Description

本開示は、熱交換器に関する。 The present disclosure relates to heat exchangers.

従来、下記の特許文献１に記載の熱交換器がある。特許文献１に記載の熱交換器は、積層して配置される複数のプレート部材により構成される熱交換部と、熱交換部に外付けされる筒状の気液分離部とを備えている。
熱交換部を構成するプレート部材には、冷媒が流れる冷媒流路、及び冷却水が流れる冷却水流路が形成されている。熱交換部では、プレート部材により形成される冷媒流路及び冷却水流路がプレート部材の積層方向に交互に配置されている。熱交換部では、冷媒流路を流れる冷媒と、冷却水流路を流れる冷却水との間で熱交換が行われるようになっている。熱交換部には、冷却水との熱交換により冷媒を冷却して凝縮する凝縮部と、凝縮部を通じて凝縮された液相冷媒を更に冷却する過冷却部とが設けられている。 Conventionally, there is a heat exchanger described in Patent Document 1 below. The heat exchanger described in Patent Document 1 includes a heat exchange section configured by a plurality of plate members arranged in a stack, and a tubular gas-liquid separation section externally attached to the heat exchange section. ..
In the plate member that constitutes the heat exchange section, a coolant channel through which a coolant flows and a cooling water channel through which cooling water flows are formed. In the heat exchange section, the refrigerant flow paths and the cooling water flow paths formed by the plate members are alternately arranged in the stacking direction of the plate members. In the heat exchange section, heat is exchanged between the refrigerant flowing through the refrigerant channel and the cooling water flowing through the cooling water channel. The heat exchange unit is provided with a condensing unit that cools and condenses the refrigerant by exchanging heat with the cooling water, and a supercooling unit that further cools the liquid-phase refrigerant condensed through the condensing unit.

気液分離部は、筒状の部材からなり、熱交換部において最も外側に配置される最外殻プレート部材に直接取り付けられている。気液分離部の内部空間は、最外殻プレート部材に形成された連通孔を通じて熱交換部の凝縮部及び過冷却部に連通されている。気液分離部は、凝縮部を通じて凝縮された冷媒を貯留するとともに、凝縮された冷媒に含まれる気相冷媒及び液相冷媒を分離する部分である。気液分離部において分離された液相冷媒は、熱交換部の過冷却部に導入されることにより、過冷却される。 The gas-liquid separation part is made of a tubular member and is directly attached to the outermost shell plate member arranged at the outermost side in the heat exchange part. The internal space of the gas-liquid separating section is communicated with the condensing section and the supercooling section of the heat exchange section through the communication holes formed in the outermost shell plate member. The gas-liquid separator is a part that stores the refrigerant condensed through the condenser and separates the gas-phase refrigerant and the liquid-phase refrigerant contained in the condensed refrigerant. The liquid-phase refrigerant separated in the gas-liquid separation section is supercooled by being introduced into the supercooling section of the heat exchange section.

米国特許出願公開第２０１５／０３２３２３１号明細書U.S. Patent Application Publication No. 2015/0323231

ところで、特許文献１に記載の熱交換器では、熱交換部に形成された連通孔に気液分離部を連通させる必要があるため、熱交換部の連通孔の位置に応じて、熱交換部に対する気液分離部の取付位置は概ね定まってしまう。したがって、気液分離部の配置を自由に変更することが難しいため、結果的に熱交換器の搭載性の悪化を招く等の不都合が生じている。 By the way, in the heat exchanger described in Patent Document 1, the gas-liquid separation section needs to be communicated with the communication hole formed in the heat exchange section. The mounting position of the gas-liquid separation part with respect to is almost fixed. Therefore, it is difficult to freely change the arrangement of the gas-liquid separation unit, which results in inconvenience such as deterioration of mountability of the heat exchanger.

本開示は、こうした実情に鑑みてなされたものであり、その目的は、熱交換部に対する気液分離部の配置の自由度を向上させることの可能な熱交換器を提供することにある。 The present disclosure has been made in view of the above circumstances, and an object thereof is to provide a heat exchanger capable of improving the degree of freedom in arranging the gas-liquid separation unit with respect to the heat exchange unit.

The heat exchanger includes a heat exchange section (20) composed of a plurality of plate members, a gas-liquid separation section (30) for separating a gas-phase refrigerant and a liquid-phase refrigerant, a heat exchange section, and a gas-liquid separation section. And a connecting part (40) for connecting. The outermost shell plate member (23b) arranged on the outermost side of the plurality of plate members has a discharge port (28) through which the refrigerant passing through the heat exchange section is discharged. The connecting part has a first outer surface (41) fixed to the outermost shell plate member and a second outer surface (42) fixed to the gas-liquid separating part. An internal flow path (44) is formed inside the connecting portion so as to extend from the first outer surface to the second outer surface. A communication flow path (F11) is formed between the first outer surface of the connection portion and the outermost shell plate member to connect the discharge port and the internal flow path. The refrigerant discharged from the discharge port flows into the gas-liquid separation section through the communication flow path and the internal flow path.

また、上記課題を解決する他の態様による熱交換器（１０）は、複数のプレート部材により構成される熱交換部（２０）と、気相冷媒及び液相冷媒を分離する気液分離部（３０）と、複数のプレート部材のうち、最も外側に配置される最外殻プレート部材）２３ｂ（に一体的に接合される座面プレート部材（７０）と、座面プレート部材、及び気液分離部を連結する連結部（４０）と、を備える。最外殻プレート部材には、熱交換部を通過した冷媒が排出される排出口（２８）が形成される。連結部は、座面プレート部材に固定される第１外面（４１）と、気液分離部に固定される第２外面（４２）とを有する。連結部の内部には、第１外面から第２外面に延びるように内部流路（４４）が形成される。座面プレート部材と最外殻プレート部材との間には、排出口と内部流路とを連通させる連通流路（Ｆ１１）が形成される。排出口から排出される冷媒は、連通流路、及び内部流路を通じて気液分離部に流入する。 In addition, a heat exchanger (10) according to another aspect for solving the above-mentioned problems includes a heat exchange section (20) including a plurality of plate members, and a gas-liquid separation section (for separating a gas-phase refrigerant and a liquid-phase refrigerant ( 30), a seat surface plate member (70) integrally joined to the outermost shell plate member) 23b (outermost shell plate member of the plurality of plate members), a seat surface plate member, and gas-liquid separation. The outermost shell plate member is formed with a discharge port (28) through which the refrigerant that has passed through the heat exchange unit is discharged. It has a first outer surface (41) fixed to the member and a second outer surface (42) fixed to the gas-liquid separating portion, and the inside of the connecting portion extends from the first outer surface to the second outer surface. A flow path (44) is formed, and a communication flow path (F11) is formed between the seat surface plate member and the outermost shell plate member to connect the discharge port and the internal flow path. The discharged refrigerant flows into the gas-liquid separation section through the communication channel and the internal channel.

上記の構成によれば、連通流路の形状を適宜変更することにより、熱交換部に対する気液分離部の相対的な位置を任意に変更することができる。したがって、気液分離部の配置の自由度を向上させることが可能である。
なお、上記手段、特許請求の範囲に記載の括弧内の符号は、後述する実施形態に記載の具体的手段との対応関係を示す一例である。 According to the above configuration, the relative position of the gas-liquid separating section with respect to the heat exchanging section can be arbitrarily changed by appropriately changing the shape of the communication channel.

以下、熱交換器の実施形態について図面を参照しながら説明する。説明の理解を容易にするため、各図面において同一の構成要素に対しては可能な限り同一の符号を付して、重複する説明は省略する。
＜第１実施形態＞
はじめに、図１に示される第１実施形態の熱交換器１０について説明する。この熱交換器１０は、例えば車両に搭載される冷凍サイクルにおいて冷却水と冷媒との間で熱交換を行うために用いられる。すなわち、本実施形態の熱交換器１０では、冷媒と熱交換を行う流体として冷却水が用いられている。 Hereinafter, embodiments of the heat exchanger will be described with reference to the drawings. In order to facilitate understanding of the description, the same reference numerals are given to the same constituent elements in each drawing as much as possible, and overlapping description will be omitted.
<First Embodiment>
First, the heat exchanger 10 of the first embodiment shown in FIG. 1 will be described. The heat exchanger 10 is used, for example, for exchanging heat between the cooling water and the refrigerant in a refrigeration cycle mounted on a vehicle. That is, in the heat exchanger 10 of the present embodiment, cooling water is used as the fluid that exchanges heat with the refrigerant.

図１に示されるように、本実施形態の熱交換器１０は、熱交換部２０と、気液分離部３０と、連結部４０とを備えている。熱交換器１０は、アルミニウム合金等の金属材料により形成されている。この熱交換部２０では、図１に矢印Ｌ１で示されるように冷媒が流れる。すなわち、冷媒は、まず、熱交換部２０に設けられる凝縮部２１を流れる。凝縮部２１では、冷媒と冷却水との間で熱交換が行われることにより、冷媒が冷却されて凝縮される。凝縮部２１を通じて凝縮された冷媒は連結部４０を通じて気液分離部３０に流入する。気液分離部３０では、気相冷媒と液相冷媒とが分離されて一時的に貯留される。気液分離部３０に貯留されている液相冷媒は連結部４０を通じて、熱交換部２０に設けられる過冷却部２２に流入する。過冷却部２２では、液相冷媒と冷却水との間で更に熱交換が行われることにより、冷媒が過冷却される。 As shown in FIG. 1, the heat exchanger 10 of the present embodiment includes a heat exchange section 20, a gas-liquid separation section 30, and a connecting section 40. The heat exchanger 10 is made of a metal material such as an aluminum alloy. In the heat exchange section 20, the refrigerant flows as shown by an arrow L1 in FIG. That is, the refrigerant first flows through the condenser section 21 provided in the heat exchange section 20. In the condensing part 21, heat exchange is performed between the refrigerant and the cooling water, whereby the refrigerant is cooled and condensed. The refrigerant condensed through the condensing unit 21 flows into the gas-liquid separating unit 30 through the connecting unit 40. In the gas-liquid separation unit 30, the gas-phase refrigerant and the liquid-phase refrigerant are separated and temporarily stored. The liquid-phase refrigerant stored in the gas-liquid separation unit 30 flows into the supercooling unit 22 provided in the heat exchange unit 20 through the connecting unit 40. In the supercooling unit 22, heat exchange is further performed between the liquid-phase refrigerant and the cooling water, so that the refrigerant is supercooled.

熱交換部２０は、矢印Ｘで示される方向に積層して配置される複数のプレート部材２３を備えている。以下では、矢印Ｘで示される方向を「プレート積層方向Ｘ」とも称する。本実施形態では、プレート積層方向Ｘが水平方向となっている。また、図１に矢印Ｚで示される方向、すなわちプレート積層方向Ｘに直交する方向は鉛直方向となっている。そのため、以下では、矢印Ｚで示される方向を「鉛直方向Ｚ」と称する。また、鉛直方向Ｚのうち、矢印Ｚ１で示される方向を「鉛直方向上方Ｚ１」と称し、矢印Ｚ２で示される方向を「鉛直方向下方Ｚ２」と称する。 The heat exchange section 20 includes a plurality of plate members 23 that are stacked and arranged in the direction indicated by the arrow X. Hereinafter, the direction indicated by the arrow X is also referred to as “plate stacking direction X”. In this embodiment, the plate stacking direction X is horizontal. The direction indicated by arrow Z in FIG. 1, that is, the direction orthogonal to the plate stacking direction X is the vertical direction. Therefore, hereinafter, the direction indicated by the arrow Z is referred to as "vertical direction Z". Further, in the vertical direction Z, the direction indicated by the arrow Z1 is referred to as "vertical direction upper Z1", and the direction indicated by the arrow Z2 is referred to as "vertical direction lower Z2".

各プレート部材２３は、略矩形カップ状に形成されている。各プレート部材２３は、ろう付けにより互いに接合されている。各プレート部材２３の内部空間は、冷媒の流れる冷媒流路、又は冷却水の流れる冷却水流路を構成している。
より詳細には、凝縮部２１に配置されるプレート部材２３には、図２に示される冷媒用プレート部材２４と、図３に示される冷却水用プレート部材２５とが用いられている。 Each plate member 23 is formed in a substantially rectangular cup shape. The plate members 23 are joined to each other by brazing. The internal space of each plate member 23 constitutes a coolant passage through which a coolant flows or a cooling water passage through which cooling water flows.
More specifically, the plate member 23 arranged in the condensing unit 21 includes the refrigerant plate member 24 shown in FIG. 2 and the cooling water plate member 25 shown in FIG.

The coolant communication holes 240 and 241 are communicated with each other through a coolant passage 242 formed inside the coolant plate member 24. The refrigerant communication holes 240 and 241 have a function of an inflow port for inflowing the refrigerant into the refrigerant flow channel 242 or an exhaust port for discharging the refrigerant passing through the refrigerant flow channel 242. Cooling water communication holes 243 and 244 are provided at two corners of the refrigerant plate member 24 that are diagonally opposite to each other. The cooling water communication holes 243 and 244 are not communicated with the coolant passage 242 formed inside the coolant plate member 24.

図３に示されるように、冷却水用プレート部材２５において一方の対角に位置する２つの角部には、冷媒用連通孔２５０，２５１がそれぞれ設けられている。冷媒用連通孔２５０，２５１は、冷却水用プレート部材２５の内部に形成された冷却水流路２５２に連通されていない。冷却水用プレート部材２５において他方の対角に位置する２つの角部には、冷却水用連通孔２５３，２５４がそれぞれ設けられている。冷却水用連通孔２５３，２５４は、冷却水用プレート部材２５の内部に形成された冷却水流路２５２を通じて互いに連通されている。冷却水用連通孔２５３，２５４は、冷却水流路２５２に冷却水を流入させる流入口、又は冷却水流路２５２を通過した冷却水を排出する排出口の機能を有している。本実施形態では、冷却水流路２５２が流体流路に相当する。 As shown in FIG. 3, in the cooling water plate member 25, refrigerant communication holes 250 and 251 are provided at two diagonally opposite corners. The coolant communication holes 250 and 251 are not communicated with the cooling water flow passage 252 formed inside the cooling water plate member 25. Cooling water communicating holes 253 and 254 are provided at two corners of the cooling water plate member 25 that are diagonally opposite to each other. The cooling water communication holes 253 and 254 are communicated with each other through a cooling water flow passage 252 formed inside the cooling water plate member 25. The cooling water communication holes 253 and 254 have a function of an inflow port for inflowing the cooling water into the cooling water flow passage 252 or a discharge port for discharging the cooling water passing through the cooling water flow passage 252. In the present embodiment, the cooling water channel 252 corresponds to the fluid channel.

凝縮部２１では、各冷媒用プレート部材２４の冷媒用連通孔２４０と各冷却水用プレート部材２５の冷媒用連通孔２５０とが互いに連通されている。これらの連通孔２４０，２５０は、各冷媒用プレート部材２４の冷媒流路２４２に冷媒を分配するためのタンク、又は冷媒流路２４２を通過した冷媒を集合させるためのタンクとしての機能を有している。冷媒用プレート部材２４の冷媒用連通孔２４１及び冷却水用プレート部材２５の冷媒用連通孔２５１も、互いに連通されることにより、同様のタンクとしての機能を有している。 In the condensing part 21, the refrigerant communication hole 240 of each refrigerant plate member 24 and the refrigerant communication hole 250 of each cooling water plate member 25 are communicated with each other.

次に、本実施形態の熱交換器１０の動作例について説明する。
この熱交換器１０では、図４に一点鎖線Ｌ２で示されるように冷却水が流れる。すなわち、冷却水用流入パイプ６０から冷却水用下側タンク部Ｔ２０に流入した冷却水は、凝縮部２１の各冷却水用プレート部材２５の冷却水流路２５２及び過冷却部２２の各冷却水用プレート部材２７の冷却水流路２５２に分配される。各冷却水流路２５２を流れた冷却水は、冷却水用上側タンク部Ｔ２１に集められた後、冷却水用排出パイプ６１から排出される。 Next, an operation example of the heat exchanger 10 of this embodiment will be described.
In this heat exchanger 10, cooling water flows as shown by the alternate long and short dash line L2 in FIG. That is, the cooling water flowing from the cooling water inflow pipe 60 into the cooling water lower tank portion T<b>20 is used for the cooling water flow passage 252 of the cooling water plate member 25 of the condensing portion 21 and the cooling water of the supercooling portion 22. It is distributed to the cooling water channels 252 of the plate member 27. The cooling water that has flowed through each cooling water passage 252 is collected in the cooling water upper tank portion T21 and then discharged from the cooling water discharge pipe 61.

また、この熱交換器１０では、図１に二点鎖線Ｌ１で示されるように冷媒が流れる。すなわち、冷媒用流入パイプ５０から第１冷媒用下側タンク部Ｔ１０１に流入した冷媒は、凝縮部２１の左半分に配置される各冷媒用プレート部材２４の冷媒流路２４２、第１冷媒用上側タンク部Ｔ１１１、凝縮部２１の右半分に配置される各冷媒用プレート部材２４の冷媒流路２４２を流れた後、第２冷媒用下側タンク部Ｔ１０２に集められる。この冷媒は、凝縮部２１の冷媒流路２４２を流れる際に、凝縮部２１の各冷却水用プレート部材２５の冷却水流路２５２を流れる冷却水と熱交換を行うことにより冷却されて凝縮される。凝縮された冷媒は、第２冷媒用下側タンク部Ｔ１０２及び連結部４０を通じて気液分離部３０に流入する。より詳しくは、凝縮された冷媒は、第２冷媒用下側タンク部Ｔ１０２から最外殻プレート部材２３ｂの排出口２８、連通流路Ｆ１１、及び連結部４０の第１内部流路４４を通じて気液分離部３０に流入する。気液分離部３０に流入した冷媒は、気液分離部３０の内部において気相冷媒と液相冷媒とに分離される。気液分離部３０では、液相冷媒が鉛直方向下方Ｚ２に貯留され、気相冷媒が鉛直方向上方Ｚ１に貯留される。 Further, in this heat exchanger 10, the refrigerant flows as shown by the chain double-dashed line L1 in FIG. That is, the refrigerant flowing from the refrigerant inflow pipe 50 into the first refrigerant lower tank portion T101 has the refrigerant flow passage 242 of each refrigerant plate member 24 arranged in the left half of the condensing portion 21, the first refrigerant upper portion. After flowing through the refrigerant flow path 242 of each of the refrigerant plate members 24 arranged in the right half of the tank portion T111 and the condenser portion 21, they are collected in the second refrigerant lower tank portion T102. When this refrigerant flows through the refrigerant channel 242 of the condenser 21, it is cooled and condensed by exchanging heat with the cooling water flowing through the cooling water channel 252 of each cooling water plate member 25 of the condenser 21. .. The condensed refrigerant flows into the gas-liquid separation section 30 through the second tank for lower refrigerant T102 and the connecting section 40. More specifically, the condensed refrigerant is gas-liquid from the lower second tank portion T102 for the second refrigerant through the outlet 28 of the outermost shell plate member 23b, the communication passage F11, and the first internal passage 44 of the connecting portion 40. It flows into the separation unit 30. The refrigerant flowing into the gas-liquid separation section 30 is separated into a gas-phase refrigerant and a liquid-phase refrigerant inside the gas-liquid separation section 30. In the gas-liquid separation unit 30, the liquid-phase refrigerant is stored in the vertically lower Z2, and the gas-phase refrigerant is stored in the vertically upper Z1.

気液分離部３０において鉛直方向下方Ｚ２に貯留されている液相冷媒は、連結部４０を通じて第３冷媒用下側タンク部Ｔ１０３に流入する。より詳細には、気液分離部３０に貯留されている液相冷媒は、連結部４０の第２内部流路４５、及び最外殻プレート部材２３ｂの流入口２９を通じて第３冷媒用下側タンク部Ｔ１０３に流入する。第３冷媒用下側タンク部Ｔ１０３に流入した液相冷媒は、過冷却部２２の各冷媒用プレート部材２６の冷媒流路２４２を流れた後、第２冷媒用上側タンク部Ｔ１１２に集められる。この液相冷媒は、過冷却部２２の冷媒流路２４２を流れる際に、過冷却部２２の各冷却水用プレート部材２７の冷却水流路２５２を流れる冷却水と熱交換を行うことにより、更に冷却される。このようにして過冷却された冷媒は、第２冷媒用上側タンク部Ｔ１１２から冷媒用排出パイプ５１を通じて外部に排出される。 The liquid-phase refrigerant stored vertically downward Z2 in the gas-liquid separating section 30 flows into the third refrigerant lower tank section T103 through the connecting section 40. More specifically, the liquid-phase refrigerant stored in the gas-liquid separating section 30 passes through the second internal flow path 45 of the connecting section 40 and the inflow port 29 of the outermost shell plate member 23b to the third refrigerant lower tank. It flows into the section T103. The liquid-phase refrigerant that has flowed into the third refrigerant lower tank portion T103 flows through the refrigerant flow paths 242 of the respective refrigerant plate members 26 of the supercooling portion 22, and then is collected in the second refrigerant upper tank portion T112. This liquid-phase refrigerant further exchanges heat with the cooling water flowing through the cooling water flow passage 252 of each cooling water plate member 27 of the supercooling unit 22 when flowing through the refrigerant flow passage 242 of the supercooling unit 22. To be cooled. The refrigerant thus supercooled is discharged to the outside from the second refrigerant upper tank portion T112 through the refrigerant discharge pipe 51.

以上説明した本実施形態の熱交換器１０によれば、以下の（１）及び（２）に示される作用及び効果を得ることができる。
（１）連結部４０の側面４１と最外殻プレート部材２３ｂとの間には、最外殻プレート部材２３ｂの排出口２８と連結部４０の第１内部流路４４とを連通させる連通流路Ｆ１１が形成されている。このような構成によれば、最外殻プレート部材２３ｂと連結部４０とを連結するために配管等を用いる場合と比較すると、複雑が配管の取り回しが不要となるため、熱交換器１０の構造を簡素化することができる。また、連通流路Ｆ１１の長さや形状を変更するだけで、最外殻プレート部材２３ｂの排出口２８に対する連結部４０の相対的な位置を変更することができる。結果的に、最外殻プレート部材２３ｂに対する気液分離部３０の相対的な位置を変更することが可能であるため、気液分離部３０の配置の自由度を向上させることができる。 According to the heat exchanger 10 of the present embodiment described above, the actions and effects shown in the following (1) and (2) can be obtained.
(1) Between the side surface 41 of the connecting portion 40 and the outermost shell plate member 23b, a communication passage that connects the outlet 28 of the outermost shell plate member 23b and the first internal passage 44 of the connecting portion 40. F11 is formed. According to such a configuration, compared with the case where a pipe or the like is used to connect the outermost shell plate member 23b and the connecting portion 40, the structure of the heat exchanger 10 is complicated and does not require the handling of the pipe. Can be simplified. Further, the relative position of the connecting portion 40 to the discharge port 28 of the outermost shell plate member 23b can be changed only by changing the length and shape of the communication channel F11. As a result, it is possible to change the relative position of the gas-liquid separating section 30 with respect to the outermost shell plate member 23b, so that the degree of freedom in disposing the gas-liquid separating section 30 can be improved.

（２）熱交換部２０及び気液分離部３０は一体的に組み付けられている。このような構成によれば、それらが分離されている場合と比較すると、搭載性を向上させることができる。

For example, as shown in FIG. 11, a concave groove 49 is formed on the side surface 41 of the connecting portion 40 so as to extend from the other end of the second internal flow channel 45 to the inflow port 29 of the outermost shell plate member 23b. You may.

図１３に示されるように、第２実施形態の熱交換器１０は、最外殻プレート部材２３ｂに一体的に接合される座面プレート部材７０を更に備えている。座面プレート部材７０は、他のプレート部材２３と同様に、略矩形カップ状に形成されている。座面プレート部材７０には、連結部４０の側面４１が接合されている。本実施形態の熱交換器１０では、この座面プレート部材７０と最外殻プレート部材２３ｂとの間に第１連通流路Ｆ１１及び第２連通流路Ｆ１２が形成されている点で、第１実施形態の熱交換器１０と異なる。 As shown in FIG. 13, the heat exchanger 10 of the second embodiment further includes a seat surface plate member 70 integrally joined to the outermost shell plate member 23b. The seat plate member 70 is formed in a substantially rectangular cup shape like the other plate members 23.

It is different from the heat exchanger 10 of the embodiment.

具体的には、図１３に示されるように、座面プレート部材７０は、最外殻プレート部材２３ｂに接合される内面７１と、連結部４０が接合される外面７２とを有している。図１４及び図１５に示されるように、座面プレート部材７０には、連結部４０の第１内部流路４４に対応する位置に、座面プレート部材７０の内面７１から外面７２に貫通する貫通孔７３が形成されている。また、座面プレート部材７０には、この貫通孔７３から最外殻プレート部材２３ｂの排出口２８まで延びるように凹状の溝７４が形成されている。図１５に示されるように、この溝７４の内壁面と最外殻プレート部材２３ｂの外面とによって囲まれる空間により、排出口２８と第１内部流路４４とを連通させる第１連通流路Ｆ１１が構成されている。 Specifically, as shown in FIG. 13, the seat surface plate member 70 has an inner surface 71 joined to the outermost shell plate member 23b and an outer surface 72 joined to the connecting portion 40. As shown in FIG. 14 and FIG. 15, the seating surface plate member 70 is penetrated through the seating surface plate member 70 from the inner surface 71 to the outer surface 72 at a position corresponding to the first internal flow path 44 of the connecting portion 40. A hole 73 is formed. A recessed groove 74 is formed in the seat plate member 70 so as to extend from the through hole 73 to the discharge port 28 of the outermost shell plate member 23b. As shown in FIG. 15, the first communication flow passage F11 that connects the discharge port 28 and the first internal flow passage 44 by the space surrounded by the inner wall surface of the groove 74 and the outer surface of the outermost shell plate member 23b. Is configured.

また、図１４及び図１６に示されるように、座面プレート部材７０には、連結部４０の第２内部流路４５に対応する位置に、座面プレート部材７０の内面７１から外面７２に貫通する貫通孔７５が形成されている。また、座面プレート部材７０の内面７１には、この貫通孔７５から最外殻プレート部材２３ｂの流入口２９まで延びるように凹状の溝７６が形成されている。図１６に示されるように、この溝７６の内壁面と最外殻プレート部材２３ｂの外面とによって囲まれる空間により、流入口２９と第２内部流路４５とを連通させる第２連通流路Ｆ１２が構成されている。 Further, as shown in FIGS. 14 and 16, the seat surface plate member 70 penetrates from the inner surface 71 of the seat surface plate member 70 to the outer surface 72 at a position corresponding to the second internal flow path 45 of the connecting portion 40. A through hole 75 is formed. Further, a concave groove 76 is formed on the inner surface 71 of the seat surface plate member 70 so as to extend from the through hole 75 to the inflow port 29 of the outermost shell plate member 23b. As shown in FIG. 16, the second communication flow passage F12 that connects the inflow port 29 and the second internal flow passage 45 by the space surrounded by the inner wall surface of the groove 76 and the outer surface of the outermost shell plate member 23b. Is configured.

以上説明した本実施形態の熱交換器１０によれば、上記の（２）の作用及び効果に加え、以下の（３）に示される作用及び効果を得ることができる。
（３）座面プレート部材７０と最外殻プレート部材２３ｂとの間には、最外殻プレート部材２３ｂの排出口２８と連結部４０の第１内部流路４４とを連通させる第１連通流路Ｆ１１が形成されている。また、座面プレート部材７０と最外殻プレート部材２３ｂとの間には、最外殻プレート部材２３ｂの流入口２９と連結部４０の第２内部流路４５とを連通させる第２連通流路Ｆ１２が形成されている。このような構成によれば、最外殻プレート部材２３ｂと連結部４０とを連結するために配管等を用いる場合と比較すると、複雑が配管の取り回しが不要となるため、熱交換器１０の構造を簡素化することができる。また、第１連通流路Ｆ１１及び第２連通流路Ｆ１２の長さや形状を変更するだけで、最外殻プレート部材２３ｂの排出口２８に対する連結部４０の相対的な位置を変更することができる。結果的に、最外殻プレート部材２３ｂに対する気液分離部３０の相対的な位置を変更することが可能であるため、気液分離部３０の配置の自由度を向上させることができる。 According to the heat exchanger 10 of the present embodiment described above, in addition to the action and effect of the above (2), the action and effect of the following (3) can be obtained.
(3) A first communication flow that connects the discharge port 28 of the outermost shell plate member 23b and the first internal flow path 44 of the connecting portion 40 between the seat surface plate member 70 and the outermost shell plate member 23b. The path F11 is formed. Further, between the seat surface plate member 70 and the outermost shell plate member 23b, a second communication flow passage that connects the inlet 29 of the outermost shell plate member 23b and the second internal flow passage 45 of the connecting portion 40. F12 is formed. According to such a configuration, compared with the case where a pipe or the like is used to connect the outermost shell plate member 23b and the connecting portion 40, the structure of the heat exchanger 10 is complicated and does not require the handling of the pipe. Can be simplified. Further, the relative position of the connecting portion 40 with respect to the discharge port 28 of the outermost shell plate member 23b can be changed only by changing the lengths and shapes of the first communication channel F11 and the second communication channel F12. .. As a result, it is possible to change the relative position of the gas-liquid separating section 30 with respect to the outermost shell plate member 23b, so that the degree of freedom in disposing the gas-liquid separating section 30 can be improved.
