Abstract
The utility model discloses a heat radiator for a trailing type concrete pump supercharged diesel engine. The heat radiator comprises a fan driven by the diesel engine, and an intercooler and a water radiator arranged in front of the fan, wherein the intercooler and the water radiator are arranged side by side. The heat radiator for the trailing type concrete pump supercharged diesel engine has the advantages of reducing the cooling air drag, reducing the cooling air initial temperature of the heat radiator, and working normally in a high-temperature environment.
Description
Technical field
The utility model relates to the supercharged diesel engine heat dissipation technology of towed concrete pump under the hot environment, relates in particular to towed concrete pump supercharged diesel engine sink.
Background technique
At present, be the towed concrete pump of power with the diesel engine, general design uses high ambient temperature about 45 ℃.As shown in Figure 1, existing towed concrete pump supercharged diesel engine sink is generally combined by water radiator 5 and intercooler 4 these two radiators, and water radiator 5 is used for the heat radiation of the cooling circulating water of diesel engine 2; Intercooler 4 is used for the inlet air after the supercharging is cooled off, being beneficial to diesel engine 2 improves air inflow and reduces heat load, two radiator tandems together, drive blowing type fan 3 by diesel engine 2, adopt the blowing cooling, on the towed concrete pump hood of wind outlet, offer fixing venetian blind 7.Its working principle: by diesel engine 2 drive blowing type fans 3, produce cooling air 6, wind direction behind cooling air 6 process diesel engines 2 surfaces, cools off intercooler 4 earlier shown in arrow among Fig. 1, and cooling water radiator 5 again, after venetian blind 7 discharges.In the desert and the torrid areas, ambient temperature often reaches more than 50 ℃, existing sink working efficiency is low, it mainly is following two reasons by analysis: 1, construction for heat radiating device Layout Problem, two radiators adopt " series connection " formulas layouts, the towed concrete pump hood be again fix, can't open the resistance that this is bigger to the mobile generation of cooling air 6, cause the flow of cooling air 6 to reduce, heat dissipating capacity reduces; 2, wind direction problem, the cooling air 6 that existing sink produces is through behind the hot surface of diesel engine 1, about 10 ℃ of temperature rises, through behind the intercooler 4, temperature rise is more than 20 ℃, the air temperature of last cooling water radiator 5 reaches more than 80 ℃, cause cooling effectiveness low, water radiator 5 can't effectively be cooled off, and finally causes the cooling water boiling of boiling, cause diesel engine 2 overheated, cisco unity malfunction.
The model utility content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of cooling air initial temperature that has reduced the cooling air resistance, reduced radiator, can be in hot environment the towed concrete pump supercharged diesel engine sink of proper functioning.
For solving the problems of the technologies described above, the utility model by the following technical solutions.
A kind of towed concrete pump supercharged diesel engine sink comprises by diesel-driven fan, is installed in intercooler and water radiator before the fan, and described intercooler and water radiator are arranged side by side.
The upper and lower layout of described intercooler and water radiator is formed a row, and intercooler, lower disposed water radiator are arranged in top.
Described fan is the air drafting type fan.
Compared with prior art, advantage of the present utility model just is:
1, do not changing the product configuration, do not increasing under the prerequisite of product cost, change the radiator combining form, intercooler and water radiator are arranged side by side, cooling air is blown on intercooler and the water radiator simultaneously, reach the purpose that reduces the cooling air resistance, increases the cooling air flow, simultaneously, blown to the temperature rise that cooling air on the water radiator does not pass through intercooler, reduced the cooling air temperature of cooling water radiator relatively, the cooling work efficient of water radiator is improved;
2, change the flow direction of cooling air, use air cooling radiator, thereby reduced the cooling air initial temperature of radiator, make towed concrete pump energy proper functioning under the hot environment operating mode without any heating.
Comprehensive above two measures have guaranteed diesel engine energy proper functioning under 50 ℃～55 ℃ high temperature, finally make towed concrete pump can adapt to the operating mode of hot environment.

Embodiment
As Fig. 2, shown in Figure 3, a kind of towed concrete pump supercharged diesel engine sink of the present utility model, comprise the fan 3 that drives by diesel engine 2, be installed in intercooler 4 and water radiator 5 before the fan 3, on intercooler 4 and the water radiator 5, following layout is formed a row, intercooler 4 is arranged on top, lower disposed water radiator 5, cooling air 6 can be blown on intercooler 4 and the water radiator 5 simultaneously, reached and reduced cooling air 6 resistances, increase the purpose of cooling air 6 flows, simultaneously, blow to the temperature rise that cooling air 6 on the water radiator 5 does not pass through intercooler 4, reduced the temperature of the cooling air 6 of cooling water radiator 5 relatively, the cooling work efficient of water radiator 5 is improved; Fan 3 is the air drafting type fan, has changed the flow direction of cooling air 6, uses the air cooling radiator without any heating, thereby has reduced cooling air 6 initial temperatures of radiator, makes towed concrete pump energy proper functioning under the hot environment operating mode.But towed concrete pump hood 1 can also be made as opening type,, further reduce cooling air 6 resistances, strengthen cooling effect so that when diesel engine 2 work, open towed concrete pump hood 1.Towed concrete pump supercharged diesel engine sink of the present utility model has guaranteed diesel engine 2 energy proper functioning under 50 ℃～55 ℃ high temperature, finally makes towed concrete pump can adapt to the operating mode of hot environment.
