Definitions

  • the invention relates to heat exchangers.
  • heat exchangers In particular, in relates to automotive heat exchangers for exchanging heat between air and a heat exchange fluid.
  • Heat exchangers can be mounted in vehicles to exchange heat between fluid used by vehicle's systems and air, especially during movement of the vehicle.
  • heat exchangers with tubes connecting two tanks are usually used.
  • the air e.g. ram air, travels between and around the tubes to exchange heat with a heat exchange fluid travelling through the tubes.
  • Heat exchanger e.g. a radiator
  • Heat exchanger can be fixed to the vehicle's body by means of attachment means located on tanks for the heat exchange fluid, which are part of the heat exchanger.
  • the object of the invention is, a heat exchanger assembly, comprising a heat exchanger connected to a first side mounting portion and a second side mounting portion, wherein the heat exchanger is connected to the first side mounting portion by means of a first connection assembly and is connected to the second side mounting portion by a second connection assembly, the first connection assembly being a releasable spheroid joint.
  • the second connection assembly is releasable.
  • the first connection assembly comprises a first spheroid joint member located on the heat exchanger, and a second spheroid joint member located on the first side mounting portion.
  • the heat exchanger comprises a first fluid tank, and the first spheroid joint member is attached to the first tank.

  • the object of the invention is a heat exchanger assembly.
  • the heat exchanger assembly comprises a heat exchanger 10 connected to a first side mounting portion 100 and connected to a second side mounting portion 200, as seen in Fig. 5 .
  • the first side mounting portion 100 and the second side mounting portion 200 can be for example parts of a vehicle heat exchange module or parts of the vehicle's body.
  • the heat exchanger 10 is connected to the first side mounting portion 100 by means of a first connection assembly 110.

  • the first spheroid joint member 111 is attached to the first tank 11.
  • the first spheroid joint member 111 may comprise a sphere element, while the second spheroid joint member 115 comprises a socket adapted for receiving and holding the sphere element 111. Due to nature of these shapes and it being a spheroid joint, the connected elements are enabled to rotate accordingly with respect to each other when subject to external forces. This may enable relative movement of the tank 11 with respect to the side mounting portions 100, 200, e.g. when the core deforms due to thermal influence. Negative effects of such deformation on the connection can thus be decreased or eliminated.
  • the second spheroid joint member 115 may comprise a bottom portion 1151 and a top portion 1152 connected to the bottom portion 1151, wherein at least one of them is at least partly shaped so as to complement the sphere element of the first spheroid joint member 111.
  • the second spheroid joint member 115 is configured to enable relative movement of the top portion 1152 with respect to the bottom portion 1151 during insertion and/or removal of the first spheroid joint member 111. This may be enabled by utilizing elastically deforming materials to connect the portions. This can enable or facilitate insertion and/or removal of the first spheroid joint member 111 to or from the second spheroid joint member 115.
  • the bottom portion 1151 and the top portion 1152 may comprise cutouts 1151c and 1152c respectively, for accommodating the sphere element of the first spheroid joint member 111.
  • the first connection assembly 100 may comprise two or more second spheroid joint members 115 adapted for releasable connection with the first spheroid joint member 111.
  • the plurality of the second joint members 115 is located on the first side mounting portion 10.
  • the sphere element can be present on the tank 11, or it can be carried out in plurality on the first side mounting portion 100, with the corresponding complementary shaped element or elements being located on the remaining component. In other words, the sphere element and the socket can have their position reversed while maintaining their function.
  • the first fluid tank 11 has a general extension axis X, and the at least two second spheroid joint members 115 are aligned along an axis Y parallel to the general extension axis X of the first heat exchange tank 11.
  • the two second spheroid joint members 115 are located on the first side mounting portion 100.
  • the first spheroid joint member 111 may be located on an arm 111b extending from the heat exchanger 10 in the direction of the second spheroid joint member 115.
  • Figs. 4a and 4b show a second example of the first connection assembly in two connection configurations.
  • the first fluid tank 11 has a general extension axis X
  • the at least two second spheroid joint members 115 are aligned along an axis Z perpendicular to the general extension axis X of the tank, i.e. parallel to the general extension direction of tubes of the core.
  • the first spheroid joint member 111 is located on an arm 112 extending from the heat exchanger 10 in the direction of the second spheroid joint member 115.
  • provision of a plurality of second spheroid joint members 115 allows to facilitate usage of multiple heat exchanger core sizes, positions or orientations with minimal change to the existing design of applied connection means.
  • the first spheroid joint member 111 may be located eccentrically with respect to the first tank 11 when measured along the extension axis X. In other words, the first spheroid joint member 111 is located closer to one of the short sides of generally rectangular outline of the tank 11. Thanks to such configuration, it is possible to switch vertical orientation of existing heat exchanger and therefore change the exposure of the core to the incoming air. This may be useful if it is desired to free one portion of the heat exchanger assembly at the expense of the other, for example when another heat exchanger needs to be introduced to the assembly. The existing heat exchanger can effectively be moved downwards or upwards without any change to the connection assembly.
  • Fig. 5 shows a heat exchanger assembly according to the invention
  • Fig. 6 presents a detailed view of a second connection assembly of the heat exchanger.
  • the heat exchanger 10 comprises a second fluid tank 12, and the second connection assembly 210 is attached to the second tank 12.
  • the second connection assembly 210 is releasable.
  • the second connection assembly 210 comprises a latching connection 211 situated on a first portion of the second tank 12, and a positioning pin 212 on a second portion of the second tank 12, remote with respect to the first portion of the second tank 12.
  • connection assembly 210 it has analogous design to the first side mounting portion 100, i.e. the heat exchanger assembly to have symmetrical connection configuration on both of its sides.
