Compressor of an air conditioner of a car with capability to
dissipate heat produced by itself
Abstract
A compressor of an air conditioner of an automobile consists of
a main body, a circular electromagnet fixedly disposed around a
sleeve of the main body, a rotary wheel rotary about a sleeve
fixedly disposed around the shaft, and a co-moving disk connected
to the shaft; the co-moving disk can be attracted onto the wheel so
as to rotate together with the wheel to cause the shaft of the main
body to rotate when the electromagnet is powered, thus making the
compressor function; the rotary wheel is formed with several vent
holes near to an edge thereof for allowing airflow caused by
rotation of the wheel to pass onto the main body as well as blades
next to respective ones of the vent holes thereof for increasing
rate of flow of air through the vent holes onto the main body.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a compressor of an air
conditioner of an automobile with capability to dissipate heat of
itself, more particularly one, of which a rotary wheel is formed
with vent holes and blades, so that air flow rate increases to
dissipate heat of the compressor more rapidly due to rotation of
the rotary wheel when the compressor is working.
[0003] 2. Brief Description of the Prior Art
[0004] Air conditioners of automobiles are equipped with
compressors and other mechanisms, which cooperate to produce cool
air.
[0005] Referring to FIGS. 4, and 5, a conventional compressor of an
automobile consists of a main body 1, an electromagnet 2, a rotary
wheel 3, and a co-moving disk 4. The main body 1 has a connecting
shaft 12 connected to inner parts (not shown) thereof, and a sleeve
11 fixedly disposed around the shaft 12. The electromagnet 2 is
circular, and is fixedly disposed around the sleeve 11 on the main
body 1. The rotary wheel 3 has a hole 31 on the middle, a bearing
32 fitted in the middle hole 31, and a circular trench 33 on an
inward side thereof. The rotary wheel 3 is turnably connected to
the main body 1 with the bearing 32 being connected to the sleeve
11, and with the electromagnet 2 being received in the circular
trench 33. The co-moving disk 4 can be attracted by magnets, and
has a middle tube 41. The co-moving disk 4 is arranged next to the
rotary wheel 3, and connected to the connecting shaft 11 of the
main body 1 at the middle tube 41.
[0006] Referring to FIGS. 4 to 6, a belt 51 is passed over the
rotary wheel 3 and a rotary element of a motor 5. And, the motor 5,
and the electromagnet 2 are powered so that the rotary wheel 3 is
made to rotate by the motor 5, and the co-moving disk 4 is
attracted onto the rotary wheel 3 by means of magnetic force of the
electromagnet 2. Thus, the co-moving disk 4 rotates together with
the wheel 3 to make the shaft 12 of the main body 1 to turn, and in
turns, the compressor functions.
[0007] It can be seen that the above compressor is not equipped
with any device for dissipating heat produced by it, and the heat
is dissipated only by air that moves through the car when the car
is driven. In other words, heat of the compressor can't be rapidly
dissipated in case the compressor is working while people are
resting in the car without driving.
SUMMARY OF THE INVENTION
[0008] It is a main object of the present invention to provide a
compressor of an air conditioner of an automobile, which can
effectively dissipate heat produced by it when it is working.
[0009] The compressor of the present invention has a rotary wheel,
which is connected to a motor by means of a belt to pass on
movement of the motor to other parts of the compressor, and which
is formed with several vent holes near to the edge for allowing
airflow caused by rotation of the wheel to pass onto a main body of
the compressor, and blades next to respective ones of the vent
holes thereof for increasing rate of flow of air through the vent
holes onto the main body of the compressor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0017] Referring to FIGS. 1, and 2, a preferred embodiment of a
compressor of an air conditioner of an automobile in the present
invention includes a main body 1, an electromagnet 2, a rotary
wheel 6, and a co-moving disk 4.
[0018] The main body 1 has a connecting shaft 12 connected to inner
parts (not shown) thereof, and a sleeve 11 fixedly disposed around
the shaft 12. The electromagnet 2 is circular, and is fixedly
disposed around the sleeve 11 on the main body 1. The rotary wheel
6 has a hole 61 on the middle, a bearing 62 fitted in the middle
hole 61. The rotary wheel 6 is arranged next to the electromagnet
2, and turnably connected to the main body 1 with the bearing 62
being connected to the sleeve 11. Furthermore, the rotary wheel 6
is formed with several sloping vent holes 63 near to the edge
thereof, and blades 64 next to respective ones of the sloping vent
holes 63.
[0019] The co-moving disk 4 can be attracted by magnets, and has a
middle tube 41. The co-moving disk 4 is arranged next to the rotary
wheel 6, and connected to the connecting shaft 11 of the main body
1 at the middle tube 41.
[0020] Referring to FIG. 3, to use the compressor, a belt 51 is
passed over the rotary wheel 6 and a rotary element of a motor 5.
And, the motor 5, and the electromagnet 2 are powered so that the
rotary wheel 6 is made to rotate by means of the motor 5, and the
co-moving disk 4 is attracted onto the rotary wheel 3 by means of
magnetic force of the electromagnet 2. Consequently, the co-moving
disk 4 rotates together with the wheel 6 to make the shaft 12 of
the main body 1 to turn, and in turns, the compressor functions.
And, increased proportion of airflow that is caused by rotation of
the wheel 6 can pass onto the main body 1 due to the vent holes 63;
thus, heat of the main body 1 can be rapidly dissipated. In
addition, more air is made to flow through the vent holes 63 of the
rotary wheel 6 onto the main body 1 by means of the blades 64, and
in turns, heat produced by the main body 1 can be dissipated still
more rapidly.
[0021] From the above description, it can be easily understood that
the compressor of the present invention has advantages as
followings:
[0022] 1. Airflow caused by rotation of the wheel 6 is allowed to
pass onto the main body 1 at larger proportion due to the vent
holes 63. Therefore, heat of the main body 1 can be dissipated
rapidly.
[0023] 2. The rate of flow of air through the vent holes 63 of the
rotary wheel 6 onto the main body 1 is increased by means of the
blades 64 therefore heat produced by the main body 1 can be
dissipated still more rapidly.
