Benefits of technology

[0007] In view of the above-described problems, it is an object of the present invention to provide an attachment structure for attaching a blower to a heat exchanger (e.g. radiator) through an attachment member (e.g. shroud) while a relative movement between the attachment member and the heat exchanger can be restricted.

Problems solved by technology

As a result, it takes longer time for attaching the blower and for classifying the attachment structure of the blower when being recycled.
Therefore, a recycling performance of the attachment structure is deteriorated.
However, in this attachment structure, a gap may be formed between the engagement protruding portion and the engagement hole portion due to a dimension difference of the engagement protruding portion, when the shroud is attached to the radiator.

Embodiment Construction

[0022] A preferred embodiment of the present invention will be described referring to FIGS. 1-6. In this preferred embodiment, an attachment structure of the present invention is typically used for attaching a blower 20 to a radiator 10 in a vehicle. FIG. 1 is a front view of the radiator 10 and the blower 20 when viewed from a downstream air side to an upstream air side. In this embodiment, the blower 20 is a drawing-type blower disposed on the downstream air side with respect to the radiator 10. The blower 20 draws air from the downstream air side of the radiator 10, so that air is blown to the radiator 10. Alternatively, the blower 20 can also be a forcing-type blower which is disposed on the upstream air side with respect to the radiator 10. The forcing-type blower blows air to push an air flow to the radiator 10.

[0023] In this embodiment, the radiator 10 is a heat exchanger for radiating heat to air. The radiator 10 is provided with at least one heat-exchanging core and header...

Abstract

A blower is attached to a heat exchanger through an attachment member. One of the heat exchanger and the attachment member has at least one engagement portion which is detachably engaged by an elastic deformation with a hole portion provided in other one of the heat exchanger and the attachment member. At least one of the heat exchanger and the attachment member is deformed before the engagement portion is engaged with the hole portion, and is deflected and reformed when the engagement portion engages with the hole portion. Accordingly, a counteractive force due to a deflection is applied to the attachment member, to be pressed to the heat exchanger. Therefore, a relative movement between the attachment member and the heat exchanger can be restricted, even if a gap is formed therebetween when the attachment member is attached to the heat exchanger.

Description

CROSS REFERENCE TO RELATED APPLICATION [0001] This application is based on Japanese Patent Application No. 2003-363476 filed on Oct. 23, 2003, the disclosure of which is incorporated herein by reference. FIELD OF THE INVENTION [0002] The present invention relates to an attachment structure for attaching a blower to a heat exchanger. The blower is provided to blow air to the heat exchanger, for example, a radiator in a vehicle. BACKGROUND OF THE INVENTION [0003] Generally, a blower is attached to a radiator of a vehicle through an attachment member such as a shroud. Protruding portions provided in the radiator are inserted into U-shape grooves provided in the shroud at lower attachment positions of the shroud, so that the shroud is attached to the radiator (for example, refer to JP-A-11-229878). The shroud is fixed to the radiator (i.e., heat exchanger) by using bolts at two upper attachment positions. [0004] The shroud is disposed to shroud a gap between the blower and the radiator,...
