Definitions

  • the present invention relates to a heat exchanger primarily for use in a vehicle, more particularly to the internal structure of a tank of a heat exchanger, which can prevent noise which would occur when the heat medium is flowing within it at a certain velocity.
  • the heat exchanger 1 essentially comprises a pair of tanks 2, 3, a plurality of heat transfer tubes 4 interconnecting the tanks 2, 3, and a plurality of corrugated fins 5 stacked alternately with the heat transfer tubes 4.
  • the tank 2 comprises a tank member 12, a plate 13, and a pair of caps 14, 15.
  • a plurality of slots 18 each with burring are provided, in which the heat transfer tubes 4 are inserted.
  • the chamber within the tank 2 is divided into two hermetically sealed chambers by a partition plate 8 which is provided about midway along the tank 2.
  • a hole 16 is formed and is attached to an inlet pipe 6.
  • another hole 17 is formed and is attached to an outlet pipe 7.
  • the external circulation circuit for a heat medium is connected to the inlet pipe 6 and the outlet pipe 7, the external circulation circuit for a heat medium is connected.
  • the tank 3 comprises a tank member 19, a plate 13, and a pair of caps 14, 15.
  • a plate 13 In the plate 13, a plurality of slots 18 each with burring are provided, in which the heat transfer tubes 4 are inserted.
  • a plate 10' with a hole 9' is provided within the tank 3, about one quarter of the way along the tank from the cap 14, a plate 10' with a hole 9' is provided.
  • the hole 9' a flow reducing hole
  • the plate 10' as a flow reducing plate.
  • the heat medium from the external circulation circuit enters the cap 15 side chamber in the tank 2 through the inlet pipe 6. Thence the heat medium passes through the heat transfer tubes 4 that are connected to the cap 15 side chamber of tank 2, to enter the tank 3.
  • the heat medium exchanges its heat contents with the air passing transversely through the heat exchanger 1.
  • the heat medium flows upwards as seen in Fig. 1.
  • the heat medium passes through the remaining heat transfer tubes 4 to enter the cap 14 side chamber of tank 2.
  • the heat medium exchanges its heat contents with the air passing through the heat exchanger 1, at this time also.
  • the heat medium is collected within the cap 14 side chamber of the tank 2, and flows out to the external circulation circuit through the outlet pipe 7.
  • a vertical cross section of the tank 3 including the flow reducing plate 10' is shown.
  • the flows of the heat medium flowing into the heat transfer tubes 4, are indicated by arrows C in the figure.
  • the flow reducing plate 10' functions to reduce the amount of heat medium that flows into the heat transfer tubes 4 located to the cap 14 side within the tank 3. If were it not for the flow reducing plate 10', the heat medium flowing from the right side in Fig. 3 would concentrate at the cap 14 side within the tank 3 due to its inertia. In such a situation, the amounts of heat medium flowing in the heat transfer tubes 4 of cap 14 side will be greater than the ones flowing in the heat transfer tubes 4 that are relatively remote from the cap 14.
  • the flow reducing plate 10' is provided. That is, the flow reducing hole 9' in the flow reducing plate 10' restricts the excess amount of heat medium which would reach the cap 14. In this way, the amounts of heat medium flowing into all of the heat transfer tubes 4 are equalised to approximately one value, by the function of the flow reducing plate 10'.
  • the relative position of the flow reducing hole 9' and the end 4DT of the heat transfer tube 4D viewed along the direction of flow of the heat medium within the tank 3, is depicted in Fig. 4.
  • the thickness t of the plate 13 is typically about 1 mm.
  • the amount of the protrusion B of the burring 13B must be about 2t to 3t.
  • the heat transfer tube 4D is inserted to the extent that its end 4DT protrudes from the top 13C of the burring 13B by an amount S which equals to about 2 mm. The reason why the protrusion amount S is needed is to avoid the intrusion of the brazing material from the ends 4T, 4DT into the heat transfer tubes 4, 4D when brazing.
  • a part of the end 4DT of the heat transfer tube 4D can be seen through the flow reducing hole 9'.
  • a portion of the heat medium that has passed through the flow reducing hole 9' impinges and causes a noise.
  • the present invention to provide a heat exchanger which can suppress the noise heard from near the flow reducing plate when the heat medium flows at a certain velocity within the tank.
  • the other object of the present invention is to provide a heat exchanger which can resolve the above noise problem without increment in the size of the heat exchanger.
  • a heat exchanger comprising a pair of tanks; a plurality of heat transfer tubes interconnecting the pair of tanks; a plurality of fins disposed between the plurality of heat transfer tubes; a partition plate provided within one tank and separating an inlet and an outlet; and a flow reducing plate with a flow reducing hole provided partway along within the second tank for equalising the amount of heat medium flowing within the heat transfer tubes; characterised in that at least the heat transfer tubes downstream of the flow reducing plate protrude from the inner surface of the second tank by an amount (S+B), which is less than the closest spacing of the flow reducing hole from the inner surface of the second tank.
  • the flow reducing hole is formed at a position such that no part of the end of the heat transfer tube can be seen through the hole when viewed along the direction of the flow of the heat medium within the second tank.
  • the flow reducing hole may be circular, or elongate (e.g. oval or rectangular), with a longer side closest to the inner surface of the tank.
  • Fig. 1 is a perspective view of a heat exchanger to which both the conventional art and the present invention can be applied.
  • Fig. 2 is an exploded perspective view of the heat exchanger shown in Fig. 1.
  • Fig. 3 is a partial cross sectional view of the conventional art cut along the line III-III' in Fig. 1.
  • Fig. 4 is a partial cross sectional view of the conventional art cut along the line IV-IV' in Fig. 1.
  • Fig. 5 is a partial cross sectional view illustrating the principle of the present invention cut along the line III-III' in Fig. 1.
  • Fig. 6 is a partial cross sectional view of a first embodiment of the present invention cut along the line IV-IV' in Fig. 1.
  • Fig. 7 is a partial cross sectional view of a second embodiment of the present invention cut along the line IV-IV' in Fig. 1.
  • Fig. 8 is a partial cross sectional view of a third embodiment of the present invention cut along the line IV-IV' in Fig. 1.
  • the heat exchanger according to the present invention differs from the conventional heat exchanger only in the position of the flow reducing hole and its shape. So the perspective view and exploded view of the heat exchanger according to the present invention are the same as shown in Figs. 1 and 2. Because the constitutional parts are almost the same as in the conventional art, explanations of them are omitted.
  • Fig. 5 a cross sectional view of the tank 3 illustrating the principle of the present invention is depicted.
  • burring 13B To each of the slots 18 in the plate 13 are provided burring 13B, as with the conventional structure. Further, the ends 4T, 4DT of the heat transfer tubes 4, 4D protrude from the top 13C of the burring 13B by a certain amount, also as with the conventional structure.
  • the position of the flow reducing hole 9 is designed such that its bottom (as seen in Fig. 5) 9B is higher than the end 4T, 4DT of the heat transfer tubes 4, 4D when measured from the inner surface 13S of the plate 13.
  • Fig. 6 a cross sectional view of the flow reducing plate 10 portion of the first embodiment of the present invention is shown.
  • the flow reducing hole 9 is made at such a position that the ends 4DT cannot be seen through it, when viewed along the direction of the heat medium flowing within the tank 3.
  • the bottom (as seen in Fig. 6) 9B of the flow reducing hole 9 is higher than the end 4DT of the heat transfer tube 4D.
  • a cross sectional view of the flow reducing plate 10 portion of the second embodiment of the present invention is shown.
  • the elongate flow reducing hole 9L earns the necessary passage area for heat medium by being elongate, as well as being made at such a position that the ends 4DT can not be seen through it, when viewed along the direction of the heat medium flowing within the tank 3.
  • the bottom (as seen in Fig. 7) 9B' of the flow reducing hole 9L is higher than the end 4DT of the heat transfer tube 4D.
  • a cross sectional view of the flow reducing plate 10 portion of the third embodiment of the present invention is shown.
  • the rectangular flow reducing hole 9R earns the necessary passage area for heat medium by being elongate longer in the lateral direction, as well as being at such a position that the ends 4DT cannot be seen through it, when viewed along the direction of the heat medium flowing within the tank 3.
  • the bottom (as seen in Fig. 8) 9B" of the flow reducing hole 9R is higher than the end 4DT of the heat transfer tube 4D.
  • the gap between the bottom 9B of the flow reducing hole 9 and the end 4DT of the heat transfer tube 4D, or the corresponding gap in Fig. 7 or in Fig. 8, has to be greater than zero, and in practice, the gap is preferably greater than 2 mm.
  • both of the upstream side and the downstream side heat transfer tubes 4, with regard to the flow reducing plate 10, protruding into the tank 3 have the same height measured from the inner surface 13S of the tank 3, the purpose of the present invention can also be attained even if the heat transfer tubes 4, 4D that have ends 4T, 4DT lower than the bottom 9B, 9B', 9B" of the hole in the flow reducing plate 10, are confined only to the downstream side heat transfer tubes 4, 4D.
