Definitions

  • the present invention relates to a heat exchanger that exchanges heat between external fluid introduced from outside and heat transmitting members for heat exchange.
  • each pipe at least includes cross pipes which are pipes arranged in a direction crossing a flowing direction of the external fluid.
  • Each pipe is stacked in a direction crossing a plane defined by a longitudinal direction of the cross pipes and the flowing direction.
  • Each pipe is stacked in such a manner that the pipes adjacent in the stacking direction, as well as the cross pipes adjacent in the stacking direction, are not brought into contact with each other.
  • EP 2 278 253 A2 published after the filing date of the present application discloses a heat exchanger having a heat transmitting structure and a guide member with a protruding portion.
  • the external fluid is easy to flow between the pipes adjacent to each other in the stacking direction.
  • the external fluid may pass through between the pipes before sufficient heat exchange is achieved.
  • some part of the external fluid may pass through between the pipes without being brought into contact with the pipes. In such cases, heat exchange efficiency may be hard to increase.
  • the heat exchanger of the invention is defined in claim 1.
  • the guide member changes the direction of the external fluid passing through the intervals, the external fluid is difficult to pass by between the heat transmitting members and then easy to be brought into contact with the heat transmitting members. Consequently, heat exchange efficiency can be enhanced.
  • the guide member is arranged in at least a section in the intervals formed between the adjacent heat transmitting members.
  • the heat transmitting members may include pipes inside which internal fluid for heat exchange can flow. Heat is exchanged between the external fluid flowing outside the heat transmitting members and the internal fluid flowing inside the heat transmitting members. Also, in the present heat exchanger, the heat transmitting members are arranged to extend in a direction crossing the flowing direction of the external fluid (a direction, for example, orthogonal to the flowing direction of the external fluid on a plane including the flowing direction). The heat transmitting members may be arranged side by side in a direction crossing a plane defined by a longitudinal direction of the heat transmitting members and the flowing direction.
  • the heat exchanger of the present invention includes a housing space for housing the heat transmitting structure. The external fluid flows through the housing space.
  • the heat transmitting members are formed into a spiral shape.
  • the spiral shape can also be described as helical shape.
  • the heat transmitting members extend in a spiral manner.
  • the spiral transmitting members may include crossing members and connecting members.
  • the crossing members are arranged to extend in the direction crossing the flowing direction of the external fluid.
  • the connecting members connect upstream members which are the crossing members located upstream in the flowing direction and downstream members which are the crossing members located downstream in the flowing direction.
  • the heat transmitting members are housed in the housing space in such spiral state.
  • the heat exchanger including the heat transmitting members having the intervals therebetween as above i.e., the heat transmitting members not in contact with each other
  • the spiral heat transmitting members can be achieved by the spiral heat transmitting members.
  • the guide member is arranged in at least a section in the intervals formed between the spiral heat transmitting members.
  • the guide member is arranged in one or both of between first connecting members (more particularly, between the adjacent first connecting members) which are the connecting members located on one end sides of the crossing members and between second connecting members (more particularly, between the adjacent second connecting members) which are the connecting members located on the other end sides of the crossing members.
  • first connecting members more particularly, between the adjacent first connecting members
  • second connecting members more particularly, between the adjacent second connecting members
  • the thermal boundary layer herein indicates a layer having a predetermined thickness, which is brought into contact with a surface of the heat transmitting member.
  • the thermal boundary layer has a different temperature than a surrounding area outside the thermal boundary layer. If the thermal boundary layer exists, direct heat transmission between the external fluid and the heat transmitting member is blocked. Thus, thermal conversion efficiency is reduced.
  • the guide member is arranged in the intervals between the connecting members as in the above-described constitution, the direction of the external fluid flowing through the intervals can be changed. Separation of the thermal boundary layers generated in the connecting members can be promoted. In this manner, heat exchange efficiency between the connecting members and the external fluid upon contact between the connecting members and the external fluid can be enhanced.
  • the guide member in the above-described respective constitutions are not specifically limited as long as the direction of the external fluid flowing along a flowing direction is changed after the external fluid reaches the guide member.
  • the guide member is configured as below.
  • the guide member includes a plate-like portion interposed between the adjacent heat transmitting members, and a protruding portion protruding from a plane of the plate-like portion.
  • the protruding portion protrudes from the plane of the plate-like portion of the guide member, the direction of the external fluid flowing along the flowing direction is changed. For example, contact of the external fluid with the protruding portion can change the direction of the external fluid to a direction toward the adjacent heat transmitting members forming the interval including the plate-like portion.
  • the protruding portion of the guide member only protrudes from the plate-like portion.
  • the protruding portion is provided.
  • the protruding portion may be arranged over the maximum possible range in the plate-like portion.
  • the protruding portion may be also arranged to extend in the direction crossing the flowing direction of the external fluid.
  • the protruding portion may be arranged such that the external fluid flowing along the flowing direction of the external fluid can hit the protruding portion.
  • the external fluid flowing through the intervals between the adjacent heat transmitting members abuts on the protruding portion and is then guided toward the respective adjacent heat transmitting members forming the interval including the plate-like portion.
  • the direction of the external fluid flowing along the flowing direction is changed.
  • the protruding portion of the guide member protrudes obliquely toward one of the two adjacent heat transmitting members of the heat transmitting members forming the interval including the plate-like portion of the guide member.
  • the external fluid flowing through the intervals between the heat transmitting members is obliquely guided toward one of the two adjacent heat transmitting members of the heat transmitting members forming the interval including the plate-like portion of the guide member.
  • the direction of the external fluid flowing along the flowing direction can be changed.
  • an angle at which the external fluid abuts on the protruding portion becomes smaller than a right angle.
  • the protruding portion does not largely obstruct the downstream flow of the external fluid.
  • the protruding portion can guide the external fluid toward one of the two adjacent heat transmitting members of the heat transmitting members forming the interval including the plate-like portion of the guide member, without largely obstructing the flow of the external fluid.
  • Opportunities to bring the external fluid into contact with the heat transmitting members can be increased. In this case, heat exchange efficiency can be enhanced.
  • the protruding portion of the guide member in the above-described respective constitutions only has to protrude from the plane of the plate-like portion.
  • the protruding portion may be a member attached to the plate-like portion, a member formed by cutting and raising the plate-like portion, or a member integrally formed with the plate-like portion.
  • a heat exchanger 1 passes and discharges external fluid (not shown) introduced from outside through a housing space (space inside a casing 10) 11 which houses a heat transmitting pipe group 2 so as to exchange heat between the external fluid and internal fluid flowing inside pipes 2a to 2h (see FIG. 1 ) constituting the heat transmitting pipe group 2.
  • the heat transmitting pipe group 2 includes a first pipe set 2x and a second pipe set 2y.

  • the second pipe set 2y includes the pipes 2e, 2f, 2g and 2h.

  • FIG. 1 three upstream pipes 26a can be seen regarding the pipe 2a.
  • FIG. 2 two upstream pipes 26a are shown regarding the pipe 2a.
  • the adjacent upstream pipes 26a are positioned at regular intervals along the stacking direction d3.

  • interspaces 12 are formed which extend along a longitudinal direction of the pipes 2a to 2h.
  • a guide member 3 is provided to change the direction of the external fluid flowing along the flowing direction d1. More particularly, in the present embodiment, the guide member 3 (see FIG. 2 ) is arranged in both interspaces 12a (see FIG. 2 ) which are the interspaces 12 formed between the adjacent connecting pipes (between the connecting pipe 28a and another connecting pipe adjacent thereto) and interspaces 12b (see FIG. 2 ) which are the interspaces 12 formed between the adjacent connecting pipes (between the connecting pipe 28b and another connecting pipe adjacent thereto).
