranged in wind scooper 5 ' same windward side on.Rectangular frame 4 ' go to the bottom be provided with two group 2 of snubber block '.
As shown in Figure 4, on the same windward side that hydraulic oil heat exchanger 1 ", engine cool water-to-water heat exchanger 3 " and the matching used charge air cooler 7 of engine with supercharger " are arranged in wind scooper 5 " by rectangular frame 4 respectively.Rectangular frame 4 " go to the bottom two group 2 of snubber block is set ".
In addition, if on some engineering machinery, must adopt engine cool water-to-water heat exchanger, hydraulic oil heat exchanger, torque-converters oil heat exchanger and the matching used charge air cooler of engine with supercharger simultaneously, if simultaneously these four kinds of radiators are arranged side by side on the same windward side, may make that a front face area is excessive, adopt large diameter fan can increase the consumption of engine power.This moment, we still can adopt the two-layer composite construction in front and back, with engine cool water-to-water heat exchanger and hydraulic oil heat exchanger be arranged side by side in the first floor windward side on, and torque-converters oil radiator and charge air cooler are arranged side by side on the second layer windward side, perhaps according to concrete area of dissipation requirement, also three kinds of radiators can be placed on one deck, the another one area of dissipation requires big radiator to be placed on one deck separately.
Claims (4)
1, the parallel heat exchanger of a kind of engineering machinery comprises wind scooper and at least two group heat exchangers, it is characterized in that at least two group heat exchangers by frame arrangement on the same windward side of wind scooper.
