Description

面接触型熱交換器Surface contact heat exchanger
　本発明は、面接触型熱交換器に関する。 The present invention relates to a surface contact heat exchanger.
　従来知られている面接触型熱交換器においては、図４に示す如く、底部１１ａを有するカップ状に形成されたカッププレート１１と、カッププレート１１の底部１１ａの内側に対向する平坦なトッププレート１９とによりケーシングが形成されている。
　そして、図５に示す如く、カッププレート１１の底部１１ａの内側とトッププレート１９との間には、熱媒体１５が流通する流路１４が形成され、その流路１４にコア１２が配置される。トッププレート１９の外側には伝熱面１９ａが形成されており、その伝熱面１９ａに熱交換対象物１６が配置される。
　カッププレート１１の底部１１ａの外面側は、図４に示す如く、ボス部１３ａを有するフランジプレート１３に接する。
　そして、図６に示す如く、トッププレート１９は、カッププレート１１を介してフランジプレート１３のボス部１３ａに取付けられる。
　そのフランジプレート１３は、シール材１８を介して筐体１７に取付けられる。 As shown in FIG. 4, a conventionally known surface contact heat exchanger includes a cup plate 11 formed in a cup shape having a bottom portion 11a, and a flat top plate facing the inside of the bottom portion 11a of the cup plate 11. A casing is formed by 19.
As shown in FIG. 5, a flow path 14 through which the heat medium 15 flows is formed between the inside of the bottom portion 11a of the cup plate 11 and the top plate 19, and the core 12 is disposed in the flow path 14. . A heat transfer surface 19a is formed on the outside of the top plate 19, and the heat exchange object 16 is placed on the heat transfer surface 19a.
The outer surface side of the bottom portion 11a of the cup plate 11 is in contact with the flange plate 13 having a boss portion 13a, as shown in FIG.
As shown in FIG. 6, the top plate 19 is attached to the boss portion 13a of the flange plate 13 via the cup plate 11.
The flange plate 13 is attached to the housing 17 via a sealing material 18.
　従来の面接触型熱交換器のフランジプレート１３は、カッププレート１１、トッププレート１９よりも、板厚が厚く形成されており、成形に多くの工数を必要とする。それとともに、ボス部１３ａの存在によりフランジプレート１３の形状が複雑化し、フランジプレート１３の加工費がかかる欠点があった。
　また、面接触型熱交換器の部品点数の削減、および小型化が望まれているが、従来の面接触型熱交換器の構造では、トッププレート１９を必要とし、そのプレート１９の分、高さ寸法が大きくならざるを得ない。
　そこで本発明は、面接触型熱交換器の製造費の低減、およびその熱交換器の小型化を課題とする。 The flange plate 13 of the conventional surface contact type heat exchanger is formed thicker than the cup plate 11 and the top plate 19, and requires many man-hours for molding. At the same time, the presence of the boss portion 13a complicates the shape of the flange plate 13, resulting in a disadvantage that processing costs for the flange plate 13 are increased.
Furthermore, it is desired to reduce the number of parts and downsize the surface contact heat exchanger, but the structure of the conventional surface contact heat exchanger requires a top plate 19, and the height of the plate 19 increases. The size has to be increased.
Therefore, an object of the present invention is to reduce the manufacturing cost of a surface contact type heat exchanger and to downsize the heat exchanger.
　上記課題を解決するための第１の発明は、平坦な底部１ａの外周に縁１ｃを有するカッププレート１と、
　カッププレート１の縁１ｃに外周が接続される平坦なフランジプレート３と、
　カッププレート１とフランジプレート３との間に配置されるコア２と、
　を有し、
　コア２内に熱媒体５を導く流路４が形成され、
　カッププレート１の前記底部１ａの外面に伝熱面１ｂが形成され、その伝熱面１ｂに熱交換対象物６が配置される面接触型熱交換器である。 A first invention for solving the above problems includes a cup plate 1 having an edge 1c on the outer periphery of a flat bottom portion 1a;
a flat flange plate 3 whose outer periphery is connected to the edge 1c of the cup plate 1;
a core 2 disposed between the cup plate 1 and the flange plate 3;
has
A flow path 4 for guiding a heat medium 5 is formed in the core 2,
This is a surface contact type heat exchanger in which a heat transfer surface 1b is formed on the outer surface of the bottom portion 1a of the cup plate 1, and a heat exchange object 6 is placed on the heat transfer surface 1b.
　第２の発明は、第１の発明の面接触型熱交換器において、
　熱交換対象物６が電子機器である面接触型熱交換器である。 A second invention is the surface contact heat exchanger of the first invention, comprising:
The heat exchange object 6 is a surface contact type heat exchanger in which the object 6 is an electronic device.
　第１の発明の面接触型熱交換器は、カッププレート１が平坦な底部１ａの外周に縁１ｃを有するものであり、その縁１ｃに平坦なフランジプレート３の外周が接続される。そして、カッププレート１の前記底部１ａの外面に伝熱面１ｂが形成され、その伝熱面１ｂに熱交換対象物６が配置されるものである。
　これにより、トッププレート１９が不要となり部品点数が減少するとともに、フランジプレート３の形状が簡素となりその加工費が下がるので、面接触型熱交換器の製造費を低減することができる。
　また、トッププレート１９が不要となったことにより、その厚み分、高さ寸法を抑え、面接触型熱交換器を小型化することができる。 In the surface contact heat exchanger of the first invention, the cup plate 1 has an edge 1c on the outer periphery of the flat bottom 1a, and the outer periphery of the flat flange plate 3 is connected to the edge 1c. A heat transfer surface 1b is formed on the outer surface of the bottom portion 1a of the cup plate 1, and a heat exchange object 6 is disposed on the heat transfer surface 1b.
As a result, the top plate 19 becomes unnecessary, the number of parts is reduced, and the shape of the flange plate 3 becomes simple, reducing the processing cost, so that the manufacturing cost of the surface contact type heat exchanger can be reduced.
Further, since the top plate 19 is no longer necessary, the height dimension can be reduced by its thickness, and the surface contact type heat exchanger can be downsized.
　第２の発明の面接触型熱交換器は、熱交換対象物６が電子機器であることを特徴とする。
　これにより、製造費が少なく、かつ、占有空間（高さ）の少ない面接触型熱交換器で、電子機器を冷却することが可能となる。 The surface contact type heat exchanger according to the second invention is characterized in that the heat exchange object 6 is an electronic device.
This makes it possible to cool electronic devices with a surface contact heat exchanger that is less expensive to manufacture and occupies less space (height).

　次に、図面に基づいて本発明の実施の形態につき説明する。
　本発明の面接触型熱交換器は、特に、電動車両のインバータ等の電子機器を冷却するための電子機器冷却器として好適である。
　この面接触型熱交換器は、図１に示す如く、平坦な底部１ａを有するカップ状に形成されたカッププレート１と、カッププレート１の内部に配置されるコア２と、カッププレート１の底部１ａの内側に対向する平坦なフランジプレート３と、を具備する。
　カッププレート１の底部１ａの内側とフランジプレート３との間には、熱媒体５が流通する流路４が形成され、カッププレート１の底部１ａの外面に熱交換対象物６を配置する平坦な伝熱面１ｂが形成されている。 Next, embodiments of the present invention will be described based on the drawings.
The surface contact heat exchanger of the present invention is particularly suitable as an electronic equipment cooler for cooling electronic equipment such as an inverter of an electric vehicle.
As shown in FIG. 1, this surface contact heat exchanger includes a cup plate 1 formed in a cup shape with a flat bottom 1a, a core 2 disposed inside the cup plate 1, and a bottom portion of the cup plate 1. A flat flange plate 3 facing the inside of 1a is provided.
A flow path 4 through which a heat medium 5 flows is formed between the inside of the bottom 1a of the cup plate 1 and the flange plate 3. A heat transfer surface 1b is formed.
　フランジプレート３は、カッププレート１よりも厚く形成されるが、図４、図６のボス部１３ａを廃止し、平坦に形成されているため、従来の面接触型熱交換器よりもフランジプレート３の加工費が下がる。
　フランジプレート３は、本実施例の面接触型熱交換器のケーシングの一部を形成する。
　フランジプレート３は、その縁３ｃとカッププレート１の縁１ｃとが接続された状態で、図２、図３に示す如く、シール材８を介して、筐体７に取付けられる。 Although the flange plate 3 is formed thicker than the cup plate 1, the boss portion 13a shown in FIGS. 4 and 6 is eliminated and the flange plate 3 is formed flat. processing costs will decrease.
The flange plate 3 forms a part of the casing of the surface contact type heat exchanger of this embodiment.
The flange plate 3 is attached to the housing 7 via a sealing material 8, with its edge 3c and the edge 1c of the cup plate 1 connected, as shown in FIGS. 2 and 3.
　従来の面接触型熱交換器では、図４，図６に示す如く、フランジプレート１３のボス部１３ａの位置に合わせて、カッププレート１１の縁１１ｃに接続部１１ｂを形成している。接続部１１ｂは形成面積が大きいため、従来の面接触型熱交換器のカッププレート１１の底部１１ａの面積はその分小さくなる。また、従来の面接触型熱交換器では、図４に示す如く、底部１１ａに熱媒体５の入口孔と出口孔が形成されている。
　従来のカッププレート１１の底部１１ａの形状を、そのまま図１の実施例の伝熱面１ａとして転用すると、伝熱面１ａの面積が小さくなる。 In the conventional surface contact type heat exchanger, as shown in FIGS. 4 and 6, a connecting portion 11b is formed on the edge 11c of the cup plate 11 in accordance with the position of the boss portion 13a of the flange plate 13. Since the forming area of the connecting portion 11b is large, the area of the bottom portion 11a of the cup plate 11 of the conventional surface contact type heat exchanger is correspondingly small. Further, in the conventional surface contact type heat exchanger, as shown in FIG. 4, an inlet hole and an outlet hole for the heat medium 5 are formed in the bottom portion 11a.
If the shape of the bottom portion 11a of the conventional cup plate 11 is used as it is as the heat transfer surface 1a of the embodiment shown in FIG. 1, the area of the heat transfer surface 1a will be reduced.
　図１の実施例では、図４、図６のボス部１３ａを廃止することにより、形成面積の大きい接続部１１ｂがなく、底部１ａに入口孔と出口孔を形成する必要がないため、図１に示す如く、カッププレート１の底部１ａの外面の面積を大きくとることができ、熱交換対象物６を配置する十分な伝熱面１ｂを確保することができる。
　また、カッププレート１の底部１ａの外面に、熱交換対象物６を配置する伝熱面１ｂを形成したことにより、トッププレート１９が不要になり、トッププレート１９の分、部品点数が減少するとともに、その厚みの分、高さ寸法を抑え、面接触型熱交換器を小型化することができる。 In the embodiment of FIG. 1, by eliminating the boss portion 13a of FIGS. 4 and 6, there is no connecting portion 11b with a large forming area, and there is no need to form an inlet hole and an outlet hole in the bottom portion 1a. As shown in FIG. 2, the area of the outer surface of the bottom portion 1a of the cup plate 1 can be increased, and a sufficient heat transfer surface 1b on which the heat exchange object 6 is placed can be secured.
Furthermore, by forming the heat transfer surface 1b on which the heat exchange object 6 is placed on the outer surface of the bottom 1a of the cup plate 1, the top plate 19 is no longer necessary, and the number of parts is reduced by the top plate 19. , the height dimension can be suppressed by that thickness, and the surface contact type heat exchanger can be made smaller.
　コア２は、図１、図３に示す如く、多数の孔を設けたパンチングプレートの積層体により形成することができるが、これに限らず、コルゲートフィンやオフセットフィン等のフィンにより形成することもできる。
　この実施例では、熱交換対象物６が電子機器である場合、流体５は冷却水等の冷媒とすることができる。ただし、熱交換対象物６が加温を必要とするものである場合、流体５は加温流体とすることができる。 As shown in FIGS. 1 and 3, the core 2 can be formed by a stack of punched plates having a large number of holes, but is not limited to this, and can also be formed by fins such as corrugated fins and offset fins. can.
In this embodiment, when the heat exchange object 6 is an electronic device, the fluid 5 can be a refrigerant such as cooling water. However, if the heat exchange object 6 requires heating, the fluid 5 can be a heating fluid.
　本発明は、面接触型熱交換器として広く適用可能であり、特に電動車両のインバータ冷却器として好適である。 The present invention is widely applicable as a surface contact heat exchanger, and is particularly suitable as an inverter cooler for an electric vehicle.
