Abstract

An evaporator assembly included an annular frame (10) which is adapted to be fixed on a car air conditioner. An evaporating tube unit (11) is fixed and distributed evenly within the frame (10). A plurality of heat exchange fins (12) are secured to the evaporating tube unit (11). An air filter (20) is installed within the frame (10) and is adjacent to the evaporating tube unit (11) and the heat exchange fins (12). The air filter comprises two axially spaced-apart air permeable nonwoven fabrics (24), the space being subdivided into a plurality of hexagonal chambers (22). Each chamber is filled with active carbon grains (23). <IMAGE>

Description

TITLE: EVAPORATOR ASSEMBLY FOR A CAR AIR CONDITIONER This invention relates to an evaporator assembly for a car air conditioner, more particuraly to an evaporator assembly which is capable of filtering air that is to be supplied by the car air conditioner.
Referring to Fig.l, a conventional evaporator assembly 1 for a car air conditioner is shown to have a plurality of evaporating tube units (la) which are fixed and distributed evenly within the assembly 1 and which are adapted to permit passage of a refrigerant therethrough (not shown), and a plurality of heat exchange fins (lob) which are secured to the evaporating tube unit (la) and which are distributed evenly within the assembly 1 so as to perform heat exchange between air flowing through the car air conditioner and the refrigerant. The refrigerant absorbs heat from the air which flows into the evaporator assembly 1 so as to cool the air. Note that if a passenger is smoking inside the car, air in the latter is circulated by the air conditioner without filtering the same.
Therefore, the main object of this invention is to provide an evaporator assembly for a car air conditioner which can improve the quality of air inside a car that is installed with the air conditioner.
According to this invention, an evaporator assembly includes an annular frame which is adapted to be fixed on a car air conditioner so as to act as a passage for air flowing into and away from the air conditioner. An evaporating tube unit is fixed and distributed evenly within the frame and is adapted to permit passage of a refrigerant therethrough. A plurality of heat exchange fins are secured to the evaporating tube unit and are distributed evenly within the frame so as to perform heat exchange between air and the refrigerant. An air filter is installed within the frame and is adjacent to the evaporating tube unit and the heat exchange fins in such a manner that the evaporating tube unit and the heat exchange fins are located on the same side of the air filter. The annular frame defines an interior hole therein.The air filter includes two axially spaced-apart air permeable nonwoven fabrics which are secured within the frame and which close the interior hole of the frame, and a filtering material which is made of active carbon grains that fill in a space defined between the nonwoven fabrics.
Other features and advantages of this invention will become apparent in the following detailed description of the preferred embodiment of this invention with reference to the accompanying drawings, in which: FIG. 1 is a sectional view of a conventional evaporator assembly; FIG. 2 is an exploded view of an evaporator assembly of the present invention; and FIG. 3 is a schematic view illustrating the evaporator assembly of this invention.
Referring to Figs. 1 and 2, the preferred embodiment of an evoparator assembly according to the present invention is shown to include an annular frame 10 adapted to be fixed on a car air conditioner (not shown) so as to act as a passage for air flowing into and away from the air conditioner. The annular frame 10 has several threaded holes 14 which are formed in a periphery thereof. An evaporating tube unit 11 is fixed and distributed evenly within the frame 10 and is adapted to permit passage of a refrigerant (not shown) therethrough. A plurality of heat exchange fins 12 are secured to the evaporating tube unit 11 and is distributed evenly within the frame 10 so as to perform heat exchange between air and the refrigerant. An air filter 20 has several locking ears 21 which are aligned with the threaded holes 14 of the frame.Bolts 30 extend through the locking ears 21 and engage respectively the threaded holes 14 so as to mount the the filter 20 on the annular frame 10. The air filter 20 is installed within the frame 10 and is adjacent to the evaporating tube unit 11 and the heat exchange fins 12 in such a manner that the evaporating tube unit 11 and the heat exchange fins are located on the same side of the air filter 20. The annular frame 10 defines an interior hole 13 therein. The air filter 20 includes two axially spaced-apart air permeable nonwoven fabrics 24 which are secured within the frame 10 and which close the interior hole 13 of the frame 10. The fabrics 24 cooperatively confine a space therebetween, which space is devided into a plurality of hexagonal chambers 22.The air filter 20 further has a filtering material which is made of active carbon grains 23 that fill in the hexagonal chambers 22.
As illustrated in Fig. 3, the air which flows through the evaporator assembly 10 passes through the nonwoven fabrics 24 which filter the dust from the air and through the active carbon grains 23 which can absorb and filter the odors in the air.
Preferably, the filter 20 is installed at a front side of the evaporator assembly 10 which is closer to the inlet (not shown) of the air conditioner.
Note that as air passes through the evaporating tube unit 11, the water particles of the air condense on the heat exchange fins 12. Thus, if the filter 20 was installed at the rear side of the evaporator assembly 10, water may accummulate on the surface of the fabrics 24, or may be absorbed by the active carbon grains 23, thereby affecting the filtering efficiency of the filter 20.
