Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cooling unit for an automobile that is attached to the ceiling of an automobile.

(Conventional technology) When installing a cooling unit on the ceiling of a car,
Conventionally, as shown in FIG. 6, for example, the roof bow C was fixed directly to the roof bow C installed on the ceiling using bolts f or the like. Since most of the weight of this type of cooling unit a is occupied by the blower and evaporator b, the cooling case g needs to be strong in order to suspend these blowers and evaporator b.
A mounting base d was formed by protruding the screwing part of the poles 1-f, and a reinforcing rib e was provided on the side of the mounting base, and the entire case was made thick.

(Problems to be Solved by the Invention) However, due to the reinforcement means for the case, the vertical dimension of the cooling unit has been increased, and the head clearance has been reduced by that amount. It was blocking me.

In addition, since the blower and evaporator are mounted on the ceiling through the case, vibrations of the blower and evaporator directly put a load on the case, which has the disadvantage of accelerating fatigue of the case.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a cooling unit for an automobile that is durable and has a large head clearance by improving the mounting structure of the cooling unit main body on the ceiling of an automobile.

(Means for Solving the Problems) However, the gist of the present invention is that one side of a cooling case housing an evaporator is opened to provide an air outlet, and the other side is provided with an air blower rotated by a motor. In the cooling unit, the evaporator in the cooling unit is suspended from a roof bow provided on the ceiling of the vehicle body, the motor of the blower is suspended from another roof bow, and the cooling case l- is attached to the ceiling of the vehicle body. This is what I did.

(Function) Therefore, since the heavy blower and evaporator of the cooling unit are directly fixed to the roof bow, no load is applied to the cooling case, and a structurally stable cooling unit can be obtained. Furthermore, since there is no need to provide reinforcing ribs or the like on the case, the cooling unit can be made thinner, and therefore the above object can be achieved without sacrificing head clearance.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 4, a cooling unit 1 is shown.

For example, the ceiling of a high-roof car such as a one-box car 2
It is attached to the front of the roof via roof bows 3a and 3b. The cooling unit 1 is comprised of a cooling case 5 that houses an evaporator 4, which is a component of a cooling cycle, and a blower 6, which will be described below, provided on one side of the cooling case 5.

The cooling case 5 is a flat segmented body, and has a dividing surface that is divided into two in the horizontal direction in order to accommodate the evaporator 4 therein. A blow-out lower is formed. And the other side (
A blower case 11 of the blower 6 (on the side opposite to the blower outlet) is integrally formed. This blower case 11 also has a dividing surface that is divided into two to accommodate the fan 12, and the dividing surface is integrated with the dividing surface of the cooling case 5 described above.

The evaporator 4 is composed of fins and tubes, and has end plates 8 on both sides thereof, and a screw hole 9.9 is formed in the upper piece 8a of the end plate 8.

This screw hole 9.9 is into which a bolt 28.28 described below is screwed.

Two blowers 6 are installed in parallel in the interior direction of the vehicle body, and drive two blower cases 11 and a fan 12 housed inside the blower cases 11, and drive the fans 12.
It consists of a motor 13 interposed between 1 and 1. As described above, the blower case 11 is integrated with the cooling case 5, and has an inlet 114 formed on the negative side thereof, and an outlet (not shown) that opens into the cooling case 5 and is connected thereto. The motor 13 that rotates the fan 12 is arranged between the blower cases 11, and how to install it.

As shown in Fig. 3, the clamping piece 1 is divided into two parts in the horizontal direction.
4a and +4b. The mounting piece 14a is connected to the upper case of the cooling case 5, and the mounting piece 14b is connected to the lower case of the cooling case 5, and both parts are connected by screws 15a and 15b. In addition, the screw 15a,
When connecting at 15b, a connecting piece 17 fixed to a bracket 16 described below is aligned with the bracket 16.

The bracket 16 is attached to the motor 13 by the connecting piece 17 fixed in the middle with a screw 20. The bracket 16 is arranged in the longitudinal direction of the vehicle body, and the roof bows 3a, 3b of the vehicle body are attached to both ends of the bracket 16. Holes 18, 19 are drilled for attachment to.

21.22 are holes formed in the roof bows 3a, 3b;
It is used to connect the bracket 16 to the roof bow 3.3, and the holes 1 to 23.24 are passed through the holes 18.19 and 21.22 from below, and then the nuts 25.26 are screwed. are combined and connected.

27.27 is a hole formed in the roof bow 3g, into which a bolt 28.28 is screwed from the hole 27.27 to the hole 9.9 from the upper blade to the lower blade, The evaporator 4 is suspended from the roof bow 3b.

29. With holes formed in the roof bows 3a and 3b,
It is used to be fixed to the frame on the vehicle body side.

In the above-described configuration, in order to attach the cooling unit 1 to the roof bows 3a, 3b, first the ports 1 to 28.2 are attached.
8 further into the hole 27.27 of the roof 3b, and then pass it through the hole 27.27 formed in the cooling case 5, and then through the hole 9.9 formed in the []-nd plate 1-8 of the evaporator 4 located inside the cooling case 5. Screw it inside. As a result, the evaporator 4 is held by the roof bow 31). Thereafter, the bolts 23, 24 are inserted into the holes 18, 19, respectively, and the holes 21 formed in the roof bows 3a, 3b are then inserted.
．． Insert into 22. Then, screw the nuts 25 and 26 onto the bolts 23 and 24. As a result, the motor 13 of the blower 6 is suspended from the roof bow 3a via the bracket 16, and the installation of the cooling case l-1 to the ceiling is completed.

According to Figure 5? A second embodiment of the invention is shown. In this embodiment, the difference from the embodiment described in iif is that the bracket 1 16 is connected to only one location of the roof bow 3a via ports 1 to 23. Mounting with the roof bow in these locations is sufficient in terms of mounting strength. The other parts are similar to the above embodiment.
Therefore, the same numbers have been assigned and explanations have been omitted.

(Effects of the Invention) As described above, according to the present invention, the heavy objects of the cooling unit installed on the ceiling, such as the evaporator and mo, are directly suspended from the roof bow, so the strength of the cooling case is not required. By eliminating the mounting base and ribs, the product can be made thinner, making it possible to secure head clearance. Moreover, the thickness can be reduced, and the weight can be reduced.
