Abstract

PURPOSE:To effectively prevent overheat in a device used for a forklift truck or the like, by forming a ventilative passage to a counterweight behind an engine compartment and arranging a radiator and electric motor driven blower. CONSTITUTION:A forklift truck 1 is formed such that an engine compartment 3 is equipped under a driver's seat 6 further a counterweight 4 is arranged behind these seat and engine compartment. Here a cavity part 8 is formed throughout from the upper to the rear of the counterweight 4 in such a manner as to be communicated to the outside of a car, while a ventilative passage 9 is constituted by partitioning the cavity part 8 and the engine compartment 3 through a separator plate 7. Then an engine radiator 10 is arranged in the vicinity of an upper side of the counterweight 4 in the passage 9, further an electric motor driven blower 11 of suction type is arranged below the radiator 10 through a fan shroud S. In this way, hot air after flowing through the radiator 10 can not be introduced into the engine compartment 3 but led out to the outside of the car to attain the desired end.

Description

[Detailed Description of the Invention] coIJkl! Reference numeral 311 relates to an engine radiator cooling system in an industrial vehicle such as a forklift truck.

In general, in industrial vehicles such as forklift trucks, the machine lBl engine is located at the rear of the engine. A suction or discharge type fan, which is installed and driven by the rotation of the engine, is used to pump air outside the vehicle. ! The air in the engine room is passed through two radiators to cool the engine cooling water. In addition, even if you can use a counterweight or a discharge type fan, the air for cooling the Kugiator is mounted on the KIF at the rear of the vehicle body and is opened to the rear of the K vehicle. The air is sucked in through the pores formed in the air, and the cooled air is exhaled.

In the 40 type, the air inside the engine room is passed through the air in the engine room using a blow-out type fan, and the cooled air is discharged to the rear of the carrantau. The rounded KIl of cooling the air that xm air dfcA! The heat exchange efficiency of Uyome Fujiator is low.
There is a risk that the I will overheat, and the air in the engine room and the dust from the road will be drawn in and clog the 2 radiator, which will further promote overheating. There is a problem that the inside of the engine room becomes contaminated and the life of the engine and machinery/auxiliary equipment is shortened.The fugiator is cooled by introducing outside air using a suction type fan, and cools the fugiator with cold #* air. In the case of the type that leads into the engine room, the outside air is introduced into the engine room after heat exchange with the radiator.
The normal operating performance of the engine is hindered (9), and the hot air
The problem frequently occurred that the seat area became extremely hot, making the operator feel uncomfortable and not desirable for safe work.

This invention is designed to solve the problem of conventional problems, effectively prevent overheating, and repair the engine and machinery! Tsujie can extend the lifespan of Class S by 10,000% and contribute to safe work by preventing the discomfort caused by m*! The purpose is to provide a cooling device.

In order to achieve the above object, this invention forms an air passage partitioned off from the engine room at the rear of the engine room, and extends the opening of this air passage from above the counterweight to the counterweight 0*7jK. Yo [
11 belongs to this O air passage K11ll Tsujieme and electric blower &! The system is designed so that outside air is circulated through the ventilation path by driving a blower, and the passing air cools the two radiators.

The embodiment shown in Figure rIi will be described below.

In the diagram, 1 is the car body, 2 is the nine engines installed in the engine room 3, which is formed by a single unit L, and 4 is the car body 1.
Counterweight mounted on 1m11, 5 is above engine room 3! 6 is an operator's seat placed on the upper surface of the top panel 5, 7Fi is a partition for the engine roux A3], is formed in the power unit weight 4, and is formed on the 9th part 8. l
In the partition plate forming s9, the ventilation passage 9 communicates with the outside of the vehicle from above the counterweight to behind the counterweight. A 411 related fan IO is disposed near the upper side of the counterweight of the ventilation passage 90, and an electric blower 11 with a suction 1i is disposed below this 2 radiator/IO via a fan shield 8.
The opening section 1 on the upper side of the counterweight of the ventilation passage 9 is disposed behind the top panel 50 and covered by a nine looper 12, in which an opening $12m is formed along the rear of the vehicle.

With this configuration), by the rotation of the electric blower 11, outside air is introduced into the ventilation passage 9 from the air conditioner through the opening 12a, passes through the fugiator 10, and the cooling island is exchanged here. This heat exchange air is discharged to the outside of the vehicle through the lower side opening of the vent at the rear of the counterweight 4 (@913).

Therefore, after passing through the radio ink, the hot air is not introduced into the engine compartment but is discharged outside the vehicle, so that the hot air does not accumulate in the engine compartment 3 and does not adversely affect the operating performance of the engine 20. Moreover, the area under the seat 6 will not become hot and cause discomfort to the operator.In addition, since outside air is introduced above the counterweight 40, the fugiator may become clogged and the engine 2 may overheat. Since the engine 2 and the engine auxiliary equipment are not contaminated, the service life of the engine 2 and the engine auxiliary equipment is extended, which is a great practical effect.

It was JI! Round 2 radiator 100 that directly introduces outside air into
A round fugiator 10 with improved cooling efficiency and whose upper opening 9a is covered by a looper! ! -9 There is no need to do it, and looper 120111I mouth 11
Since the i2 &# vehicle is facing the rear, the noise level at the operator's ear position is low. ―
Then, at the bottom 11 of the top panel 50, one end 13&
A duct (5131) opens into the engine room 3 and the other end (5131) opens upstream of the radiator IO of the ventilation path 9.
The air inside the engine room is also introduced into the ventilation passage 9 to ventilate the engine compartment, thereby more effectively preventing the temperature of the seat 60 (underneath the seat 60) from rising above the outside.

FIG. 3 shows still another embodiment, and is similar to FIG. 1.

To explain only the configuration that is different from the embodiment shown in FIG. It is covered by the partition [15] to ventilate the engine room 3. As is clear from the above explanation, according to the K05AK14, the radiator cooling performance m is fully exhibited and the engine overheat is prevented. This has the effect of increasing the life of the engine and the side of the engine, and preventing the seat from becoming too hot, making it useful for safe work.
