Description
- The present invention relates generally to an assembly of components and affixing means such as an attachment for attaching a first component to a second component. The present invention also relates to a method of attaching a first component to a second component employing the affixing means of the present invention. More particularly, the present invention relates to attachment components for attaching at least one heater exchanger to an attachment component of elements such as a shroud or another heat exchanger for forming a heat exchanger assembly, and a method for attaching using such attachments.
- For many years, industry has been concerned with designing improved attachments for various articles and applications. Particularly in vehicle cooling systems, heat exchangers may be affixed together as a module or as a multiple heat exchanger assembly. The industry has designed attachments suitable for attaching a heat exchanger to a component such as a shroud, a wall, another heat exchanger, a front end structure of an automotive vehicle or the like to form a heat exchanger assembly, which may be employed in articles of manufacture such as automotive vehicles. Many such assemblies have, as affixing means, fasteners such as screws, metal clips or nuts mounted to adjacent heat exchangers. Such fasteners have often been composed of carbon steel subject to ‘red rust’ or corrosion, or have had to be plated or made of stainless steel to prevent or retard costly corrosion. In the case of some heat exchanger to exchanger assemblies, in order to decrease the number of affixing means, some assemblies have included lower mounting “J” shaped brackets or the like on, for example, the second heat exchanger, that have reduced, in some interests, the amount of fasteners affixing means up to about 50%. Other methods of affixing heat exchangers, for example, either integral to plastic end tanks or using plastic flexible members may be found in the prior art. In particular, affixing means wherein a flexible hook member ‘traps’ the bracket of an adjacent exchanger by being hooked over the edge of the bracket, with heat exchanger faces approximately normal to the vehicle air stream and approximately vertical to the ground have been described. U.S. Pat. No. 5,657,817, U.S. Pat. No. 6,158,500 and U.S. Pat. No. 5,996,684 describe flexible hook members of this style.
- One of the problems with heater exchange assemblies of the sort described above is that such assemblies are often, of necessity, mounted to the vehicle frame through isolates to cushion the effects of harsh differential inertia movements relative to the vehicle frame. The assemblies are subject to high frequency/low inertia vibration movements, as well as harsh low frequency/high inertia ones. Hook type members, particularly those attaching to the edge of a mating bracket or the like are, therefore, at risk of being dislodge and could potentially cause disassembly of the attached assemblies during normal driving of the vehicle.
- It is an object of the present invention to provide assemblies, and, in particular, heat exchanger assemblies, that avoid use of screw and clip or nut fasteners, to the maximum amount possible, to affix components. It is a further object of the present invention to avoid affixing means that might be dislodged more easily during normal driving, and that do not require additional parts to restrict movement. It is a further object of the invention to provide a method for attaching a first component such as a heat exchanger to a second component such as a heat exchanger employing the affixing means of the present invention.
- The present invention provides for a robust mounting that allows the assembly of multiple components, and, in particular, heat exchangers, without, necessarily, the use of fasteners. The present invention further provides for reduced cost assemblies due to decreased parts and increased life-span of affixing over technologies currently present in the industry. The present invention further provides for heat exchangers affixed to other exchangers whereby the bracket of the adjoined heat exchanger is completely ‘submerged’ or ‘captured’ by the first heat exchanger in vehicle front to back movements so as not to be subject to dislodgement or other detachment during vibration and differential harshness conditions of normal vehicle driving. The present invention further provides for assemblies made of materials that are ‘non-corrosive’ or ‘non-metallic’ thereby avoiding prior art problems such as ‘red rust’ or ‘corrosion’ at attachment or affixing points of the components. In addition, the present invention solves present problems by providing tight packaging and an easily assembled module that can withstand all normal inertial loading placed upon it under normal driving conditions.
- According to one aspect of the invention, there is disclosed an attachment for attaching a first component of an article to a second component of the article. As an example, the attachment may be employed for attaching a first heat exchanger to a component such as a shroud, a wall, another heat exchanger, a front end structure or module of an automotive vehicle or the like for assisting in forming a heat exchanger assembly. The attachment may preferably be in two parts, a first attachment component and a second attachment component. According to one embodiment, the attachment includes flange members. In preferred embodiments of the present invention, a heat exchanger assembly, comprises a first attachment component including slot tab, a flexible member, such as ‘flex’ or ‘bayonet’ member or the like. Also preferred are embodiments which have flexible members with or without a ledge and with or without an alignment element such as a ‘post’ or ‘locator post’ combination; a second attachment component, including a mating bracket with flange combination; wherein the first attachment component is approximately parallel to the second attachment component and wherein the bracket is aligned with the opening formed by the slot walls, post or locator post of the first heat exchanger component and assembled using a sliding motion. More preferred are embodiments where the first attachment component flexible member includes a ledge, more preferred, a snapping ledge.
- Also preferred are embodiments wherein the flange of the second attachment component is captured under the slot tab of the first attachment component. Also preferred are embodiments wherein the first attachment component further includes a ‘back up’ or ‘accessory’ hole for a screw as a secondary support. Even more preferred embodiments provide for a heat exchanger assembly wherein one or more of the attachment components engage another component by snapping in. Also more preferred is a heat exchanger assembly wherein two or more of the attachment components engage other components by snapping in. In even more preferred embodiments the heat exchanger assembly comprises a first attachment component including a slot wall, slot tab, locator post, stop wall, stop edge, flex finger or bayonet and a ledge combination; and a second attachment component, including a mating bracket with flange combination; wherein the first attachment component is approximately parallel to the second attachment component and wherein the bracket is aligned with the opening or open area formed by the slot walls of the first heat exchanger component, and eventually a locator post. In even more preferred embodiments, the heat exchanger assembly components are assembled using a sliding motion.
