Description

【0001】
【発明の属する技術分野】
本発明は自動車等の車両に搭載される空気調和装置のエバポレータ取付構造に関する。
【0002】
【従来の技術】
自動車用空気調和装置の中には、車室内への搭載レイアウトの関係でエバポレータをユニットケースの下側部内に横置きに配置したものが知られている。
【0003】
【発明が解決しようとする課題】
エバポレータは冷媒を流通させる複数個の偏平状の冷媒チューブを適宜の間隔をおいて一方向に積層状に配置して、各冷媒チューブ間には冷却フィンを接合配置して構成されている関係上、これら冷媒チューブの積層方向に寸法のバラツキが生じ易い傾向にある。
【0004】
一方、このようなエバポレータをユニットケース内に横置きに配設する場合、エバポレータをユニットケースの左右の側壁で挾持するようにして取付けられるが、このエバポレータはエンジンルーム側の冷媒配管との兼ね合いで冷媒が前後方向に流通するように配設されるため、冷媒チューブの積層方向がユニットケースの左右側壁による挾持方向と一致するようになる。
【0005】
このため、エバポレータの冷媒チューブ積層方向の寸法のバラツキによって、該エバポレータとユニットケースの左右側壁との挟着部分に緩みが生じてエバポレータのガタツキやユニットケースの左右側壁との間の気密不良を招来するおそれがある。
【0006】
そこで、本発明はユニットケース内に横置きに配設されるエバポレータに寸法のバラツキがあっても、このバラツキを吸収してエバポレータをユニットケースの左右側壁間に緊密に挾持固定することができる空気調和装置のエバポレータ取付構造を提供するものである。
【0007】
【課題を解決するための手段】
請求項1にあっては、ユニットケースをアッパケースとロアケースとに分割して構成し、周側面に弾性材を貼設した方形のエバポレータを、これらアッパケースとロアケースとのパーティングラインを跨いで両ケースの各左右側壁との間で弾性材を圧縮変形させて横置きに弾性保持する構造であって、少なくとも前記アッパケースの左右側壁の内面には、エバポレータの左右側面の弾性材に喰に込む横リブを突設したことを特徴としている。
【0008】
請求項2にあっては、請求項1に記載のアッパケースとロアケースとのパーティングラインを略水平に形成する一方、エバポレータを前記パーティングラインを跨いで前傾状態に保持し、かつ、アッパケースの左右側壁の内面に突設される横リブをエバポレータの配設角度に合わせて傾斜して形成したことを特徴としている。
【0009】
請求項3にあっては、請求項2に記載の横リブの前端部を、アッパケースの左右側壁の下縁に沿って形成したことを特徴としている。
【0010】
請求項4にあっては、請求項1〜3に記載の横リブを上下方向に複数条設けたことを特徴としている。
【0011】
【発明の効果】
請求項1によれば、エバポレータがユニットケースの左右側壁との間で該エバポレータ周側面の弾性材を圧縮変形させて弾性保持されることと併せて、ユニットケースのアッパケースの左右側壁の内面に突設した横リブが前記弾性材に喰い込んで、弾性材が横リブとエバポレータ側面との間で圧着されることによって、エバポレータの左右方向の寸法のバラツキを吸収して該エバポレータをユニットケースの左右側壁間に緊密に挾持固定することができる。
【0012】
エバポレータはアッパケースとロアケースとのパーティングラインを跨いで横置きに弾性保持してあるから、整備時にエバポレータをユニットケースから取り外す場合、ロアケースをアッパケースから離脱するとアッパケースの下方に作業空間が確保されるため、エバポレータを容易に取り外すことができる。
【0013】
また、このロアケースの離脱時にはアッパケースの左右側壁内面の横リブがエバポレータの左右側面の弾性材に食い込んで係止しているため、エバポレータが自重でずれ下がることがなく、従って、ロアケースおよびエバポレータの取り外し作業を容易に行うことができる。
【0014】
請求項2によれば、請求項1の効果に加えて、アッパケースとロアケースとのパーティングラインを略水平に形成してあるため、ロアケースの取り外しの際には該ロアケースを車室後方へ略水平にスライドさせて取り外すことができ、狭隘な場所でのロアケースの取り外しをより一層容易に行うことができる。
【0015】
また、エバポレータは前記パーティングラインを跨いで前傾状態に弾性保持してあるため、ロアケースを取り外すとエバポレータの前端部がアッパケース下方の作業空間に突出して露出するようになるから、エバポレータの取り外しをより一層容易に行うことができる。
【0016】
しかも、このようにエバポレータの前傾配置に合わせて、アッパケースの左右側壁内面の横リブも前傾状態に形成してあるため、横リブの弾性材との係合長さを十分に確保できてエバポレータの自重によるずれ下がりを規制することができる。
【0017】
請求項3によれば、請求項2の効果に加えて、横リブの前端部をアッパケースの左右側壁の下縁に沿って形成してあるので、該アッパケースの左右側壁の下縁の剛性を高められ、ロアケースの取り外しの際にアッパケースの左右側壁下縁の外側への撓み変形を抑えてエバポレータの自重によるずれ下がりを確実に規制することができる。
【0018】
請求項4によれば、請求項1〜3の効果に加えて、横リブをアッパケースの左右側壁の内面に上下方向に複数条設けてあるため、これら左右側壁の剛性を高められて横リブと弾性材との食い込み係止を確実に行えて、エバポレータの挾持固定をより確実に行うことができる。
【0019】
【発明の実施の形態】
以下、本発明の一実施形態を図面と共に詳述する。
【0020】
図5は熱交換器ユニットを示し、熱交換器ユニット1はユニットケース2内にエバポレータ3と、その上側にヒータコア4とをそれぞれ横置きにして上下方向に多段に配置してある。
【0021】
エバポレータ3とヒータコア4との配設部分は上下に隔成してあって、図外のブロワユニットからユニットケース2の一側壁に設けたブロワ接続口6に送風されてくる空気を、図1の矢印で示すようにエバポレータ3の上側から下側に向かって流通させて冷却し、この冷却された空気をユニットケース2の後側壁に沿って形成した空気通路5に上向きに流通させるようにしてある。
【0022】
この空気通路5を上向きに流通する空気はヒータコア4の下側にバイパスして該ヒータコア4の下側から上側に向けて流通し得るようになっていて、エバポレータ3および又はヒータコア4によって温度調節された空気は、ユニットケース2の上壁に設けたベント吹出口7又はデフロスタ吹出口8、あるいはユニットケース2の両側壁の上部に設けたフット吹出口9から図外の各種ダクトへ供給されるようになっている。
【0023】
前記ヒータコア4への空気のバイパス流通、および各種吹出口7,8,9からの空気の吹出しは、図外の各種ドアの配風制御によって行われる。
【0024】
エバポレータ3は図4に示すように方形に形成されていて、冷媒を流通させる複数個の偏平状の冷媒チューブ11を適宜の間隔をおいて一方向に積層状に配置して、各冷媒チューブ11間に図外の冷却フィンを接合配置してあると共に、各冷媒チューブ11と直交方向となる一側部に冷媒の給排を行う冷媒タンク12と膨脹弁13とを付設した公知のラミネート式片タンクタイプのものが用いられている。
【0025】
ユニットケース2は図1〜3にも示すように、略水平なパーティングラインを境にしてアッパケース2Aとロアケース2Bとに分割して構成してあり、エバポレータ3はこれらアッパケース2Aとロアケース2Bとのパーティングラインを跨ぐように若干前傾した状態でユニットケース2内に横置きに配置してある。
【0026】
このようにエバポレータ3をユニットケース2内に前傾状態に定置するために、アッパケース2Aおよびロアケース2Bの左右両側壁の内面に、エバポレータ3の左右両側面の上下縁部に係合する前方斜め下方に傾斜した段部14,15を形成してあると共に、アッパケース2Aには段部14の前後端部に連なってエバポレータ3の前後側面の上縁に係合する段部16,17を、およびロアケース2Bには段部15の前端部に連なってエバポレータ3の前側面の下縁に係合する段部18を形成してある。
【0027】
エバポレータ3は冷媒タンク12を付設した側面を前方に向けて、アッパケース2A側の段部14,16,17と、ロアケース2B側の段部15,18とで上下方向および前後方向に位置決めして定置して、膨脹弁13がユニットケース2の前側壁に設けた開口10に臨むように横置きに配置してある。
【0028】
このエバポレータ3の冷媒タンク12を付設した前側面を除く左右両側面と後側面とに亘る周側面にはシート状の弾性材20を貼設してあり、この弾性材21をエバポレータ3の左右側面とアッパケース2Aおよびロアケース2Bの各左右側壁との間で圧縮変形させて弾性的に挾持固定すると共に、エバポレータ3の上下周縁部に張り出した弾性材20の縁部をこれらアッパケース2A,ロアケース2Bの前記各段部14,15,17に弾接させて、該弾性材20を介してエバポレータ3をユニットケース2の周側壁に防振支持してある。
【0029】
ここで、前記アッパケース2Aの左右側壁の内面には、前記エバポレータ3の左右側面の弾性材20に喰い込む例えば3角形断面の横リブ19を突設してある。
【0030】
横リブ19は例えば上下方向に適宜の間隔をおいて2条突設してあり、これら横リブ19は何れもエバポレータ3の前傾配設角度に合わせて前傾して傾斜成形してあり、下側の横リブ19の前端部はアッパケース2Aの左右側壁の下縁に沿って形成してある。
【0031】
この実施形態ではアッパケース2Aの左右側壁の後側部内面に、エバポレータ3を後方へスライド移動した際にエバポレータ3の後側部を保持する前傾した上下のガイドレール21,22を設けてある一方、ロアケース2Bの左右側壁の前側部内面に、上縁から段部15に向かう縦リブ23を前後方向に複数条設けて、エバポレータ3およびロアケース2Bの再組付け時には予め上下ガイドレール21,22に保持させたエバポレータ3にロアケース2Bを嵌合して、該ロアケース2Bを前方へ略水平に前方へスライド移動することにより、縦リブ23がエバポレータ3の左右側面の弾性材20に喰い込み係合して、該エバポレータ3も一緒に前方へスライド移動させて再組付けを容易に行えるようにしてある。
【0032】
エバポレータ3の前側面の上縁にはアッパケース2Aの前側の段部16の下面に密接するシール部材24を貼設して、エバポレータ3の上面側からくる空気を確実に熱交換用フィン部分に送るようにシールしている。
【0033】
また、冷媒タンク11の下部両側には、ロアケース2Bの前側部の段部18の立上がり面18aに弾接するクッション材25を貼設してある。
【0034】
ロアケース2Bの底部は、エバポレータ3の表面に発生して滴下する凝縮水を集合させてケース外にドレーンし易いように傾斜成形してある。
【0035】
以上の実施形態の構造によれば、エバポレータ3はその冷媒チューブ11の積層方向が左右方向となっていることから、特に左右方向の寸法にバラツキが生じ易い傾向にあるが、このエバポレータ3はユニットケース2の左右側壁、つまり、アッパケース2Aおよびロアケース2Bの各左右側壁との間で該エバポレータ3の左右側面の弾性材20を圧縮変形させて弾性保持してあり、しかも、アッパケース2Aの左右側壁の内面に突設した横リブ19が前記弾性材20に喰い込んで、弾性材20が横リブ19とエバポレータ3の側面との間で圧着されることによって、該エバポレータ3の左右方向の寸法のバラツキを吸収してエバポレータ3をユニットケース2の左右側壁間に緊密に挾持固定することができる。
【0036】
従って、エバポレータ3がユニットケース2内で左右方向にガタツキを生じたり、エバポレータ3とユニットケース2の左右側壁との間の気密不良を生じることもなく、品質感および信頼性を一段と高めることができる。
【0037】
特に、本実施形態ではロアケース2Bの左右側壁の内面に突設した縦リブ23もこのエバポレータ3の左右側面の弾性材20に喰い込むようになるから、エバポレータ3の緊密な挾持固定を有利に行うことができる。
【0038】
また、エバポレータ3はアッパケース2Aとロアケース2Bとのパーティングラインを跨いで横置きに弾性保持してあるから、整備時にエバポレータ3をユニットケース2から取り外す場合、ロアケース2Bをアッパケース2Aから離脱するとアッパケース2Aの下方に作業空間が確保されるため、エバポレータ3を容易に取り外すことができる。
【0039】
このロアケース2Bの離脱時にはアッパケース2Aの左右側壁内面の横リブ19がエバポレータ3の左右側面の弾性材20に喰い込んで係止しているため、エバポレータ3が自重でずれ下がることがなく、従って、ロアケース2Bおよびエバポレータ3の取り外し作業を容易に行うことができる。
【0040】
とりわけ、前記アッパケース2Aとロアケース2Bとのパーティングラインを略水平に形成してあって、エバポレータ3はこのパーティングラインを跨いで前傾状態に横置きに配置してあるため、ロアケース2Bは車室後方へ略水平にスライドさせて取り外すことができ、狭隘な場所でのロアケース2Bの取り外し作業をより一層容易に行えると共に、該ロアケース2Bを取り外すとエバポレータ3の前端部がアッパケース2Aの下方の作業空間に突出して露出するようになるから、該エバポレータ3の取り外しも容易に行えて整備性をより一層向上することができる。
【0041】
また、アッパケース2Aの左右側壁内面の横リブ19はエバポレータ3の前傾配置に合わせて前傾させて上下方向に複数条設けてあるから、該横リブ19の弾性材20との係合長さを十分に確保できて、ロアケース2Bの取り外し時におけるエバポレータ3の自重によるずれ下がりを規制することができる。
【0042】
しかも、このように横リブ19を上下方向に複数条設けてあるため、アッパケース2Aの左右側壁の剛性を高められると共に、前端がアッパケース2Aの左右側壁下縁に接する横リブ19は、該前端部をこれら左右側壁の下縁に沿って形成してあるので該左右側壁の下縁の剛性を高められて外側への撓み変形を抑えることができ、この結果、横リブ19と弾性材20との喰い込みをしっかりと確保してエバポレータ3の挾持固定を確実に行えると共に、ロアケース2Bの取り外し時におけるエバポレータ3の自重下がりを確実に規制することができる。

BACKGROUND OF THE INVENTION
The present invention relates to an evaporator mounting structure for an air conditioner mounted on a vehicle such as an automobile.
[0002]
[Prior art]
Among air conditioning apparatuses for automobiles, there is known an apparatus in which an evaporator is disposed horizontally in a lower side portion of a unit case because of a mounting layout in a vehicle interior.
[0003]
[Problems to be solved by the invention]
In the evaporator, a plurality of flat refrigerant tubes for circulating the refrigerant are arranged in a laminated manner in one direction at appropriate intervals, and cooling fins are joined and arranged between the refrigerant tubes. The dimensional variation tends to occur easily in the stacking direction of these refrigerant tubes.
[0004]
On the other hand, when such an evaporator is installed horizontally in the unit case, the evaporator is mounted so as to be held by the left and right side walls of the unit case. This evaporator is in balance with the refrigerant piping on the engine room side. Since the refrigerant is arranged so as to flow in the front-rear direction, the stacking direction of the refrigerant tubes coincides with the holding direction by the left and right side walls of the unit case.
[0005]
For this reason, due to variations in the dimensions of the evaporator in the stacking direction of the refrigerant tubes, looseness occurs in the sandwiched portion between the evaporator and the left and right side walls of the unit case, leading to looseness between the evaporator and the left and right side walls of the unit case. There is a risk.
[0006]
Accordingly, the present invention is an air that can absorb and hold the evaporator tightly between the left and right side walls of the unit case even if the evaporator disposed horizontally in the unit case has a dimensional variation. An evaporator mounting structure for a harmony device is provided.
[0007]
[Means for Solving the Problems]
In claim 1, the unit case is divided into an upper case and a lower case, and a rectangular evaporator having an elastic material pasted on the peripheral side surface is straddled across the parting line between the upper case and the lower case. The elastic material is compressed and deformed between the left and right side walls of both cases and elastically held horizontally. At least the inner surfaces of the left and right side walls of the upper case are eaten by the elastic materials on the left and right side surfaces of the evaporator. It is characterized by protruding side ribs.
[0008]
According to claim 2, the parting line between the upper case and the lower case according to claim 1 is formed substantially horizontally, while the evaporator is held in a forward inclined state across the parting line, and the upper The lateral ribs protruding from the inner surfaces of the left and right side walls of the case are formed so as to be inclined in accordance with the arrangement angle of the evaporator.
[0009]
According to a third aspect, the front end portion of the lateral rib according to the second aspect is formed along the lower edges of the left and right side walls of the upper case.
[0010]
In Claim 4, the horizontal rib of Claims 1-3 was provided with two or more strips in the up-down direction.
[0011]
【The invention's effect】
According to the first aspect, the evaporator is elastically held by compressing and deforming the elastic material on the peripheral side surface of the evaporator between the left and right side walls of the unit case, and on the inner surfaces of the left and right side walls of the upper case of the unit case. The projecting lateral rib bites into the elastic material, and the elastic material is pressure-bonded between the lateral rib and the side surface of the evaporator, so that the variation in the horizontal dimension of the evaporator is absorbed and the evaporator is attached to the unit case. It can be tightly clamped between the left and right side walls.
[0012]
Since the evaporator is elastically held horizontally across the parting line between the upper case and the lower case, when removing the evaporator from the unit case during maintenance, a work space is secured below the upper case when the lower case is removed from the upper case. Therefore, the evaporator can be easily removed.
[0013]
In addition, when the lower case is detached, the horizontal ribs on the inner surfaces of the left and right side walls of the upper case bite into the elastic material on the left and right side surfaces of the evaporator, so that the evaporator does not slip down due to its own weight. Removal work can be performed easily.
[0014]
According to the second aspect, in addition to the effect of the first aspect, since the parting line between the upper case and the lower case is formed substantially horizontally, when the lower case is removed, the lower case is substantially rearward in the passenger compartment. It can be slid horizontally to be removed, and the lower case can be removed more easily in a narrow place.
[0015]
In addition, since the evaporator is elastically held in a forward inclined state across the parting line, the front end of the evaporator protrudes and is exposed in the work space below the upper case when the lower case is removed. Can be performed more easily.
[0016]
In addition, since the horizontal ribs on the inner surfaces of the left and right side walls of the upper case are also formed in a forward tilted state in accordance with the forward tilting arrangement of the evaporator as described above, it is possible to sufficiently secure the engagement length of the horizontal ribs with the elastic material. Therefore, it is possible to regulate the slippage due to the weight of the evaporator.
[0017]
According to the third aspect, in addition to the effect of the second aspect, the front end portion of the lateral rib is formed along the lower edges of the left and right side walls of the upper case. When the lower case is removed, it is possible to suppress bending deformation to the outside of the lower left and right side walls of the upper case, and to reliably regulate the slippage due to the weight of the evaporator.
[0018]
According to the fourth aspect, in addition to the effects of the first to third aspects, since a plurality of horizontal ribs are provided in the vertical direction on the inner surfaces of the left and right side walls of the upper case, the rigidity of the left and right side walls can be enhanced. And the elastic material can be bite and locked reliably, and the evaporator can be held and fixed more reliably.
[0019]

A seal member 24 is attached to the upper edge of the front side surface of the evaporator 3 so as to be in close contact with the lower surface of the step 16 on the front side of the upper case 2A, and the air coming from the upper surface side of the evaporator 3 is reliably supplied to the heat exchange fin portion. Sealed to send.
[0033]
In addition, cushion materials 25 elastically contacting the rising surfaces 18a of the step portions 18 on the front side portion of the lower case 2B are attached to both sides of the lower portion of the refrigerant tank 11.
[0034]
The bottom portion of the lower case 2B is formed so as to be inclined so that condensed water generated and dripped on the surface of the evaporator 3 can be collected and easily drained out of the case.
[0035]
According to the structure of the above embodiment, since the stacking direction of the refrigerant tubes 11 is the left-right direction, the evaporator 3 tends to vary particularly in the left-right direction. The elastic members 20 on the left and right side surfaces of the evaporator 3 are compressed and deformed between the left and right side walls of the case 2, that is, the left and right side walls of the upper case 2A and the lower case 2B, and are elastically held. The lateral rib 19 projecting from the inner surface of the side wall bites into the elastic material 20, and the elastic material 20 is pressure-bonded between the lateral rib 19 and the side surface of the evaporator 3. Thus, the evaporator 3 can be tightly held and fixed between the left and right side walls of the unit case 2.
[0036]
Accordingly, the quality and reliability of the evaporator 3 can be further improved without causing the evaporator 3 to rattle in the left-right direction within the unit case 2 or causing an airtight defect between the evaporator 3 and the left and right side walls of the unit case 2. .
[0037]
In particular, in the present embodiment, the vertical ribs 23 projecting from the inner surfaces of the left and right side walls of the lower case 2B also bite into the elastic members 20 on the left and right side surfaces of the evaporator 3, so that the evaporator 3 is advantageously tightly held and fixed. be able to.
[0038]
Further, since the evaporator 3 is elastically held horizontally across the parting line between the upper case 2A and the lower case 2B, when the evaporator 3 is removed from the unit case 2 during maintenance, the lower case 2B is detached from the upper case 2A. Since a work space is secured below the upper case 2A, the evaporator 3 can be easily removed.
[0039]
When the lower case 2B is detached, the horizontal ribs 19 on the inner surfaces of the left and right side walls of the upper case 2A bite into the elastic members 20 on the left and right side surfaces of the evaporator 3 so that the evaporator 3 is not displaced by its own weight. The removal operation of the lower case 2B and the evaporator 3 can be easily performed.
[0040]
In particular, the parting line between the upper case 2A and the lower case 2B is formed substantially horizontally, and the evaporator 3 is disposed horizontally in a forward inclined state across the parting line. The lower case 2B can be removed by sliding it almost horizontally to the rear of the passenger compartment, and the lower case 2B can be removed more easily, and when the lower case 2B is removed, the front end of the evaporator 3 is located below the upper case 2A. Therefore, the evaporator 3 can be easily detached and the maintainability can be further improved.
[0041]
In addition, since the horizontal ribs 19 on the inner surfaces of the left and right side walls of the upper case 2A are inclined forward in accordance with the forwardly inclined arrangement of the evaporator 3, a plurality of vertical ribs are provided. It is possible to sufficiently secure the height and to regulate the slippage due to the weight of the evaporator 3 when the lower case 2B is detached.
[0042]
In addition, since the plurality of horizontal ribs 19 are provided in the vertical direction in this way, the rigidity of the left and right side walls of the upper case 2A can be increased, and the horizontal rib 19 whose front end is in contact with the lower edges of the left and right side walls of the upper case 2A Since the front end portion is formed along the lower edges of the left and right side walls, the rigidity of the lower edges of the left and right side walls can be increased and the outward deformation can be suppressed. As a result, the lateral rib 19 and the elastic member 20 can be suppressed. The evaporator 3 can be securely held and fixed, and the lowering of the weight of the evaporator 3 when the lower case 2B is removed can be reliably regulated.
