Description of the Related Art Generally, an air-conditioning case is composed of a pair of upper and lower cases formed by resin molding, and these cases are partly formed in conformity with the shape of the evaporator as disclosed in Japanese Utility Model Publication No. 62-8165. The evaporator is pushed in or the locking wall is projectingly provided on the inner wall of the case and the evaporator is fitted and fixed to the wall as in Japanese Utility Model Publication No. 54-45620.

の発生を助長する等の問題があった。However, these fixing methods generally play a large role in positioning the evaporator within the case, and are not very effective in terms of fixing the evaporator. Moreover, the above-mentioned fixing method uses the molded part of the case and the locking wall,
There are problems that the movement of air is obstructed, the heat exchange area is reduced, and the air is transformed, which increases the ventilation resistance and promotes the generation of noise.

する不具合がある。In this case, if the height of the molded portion of the case and the height of the locking wall are reduced in order to solve the above-mentioned problems, there is a problem that the evaporator rides on them during assembly, resulting in frequent assembly failures.

に断熱材を巻き付けて、組付けるようにしている。On the other hand, conventionally, a heat insulating material is adhered to the inner surface of the air conditioning case. For example, in Japanese Utility Model Publication No. 62-8165, the heat insulating material is adhered to the entire surface of the case. However, this bonding work is cumbersome, time-consuming, and expensive, so recently, a heat insulating material is bonded only to the bottom of the inner surface of the lower case, and the heat insulating material is attached to the upper peripheral surface of the evaporator that is in contact with the inner surface of the upper case. It is wrapped around and assembled.

ちぎれる心配がある。However, this assembling method has a problem that the evaporator moves after the case is assembled because the surface of the heat insulating material wound around the evaporator is smooth, and the above method has a problem in that the heat insulating material surrounds the evaporator. Since it protrudes from the surface and avoids direct contact between the case and the evaporator, when pushing the four corners of the evaporator into the molding part of the air-conditioning case or the locking wall, it takes a lot of time and effort to perform the work. Moreover, there is a concern that the insulation will be severely compressed and will be torn off in the worst case.

を特徴としている。For this reason, in the installation structure of the heat exchanger in the air conditioning case of the present invention, the heat exchanger is arranged on the inner surface of the air conditioning case via a heat insulating material and engaged with the heat exchanger. In the installation structure of the heat exchanger in the air conditioning case in which the ribs that protrude from the inner surface of the air conditioning case are provided, a plurality of guide ribs are arranged at predetermined intervals on the inner surface of the air conditioning case, and the guide ribs are provided on at least the upstream end surface of the heat exchanger. It is arranged parallel to the moving direction of air in the air-conditioning case to improve the assembling property of the heat exchanger and to increase the heat exchange area and prevent the air from transforming. I am trying. Further, the installation structure of the heat exchanger in the air conditioning case of the present invention is opposed to the heat exchanger in the installation structure of the heat exchanger in the air conditioning case in which the heat exchanger is arranged on the inner surface of the air conditioning case via the heat insulating material. A rib having a substantially triangular cross section is projectingly provided on the opposing surface of the air conditioning case, the tip of the rib is formed to have a draft of 0 °, and the tip of the rib is pressed against the heat insulating material so that the rib evenly digs into the heat insulating material. The feature is that the heat exchanger can be firmly fixed by uniformly pressing the peripheral surface of the heat exchanger.

を奏するWhen the heat exchanger is assembled, the heat insulating material enters between the guide ribs and escapes, so that the heat insulating material can be assembled without requiring arm strength. Therefore, pressure on the heat insulating material is reduced, so that the heat insulating material is not torn off and the air conditioning case and the heat exchanger do not come into direct contact with each other. By arranging the guide ribs in parallel with the moving direction of air, the ventilation resistance is reduced, and the air is guided to the entire surface of the heat exchanger to increase the heat exchange area, thereby improving the heat exchange performance. By using a rib with a substantially triangular cross-section, the tip bites strongly into the heat insulating material, firmly fixing the heat exchanger and obtaining a good sealing effect,
Moreover, a draft of 0 ° is possible at the tip. And
By setting the draft of the rib tips to 0 °, the ribs bite into the heat insulating material evenly, and the peripheral surface of the heat exchanger is evenly pressed to firmly fix the heat exchanger. A good sealing effect is achieved by eliminating the gap between the case and the heat insulating material.

い。On the other hand, the through holes 15 and 16 are closed from the inside by a heat insulating material 14, and the peripheries thereof are ribs 12, 20 and 13,
Since it is surrounded by 19 and the upper end of the evaporator 11 is in pressure contact with its peripheral edge, airtightness around the through holes 15 and 16 is maintained. Therefore, the air introduced into the air conditioning case 1 during the air conditioning operation does not leak from the through holes 15 and 16.

空調運転時にエバポレータ１１から発生する冷媒流動音
を拾うことはない。In this case, since the heat insulating material 14 is pressed relatively slowly between the upper case 4 and the evaporator 11, it does not function as a sound conduction path, and therefore is generated from the evaporator 11 during the air conditioning operation. It does not pick up the refrigerant flow noise.

れ、その冷風が空気出口３から流出する。When the air conditioning operation is started after the air conditioning case 1 has been assembled in this way, air is introduced into the air conditioning case 1 and is guided to the plurality of guide ribs 22, and the evaporator 11 is introduced from the air inlet 2 as shown by the arrow in FIG. To be cooled, and the cold air flows out from the air outlet 3.

抵抗を低減し異音の発生を防止する。At this time, since the guide ribs 22 are arranged in parallel with the moving direction of air, the ribs 22 do not have ventilation resistance and guide air to the evaporator 11. In this case, if the locking wall 21 is omitted, air is sent to the evaporator 11 behind the wall 21 and heat exchange is performed at this portion, so that the heat exchange area is substantially increased and the heat exchange performance is improved. The flow of current due to the wall 21 is eliminated, ventilation resistance is reduced, and abnormal noise is prevented.

り、良好なシール効果を得られる効果がある。As described above, the heat exchanger installation structure in the air conditioning case according to the present invention has a plurality of guide ribs arranged at a predetermined interval on the inner surface of the air conditioning case. It can be inserted into the space and escape, and can be assembled without requiring physical strength, and the assembling property can be improved. Therefore, pressure on the heat insulating material is reduced, and the heat insulating material is not torn off, and the air conditioning case and the heat exchanger do not come into direct contact with each other. In particular, this effect is to prevent the situation where the air conditioning case and the heat exchanger come into direct contact with the recent assembly method in which the heat insulating material is wrapped around the heat exchanger and the heat insulating material is not adhered to the inner surface of the upper case. , The heat insulator is extruded from the heat exchanger and assembled, and the pressure of the heat insulator is promoted, which may cause the occurrence of the above situation. However, if the present invention is applied to this, the occurrence of the above situation can be prevented. There are advantages. Further, since it is arranged at least along the upstream end surface of the heat exchanger in parallel with the moving direction of the air in the air conditioning case, the ventilation resistance is reduced, and the air is guided to the entire surface of the heat exchanger, so that the heat exchange area is reduced. There is an effect that it is possible to increase the air flow and prevent the air flow. On the other hand, according to the present invention, ribs having a substantially triangular cross section are projected on the opposing surface of the air conditioning case arranged in the heat exchanger, the tips of the ribs are formed with a draft of 0 °, and the tips of the ribs are pressed against the heat insulating material. Therefore, the ribs can bite into the heat insulating material uniformly, uniformly press the peripheral surface of the heat exchanger, and firmly fix it. Further, by setting the draft angle of the rib tip to 0 °, there is an effect that a gap between the case and the heat insulating material due to the draft angle is eliminated and a good sealing effect can be obtained.
