Abstract

PURPOSE: A preventer is provided to protect an engine room from being damaged caused by heat and to increase heat emitting efficiency of a radiator. CONSTITUTION: An engine room(R) installs an engine(2) for increasing heat emitting efficiency of a radiator(1) and an inner partition(3) between the engine and the radiator. Thus, the engine room is divided into an engine chamber(R1) and a radiator chamber(R2). The radiator chamber forms an air inlet hole(5a) on an outer board(4) of a vehicle. The inner partition also forms an air inlet hole(5b) extending from a front partition(8). The air inlet hole on the outer board is extended from the radiator to more than the length of L/3. The L is the length from the front partition to the radiator. Therefore, a preventer against thermal damage inlets outer air through the outer air inlet hole(5a) and inlets inner air of the engine chamber through an inner air inlet hole(5b).

Description

ANTI- THERMAL DRMAGE STRUCTURE FOR ENGINE ROOM}

The present invention relates to an engine room thermal damage prevention structure, and more particularly, by changing the position of the air inlet inside the engine room of the bus to increase the flow rate of the external air introduced therein to prevent the thermal damage (THERMAL DAMAGE) phenomenon inside the engine room. It is related to an anti-heating structure of the engine room.

In general, an engine room of a bus is a space in which an engine, which is a main power source of a vehicle, is mounted, and a space in which not only the engine but also peripheral devices for operating the engine are installed.

In the engine room R of the bus, as shown in FIG. 2, an internal partition 53 (PARTITION) is provided between the engine 52 and the radiator 51 to improve the heat radiation efficiency of the radiator 51. It is separated into the engine chamber R1 and the radiator chamber R2, and the air inlet 55 is comprised in the vehicle body outer plate 54 of the radiator chamber R2 side.

In addition, the air inlet 55 is configured from the front partition 56 of the engine room R to the front of the radiator 51 to introduce external air for cooling the radiator 51 into the radiator chamber R2. .

At this time, the external air is introduced as the wired A (F1) and the wired B (F2), the external air introduced as the wired A (F1) acts as a vortex, and the outside is introduced with the wired B (F2) The air passes through the radiator 51 and is discharged to the lower side of the engine room R.

However, the configuration of the engine room (R) air inlet as described above interferes with the flow of external air due to vortices from the front of the radiator through the radiator to reduce the radiator heat radiation efficiency, resulting in engine temperature This results in an increase in temperature and an increase in the temperature inside the engine room, causing problems such as thermal damage to various electrical devices in the engine room.

Therefore, the present invention was created to solve the above problems, an object of the present invention is to improve the heat radiation efficiency of the radiator by changing the location of the air inlet and adding to improve the streamline of the outside air flowing into the engine room, It is to provide an engine room thermal deterioration structure to prevent thermal deterioration in the engine room.

In the engine room thermal damage prevention structure according to the present invention in order to realize this, the engine room (R) is separated into the engine chamber and the radiator chamber by an internal partition, and in the engine room thermal damage prevention structure formed by configuring an air inlet,

An outer air inlet configured on the radiator chamber side body shell to a position where the air inlet is spaced a predetermined distance from the radiator in the front partition of the engine room R;

And an inner air inlet formed in a predetermined length in front of the inner partition.

Therefore, the outside air inlet is introduced into the outside air as the streamline C (F3), the inside air inlet is introduced into the internal air of the engine chamber like the streamline D (F4).

BEST MODE Hereinafter, preferred configurations and operations of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic view showing the flow field of the engine room and the inlet air of the bus according to the present invention, the engine room (R) of the bus to improve the heat dissipation efficiency of the radiator (1) and the radiator ( 1) The internal partition (3, PARTITION) is installed between the engine chamber (R1) and the radiator chamber (R2) is separated, the radiator chamber (R2) side of the vehicle body outer plate (4) is formed with an air inlet (5a).

In the internal partition 3 between the engine 2 and the radiator 1, an air inlet 5b having a predetermined length L1 is formed from the front partition 8 of the engine room R.

In addition, the air inlet 5a formed in the vehicle body shell 4 is located at least L / 3 away from the radiator 1 with respect to the distance L from the front partition 8 of the engine room R to the radiator 1. It is composed until.

The engine room thermal damage prevention structure by such a configuration introduces external air through the outer air inlet 5a as in the streamline C (F3), and streams the internal air of the engine chamber R1 through the inner air inlet 5b. It will flow as (F4).

Accordingly, in the radiator chamber R2, vortices do not occur when the outside air is introduced through the outer air inlet 5a, so that the flow rate passing through the radiator 1 increases, and the engine chamber through the inner air inlet 5b. Since the hot air inside the R1 is removed, fresh outside air is supplied from the lower side of the vehicle body to the engine chamber R1 to prevent thermal degradation of various electric devices due to the temperature rise in the engine room R. .

As described above, the engine room thermal damage prevention structure according to the present invention prevents the generation of vortices in the radiator chamber by changing and adding the position of the air inlet for introducing external air into the engine room, thereby increasing the flow rate through the radiator. By improving the thermal efficiency and discharging the hot air in the engine chamber, it is possible to prevent the thermal deterioration phenomenon of various electric devices due to the temperature rise in the engine room (R).

In addition, since the temperature of the engine room is low, heat inflow is reduced to the interior of the vehicle, and in particular, it has the advantage of maintaining a comfortable indoor temperature in summer.
