Abstract
In a cover structure for restricting adhesion of foreign materials such as an antifreezing agent to a resinous tank of a heat exchanger, a cover member is arranged such that its first end is in the proximity of a boundary between a core portion and the resinous tank of the heat exchanger and its second end is adjacent to an opening through which air is introduced. The cover member blocks the foreign materials entering from the opening and restricts. Also, the cover member directs the air having passed through the opening toward the core portion. Thus, the tank is less likely to deteriorate due to adhesion of the foreign materials. Further, efficiency of heat exchange of the core portion improves.
Description
- This application is based on Japanese Patent Application No. 2002-230353 filed on Aug. 7, 2002, the disclosure of which is incorporated herein by reference.
- The present invention relates to a cover structure that restricts adhesion of foreign materials to a resinous tank of a heat exchanger such as a vehicular radiator.
- With regard to a resinous tank of a radiator, the tank is for example made of nylon 66 (polyamide 66). As shown in FIG. 7, when a
radiator 400 having suchresinous tank 410 is used in cold regions where an antifreezing agent is spread, if the antifreezing agent is thrown up, it is likely to pass through agrill 40 and directly adhere to thetank 410 as denoted by a thick arrow B. As a result, it causes environmental stress cracks on thetank 410. - In order to restrict the environmental stress crack of the resinous tank, for example, it is proposed to blend nylon 12 (polyamide 12) and nylon 612 (polyamide 612), which have resistant to the antifreezing agent, with the nylon 66. However, such resistant materials are generally more expensive than the nylon 66. Thus, it results in an increase in cost of the radiator. Alternatively, it is proposed to employ a
cover 420 for restricting the antifreezing agent from adhering to thetank 410, as shown in FIG. 8. It also causes an increase in cost. - It is an object of the present invention to provide a cover structure capable of reducing deterioration of a resinous tank of a heat exchanger due to adhesion of foreign materials such as an antifreezing agent.
- According to the present invention, a cover structure is applied to a heat exchanger that has a resinous tank and, a core portion for performing heat exchange. The heat exchanger is arranged adjacent to an opening through which air is introduced. A cover member includes a wall having a first end and a second end opposite to each other. The cover member is disposed such that the first end is adjacent to a boundary between the core portion and the tank and the second end is adjacent to the opening so that air passing through the opening is directed toward the core portion.
- Accordingly, the wall blocks and restricts the foreign materials from adhering to the tank. Therefore, the tank is less likely to deteriorate due to the foreign materials. Further, since the air is introduced toward the core portion along the wall, efficiency of heat exchange improves. Thus, it is possible to reduce the size of the heat exchanger.
- Preferably, the cover structure is employed in a front end of a vehicle. Especially in cold regions where the antifreezing agent is spread on roads, the cover member restricts the antifreezing agent from adhering to the tank. Thus, it reduces environmental stress cracks on the resinous tank.
- Other objects, features and advantages of the present invention will become more apparent from the following detailed description made with reference to the accompanying drawings, in which like parts are designated by like reference numbers and in which:
- FIG. 1 is a cross-sectional view of a cover for explaining an arrangement of the cover on a vehicle according to the first embodiment of the present invention;

- FIG. 3 is a cross-sectional view of the cover and a frame according to-a modification of the first embodiment;
- FIG. 4 is a cross-sectional view of a cover and a tank of a heat exchanger according to the second embodiment of the present invention;
- FIG. 5 is a perspective view of the cover and the tank according to the second embodiment of the present invention;
- FIG. 6 is a cross-sectional view of the cover and the tank according to a modification of the second embodiment of the present invention;
- FIG. 7 is a schematic cross-sectional view of a front portion of a vehicle for explaining entering of an antifreezing agent of a related art; and
- FIG. 8 is a schematic cross-sectional view of a front portion of a vehicle and a cover fixed to a tank of a heat exchanger of a related art.
- Embodiments of the present invention will be described hereinafter with reference to drawings.
- In the first embodiment, a cover structure that restricts foreign materials is employed for a radiator, which is generally mounted .in a front portion of a vehicle., As shown in FIGS. 1 and 2, a cover (cover member)100 is used as the cover structure for a
radiator 200. - The
radiator 200 cools a coolant of an engine (not shown). Acore portion 220 of theradiator 200 is constructed of a stack of tubes and fins. Thecore portion 220 performs heat exchange between air and the coolant. Acore plate 221 is interposed between thecore portion 220 and aresinous tank 210. Thetank 210 is clamped with thecore plate 221. Thetank 210 is formed of nylon 66 (polyamide 66) that includes a predetermined amount of glass fiber as a reinforcing agent. - As shown in FIG. 1, the
radiator 200 is mounted on a rear side of agrill 10, which forms an opening through which a cooling air is introduced, in anengine compartment 5. Theradiator 200 is fixed to a vehicular frame (fixing member) 20 having substantially a U-shaped cross-section. Acondenser 300, which is a heat exchanger for a cooling apparatus, is provided between thegrill 10 and theradiator 200. - The
cover 100 is made of resin such as polypropylene. As shown in FIG. 2, thecover 100 is formed with a cover portion (wall) 110 in a form of plate and twofixing portions 120. Thefixing portions 120 substantially perpendicularly protrude from thecover portion 110. Fixingholes 121 are formed in substantially middle position of thefixing portions 120.Clips 130 are inserted to thefixing holes 121 and further engaged withholes 21 formed on theframe 20, so thecover 100 is fixed to theframe 20. - The
clip 130 has stoppers in the form of parasol at its top end. Also, theclip 130 is formed with slit in its central portion along its longitudinal direction. Therefore, theclip 130 is elastically deformable during the insertion and is snapped into theholes - The
cover 110 has generally a plate shape extending in a longitudinal direction of thetank 210. Thecover 100 is arranged such that thecover portion 110 extends between thegrill 10 and thecore plate 221. Specifically, afirst side 111 is arranged adjacent to thecore plate 221, which defines a boundary between thetank 210 and thecore portion 220. Asecond side 112, which is opposite to thefirst side 111, is arranged adjacent to the top end of thegrill 10. Thecover 100 is arranged such that distances between thecore plate 221 and thefirst side 111 and between thecore plate 221 and thesecond side 112 are minimized. - While the vehicle is driven on roads on which an antifreezing agent is spread for example in cold regions, if the antifreezing agent is thrown up, the antifreezing agent is likely to enter the
engine compartment 5 from thegrill 10, as denoted by a thick arrow A in FIG. 1. In this case, because thecover portion 110 blocks the antifreezing agent, it is less likely that the antifreezing agent directly adhere to theresinous tank 210. Therefore, the cover structure reduces environmental stress cracks on theresinous tank 210 due to foreign materials such as the antifreezing agent. Accordingly, it is not required to blend resistance materials with the resin of thetank 210. - Since the
cover 100 is made of polypropylene, water absorption of thecover 100 is lower than that of thetank 210 made of nylon. Therefore, thecover 100 is less likely to cause the environmental stress cracks even if the antifreezing agent adheres to thecover 100. - In addition, since the
cover portion 110 is arranged to extend from the proximity of thecore plate 221 to thegrill 10, it functions as a duct for directing the cooling air toward thecore portion 220. Thus, thecover portion 110 restricts the cooling air from passing over the tank 210 (as denoted by a dotted arrow in FIG. 8). Also, thecover portion 110 is disposed such that it does not obstruct thecore portion 220. Accordingly, the cooling air passing through thegrill 10 is effectively applied to thecore portion 220, thereby improving efficiency of heat exchange of theradiator 200. With this, it is possible to reduce the size and further cost of theradiator 200. By the cost reduction of theradiator 200, expense of thecover 100 can be offset. - The
radiator 200 generally has a second tank (not shown) through which coolant flows at its bottom. When theradiator 200 is arranged such that the tank (first tank) 210 is on the top of thecore portion 220 and the second tank is on the bottom, a temperature of the coolant flowing in thefirst tank 210 is higher than that of the coolant flowing in the second tank. Therefore, thefirst tank 210 is in an environment that easily causes environmental stress cracks; as compared to the second tank. In a case that the cover structure is applied to thetop tank 210 of the radiator, it effectively reduces damage to thetank 210. - As a modification of the first embodiment,
protrusions 122, which correspond to theclips 130, are formed in the fixingportions 120. As shown in FIG. 3, theprotrusions 122 have shapes similar to theclips 130 so that theprotrusions 122 are engaged to theholes 21 or hollows of theframe 20. Since it is not required to form theclips 130 separately, a manufacturing cost reduces. - In the second embodiment, the
cover 100 is directly connected to thetank 210. As shown in FIGS. 4 and 5, thetank 210 hasprotrusions 211, which correspond to theclips 130 of the first embodiment. Thecover 100 is fixed by engaging theprotrusions 211 in theholes 121 of the fixingportions 120. - Accordingly, it is possible to mount the
radiator 200 on the vehicle after thecover 100 is fixed to thetank 210. Also, it is possible to fix thecover 100 to theradiator 200 after theradiator 200 is mounted on the vehicle. Thus, assemblability of the cover structure improves. Further, this is suitable in a case that theframe 20 has less space for fixing thecover 100. - As a modification of the second embodiment,
protrusions 122 corresponding to theclips 130 of the first embodiment are integrally formed in thecover 100. As shown in FIG. 6, fixingholes 212 engaging with theprotrusions 122 are formed in a wall that is provided as a part of thetank 210. Thecover 100 is fixed to thetank 210 by engaging theprotrusions 122 with the fixing holes 212. - In the first embodiment and the second embodiment, the cover structure is used for the
radiator 200, which cools the engine coolant. However, the cover structure of the present invention can be used for another heat exchanger having a resinous tank, which is located on the rear side of thegrill 10, such as an inter cooling device. - It is not always necessary that the hole, which engages with the protrusion for fixing the
cover 100, is a penetrated hole. It can be a hollow or depression as long as provides an engagement with the protrusion. - The present invention should not be limited to the disclosed embodiments, but may be implemented in other ways without departing from the spirit of the invention.
