Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a seal structure for a cooler unit of a car cooler.

[0002]

[Prior Art]

 The cooler unit of the car cooler is installed between and connected to the blower unit and the heater unit. An insulator is interposed between these connecting parts by a pressing method. When the car cooler is operating, the blower built into the blower unit is driven, and the air inside the vehicle or the outside air is sucked into the blower unit and energized by the blower. Next, this air enters the cooler unit and is cooled by exchanging heat with the refrigerant circulating in the evaporator in the process of passing through the evaporator contained therein. Next, this cooling air enters the heater unit and becomes heat conditioned air by exchanging heat with the engine cooling water that circulates inside the heater in the process of flowing through the heater built in this heater unit. Is blown into the passenger compartment. The cases of the cooler unit, blower unit, and heater unit are divided into multiple parts for the convenience of incorporating the equipment inside and for the convenience of manufacturing, and the wind is blocked at the connection part of each unit. The insulator installed for this purpose is also divided into multiple pieces.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional structure, since the dividing surface of the insulator, that is, the joint is flush with the dividing surface of the case and is parallel to the pressing direction, a gap is generated at the joint of the insulator. , There was a risk that air would leak from this gap.

[0004]

Means for Solving the Problems The present invention has been proposed to solve the above problems, and its gist is to provide an insulator having a joint at a connecting portion for a heater unit and / or a blower unit. In the seal structure of the cooler unit that is connected via the interposer, the seal structure of the cooler unit is characterized in that the joint of the insulator is cut obliquely with respect to the pressing direction.

[0005]

[Action]

 Since the present invention has the above-mentioned configuration, when the heater unit and / or the blower unit is connected to the cooler unit, the insulators are pressed and the joints thereof are in close contact with each other, so that air leaks from the joints of the insulators. Never.

[0006]

【Example】

 1 to 3 show an example of a seal structure of a connecting portion between a cooler unit and a blower unit. The case of the cooler unit is divided into upper and lower parts and consists of an upper case 1A and a lower case 1B. The blower unit case is also divided into upper and lower parts and consists of an upper case 2A and a lower case 2A. The insulator installed in the connection part of the cooler unit and the blower unit is divided into two pieces to be divided pieces 3A and 3B, and the division surface, that is, the joint 30, is cut diagonally to the pressing direction. ing. The divided piece 3A is arranged around the connection portion of the upper case 1A of the cooler unit, that is, around the ventilation opening 1C, and is adhered to the outer surface of the case and the support plates 4 and 5 provided upright on this. Similarly, the divided piece 3B is arranged around the ventilation opening 1D of the lower case 1B of the cooler unit and adhered to the outer surface of the case and the support plates 6 and 7 standing on this. Support plates 8 and 9 are provided upright on the outer surface of the case around the ventilation opening 2C of the upper case 2A of the blower unit. Support plates 10 and 11 are erected on the outer surface of the case around the ventilation opening 2D of the lower case 2B of the blower unit.

After the evaporator and the like are installed inside the upper case 1A and the lower case 1B of the cooler unit, they are connected to each other. After incorporating a blower etc. inside the upper case 2A and the lower case 2B of the blower unit, these are connected to each other. Then, when the blower unit is pressed toward the cooler unit and simultaneously in the directions of arrows A and B in FIG. 3, the insulators 3A and 3B are pinched between the case outer surface of the blower unit and the case outer surface of the cooler unit, and , And is clamped by the support plates 4 to 11. Since the joints 30 of the insulators 3A and 3B are cut obliquely with respect to the pressing directions A and B, when the insulators 3A and 3B are pinched by the support plates 4 to 11, the joints 30 are cut. Since they are in close contact with each other, no air leaks through this gap.

In the above embodiment, the seams are cut diagonally with respect to the pressing directions A and B, but they can also be cut diagonally with respect to the direction in which the blower unit and the cooler unit approach. Further, the present invention can of course be applied to a seal structure in the case where the insulator is divided into three or more and a seal structure for the connecting portion between the cooler unit and the heater unit.

[0009]

[Effect of the device]

 In the present invention, since the seam of the insulator is cut obliquely with respect to the pressing direction, when the heater unit and / or the blower unit is connected to the cooler unit, the insulator is pressed and the seam is in close contact with each other. It is possible to prevent air from leaking from the joint.

[Correction content]

After the evaporator and the like are installed inside the upper case 1A and the lower case 1B of the cooler unit, they are connected to each other. The upper case 2A and the lower case 2B of the blower unit are internally provided with a blower and the like, and then these are joined together. Then, when the blower unit is pushed toward the cooler unit and at the same time in the directions of arrows A and B in FIG. 3, the insulators 3A and 3B are located on the outer surface of the blower unit, the inner surface of the cooler unit, and the inner surface of the blower unit. and it is pinched and the case outer surface of Kurayuni Tsu bets and pinched by the support plate 4-11. Since the joints 30 of the insulators 3A and 3B are cut obliquely with respect to the pressing directions A and B, when the insulators 3A and 3B are pinched by the support plates 4 to 11, the joints 30 are separated. Since they are in close contact with each other, no air leaks through this gap.
