Problems solved by technology

However, in such a fixing structure using screws and rivets, it is necessary not only to pre-process holes for screws or rivets in the heat exchanger, but also to prepare screws and rivets separately.
As a result, the manufacturing process is complicated and the manufacturing cost is increased. Therefore, various technologies to deal with the above problems have been proposed in the past.

Embodiment Construction

[0041] Hereinafter, a heat exchanger according to an embodiment of the present invention will be described with reference to the drawings. In addition, the case where the heat exchanger is a condenser of a vehicle air conditioner is taken as an example for description.

[0042] figure 1 A perspective view showing the appearance of the condenser 1 as a heat exchanger. For example, the condenser 1 is incorporated in a refrigerant circuit constituting a refrigeration cycle of a vehicle air conditioner (not shown), and functions as a radiator for cooling the refrigerant during operation of the air conditioner.

[0043] The characteristic point of the present invention is that the mounting structure of the condenser 1 with respect to the mounting bracket used when the condenser 1 is assembled to the vehicle is improved. The basic structure that the heat exchanger should have may be a conventional general structure. Therefore, below, the structure of the condenser 1 will be brief...

Abstract

A heat exchanger is provided with: a support frame member (10) for reinforcement, the support frame member (10) being disposed at the peripheral edge of the core; and a bracket (20) for mounting, the bracket (20) having a part thereof affixed to the support frame member and serving as a mounting member for mounting to the vehicle side. The support frame member (10) is a long member having a substantially squared C-shaped transverse cross-section, and also having a groove (11) extending therein. A flange (22) is provided to one end side of the bracket (20) so as to extend from the bracket body (21) along the longitudinal direction (LD) within the groove. Sloped sections sloped in the longitudinal direction are provided on the upper surface of the flange. The support frame member is affixed by staking edges (12) thereof in such a manner that the edges (12) cover the flange (22) from above. The staked and deformed edges (12) form sloped surfaces (12a) which follow the shape of the sloped sections of the flange in the longitudinal direction.

Description

technical field [0001] The present invention relates to a heat exchanger used in a vehicle air conditioner. Background technique [0002] As a heat exchanger connected to a refrigerant circuit of a vehicle air conditioner, for example, a condenser and an evaporator are known. Since such a heat exchanger is mounted on a vehicle as a mobile body, it must be securely fixed to a structure on the vehicle side in advance. Therefore, in many cases, members such as brackets for attachment to the vehicle side are used, and fasteners such as screws and rivets are used for fixing. However, in such a fixing structure using screws and rivets, not only preprocessing for providing holes for screws or rivets in the heat exchanger is required, but also screws and rivets must be prepared separately as a matter of course. As a result, the manufacturing process is complicated and the manufacturing cost is increased. Therefore, various techniques for dealing with the above-mentioned problems h...
