Definitions

  • the invention relates to a heat exchanger, in particular to the heat exchanger for a motor vehicle.
  • Heat exchangers in motor vehicles are usually responsible for thermal management of the powertrain, the air conditioning system, the power steering system, and other. This includes, for example, internal combustion vehicles and electric vehicles, wherein the proper management of the heat can reflect on emissions, fuel or energy consumption, maximal driving range, etc.
  • the similar effects may be obtained, for example, by reducing the weight and the size of the vehicle components, such as the heat exchanger.
  • the size of the heat exchanger may be reduced by implementing specific architectures that provide the same or better efficiency while using the smaller amount of space.
  • the weight of the sub-components may decrease, as well as the size thereof.
  • the weight can be further decreased by reducing the amount of material used for sub- components production, for example, by slimming the walls of the particular components.
  • the heat exchangers these days are usually made of a metal components, such as aluminum assembled with a synthetic components, such as plastic.
  • the sub-components responsible for heat exchange, such as the heat exchanger core comprising tubes assembled with the headers are usually made of metal component, whereas the sub-components responsible for delivering or collecting the media, such as tanks, are usually made synthetic material.
  • the heat exchanger core expands and/or contracts depending on the temperature of media and pressure accumulated in the system. The thermal expansion of the material can make the tubes want to move with respect to the header, thus increasing a threat of leakage.
  • the heat exchanger may suffer so-called thermal shock every time the hot medium is directed into the core and said core expansion occurs it the short time. Between the subsequent operational modes the core contracts and returns to its nominal size, which can be regarded as dimensions of the heat exchanger in the standard temperature and under normal pressure. Thus, the cycles of operational and non-operational mode may a significantly impact the longevity of the heat exchanger due to both thermal, mechanical load and corrosion.
  • the common area mostly vulnerable to thermal damage and leakage is located usually in the vicinity of tube-slot connection, especially on the inlet side of the heat exchanger.
  • the support means are configured to strengthen the inner walls of the tube by the legs extending from the terminal end of the tube and finishing beyond the point where the tube goes through the slot.
  • already existing designs include, for example, a fork-shaped portion entered using force into the terminal end of the tube. The process of introducing such portions requires a lot of precision and force from e.g. the operator.
  • Another negative aspect is the amount of time required to reinforce the tubes of a single heat exchanger, as only one portion at a time may be introduced into the tube.
  • Other applications provide reinforcement of two consecutive tubes by using a single supporting means, however, it still may not be sufficient.
  • support means are disclosed in US8656988B1 , US2005263263A1 and DE202014103206U1 .
  • US 2007/144718 A1 discloses a heat exchanger according to the preamble of claim 1. It would be desired to provide a supporting means for a heat exchanger that would reinforce at least three tubes. Moreover, these supporting means should be cheap, efficient and easy to manufacture in large quantities.
  • the object of the invention is achieved by a heat exchanger as defined in claim 1.
  • the invention provides a tube reinforcement for three or more tubes.
  • the tube reinforcement may be produced in a cheap and efficient way.
  • Providing a reinforcement for at least three tubes improves the heat exchanger's efficiency and prevents malfunction, due to e.g. thermal shock.
  • the tube comprises an inner wall deployed between the two opposite walls of the tube, wherein at least one of the projecting legs is introduced into the tube in the vicinity of the inner wall so that it is in a contact with the inner wall.
  • the tube reinforcement comprises at least one opening section, the opening section comprising at least one opening configured to fluidly communicate the tank with the tube adjacent to said opening.
  • the opening comprises two shorter sides from which the projecting legs protrude, and two longer sides deployed between the projecting legs.
  • the opening section is of a size substantially equal to the inner perimeter of the open end of the tube.
  • the openings adjacent to the same tube are inclined with respect to the tube and shifted with respect to each other in the direction of the consecutive tubes.
  • the length of the projecting legs protruding from the opening section is substantially equal to the half of length of a longer side of the opening.
  • the length of the projecting legs protruding from the opening section is substantially equal to the length of the longer side of the opening.
  • the width of the projecting legs is substantially equal to half of the shorter side of the opening section.
  • the support element comprises an upper surface, a lower surface, two side surfaces, and two terminal surfaces, wherein the upper surface faces the tank, the lower surface faces the headers, the side surfaces are parallel to the protruding legs introduced into the same tube, and the terminal surfaces are parallel to the protruding legs introduced into the neighboring tubes.
  • At least two projecting legs introduced into the same tube are deployed on the opposite terminal side surfaces of the support element.
  • the support portion comprises an arched portion connecting the projecting legs with the side surfaces of the support portions.
  • the arched portions of the neighboring support portions are deployed symmetrically between the two adjacent tubes so that the fluidal communication between the tubes and the tanks is enabled.

  • the projecting legs comprise beveled ends.
  • the tube reinforcement is made of the single sheet of metal.
  • the invention relates to heat exchangers, in particular radiators used in automobiles.

  • the heat exchanger 1 is configured to convey a cooling medium, such as a coolant through its sub-components so that the temperature of the cooling medium flowing out of the heat exchanger 1 would be lower than the temperature of the cooling medium flowing into the heat exchanger 1 thanks to heat exchange with a second medium, e.g. air.
  • a cooling medium such as a coolant
  • the cooling medium is usually delivered into the heat exchanger 1 by an inlet and collected from by an outlet.
  • the inlet and the outlet are usually deployed either on the opposite sides of the heat exchanger 1, or on the same side of the heat exchanger 1.
  • the inlet and the outlet have usually circular cross-section protruding from inlet and/or outlet of the tanks 40, 50, respectively.
  • the first tank 40 is usually an elongated container made of synthetic material that is configured to distribute the cooling medium, whereas the second tank 50 is configured to collect the cooling medium from the heat exchanger 1.

  • the shape of the tanks 40, 50 presented in the Fig.1 is proven to ensure a homogenous distribution of coolant, yet other shapes of the tanks 40, 50 that will provide similar or better performance are also allowed.
  • the tanks 40, 50 may also comprise a plurality of transverse ribs deployed alternately in a direction perpendicular to the longitudinal direction of the tanks 40, 50. Ribs provide rigidity of the tanks 40, 50 at high pressures and ensure reduced deformations thereof.

  • the headers 2, 3 are usually an elongated plates made of metal material.
  • the metallic components of the heat exchanger 1 are made of light-weight metal alloy e.g. aluminum.
  • the headers 2, 3 usually have a shape similar to the shape of the openings comprised in the tanks 40, 50. In most applications, the synthetic tanks 40,50 are assembled with metal headers 2, 3 by the means of crimping one to the other, as welding is impossible.
  • the headers 2, 3 usually comprise slots for receiving a plurality of tubes 4 which protrude from the flat surface of the header 2, 3 towards the tanks 40, 50.
  • the number of slots is usually equal to the number of the tubes 4.

  • Fig. 1 presents only an exemplary location of the tube reinforcement 10 in the heat exchanger 1.
  • Fig.2 presents an assembly of the header 2, 3 comprising a plurality of the tubes 4 and the tube reinforcement 10.
  • the space between the tubes 4 may be filled by heat dispersion elements (not shown), for example fins, in order to increase the heat exchanger 1 efficiency.
  • the tube reinforcement 10 comprises in all of its forms a support element 11, which is essentially a flat portion perpendicular to the main direction of the tubes 4.
  • the support element 11 neither enters the slot of the header 2, 3, nor the open ends of the tubes 4 and it is usually deployed between the header 2, 3 and the tank 40, 50.
  • the support element 11 visible in Fig. 2 and Fig. 3 is made of a single sheet of metal and it comprises two lateral walls perpendicular to the main direction of the tubes 4 and parallel to the main direction of the header 2, 3, and two transverse walls which are essentially perpendicular to the lateral walls.
  • Phrase "essentially perpendicular" means that some leftover material forming a sloping wall comprised in the lateral wall is allowed. In majority of applications, the lateral walls are longer than the transverse walls, yet the support element 11 comprising the transverse walls longer or equal to the lateral walls is also envisaged.
  • the tube reinforcement 10 comprises also a projecting legs 12 protruding substantially perpendicularly from the support element 11.
  • the projecting legs 12 are formed from the support element 11, so that both portions are materially connected. This may be achieved, for example, by using the stamping process, wherein it may be executable to cut the material to form the projecting legs 12 in the first action, and to bend them to desired orientation with respect to the support element 11 in the second action. Alternatively, it may be feasible to laser cut the material to shape the projecting legs 12 in the first action, and to bend them to desired orientation in with respect to the support element 11 in the second action.
  • the projecting legs 12 are usually introduced into at least three consecutive tubes 4.
  • the projecting legs 12 enter the tube 4 so that they penetrate the cross- section of the header 2, 3 as presented in the Fig. 2 .

  • the length of the projecting legs 12 protruding from the opening section 30 is substantially equal to the length of the longer side of the opening 6,7. It is highly notable that the length between the terminal end of the projecting leg 12 and the surface of the support element 11 opposite thereto is greater than the length between the inner surface of the header 2,3 and the surface of the support element 11 opposite thereto.
  • the surface of the support element 11 should be regarded as the surface not occupied by the projecting legs 12. i.e. opposite to the main direction of projection of the projecting legs 12.
  • the method of deployment of the alternate projecting legs 12 may be preferred for the shifted openings 6, 7 deployment, so that the projecting legs 12 comprised in one opening section 30 would be aligned linearly with respect to the open ends of the tube 4.
  • the protruding legs 12 are shorter than in the second example, but they are thicker and less vulnerable for deformations, as the width of the projecting legs 12 is substantially equal to shorter side of the opening section 30.
  • the projecting legs 12 are longer than in the first example, but they are able to penetrate deeper into the tube 4 to increase the contact area between the projecting legs 12 and the inner side of the tube 4, as the width of the projecting legs 12 is substantially equal to half of the shorter side of the opening section 30.
  • one pair of projecting legs 12 carried out from the opening 6, 7 may be separated along the diagonal axis of the opening 6, 7 forming spiky- shaped projecting legs 12, however, this form of legs would be undesired due to complicated production process.
  • the subject of an invention may be produced also in a different way as shown in Figs 4-6 .
  • the tube reinforcement 10 can be made of at least two segments which remain materially connected with each other.
  • the single segment is substantially a single support element 11 comprising the projecting legs 12.
  • the support element 11 presented in the Figs 4-6 usually comprises four sides, wherein each side has its surface, i.e. an upper surface S1, a lower surface S2, two side surfaces S3, S3', and two terminal surfaces S4, S4'.
  • the upper side S1 faces the tank 40, 50 and the lower surface S2 faces the headers 2, 3.
  • the planes delimited by the side surfaces S3, S3' are parallel to the planes delimited by the protruding legs 12 introduced into the same tube 4, and the planes delimited by the terminal surfaces S4, S4' are parallel to the plane delimited by the protruding legs 12 introduced into the same side of the neighboring consecutive tubes 4.
  • Figs. 4-6 show the tube reinforcements 10 comprising, amongst others, the support elements 11, the projecting legs 12 protruding from the support element 11, and at least one bar 15a, 15b configured to immobilize at least two support elements 11 with respect to each other.

  • the tube reinforcements 10 comprise two through holes deployed symmetrically and penetrating the support elements 11 towards the header 2, 3.
  • the shape of the support elements 11 may be considered as essentially rectangular, although the upper surface S1 and the lower surface S2 widens in the vicinity of the projecting legs 12. This allows to increase the ratio between the spread of the projecting legs 12 of the support element 11 introduced into consecutive tubes 4 and the spread of the side surfaces S3 and S3' of the support element 11. Consequently, the support portions 11 comprise an arched portion 14 connecting the projecting legs 12 with the side surfaces S3, S3' of the support portions 11. It further allows an undisturbed fluid transfer between the tube 4 and the tanks 40, 50 by preventing the support element 11 from blocking the ends of the tube 4.

  • the projecting legs 12 protruding from the support elements 11 comprise a length, a width, and a thickness, wherein the width of the projecting leg 12 is usually greater than its thickness and the length is greater than width and thickness.
  • the thicker projecting legs 12 significantly limit unwanted bending thereof and also increase contact surface between the tube reinforcement 10 and the inner wall of the tube 4.
  • the tube reinforcement 10 usually comprises at least two projecting legs 12 introduced into the same tube 4 that are deployed on the opposite terminal side surfaces S3, S3' of the support element 11.
