Benefits of technology

The patent aims to provide a heat exchanger with a fixing structure that can reduce vibration transmission to external surfaces. The heat exchanger is fixed to a case using one or more fixing portions on its surface. These portions are positioned away from the four corners of the heat exchange surface, which are also prone to vibration. This results in the heat exchanger being fixed at a position that is difficult to vibrate, so that vibration from the heat exchanger to the case is minimized. This simple structure can help to suppress noise caused by vibration transmitted through the case to external surfaces.

Problems solved by technology

However, the elastic members mounted to the case of the evaporator increase the number of components producing the evaporator.
This leads to an increase in the number of processes for manufacturing the evaporator, and leads to a reduction in the productivity.

first embodiment

[0023]A first embodiment of the present disclosure will be described with reference to FIGS. 1 to 6. An evaporator 10 is a heat exchanger arranged in a refrigeration cycle not shown, in which refrigerant is compressed by a compressor to have high temperature and high pressure and is cooled by a radiator through heat radiation. Further, refrigerant is depressurized by a depressurizing device to have low temperature and low pressure, and the refrigerant is evaporated by the evaporator 10. As illustrated in FIG. 1, the evaporator 10 according to this embodiment includes a core portion 11, an upper tank unit 12, and a lower tank unit 13. The respective components are brazed to each other.

[0024]The core portion 11 is configured by alternately stacking multiple flat tubes 14 and multiple corrugated fins 15 on each other. A side plate 16 is arranged outside of the outermost corrugated fins 15 on both sides in a stacking direction thereof (X-direction in FIG. 1). A refrigerant which is an i...

second embodiment

[0056]A second embodiment of the present disclosure will be described with reference to FIGS. 7 and 8. FIG. 7 illustrates an air conditioning apparatus for a vehicle, and an evaporator 10A is illustrated as an element configuring the air conditioning apparatus. The evaporator 10A configuring the air conditioning apparatus illustrated in FIG. 7 is integrally provided with an expansion valve 40. The evaporator 10A is connected to an outflow side of the expansion valve 40 in a refrigeration cycle device, and a refrigerant depressurized by the expansion valve 40 flows into the evaporator 10A. In the present embodiment, the fixing portion 30 is disposed at six locations. The respective fixing portion 30 is configured by a protrusion portion, similarly to the first embodiment.

[0057]As illustrated in FIG. 7, the fixing portions 30 are disposed in each of an upper tank unit 12 and a lower tank unit 13 at positions apart by 0.25 L±0.05 L and positions apart by 0.75 L±0.05 L from an end of a ...

third embodiment

[0059]A third embodiment of the present disclosure will be described with reference to FIG. 9. In FIG. 9, a configuration of a fixing portion 30B is different from that in the evaporator 10 of the first embodiment. The fixing portion 30B of the evaporator 10B according to this embodiment is defined by a protrusion portion protruding outward from a lower tank unit 13 as described above. Further, the protrusion portion is covered with an elastic member, for example, an antivibration rubber.

[0060]The fixing portion 30B is configured integrally with the protrusion portion and the elastic member, thereby being capable of surely bringing the elastic member in contact with the air conditioning case. With the above configuration, the vibration transmitted from the fixing portion 30B to the air conditioning case can be further attenuated.

Abstract

A heat exchanger has a rectangular parallelepiped shape in which refrigerant flows. When sides configuring the heat exchanger having the rectangular parallelepiped shape include a first side, a second side, and a third side, a length of the third side is shortest. A surface surrounded by the first side and the second side is a heat exchange surface of the heat exchanger. A fixing structure for fixing the heat exchanger to a case includes at least one fixing portion disposed on at least one of a surface surrounded by the first side and the third side and a surface surrounded by the second side and the third side. The fixing portion is disposed at a position where a composite vibration mode of not greater than 1000 Hz is minimum.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application is based on Japanese Patent Application No. 2012-262209 filed on Nov. 30, 2012, the disclosure of which is incorporated herein by reference.TECHNICAL FIELD[0002]The present disclosure relates to a fixing structure for a heat exchanger in which refrigerant flows.BACKGROUND ART[0003]Patent literature 1 describes a cooling evaporator in an air conditioning unit for a vehicle, and the cooling evaporator is mounted in an air conditioning unit case through elastic members at four corners of the evaporator. The elastic member absorbs vibration of the evaporator. When the vibration absorbing action will be described in more detail, the evaporator is coupled with a compressor in an engine compartment of the vehicle through a refrigerant piping, and the compressor is fitted to an engine of the vehicle and driven by the engine. For that reason, the compressor vibrates integrally with the engine. The compressor per se vibrates due to ...
