Abstract

<P>PROBLEM TO BE SOLVED: To miniaturize a heat generation apparatus and to improve dielectric strength and a thermal efficiency. <P>SOLUTION: A combination of a heating element 9, a spring terminal 10 and a flat terminal 11 is stored in a case 1 and an upper lid 2 is placed on the case 1. The case 1 is equipped with a heat radiation body 4 to assemble the heat generation apparatus. A part of the heat radiation body 4 to be attached to the case 1 is equipped with a flat heat receiving plane 4a to be brought into contact with the substantially whole area of the top of the upper lid 2 to increase a thermal efficiency. The upper lid 2 has an insulation plate 2a with a collar edge 2b on the periphery. A creepage distance in length of the thickness of the insulation plate 2a plus twice the rising height of the inside of the collar edge 2b is secured between a heating unit 3 and the heat radiation body 4. Consequently, sufficient dielectric strength is obtained even in thin thickness of the upper lid 2 and a thermal efficiency between the heating unit 3 and the heat radiation body 4 is increased by thinning the thickness of the upper lid. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

本発明は、液体式電子蚊取器の吸液芯のような被加熱物を加熱又は加温する液体蒸散器用発熱装置に関する。   The present invention relates to a heating device for a liquid evaporator that heats or heats an object to be heated such as a liquid absorption core of a liquid electronic mosquito trap.

液体式電子蚊取器の発熱装置には、発熱素子として正特性サーミスタ素子が使用され、正特性サーミスタ素子の発する熱を放熱筒に伝え、放熱筒内に挿入された吸液芯を加温する方式が用いられている。図５は、特許文献１に記載された発熱装置の例である。
この例では、発熱素子２１と、該素子２１の両面に配設する電極板２２，２３の対と、絶縁性伝熱板２４と、金属体２５との組合せを用い、これを絶縁ケース２６に取付けている。ところで、この構造によるときには、正特性サーミスタ素子２１の発した熱は、絶縁性伝熱板２４を通して金属体２５に伝えられる。金属体２５は、貫通孔２７を有する放熱筒である。 A heat generating device of a liquid electronic mosquito trap uses a positive temperature coefficient thermistor element as a heat generating element. The heat generated by the positive temperature coefficient thermistor element is transmitted to the heat radiating tube to heat the liquid absorption core inserted in the heat radiating tube. The method is used. FIG. 5 is an example of the heat generating device described in Patent Document 1.
In this example, a combination of a heating element 21, a pair of electrode plates 22 and 23 disposed on both sides of the element 21, an insulating heat transfer plate 24, and a metal body 25 is used as an insulating case 26. It is installed. By the way, with this structure, the heat generated by the positive temperature coefficient thermistor element 21 is transmitted to the metal body 25 through the insulating heat transfer plate 24. The metal body 25 is a heat radiating cylinder having a through hole 27.

貫通孔２７内には、被加熱物として薬液の吸液芯が挿入される。特許文献１には、発熱素子と金属体との熱結合を樹脂を用いずに行うことで、発熱素子の自己発熱量は樹脂を介して周囲の不要部分へ熱伝達することがなく、そのほとんどの発熱量を弾性体電極板で圧接する各構成部材を介して、金属体の筒状の貫通孔に集中して熱伝達できることから、熱伝達にロスの少ない発熱装置を容易に実現できるという効果が強調されている。   In the through hole 27, a liquid absorption core for a chemical solution is inserted as an object to be heated. In Patent Document 1, by performing the thermal coupling between the heat generating element and the metal body without using a resin, the self-heat generation amount of the heat generating element does not transfer heat to unnecessary surrounding portions through the resin, most of them. Heat can be concentrated and transferred to the cylindrical through-hole of the metal body through the constituent members pressed against each other by the elastic electrode plate, so that it is possible to easily realize a heat generating device with little loss in heat transfer. Is emphasized.

しかしながら、上記構造によるときには、放熱筒である金属体の表面が外気に晒されることから、金属体の熱が外気中に放散されて熱伝達には当然にロスが生ずることになる。一方、特許文献２には、放熱筒であるパイプをケース内に設置する正特性サーミスタ装置が記載されている。図６において、発熱素子３１は、対の電極３２，３３に挾んでケース３４の凹部３５内に設置される。   However, when the above structure is used, the surface of the metal body, which is a heat radiating cylinder, is exposed to the outside air, so that the heat of the metal body is dissipated into the outside air and a loss of heat transfer is naturally generated. On the other hand, Patent Document 2 describes a positive temperature coefficient thermistor device in which a pipe that is a radiating cylinder is installed in a case. In FIG. 6, the heating element 31 is installed in the recess 35 of the case 34 so as to sandwich the pair of electrodes 32 and 33.

特許文献２によれば、放熱筒であるパイプ３６をケース３４内に収容し、ケース３４にはアルミナ等の絶縁性無機材料を使用することによって、絶縁樹脂を介して絶縁ケース３４の全体に正特性サーミスタ素子３１からの発熱が伝わることによる問題点を解消したというのである。たしかに、熱伝導効率のよいアルミナをケース材料に用いたときに、発熱素子３１の熱は、ケース３４を通じてパイプ３６に効率よく伝えられるかも知れないが、ケース３４の全体も暖められ、ケース表面から外気へ放散される熱量のロスは決して無視できるレベルではないものと思われる。   According to Patent Document 2, a pipe 36 that is a heat radiating cylinder is accommodated in a case 34, and an insulating inorganic material such as alumina is used for the case 34, so that the entire insulating case 34 can be properly aligned via an insulating resin. That is, the problem caused by the heat generated from the characteristic thermistor element 31 is solved. Certainly, when alumina with good heat conduction efficiency is used as the case material, the heat of the heating element 31 may be efficiently transferred to the pipe 36 through the case 34, but the entire case 34 is also warmed, and from the case surface. It seems that the loss of heat dissipated to the outside air is not negligible.

このような先行技術の問題点を指摘し、これらの問題を解決するため、ケースを通じて大気中に放散される熱量のロスを極力抑えて熱の利用効率を高めた発熱装置が提案された（特許文献３参照）。   In order to solve the problems of the prior art and solve these problems, a heat generating device was proposed in which the loss of heat dissipated into the atmosphere through the case is suppressed as much as possible to improve the heat utilization efficiency (patent) Reference 3).

特許文献３による発熱装置は、図７に示すように熱伝導体４１と、発熱ユニット４２とを断熱性を有する中空のケース４３内に有する発熱装置であって、ケース４３は、第１室４６と第２室４７との２室に区画され、第１室４６に開口４８を有し、開口４８は、被加熱物である吸液芯を挿入する孔であり、熱伝導体４１は、ケース４３の両室４６、４７間に跨ってケース４３内に設置され、放熱部４９と受熱部５０と連結部５１とを有し、放熱部４９は、第１室４６の開口４８に連通して被加熱物の挿入用貫通孔を形成し、受熱部５０は、ケース４３の第２室４７に設置され、発熱ユニット４２の発する熱を受熱するものであり、連結部５１は、放熱部４９と受熱部５０とをつなぐ部分であり、両室間に跨って設置され、発熱ユニット４２は、発熱素子５３と絶縁性伝熱板５６とを有し、正特性サーミスタ素子５３は、対の給電端子５４、５５間に挾んでケース４３の第２室４７に設置され、給電により発熱し、絶縁性伝熱板５０は、発熱素子５３と熱伝導体４１とを電気的に絶縁して発熱素子５３の発熱を熱伝導体４１の受熱部５０に伝えるようにしたものである。   As shown in FIG. 7, the heat generating device according to Patent Document 3 is a heat generating device having a heat conductor 41 and a heat generating unit 42 in a hollow case 43 having heat insulation properties, and the case 43 includes a first chamber 46. And the second chamber 47. The first chamber 46 has an opening 48. The opening 48 is a hole for inserting a liquid absorbent core as a heated object. 43 is installed in the case 43 across both chambers 46 and 47, and has a heat radiating portion 49, a heat receiving portion 50, and a connecting portion 51, and the heat radiating portion 49 communicates with the opening 48 of the first chamber 46. A through-hole for inserting an object to be heated is formed, and the heat receiving part 50 is installed in the second chamber 47 of the case 43 and receives heat generated by the heat generating unit 42. It is the part that connects the heat receiving part 50 and is installed across the two rooms. The positive temperature coefficient thermistor element 53 is sandwiched between a pair of power supply terminals 54 and 55 and is installed in the second chamber 47 of the case 43. The heat generating element 53 and the insulating heat transfer plate 56 generate heat by power supply and are insulated. The heat conductive plate 50 electrically insulates the heat generating element 53 and the heat conductor 41 so as to transmit heat generated by the heat generating element 53 to the heat receiving portion 50 of the heat conductor 41.

特許文献３に記載の構造によるときには、発熱ユニット４２の発する熱を直接熱伝導体４１に伝えて放熱部４９の筒を発熱させることができ、熱伝導体４１の周囲への放熱量を減少することができる。しかし、ユーザーの要望は、可能な限りどこまでも小型化することであり、また、少ない部品点数で、絶縁耐力、熱効率に優れた発熱装置の開発が強く要望されるが、所望の絶縁耐力を得るために、且つ発熱ユニットと、放熱筒間に一定の沿面距離を確保しようとした場合には、小型化にはどうしても限界があり、一定以上の小型化の要望には応じきれないという問題があった。
特開平７−３２０８４９号公報 特開平８−７８２０７号公報 特開平１０−２２３３５５公報 When the structure described in Patent Document 3 is used, the heat generated by the heat generating unit 42 can be directly transmitted to the heat conductor 41 to heat the tube of the heat radiating portion 49, and the amount of heat released to the periphery of the heat conductor 41 is reduced. be able to. However, the user's desire is to reduce the size as much as possible, and there is a strong demand for the development of a heat generating device with a small number of parts and excellent dielectric strength and thermal efficiency. To obtain the desired dielectric strength In addition, when trying to secure a certain creepage distance between the heat generating unit and the heat radiating cylinder, there is a problem that downsizing is inevitably limited and it is not possible to meet the demand for downsizing beyond a certain level. .

解決しようとする問題点は、従来の発熱装置の構造では、小型化、絶縁耐力、熱効率の向上には限界があったという点である。   The problem to be solved is that the conventional structure of the heat generating device has limitations in miniaturization, dielectric strength, and thermal efficiency.

本発明による発熱装置は、発熱素子を含む発熱ユニットと、放熱筒（本発明においては放熱体）との間の沿面距離を一定以上に確保し、しかも発熱ユニットと、放熱体間の熱効率の向上を図るため、発熱ユニットと、放熱体との間を電気的に隔離する絶縁体として発熱ユニットのケースの上蓋に絶縁板を用い、しかも、その絶縁板の周縁に下向きに張出した鍔縁を一体に設けた点を最大の特徴とする。   The heat generating device according to the present invention secures a creepage distance between the heat generating unit including the heat generating element and the heat radiating cylinder (the heat radiating body in the present invention) more than a certain level, and further improves the thermal efficiency between the heat generating unit and the heat radiating body. Therefore, an insulating plate is used for the top lid of the case of the heat generating unit as an insulator that electrically isolates the heat generating unit and the heat radiating body, and a flange that protrudes downward is integrated with the periphery of the insulating plate. The point provided in is the greatest feature.

本発明の発熱装置は、発熱ユニットをケース内に収め、ケースを上蓋で施蓋することによって、発熱ユニットを小型にまたコンパクトにまとめられ、このケースに放熱体を組みつけることによって発熱装置を組立てることができ、また、ケースに組み付ける放熱体の一部には、上蓋の上面のほぼ全面に接触する平坦な受熱面を設けることによって熱効率を高めることができ、さらに、上蓋は、周縁に鍔縁を有するため、発熱ユニットと、放熱体間の沿面距離として、絶縁板の厚みに鍔縁の内側の立上り高さの２倍以上を加えた長さの距離を確保でき、したがって、上蓋の厚みが薄くても十分な絶縁耐力が得られ、上蓋の厚みを薄くすることによって、さらに発熱ユニットと、放熱体間の熱効率を高めることができる。   In the heat generating device of the present invention, the heat generating unit is housed in a case, and the case is covered with an upper lid, so that the heat generating unit can be made compact and compact, and the heat generating device is assembled by assembling a heat radiator to the case. In addition, a part of the heat dissipating body assembled to the case can be provided with a flat heat receiving surface that contacts almost the entire upper surface of the upper lid, and the thermal efficiency can be improved. Therefore, as the creeping distance between the heat generating unit and the radiator, it is possible to secure a distance of a length obtained by adding at least twice the rising height inside the flange to the thickness of the insulating plate. Even if it is thin, sufficient dielectric strength can be obtained, and by reducing the thickness of the upper lid, it is possible to further increase the thermal efficiency between the heat generating unit and the radiator.

小型でしかも絶縁耐力を高めるという目的を、発熱ユニットのケースの上蓋に、立下りとしての鍔縁を周縁に有する絶縁板を用いることで部品点数を増加させずに実現した。   The objective of reducing the size and increasing the dielectric strength was realized without increasing the number of parts by using an insulating plate having a flange edge as a falling edge on the upper lid of the case of the heat generating unit.

図１は、本発明に係る発熱装置の要部における分解斜視図である。図１において、本発明による発熱装置は、ケース１と、その上蓋２と、発熱ユニット３と、放熱体４との組合せから構成されるものである。ケース１は、電気絶縁材料をもって一定形状に成形された無蓋の有底角型の中空容器であり、発熱ユニット３を収容するとともに、放熱体４を定位置に保持するものである。   FIG. 1 is an exploded perspective view of a main part of a heat generating device according to the present invention. In FIG. 1, the heat generating device according to the present invention comprises a combination of a case 1, an upper lid 2, a heat generating unit 3, and a radiator 4. The case 1 is a non-bottomed rectangular hollow container formed into a fixed shape with an electrically insulating material. The case 1 accommodates the heat generating unit 3 and holds the radiator 4 in a fixed position.

ケース１の内底には、発熱ユニット３の組合わせを保持するリブ５が上向きに突出形成されており、ケース１の外壁には、放熱体４に設けた対のクリップ６、６を差し込む保持溝７、７が外壁の対向面に形成されている。なおケース１には、ケース１を電子蚊取器などの機器への取付けるためのホルダー８を備えている。この実施例では、リブ５は、発熱ユニット３の４周を支える枠型の突条をもって形成した例を示しているが必ずしも枠型に限らず、発熱ユニット３の少なくとも対向二面を支えることによって、発熱ユニット３を定位置に保持できる。   A rib 5 that holds the combination of the heat generating units 3 is formed on the inner bottom of the case 1 so as to protrude upward, and a pair of clips 6 and 6 provided on the radiator 4 are inserted into the outer wall of the case 1. Grooves 7 are formed on the opposing surface of the outer wall. The case 1 is provided with a holder 8 for attaching the case 1 to a device such as an electronic mosquito trap. In this embodiment, the rib 5 is formed with a frame-shaped protrusion that supports the four circumferences of the heat generating unit 3. However, the rib 5 is not necessarily limited to the frame shape, and by supporting at least two opposing surfaces of the heat generating unit 3. The heat generating unit 3 can be held in a fixed position.

発熱ユニット３は、発熱素子（正特性サーミスタ）９と、ばね端子１０と、平端子１１との組合せである。ばね端子１０は、電極面１０ａの両端又は片方を下向きに折曲して電極面１０ａにばね作用を付与した電極端子であり、電極面１０ａには、数個のブリスター１０ｂを下向きに突設し、発熱素子９が接触する電極面にブリスター１０ｂの凹所を設けて発熱素子９を電極面１０ａに確実に接触さている。平端子１１は、平坦な電極面１１ａを有する電極端子である。   The heat generating unit 3 is a combination of a heat generating element (positive characteristic thermistor) 9, a spring terminal 10, and a flat terminal 11. The spring terminal 10 is an electrode terminal in which both ends or one side of the electrode surface 10a is bent downward to give a spring action to the electrode surface 10a, and several blisters 10b project downward from the electrode surface 10a. The recess of the blister 10b is provided on the electrode surface with which the heating element 9 comes into contact, so that the heating element 9 is reliably in contact with the electrode surface 10a. The flat terminal 11 is an electrode terminal having a flat electrode surface 11a.

ばね端子１０、発熱素子９、平端子１１の順にケース１のリブ５の突条間に収納し、図２に示すように、ばね端子１０及び平端子１１に備えた各給電端子１０ｃ、１１ｂをケース１の底の***（図示略）から下方に引き出した状態でばね端子１０と平端子１１間に発熱素子９を保持した状態でケース１の上面開口を上蓋２で施蓋する。   The spring terminal 10, the heating element 9, and the flat terminal 11 are housed in this order between the ribs 5 of the case 1, and as shown in FIG. 2, the power supply terminals 10 c and 11 b provided on the spring terminal 10 and the flat terminal 11 are provided. The upper opening of the case 1 is covered with the upper lid 2 while the heating element 9 is held between the spring terminal 10 and the flat terminal 11 in a state of being drawn downward from a small hole (not shown) at the bottom of the case 1.

本発明において、ケース１の上蓋２は絶縁板であり、角型の絶縁板２ａが一定の高さで立ち上がる鍔淵２ｂでその四周縁が支えられたものである。本発明においては、この鍔縁２ｂをリブ５に嵌合させ、鍔縁２ｂをリブ５の外面に係止させ、絶縁板２ａを圧下し、ばね端子１０のばね力を上向きに作用させてばね端子１０の電極面１０ａと、平端子１１の電極面１１ａとの間に発熱素子９を緊締させるとともに、平端子１１を上蓋２の絶縁板２ａの下面に圧接してケース１の上面開口を施蓋する。   In the present invention, the upper lid 2 of the case 1 is an insulating plate, and the four peripheral edges thereof are supported by a hook 2b where a square insulating plate 2a rises at a constant height. In the present invention, the flange 2b is fitted to the rib 5, the flange 2b is locked to the outer surface of the rib 5, the insulating plate 2a is pressed down, and the spring force of the spring terminal 10 is applied upward to cause the spring. The heating element 9 is fastened between the electrode surface 10a of the terminal 10 and the electrode surface 11a of the flat terminal 11, and the upper surface of the case 1 is opened by pressing the flat terminal 11 against the lower surface of the insulating plate 2a of the upper lid 2. Cover.

一方、この実施例において、放熱体４は、熱伝導性に優れた一枚の金属板の裁断、並びに折り曲げによって筒状に組立てられたものであり、放熱体４の外周一部には、上蓋２の絶縁板２ａの上面のほぼ全面に接触させる平坦な受熱面４ａが形成され、該受熱面４ａを中心にその両延長部分の板面を互いに向き合わせに湾曲させ、その両端縁を互いにつき合わせて断面が略半円形の筒状に組立てたものである。   On the other hand, in this embodiment, the radiator 4 is assembled into a cylindrical shape by cutting and bending a single metal plate having excellent thermal conductivity. A flat heat receiving surface 4a is formed in contact with almost the entire upper surface of the second insulating plate 2a, the plate surfaces of both extension portions are curved to face each other around the heat receiving surface 4a, and both end edges are attached to each other. In addition, the cross section is assembled into a substantially semicircular cylindrical shape.

また、筒の開口縁となる放熱体４の受熱面４ａの両縁には、クリップ６、６を有している。クリップ６は、放熱体４の受熱面４ａの両縁より舌状に延びる金属板の板面を下向きに折曲することによって形成され、金属板の有するばね作用を利用して両クリップ６，６を互いに接近する方向に付勢したものであり、放熱体４の受熱面４ａをケース１の上蓋２の上面にあてがい、両クリップ６、６をケース１に跨らせ、放熱体４を上方から加圧して両クリップ６、６をケース１の両保持溝７，７内に圧入する。   Further, clips 6 and 6 are provided on both edges of the heat receiving surface 4a of the radiator 4 serving as the opening edge of the cylinder. The clip 6 is formed by bending downward a plate surface of a metal plate extending in a tongue shape from both edges of the heat receiving surface 4a of the heat radiating body 4, and using the spring action of the metal plate, both the clips 6, 6 The heat receiving surface 4a of the radiator 4 is applied to the upper surface of the upper lid 2 of the case 1, the clips 6 and 6 are straddled over the case 1, and the radiator 4 is viewed from above. The clips 6 and 6 are pressed into the holding grooves 7 and 7 of the case 1 by applying pressure.

なお、ケース１の保持溝７の内壁面には、角型の突子７ａが突設され、この突子７ａと対応してクリップ６の板面には、***６ａを開口しておくことによって、クリップ６を保持溝７内に差し込んだときに、突子７ａが***６ａに嵌合してクリップ６は、保持溝７内に定着し、したがって、放熱体４は、図３（ａ）、（ｂ）に示すように受熱面４ａが上蓋２に密着した状態でケース１に一体的に組みつけられる。もっとも、***６ａは、クリップ６に設ける場合に限らず、この関係は逆であっても良い。すなわち、図４（ａ）に示すようにクリップ６の一部を切り起して内側に突出する突子６ｂを設け、対応するケース１の側壁には、***７ｂを形成し、図４（ｂ）に示すように、ケース１の***７ｂ内にクリップ６の突子６ｂを係合させてもよい。いずれにしても***内に突子が係合してケースと放熱体４とが一体的に結合され、ケースの保持溝から放熱体４のクリップの脱落が防止される。   A rectangular protrusion 7a is provided on the inner wall surface of the holding groove 7 of the case 1, and a small hole 6a is opened on the plate surface of the clip 6 corresponding to the protrusion 7a. When the clip 6 is inserted into the holding groove 7, the protrusion 7a is fitted into the small hole 6a, and the clip 6 is fixed in the holding groove 7. Therefore, the heat dissipating body 4 is shown in FIG. As shown in (b), the heat receiving surface 4a is assembled to the case 1 in a state where the heat receiving surface 4a is in close contact with the upper lid 2. However, the small hole 6a is not limited to being provided in the clip 6, and this relationship may be reversed. That is, as shown in FIG. 4 (a), a protrusion 6b that cuts out a part of the clip 6 and protrudes inward is provided, and a small hole 7b is formed in the side wall of the corresponding case 1, and FIG. ), The protrusion 6b of the clip 6 may be engaged in the small hole 7b of the case 1. In any case, the protrusion engages in the small hole so that the case and the heat radiating body 4 are integrally coupled, and the clip of the heat radiating body 4 is prevented from dropping from the holding groove of the case.

以上実施例１においては、ケース１上に筒状の放熱体４を組み付けた例を図示したが、発熱装置として電子蚊取器などに組み付けるときには、必ずしもケース１上に放熱体４が設置された状態で使用されるわけではない。通常は、放熱体４の開口を上下方向に向けた姿勢で機器に組みつけられ、蒸散液を吸液させた吸液芯は垂直姿勢で、放熱体４の下部開口から放熱体４内に差し込まれる。本明細書において、上下の区別はあくまで説明の都合上による区別である。   In the first embodiment, the example in which the cylindrical heat radiating body 4 is assembled on the case 1 is illustrated. However, when the heat radiating device is assembled to an electronic mosquito trap or the like, the heat radiating body 4 is not necessarily installed on the case 1. It is not used in the state. Usually, the radiator 4 is assembled to the apparatus with the opening of the radiator 4 facing up and down, and the liquid absorption core that absorbs the evaporation liquid is inserted into the radiator 4 from the lower opening of the radiator 4 in the vertical attitude. It is. In the present specification, the distinction between upper and lower is only for the convenience of description.

本発明の発熱装置を例えば電子蚊取器の器体に取付け、電子蚊取器の吸液芯を放熱体４の筒内に差し込んだ状態で、両給電端子１０ｃ、１１ｂに通電すると、発熱素子９は、両端子１０、１１の電極板から給電されて発熱し、その熱は、上蓋２を通じて放熱体４に伝えられ、放熱体４の筒内に挿入された吸液芯（図示略）を加熱または加温し、吸液芯に含まれた薬剤を蒸散させる。   When the heating device of the present invention is attached to the body of an electronic mosquito trap, for example, and the power feeding terminal 10c, 11b is energized with the liquid absorption core of the electronic mosquito trap inserted in the cylinder of the radiator 4, the heating element 9 is supplied with power from the electrode plates of both terminals 10, 11 to generate heat, and the heat is transmitted to the heat radiating body 4 through the upper lid 2, and a liquid absorbing core (not shown) inserted into the cylinder of the heat radiating body 4 is used. Heat or warm to evaporate the drug contained in the absorbent core.

本発明においては、放熱体４には、図３（ｂ）に示すようにケース１を施蓋する上蓋２のほぼ全面を覆う大きさの受熱面４を設けたために、ケース１の上蓋２から外気に放出される熱量の損失量は少なく、したがって、熱効率を従来に比べて大幅に向上することができる。   In the present invention, the heat radiating body 4 is provided with a heat receiving surface 4 having a size covering almost the entire surface of the upper lid 2 that covers the case 1 as shown in FIG. There is little loss of the amount of heat released to the outside air, so that the thermal efficiency can be greatly improved compared to the conventional case.

また、上蓋２の下面周縁には、ケース１の開口縁内に嵌合する鍔縁２ｂを設けたため、発熱ユニット３と、放熱体４の受熱面４ａ間は、上蓋の絶縁板２ａの厚みに、鍔縁２ｂの内側の立ち上がり高さの２倍を加えた長さの沿面距離を確保でき、したがって、上蓋２に薄肉の絶縁板２ａを用いて大きな絶縁耐力を確保することができる。本発明において、放熱体４は必ずしも筒状でなくてよい。重要な点は発熱ユニット３の発する熱を受熱して被加熱物を加熱又は加温することである。放熱体４が平坦な受熱面４ａと、クリップ６との組合せで形成されたときには、受熱面上にマット状の被加熱物を設置してこれを加熱又は加温することができる。   Further, since the flange 2b that fits within the opening edge of the case 1 is provided on the peripheral edge of the lower surface of the upper lid 2, the thickness between the heat generating unit 3 and the heat receiving surface 4a of the radiator 4 is set to the thickness of the insulating plate 2a of the upper lid. The creeping distance of a length that is twice the rising height inside the flange edge 2b can be secured, and therefore a large dielectric strength can be secured by using the thin insulating plate 2a for the upper lid 2. In the present invention, the radiator 4 is not necessarily cylindrical. The important point is to receive heat generated by the heat generating unit 3 to heat or heat the object to be heated. When the radiator 4 is formed by a combination of the flat heat receiving surface 4a and the clip 6, a mat-like object to be heated can be installed on the heat receiving surface and heated or heated.

さらに、本発明においては、ケース１の開口縁に嵌合してケース１を施蓋する上蓋２によって、発熱ユニット３と、放熱体４間の電気的な絶縁を確保するようにしたため、ケース１内に発熱ユニット３を組み込む際には、ばね端子１０、発熱素子９、平端子１１の順でケース１内に順次差し込み、最後に上蓋２をケース１内に圧入するだけの単純作業でよく、発熱ユニット３をケース１内に収納したのち、そのケース１に放熱体４を結合することによって発熱装置を構成できるため、発熱装置の組立作業の自動化もさることながら簡単な工具を用いて手作業による組み立てが可能となる。   Furthermore, in the present invention, the upper lid 2 that fits the opening edge of the case 1 and covers the case 1 ensures electrical insulation between the heat generating unit 3 and the radiator 4. When assembling the heat generating unit 3, the spring terminal 10, the heat generating element 9, and the flat terminal 11 are sequentially inserted into the case 1 and finally the upper lid 2 is press-fitted into the case 1 as a simple operation. Since the heat generating unit 3 can be configured by housing the heat generating unit 3 in the case 1 and then connecting the heat radiating body 4 to the case 1, manual operation using a simple tool can be achieved while automating the heat generating device assembly. Can be assembled.

発熱ユニットと放熱体とを電気的に隔離する絶縁手段をケースの上蓋として構成することによって、構成部品を発熱ユニットを収めたケースと、放熱体との２つの部品に単純化することができる。また、放熱体を筒状又は板状に加工して各種蒸散液の吸液芯だけでなく、マット式液体蒸散器用発熱装置に適用することができる。   By configuring the insulating means that electrically isolates the heat generating unit and the heat radiating member as the upper cover of the case, the components can be simplified into two parts, a case containing the heat generating unit and a heat radiating member. Further, the heat radiator can be processed into a cylindrical shape or a plate shape, and can be applied not only to the liquid absorption core of various transpiration liquids but also to a heating device for a mat type liquid transpiration device.
