Description

本発明は小型冷却機設備に使用される冷却機用熱交換器に係り、更に詳しくは、内部に熱交換パイプ１６が挿入された熱交換部１１ａと、冷却水の排出通路部１１ｂと、を“Ｕ”字型通路で連通して棒形状の熱交換器本体１１を形成し、前記熱交換パイプ１６に冷媒注入用毛細管１７を二重管の形態で挿入し、熱交換パイプ１６の入口側に冷媒排出管１８と冷媒注入用毛細管１７とを挿入し、熱交換パイプ１６と冷媒注入用毛細管１７と冷媒排出管１８とを一体化した配管に集積して配管構造を単純化し、熱交換器本体１１の熱交換部１１ａと熱交換パイプ１６との間に水の流れを渦流式で誘導する螺旋形仕切り２０を設置し、熱交換パイプ１６と冷媒注入用毛細管１７との間に冷媒の流れを渦流で誘導する螺旋形仕切り２３を設置することで、熱交換器１０の体積を縮小した装置を構成し、配管連結部を通じた漏水の危険を減少させると共に、熱交換パイプ１６の電熱面積当たり熱效率を向上させることによって、熱交換器の体積を縮小した冷却機用熱交換器に関するものである。   The present invention relates to a heat exchanger for a cooler used in a small cooler facility, and more specifically, includes a heat exchange part 11a having a heat exchange pipe 16 inserted therein, and a cooling water discharge passage part 11b. A bar-shaped heat exchanger body 11 is formed by communicating with a “U” -shaped passage, and a refrigerant injection capillary tube 17 is inserted into the heat exchange pipe 16 in the form of a double pipe. The refrigerant discharge pipe 18 and the refrigerant injection capillary 17 are inserted into the pipe, and the heat exchange pipe 16, the refrigerant injection capillary 17 and the refrigerant discharge pipe 18 are integrated into an integrated pipe to simplify the pipe structure, and the heat exchanger A spiral partition 20 is installed between the heat exchange part 11a of the main body 11 and the heat exchange pipe 16 to guide the flow of water in a vortex manner, and the refrigerant flows between the heat exchange pipe 16 and the refrigerant injection capillary 17. Installing spiral partition 23 to guide the vortex The volume of the heat exchanger 10 is reduced, and the volume of the heat exchanger is reduced by reducing the risk of water leakage through the pipe connection part and improving the heat efficiency per electric heating area of the heat exchange pipe 16. The present invention relates to a heat exchanger for a cooling machine.

一般に家庭で観賞魚を飼育するのに使用する観賞魚用水槽や、活魚料理店で活魚や各種海産物を高密度で保管するために使用する活魚水槽には、水槽の水温を一定に維持するための冷却設備が設置される。一般にこのような冷却設備には工業用や他の産業用に比べて小さな設備が用いられる。   In general, aquarium fish tanks used for raising ornamental fish at home and live fish tanks used to store live fish and various marine products at high density in live fish restaurants are used to maintain a constant water temperature in the aquarium. The cooling equipment is installed. In general, such cooling equipment is smaller than that for industrial use or other industries.

図１に示すように、従来の冷却機用熱交換器１００は、ボックス形状を有する熱交換器本体１１０と、熱交換器本体１１０の上側に設置された冷却水流入管１１１と、冷却水排出管１１２と、熱交換器本体１１０の前方に設置された冷媒流入管１１３と、冷媒排出管１１４と、センサー連結管１１６と、を有する。前記センサー連結管１１６には電線１１８を具備する水温測定用センサー１１７が挿入される。   As shown in FIG. 1, a conventional heat exchanger 100 for a cooler includes a heat exchanger body 110 having a box shape, a cooling water inflow pipe 111 installed on the upper side of the heat exchanger body 110, and a cooling water discharge pipe. 112, a refrigerant inflow pipe 113 installed in front of the heat exchanger main body 110, a refrigerant discharge pipe 114, and a sensor connection pipe 116. A water temperature measuring sensor 117 having an electric wire 118 is inserted into the sensor connecting pipe 116.

また、熱交換器本体１１０の内部にはコイル状の熱交換パイプ１１５が設置され、熱交換パイプ１１５の両端が冷媒流入管１１３と冷媒排出管１１４とに接続され、熱交換パイプ１１５を通じた冷媒の流動を可能にする（例えば特許文献１参照）。同時にその外周部が冷却水の保持空間になり、水温測定用センサー１１７の検出部（図示せず）が冷却水保持空間に突出して水温を測定する。   In addition, a coiled heat exchange pipe 115 is installed inside the heat exchanger body 110, and both ends of the heat exchange pipe 115 are connected to the refrigerant inflow pipe 113 and the refrigerant discharge pipe 114, and the refrigerant through the heat exchange pipe 115 (See, for example, Patent Document 1). At the same time, the outer peripheral portion becomes a cooling water holding space, and a detection portion (not shown) of the water temperature measuring sensor 117 projects into the cooling water holding space to measure the water temperature.

図２に示すように、この構成の冷却機用熱交換器１００は、熱交換装置２００のケーシング２１０内部に挿入された熱交換器本体１１０と、コンプレッサー２２０と、放熱ファン２４０を具備する放熱器２３０と、によって構成される。冷媒流入管１１３と冷媒排出管１１４とが、冷媒配管によって放熱器２３０とコンプレッサー２２０とに夫々連結される。冷却水流入管１１１と冷却水排出管１１２とには冷却水の流入と排出のためのホース１１９が連結される。   As shown in FIG. 2, the heat exchanger 100 for a chiller having this configuration includes a heat exchanger body 110 inserted into the casing 210 of the heat exchange device 200, a compressor 220, and a heat radiating fan 240. 230. The refrigerant inflow pipe 113 and the refrigerant discharge pipe 114 are connected to the radiator 230 and the compressor 220 by refrigerant pipes, respectively. The cooling water inflow pipe 111 and the cooling water discharge pipe 112 are connected to a hose 119 for inflow and discharge of the cooling water.

コンプレッサー２２０による冷凍サイクルの作動によって、熱交換器本体１１０内部の熱交換パイプ１１５を通じて冷媒が吐出されると、冷却水流入管１１１から熱交換器本体１１０の内部に流入された水が一冷却され、冷却水排出管１１２を通じて熱交換器１００から外部に供給されることで、観賞魚水槽や活魚水槽に冷却水が供給される（例えば特許文献１参照）。   When the refrigerant is discharged through the heat exchange pipe 115 inside the heat exchanger main body 110 by the operation of the refrigeration cycle by the compressor 220, the water flowing into the heat exchanger main body 110 from the cooling water inflow pipe 111 is cooled once, The cooling water is supplied to the aquarium fish tank and the live fish tank by being supplied from the heat exchanger 100 to the outside through the cooling water discharge pipe 112 (see, for example, Patent Document 1).

しかし、従来の冷却機用熱交換器１００は、熱交換器本体１１０が箱型であり、体積が大きくなるという問題点があった。従って、熱交換器１００とコンプレッサー２２０と放熱器２３０とを使って熱交換装置２００を構成する場合、熱交換装置２００の寸法が大きくなり、小型化した熱交換装置２００を提供しにくいという問題点があった。
また、熱交換器１００の熱交換器本体１１０が箱型であることによって、冷却水流入管１１１を通じて流入された冷却水が熱交換器本体１１０の内部で滞溜し、冷却水の流速が遅い状態で熱交換パイプ１１５と熱交換を行うために、熱交換パイプ１１５の冷却効率が低いという問題点があり、このために熱交換器１００による冷却機の冷却性能が低いという問題点があった。 However, the conventional heat exchanger 100 for a cooler has a problem that the heat exchanger body 110 is box-shaped and the volume increases. Accordingly, when the heat exchange device 200 is configured using the heat exchanger 100, the compressor 220, and the radiator 230, the size of the heat exchange device 200 increases, and it is difficult to provide a miniaturized heat exchange device 200. was there.
Further, since the heat exchanger main body 110 of the heat exchanger 100 is box-shaped, the cooling water flowing in through the cooling water inflow pipe 111 is stagnated inside the heat exchanger main body 110, and the flow rate of the cooling water is slow. In order to exchange heat with the heat exchange pipe 115, there is a problem that the cooling efficiency of the heat exchange pipe 115 is low, and for this reason, there is a problem that the cooling performance of the cooler by the heat exchanger 100 is low.

冷却性能を向上させる目的で、熱交換パイプの電熱面積を広くするために熱交換パイプ１１５を数十回コイル状に巻いて熱交換器本体１１０を長くした熱交換器１００を制作したが、これは冷却性能の向上を達成するよりは、熱交換器１００の体積が大きくなり、熱交換パイプ１１５をコイル状に曲げるという難しい工程によって製造単価を上昇させる副作用を伴い、結局は熱交換パイプ１１５の素材になるステンレススチールとチタンとの無駄使いとなるものであった。   For the purpose of improving the cooling performance, in order to increase the electric heat area of the heat exchange pipe, the heat exchanger 100 was produced by winding the heat exchange pipe 115 into a coil shape several tens of times to make the heat exchanger body 110 longer. Rather than achieving improved cooling performance, the volume of the heat exchanger 100 becomes larger, with the side effect of increasing the manufacturing unit cost due to the difficult process of bending the heat exchange pipe 115 into a coil shape. It was a waste of stainless steel and titanium.

熱交換器本体１１０の内部を冷却水が流れるという熱交換器１００の特性上、熱交換装置２００の安全のためには、冷却水流入管１１１と、冷却水排出管１１２と、冷媒流入管１１３と、冷媒排出管１１４と、のような配管の連結部品に対する防水処理を確実する必要がある。漏水に対する危険性を解消するには、同一の防水処理条件下では配管の連結部品を小型化させることが最も望ましい方法と言える。   Due to the characteristics of the heat exchanger 100 in which cooling water flows inside the heat exchanger main body 110, a cooling water inflow pipe 111, a cooling water discharge pipe 112, a refrigerant inflow pipe 113, In addition, it is necessary to ensure waterproofing for the connecting parts of the piping such as the refrigerant discharge pipe 114. In order to eliminate the danger to water leakage, it can be said that it is the most desirable method to reduce the size of the connecting parts of the pipes under the same waterproof treatment conditions.

冷却水流入管１１１と冷却水排出管１１２には柔軟な材質のホース１１９が連結されるから、その密封作業は比較的容易である。一方、冷媒流入管１１３や冷媒排出管１１４には金属管が接続されるから、これに対する作業が困難であるので、熱交換器１００で発生する漏水は主に冷媒配管の連結部品が原因となっていた。
このように、熱交換器製品には、小型でありながらも優秀な冷却性能を示すと同時に、冷却機用熱交換器の性能に支障をもたらさずに冷媒配管の連結部品を小型化して漏水の危険を軽減させ、更に製造単価を削減して競争力を高めることが要求されている。 Since a flexible material hose 119 is connected to the cooling water inflow pipe 111 and the cooling water discharge pipe 112, the sealing operation is relatively easy. On the other hand, since a metal pipe is connected to the refrigerant inlet pipe 113 and the refrigerant outlet pipe 114, it is difficult to work on the pipe, and therefore, water leakage generated in the heat exchanger 100 is mainly caused by the connecting parts of the refrigerant pipe. It was.
In this way, heat exchanger products exhibit excellent cooling performance despite their small size, while at the same time reducing the size of the refrigerant pipe connection parts without affecting the performance of the heat exchanger for the chiller. There is a demand to reduce the risk and further increase competitiveness by reducing the manufacturing unit price.

It is characterized by that.

更に本発明は、統合連結管１４先端外周部にねじ部１４ａが形成され、ねじ部１４ａにＯリング１５ａを介して漏水防止キャップ１５が締結され、漏水防止キャップ１５を貫いて熱交換パイプ１６が挿入されることが好ましい。
また本発明は、熱交換パイプ１６の内側面と冷媒注入用毛細管１７の外側面との間に、冷媒注入用毛細管１７から吐出されて冷媒排出管１８に排出される冷媒を渦流式で循環させるための螺旋形仕切り２３が設置され、螺旋形仕切り２０による水の下降回転方向と、螺旋形仕切り２３による冷媒の上昇回転方向と、を相互に反対方向にすることが好ましい。 Further, according to the present invention , the threaded portion 14a is formed on the outer periphery of the integrated connecting pipe 14 and the water leakage preventing cap 15 is fastened to the threaded portion 14a via the O-ring 15a.

これらの効果によって、熱交換器本体の長さを縮小しても冷却性能の低下をもたらさなくなり、熱交換パイプの製造に必要となる資材を節減して、熱交換パイプの製造工程を簡素化し、熱交換器の製造単価削減に寄与する效果がある。 Further, water and spiral partition heat exchanger heat exchanging portion and the heat exchange pipe of the body that the flow of refrigerant induced by vortex, and respectively installed between the heat exchange pipe and the refrigerant injection capillary, by helical partition and lowering the rotation direction of the water, the increase in the rotation direction of the refrigerant by helical partition mutually by it to the opposite direction, is Effect of providing a heat exchanger cooling performance of the cooling device by the heat exchange pipe is improved is there.

図３に示すように、本発明の冷却機用熱交換器１０は、体積を縮小させるために、棒形状を有し、長さが延長された熱交換器本体１１を有する。熱交換器本体１１は、熱交換パイプ１６による冷却を行う熱交換部１１ａと冷却水の排出のための排出通路部１１ｂが“Ｕ”字型の通路で連通され、内部に一定な空間を確保することができるように熱交換器本体１１の前、後面がふくらんだ形状である。   As shown in FIG. 3, the heat exchanger 10 for a chiller of the present invention has a heat exchanger body 11 having a bar shape and an extended length in order to reduce the volume. In the heat exchanger body 11, a heat exchanging portion 11a for cooling by the heat exchanging pipe 16 and a discharge passage portion 11b for discharging the cooling water are communicated with each other by a “U” -shaped passage to secure a constant space inside. The front and rear surfaces of the heat exchanger main body 11 are inflated so as to be able to.

熱交換部１１ａの冷却水の流入部に該当する熱交換器本体１１の上端に冷却水流入管１２が突設され、冷却水流入管１２にはホースを連結させるためのホース連結部１２ａが設置されている。
また、排出通路部１１ｂは熱交換器本体１１の上端で横方向に伸長され、冷却水の排出部に該当する端部に冷却水排出管１３が突設され、前記冷却水排出管１３にはホースを連結させるためのホース連結部１３ａが設置されている。 A cooling water inflow pipe 12 protrudes from the upper end of the heat exchanger main body 11 corresponding to the cooling water inflow part of the heat exchanging part 11a, and the cooling water inflow pipe 12 is provided with a hose connecting part 12a for connecting a hose. Yes.
Further, the discharge passage portion 11b extends in the lateral direction at the upper end of the heat exchanger main body 11, and a cooling water discharge pipe 13 protrudes from an end corresponding to the cooling water discharge portion. A hose connecting portion 13a for connecting the hose is provided.

熱交換器本体１１の上端部を横方向に伸長するのは、熱交換器本体１１が棒形状であるために熱交換器本体１１の上端部分に冷却水流入管１２と冷却水排出管１３とを同時に設置する空間がないためであるから、冷却水流入管１２と冷却水排出管１３とを隣接して設置することができるか、あるいは各ホース連結部１２ａ、１３ａにホースを連結させる作業に支障がない場合には、熱交換器本体１１の上端部を横方向に伸長する必要がないことは自明である。   The reason why the upper end portion of the heat exchanger main body 11 extends in the lateral direction is that the heat exchanger main body 11 has a rod shape, and therefore the cooling water inflow pipe 12 and the cooling water discharge pipe 13 are provided at the upper end portion of the heat exchanger main body 11. This is because there is no space to be installed at the same time, so that the cooling water inflow pipe 12 and the cooling water discharge pipe 13 can be installed adjacent to each other, or there is an obstacle to the work of connecting the hose to each of the hose connection parts 12a and 13a. If not, it is obvious that there is no need to extend the upper end of the heat exchanger body 11 laterally.

熱交換器本体１１の上端前方側には冷却水流入管１２に近接して統合連結管１４及びセンサー連結管１９が設置され、センサー連結管１９を通じて水温測定用センサーのセンサーチップが冷却水と接触するように挿入される。熱交換器本体１１の上端部は前記熱交換部１１ａが概略三角形態を有しながら一定長さ程度前方側に突出形成されているので、これらを設置する空間を確保することができる。前記センサー連結管１９は冷却水排出管１３と接した排出通路部１１ｂに設置することもできる。   An integrated connecting pipe 14 and a sensor connecting pipe 19 are installed in front of the upper end of the heat exchanger body 11 in the vicinity of the cooling water inflow pipe 12, and the sensor chip of the water temperature measuring sensor comes into contact with the cooling water through the sensor connecting pipe 19. To be inserted. The upper end portion of the heat exchanger main body 11 is formed so as to protrude forward by a certain length while the heat exchanging portion 11a has a substantially triangular shape, so that a space for installing these can be secured. The sensor connection pipe 19 may be installed in the discharge passage portion 11 b in contact with the cooling water discharge pipe 13.

統合連結管１４の先端部外周に形成されたねじ部１４ａに漏水防止キャップ１５が締結され、漏水防止キャップ１５を貫いて熱交換パイプ１６が挿入される。熱交換パイプ１６の入口は冷媒注入用毛細管１７及び冷媒排出管１８がパッキング１６ａによって封鎖される。即ち、熱交換器本体１１の熱交換部１１ａに沿って、統合連結管１４、熱交換パイプ１６、冷媒注入用毛細管１７、及び冷媒排出管１８を一体化して集積した。   The water leakage prevention cap 15 is fastened to the screw portion 14 a formed on the outer periphery of the distal end portion of the integrated connection pipe 14, and the heat exchange pipe 16 is inserted through the water leakage prevention cap 15. The inlet of the heat exchange pipe 16 is sealed with a refrigerant injection capillary 17 and a refrigerant discharge pipe 18 by a packing 16a. That is, the integrated connecting pipe 14, the heat exchange pipe 16, the refrigerant injection capillary 17, and the refrigerant discharge pipe 18 are integrated and integrated along the heat exchange portion 11 a of the heat exchanger body 11.

本発明による熱交換器１０の内部構造は、図４及び図５にそれぞれ示すように、熱交換器本体１１の内部に沿って熱交換部１１ａと排出通路部１１ｂとが熱交換器本体１１をなすフレームによって両側に分割された状態で“Ｕ”字型の通路をなすように連通され、熱交換部１１ａ上部に突設された統合連結管１４の内側に熱交換パイプ１６が“逆Ｌ字型”で挿入され、熱交換パイプ１６の内部には冷媒注入用毛細管１７が挿入されて二重管を成す。   As shown in FIGS. 4 and 5, the internal structure of the heat exchanger 10 according to the present invention includes a heat exchanger 11 a and a discharge passage 11 b along the inside of the heat exchanger main body 11. The heat exchange pipe 16 is connected to the inside of the integrated connecting pipe 14 projecting from the upper part of the heat exchanging portion 11a so as to form a “U” -shaped passage in a state of being divided on both sides by the formed frame. The refrigerant | coolant injection | pouring capillary 17 is inserted in the inside of the heat exchange pipe 16, and a double pipe | tube is comprised.

熱交換パイプ１６の入口は冷媒排出管１８及び冷媒注入用毛細管１７とともにパッキング１６ａによって密封され、熱交換パイプ１６の末端部も封鎖される。熱交換パイプ１６の末端部まで延長された冷媒注入用毛細管１７から吐出された冷媒が、熱交換パイプ１６の内部空間を上昇した後、熱交換パイプ１６の入口と連結した冷媒排出管１８から排出されることで、冷媒の流動空間が形成される。   The inlet of the heat exchange pipe 16 is sealed together with the refrigerant discharge pipe 18 and the refrigerant injection capillary 17 by the packing 16a, and the end of the heat exchange pipe 16 is also sealed. The refrigerant discharged from the refrigerant injection capillary tube 17 extended to the end of the heat exchange pipe 16 rises in the internal space of the heat exchange pipe 16 and then is discharged from the refrigerant discharge pipe 18 connected to the inlet of the heat exchange pipe 16. As a result, a refrigerant flow space is formed.

図４及び図５の熱交換器本体１１の上端側に破線で表示した部分は、冷却水流入管１２及び冷却水排出管１３と連通される冷却水流入通路２１及び冷却水排出通路２２を示すものである。本来は図面に表れないが理解を助けるために表示したものである。
前記漏水防止キャップ１５はＯリング１５ａを介して統合連結管１４の先端部に締結されているが、このような漏水防止構造を冷却水流入管１２と冷却水排出管１３とに形成されたホース連結部１２ａ、１３ａに適用することができる。 4 and FIG. 5, a portion indicated by a broken line on the upper end side of the heat exchanger main body 11 shows the cooling water inflow passage 21 and the cooling water discharge passage 22 communicated with the cooling water inflow pipe 12 and the cooling water discharge pipe 13. It is. Although it does not originally appear in the drawing, it is displayed to aid understanding.
The water leakage prevention cap 15 is fastened to the tip of the integrated connection pipe 14 via an O-ring 15a. Such a water leakage prevention structure is connected to a hose formed in the cooling water inflow pipe 12 and the cooling water discharge pipe 13. It can be applied to the sections 12a and 13a.

また、図４及び図５に示す螺旋形仕切り２０は、冷却水流入管１２及び冷却水流入通路２１を通って熱交換部１１ａの内部に流入された水を渦流式で回転下降させるためのものである。このように螺旋形仕切り２０を形成すると、熱交換パイプ１６に沿って下降する水の流れを渦流式で誘導して冷媒による水の冷却性能を向上させることができる。   The spiral partition 20 shown in FIGS. 4 and 5 is used to rotate and descend the water that has flowed into the heat exchange section 11a through the cooling water inflow pipe 12 and the cooling water inflow passage 21 in a vortex manner. is there. When the spiral partition 20 is formed in this way, the flow of water descending along the heat exchange pipe 16 can be guided in a vortex manner to improve the water cooling performance by the refrigerant.

図６の（イ）に示すように、前記螺旋形仕切り２０は熱交換パイプ１６の外周面に沿って設置される。前記螺旋形仕切り２０は熱交換器本体１１と一体で射出成形することも、熱交換パイプ１６と一体で形成することもできるが、熱交換器本体１１と一体で射出成形する方が製造が容易であり、好ましい。   As shown in FIG. 6A, the spiral partition 20 is installed along the outer peripheral surface of the heat exchange pipe 16. The spiral partition 20 can be injection-molded integrally with the heat exchanger body 11 or can be formed integrally with the heat-exchange pipe 16, but it is easier to manufacture by injection-molding integrally with the heat exchanger body 11. It is preferable.

また、図６の（ロ）に示すように、前記熱交換パイプ１６の内側面と冷媒注入用毛細管１７の外側面の間に冷媒注入用毛細管１７から吐出されて冷媒排出管１８に吐出される冷媒を渦流式で循環及び上昇させるための螺旋形仕切り２３を設置し、冷媒による水の冷却性能をよりさらに向上させることができる。前記螺旋形仕切り２３は熱交換パイプ１６と一体で形成することも、熱交換パイプ１６と一体で形成することもできる。
螺旋形仕切り２０による水の下降回転方向と、螺旋形仕切り２３による冷媒の上昇回転方向と、を相互に反対方向にすることが冷却性能の向上にはより好ましい。 Also, as shown in FIG. 6B, the refrigerant is injected from the refrigerant injection capillary 17 between the inner surface of the heat exchange pipe 16 and the outer surface of the refrigerant injection capillary 17 and is discharged to the refrigerant discharge pipe 18. A spiral partition 23 for circulating and raising the refrigerant in a vortex manner can be installed to further improve the cooling performance of water by the refrigerant. The spiral partition 23 can be formed integrally with the heat exchange pipe 16 or can be formed integrally with the heat exchange pipe 16.
It is more preferable to improve the cooling performance by making the downward rotation direction of water by the spiral partition 20 and the upward rotation direction of the refrigerant by the spiral partition 23 opposite to each other.

上記の本発明の一実施例では、前記熱交換器本体１１が直線の棒形状を有するものを例示したが、図７の（イ）及び（ロ）に示すように、熱交換器本体１１の外部及び内部構造はそのままにした状態で、熱交換器本体１１の外観形状のみを“Ｌ”字型または“コ”の字型に延長して熱交換に必要な伝熱面積を拡大する、すなわち、熱交換部１１ａ及びその内部に挿入される熱交換パイプ１６の長さを伸長することもできる。   In the above embodiment of the present invention, the heat exchanger main body 11 has a straight rod shape. However, as shown in FIGS. Extending only the external shape of the heat exchanger main body 11 to the “L” shape or the “U” shape with the external and internal structures being left unchanged, that is, the heat transfer area required for heat exchange is expanded. The length of the heat exchanging portion 11a and the heat exchanging pipe 16 inserted therein can also be extended.

以下、本発明の冷却機用熱交換器の作用を添付された図面を参照して詳細に説明する。
図８に示すように、コンプレッサー２２０と放熱ファン２４０を具備する放熱器２３０と本発明による熱交換器１０とを、熱交換装置２００のケーシング２１０内部に挿入し、冷媒注入用毛細管１７と冷媒排出管１８とを、放熱器２３０とコンプレッサー２２０とそれぞれ連結すると共に、冷却水流入管１２と冷却水排出管１３とに冷却水の流入と排出のためのホースを連結設置する。 Hereinafter, the operation of the heat exchanger for a cooler according to the present invention will be described in detail with reference to the accompanying drawings.
As shown in FIG. 8, the heat exchanger 230 according to the present invention and the heat exchanger 230 having the compressor 220 and the heat radiating fan 240 are inserted into the casing 210 of the heat exchanging device 200, and the refrigerant injection capillary 17 and the refrigerant discharge are inserted. The pipe 18 is connected to the radiator 230 and the compressor 220, and hose for cooling water inflow and discharge is connected to the cooling water inflow pipe 12 and the cooling water discharge pipe 13.

本発明による熱交換器１０を、熱交換装置２００のケーシング２１０に設置する場合、本発明による熱交換器１０が棒形状であるので体積が小さくなるだけでなく、コンプレッサー２２０や放熱器２３０が設置されて余った狭い空間に熱交換器１０を設置することで、ケーシング２１０を縮小して、熱交換器１０を小型化することができる。   When the heat exchanger 10 according to the present invention is installed in the casing 210 of the heat exchange device 200, the heat exchanger 10 according to the present invention has a rod shape, so that not only the volume is reduced, but also the compressor 220 and the radiator 230 are installed. By installing the heat exchanger 10 in an excessively narrow space, the casing 210 can be reduced and the heat exchanger 10 can be downsized.

本発明による熱交換器１０をコンプレッサー２２０及び放熱器２３０と共に設置した後、コンプレッサー２２０を駆動して冷凍サイクルを作動させると、コンプレッサー２２０から放熱器２３０を経て冷媒注入用毛細管１７に流入した冷媒が、熱交換パイプ１６の末端部で吐出されて熱交換パイプ１６に沿って上昇すると共に、冷却水流入管１２に流入した水が熱交換器本体１１の熱交換部１１ａ内側に沿って下降することによって、熱交換部１１ａの内部の熱交換パイプ１６によって水が冷却がされる。
熱交換パイプ１６を上昇しながら冷却に使用された冷媒は熱交換パイプ１６の入口側に連結された冷媒排出管１８から排出され、コンプレッサー２２０に再流入する。冷却された水は、排出通路部１１ｂから冷却水排出管１３に排出される。 After the heat exchanger 10 according to the present invention is installed together with the compressor 220 and the radiator 230, when the compressor 220 is driven to operate the refrigeration cycle, the refrigerant flowing from the compressor 220 through the radiator 230 into the refrigerant injection capillary 17 is discharged. As the water discharged into the end portion of the heat exchange pipe 16 rises along the heat exchange pipe 16 and flows into the cooling water inflow pipe 12, the water falls along the inside of the heat exchange section 11 a of the heat exchanger body 11. The water is cooled by the heat exchange pipe 16 inside the heat exchange part 11a.
The refrigerant used for cooling while ascending the heat exchange pipe 16 is discharged from the refrigerant discharge pipe 18 connected to the inlet side of the heat exchange pipe 16 and flows into the compressor 220 again. The cooled water is discharged from the discharge passage portion 11b to the cooling water discharge pipe 13.

本発明による熱交換器１０は、熱交換パイプ１６による熱交換部１１ａと冷却水の排出通路部１１ｂとが“Ｕ”字型の通路で連通されているので、熱交換パイプ１６の外周を下降する水と、熱交換パイプ１６の内部を上昇する冷媒とが対向冷却方式によって熱交換部１１ａの内側で効率的に熱交換し、迅速な冷却水の冷却が行われる。   In the heat exchanger 10 according to the present invention, the heat exchanging portion 11a by the heat exchanging pipe 16 and the cooling water discharge passage portion 11b communicate with each other through a "U" -shaped passage. The water that rises and the refrigerant that rises inside the heat exchange pipe 16 efficiently exchange heat inside the heat exchange unit 11a by the counter cooling method, and cooling of the cooling water is performed quickly.

本発明の熱交換器１０は、熱交換器本体１１に熱交換パイプ１６を直線形で挿入することによって熱交換パイプ１６の長さを縮小させても冷却性能の低下させないので、熱交換パイプ１６の製造資材を節約することができる。
また、熱交換パイプ１６の長さを伸張して伝熱面積を拡大する場合に、コイル状の熱交換器を用いる場合はパイプを数十回巻き込む難しい作業が必要であるが、本発明の場合は線形の熱交換パイプ１６を冷媒注入用毛細管１７とともに直角に曲げる作業を１回ないし３回行えば良く、大型の熱交換器を容易に且つ安価に製造できる。 Since the heat exchanger 10 of the present invention does not deteriorate the cooling performance even if the length of the heat exchange pipe 16 is reduced by inserting the heat exchange pipe 16 into the heat exchanger body 11 in a straight line, the heat exchange pipe 16 Can save manufacturing materials.
Further, when the heat transfer pipe 16 is extended to expand the heat transfer area, when using a coiled heat exchanger, a difficult work of winding the pipe several tens of times is necessary. The linear heat exchange pipe 16 and the refrigerant injection capillary 17 need only be bent once or three times, and a large heat exchanger can be manufactured easily and inexpensively.

図６の（イ）及び（ロ）に示すように、熱交換器本体１１の熱交換部１１ａと熱交換パイプ１６との間に水を渦流式で回転下降させる螺旋形仕切り２０を設置し、熱交換パイプ１６と冷媒注入用毛細管１７との間に冷媒を渦流式で回転上昇させる螺旋形仕切り２３を設置した場合、水と冷媒の熱交換作用をさらに促進させることができ、これによって熱交換パイプ１６による冷却水の冷却性能をより大きく向上することができる。   As shown in (a) and (b) of FIG. 6, a spiral partition 20 is installed between the heat exchange part 11 a of the heat exchanger body 11 and the heat exchange pipe 16 to rotate and descend water in a vortex manner. When a spiral partition 23 is installed between the heat exchange pipe 16 and the refrigerant injection capillary 17 to rotate and lift the refrigerant in a vortex manner, the heat exchange action of water and the refrigerant can be further promoted, thereby heat exchange. The cooling performance of the cooling water by the pipe 16 can be greatly improved.

更に、従来の技術内容で既に説明したように、熱交換器本体１１の内部に冷却水が保存されているという熱交換器１０の特性上、熱交換装置２００の安全のためには配管の連結部品に対する漏水問題を解決しなければならない。本発明による熱交換器１０は冷媒注入用毛細管１７と冷媒排出管１８とが熱交換パイプ１６の内部に挿入されているから、漏水の主な要因になる冷媒配管の連結部品を従来の場合と比べて縮小することができる。これによって熱交換器１０の構造を単純化させることができるだけでなく、冷媒配管の連結部品による漏水の危険も減少させることができる。   Further, as already described in the conventional technical contents, because of the characteristic of the heat exchanger 10 that the cooling water is stored in the heat exchanger main body 11, the piping of the heat exchanger 200 is connected for safety. The water leakage problem for parts must be solved. In the heat exchanger 10 according to the present invention, the refrigerant injection capillary 17 and the refrigerant discharge pipe 18 are inserted into the heat exchange pipe 16, so that the connecting parts of the refrigerant pipe which are the main causes of water leakage are different from the conventional case. It can be reduced in comparison. Thereby, not only can the structure of the heat exchanger 10 be simplified, but also the risk of water leakage due to the connecting parts of the refrigerant piping can be reduced.
