Abstract
Description
- The invention relates to heat exchangers; in particular to engine cooling system radiators.
- Heat exchangers, particularly those used as engine cooling system radiators, often have a generally rectangular heat exchanger matrix, an inlet header tank and an outlet header tank each at a respective one of one pair of opposite side edges of the matrix and a pair of side plates each arranged at an a respective one of the other pair of opposite side edges of the matrix. The matrix has a number of tubes extending in a parallel array between the tanks to provide a path for liquid coolant to flow from one tank to the other. Cooling fins are arranged between adjacent pairs of tubes and between each side plate and the adjacent tube such that in use air flows between adjacent pairs of tubes and between each side plate and its adjacent tube.
- A problem with the heat exchangers described above is that the tubes which are adjacent the side plates may be overcooled since it is common to provide the same size and type of fins between these components as are used between adjacent pairs of tubes. The fins situated between a side plate and an adjacent tube can conduct heat away from one tube only while the fins situated between adjacent pairs of tubes have to conduct heat away from two tubes. This overcooling can be particularly noticeable if the heat exchanger is arranged with the tubes horizontal and the header tanks vertical (a so-called cross flow radiator). Where there is a relatively low rate of flow of liquid coolant and high air flow such as is encountered in a motor vehicle during gentle open road cruising, the hotter coolant tends to rise by convection to the upper tubes. The difference in temperature between the uppermost tube (i.e., the one adjacent the uppermost side plate) and the next tube down can lead to stress cracking of the tubes or tube to header tank joint with a subsequent loss of coolant.
- According to the invention, there is provided a heat exchanger having a generally rectangular heat exchanger matrix, an inlet header tank and an outlet header tank each at a respective one of a pair of opposite side edges of the matrix and a pair of side plates each arranged at an a respective one of the other pair of opposite side edges of the matrix. The matrix has a plurality of tubes extending in a parallel array between the tanks to provide a path for liquid to flow from one tank to the other and cooling fins arranged between adjacent pairs of tubes and between each side plate and the adjacent tube such that, in use, air flows between adjacent pairs of tubes and between each side plate and the adjacent tube. The heat exchanger also has heat transfer restrictors to restrict the transfer of heat from the tube adjacent one of the side plates to the air flow between the one side plate and the tube.
- In one embodiment, the heat transfer restrictor has a restrictor plate arranged on at least one of the side plates to restrict the flow of air between the one side plate and the adjacent tube.
- In another embodiment, the restrictor plate has a blanking plate having cut out gaps or castellations. The blanking plate, in use, blocks the flow of air between the side plate and the adjacent tube over part of its length and allowing air to flow through the gaps over the remainder of its length. Alternatively, the restrictor plate has a blanking plate with perforations to restrict the flow of air between the side plate and the adjacent tube or a strip of constant width that extends the length of the side plate and over part of the gap between the side plate and the adjacent tube to leave a narrow slit for air to pass through. The restrictor plate may be attached to or form part of a cooling fan cowl.
- An advantage of the present invention is that the heat transfer rate from the plurality of tubes is more uniform so that the temperatures differences are lessened. Consequently, the stresses on the radiator are less, thereby preventing cracking failures.
- The invention will now be described by way of example and with reference to the accompanying drawings, in which:
-
FIG. 1 is a perspective view of part of a vehicle heat exchanger according to the invention; and -
FIG. 2 is a perspective view based onFIG. 1 but to a larger scale showing part of a conventional vehicle heat exchanger according to the prior art. - The
vehicle heat exchanger 11 shown inFIG. 1 is a cross flow radiator for an engine cooling system. It has a generally rectangularheat exchanger matrix 12, aninlet header tank 13 and anoutlet header tank 14, each at a respective one of one pair ofopposite side edges 15 of thematrix 12. Aside plate 16 is arranged at the upper of the other pair ofopposite side edges 17 of thematrix 12, there being acorresponding side plate 16 arranged at the opposite, lower, side edge (not shown). Thematrix 12 has a number oftubes 18 which extend in a parallel array between thetanks Cooling fins 19 are arranged between adjacent pairs of thetubes 18 and between eachside plate 16 and the adjacent tube such that in use air flows not only between adjacent pairs of tubes but also between each side plate and its adjacent tube. As is best seen in the conventional heat exchanger shown inFIG. 2 , thefins 19 are in the form of a flat strip bent into a corrugated or serpentine formation with the crests bonded to the tubes to aid conduction. As a production expedient, thefins 19 are identical throughout thematrix 12 such that the fins 19A between eachside plate 16 and itsadjacent tube 18A are the as fins 19B as those betweenadjacent tubes - In
FIG. 2 ,tube 18A is cooled by fins 19A and 19B. Fin 19B is shared betweentubes fin 19B and 18B and 18C share fin 19C. Becausetube 18A has one fin that is not shared, fin 19A, and one fin that is shared, fin, 19B, it receives preferential cooling compared totube 18B in which its two adjacent fins are shared fins. Consequentlytube 18A, which is an edge tube, runs cooler than interior tubes, such astubes 18B and 18C. The drawback of unequal heat transfer rates is that theedge tube 18A runs colder than itsadjacent tube 18B so that the different expansion rates create stresses that can result in structural failure. - In the heat exchanger shown in
FIG. 1 , arestrictor plate 21, according to an aspect of the present invention, is arranged on theupper side plate 16 to restrict the flow of air past edge fin 19A, i.e., the fin betweenside plate 16 anduppermost tube 18A.Restrictor plate 21 is shown as being attached to side plate 16 (e.g. by adhesives, riveting or by welding). However, in an alternative embodiment,restrictor plate 21 is formed as part ofside plate 16. In yet another alternative embodiment,restrictor plate 21 is part of or attached to a fan cowl of any known type, e.g. as shown in EP0108479B1. Therestrictor plate 21 is a rectangular blanking plate which blocks the flow of air which would pass through the space between theside plate 16 and theuppermost tube 18A. As shown inFIG. 1 ,restrictor 21 has cut-out gaps. - Other forms of openings can be arranged in the
restrictor plate 21, e.g. circular holes or perforations. Alternatively, there are no openings as such but instead therestrictor plate 21 is a plain rectangular strip of constant width that extends horizontally the length of theside plate 16 and vertically over part of the gap between the side plate and the adjacent tube to leave a narrow slit for air to pass through. Alternatively, the restrictor plate is arranged on the downstream (relative to the airflow) side of theside plate 16. In yet another alternative, a restrictor plate is placed on both sides, e.g. forming the sides of a channel section. Indeed, other heat transfer restrictors may be provided to restrict the transfer of heat from the tube adjacent the side plate to the air flow between the side plate and the tube. For example, thefins 19 may be reduced in number or in length to reduce their ability to transfer heat from the tube to the airflow. - Although
restrictor plate 21 and its variations and equivalents have been described in relation to the top side plate of a cross flow radiator, a flow restrictor can also be used on the lower side plate or on the side plates of a vertical flow radiator. However, the problem of thermal expansion is usually much less concern in these areas. Other heat exchangers may also benefit, e.g. air conditioning condensers.
