液体にて冷却するものである。 Conventionally, a heat exchanger disclosed in Japanese Utility Model Application Publication No. 58-181988 has been developed. As shown in FIG. 1, this heat exchanger includes a cooled pipe 5', which is a cooler 5 of an engine device 4 that drives the pump 1, in a short pipe 3 interposed in a discharge pipe 2 of a pump 1. The coolant whose temperature has increased through the engine device 4 is guided to the pipe 5' to be cooled, and is cooled by the liquid flowing inside the discharge pipe 2.
以下、第２図を参照して従来例を説明する。 A conventional example will be explained below with reference to FIG.

This conventional example has a configuration in which a cooler 13 is installed within a short pipe 10, and a branch guide 21 is provided on the upstream side thereof. This cooler 13 is a frame body 1
4 is fixed to the lid 12, and a cooled pipe 15 is wrapped around the frame 14.
このような従来例では冷却器１３に管路内を流
れる塵芥等の異物が引掛つたり、管路の流れ抵抗
が増大する不具合があつた。 In such a conventional example, there have been problems in that foreign matter such as dust flowing in the pipe line gets caught in the cooler 13, and flow resistance in the pipe line increases.
本考案は、このような事情に鑑みてなされたも

ことを目的とする。 The present invention was developed in view of these circumstances, and can prevent foreign matter such as dust from getting caught in the heat exchanger, reduce flow resistance, and further improve heat exchange. An object of the present invention is to provide an in-line heat exchanger that can improve efficiency.

るにあたり、前記冷却流体の流路に平行にかつ前
記開口よりも外周にさらには前記開口の底レベル
よりも上側のみに弧状に配設したものである。 In order to achieve the above object, the present invention is arranged at the discharge port of an engine-driven pump, and a cooled pipe is arranged inside a casing having openings at both ends, and the water discharged from the pump is introduced into the casing. In an in-line heat exchanger that passes cooling fluid, when arranging a plurality of cooled pipes inside the casing, the pipes are arranged parallel to the flow path of the cooling fluid, on the outer periphery of the opening, and further below the bottom level of the opening. It is also arranged in an arc shape only on the upper side.
前記被冷却管は冷却流体の流路に平行にかつ開

管に引掛ることが防止され、また被冷却管はケー
シングの開口間を流通する冷却流体の本流に近接
して配置されているので熱交換効率が向上する。 Since the cooled pipes are disposed parallel to the flow path of the cooling fluid and on the outer periphery of the openings, the flow resistance of the cooling fluid flowing between the openings of the casing is significantly reduced, and moreover, the dust contained in the cooling fluid is reduced. Since the foreign matter such as the like flows inside the cooled pipe, the foreign matter is prevented from getting caught in the cooled pipe, and the cooled pipe is arranged close to the main flow of the cooling fluid flowing between the openings of the casing. This improves heat exchange efficiency.

妨げられて性能が著しく低下するのである。 In addition, in the in-line heat exchanger of the present invention, the tubes to be cooled are arranged in an arc only on the outer periphery of the opening and above the bottom level of the opening, which effectively prevents corrosion of the tubes to be cooled. This has the advantage that it is possible to prevent the heat exchange from occurring, and also to efficiently provide heat exchange to all the cooled pipes arranged therein. That is,
If the cooled pipe is placed below the bottom level of the opening, sand, mud, dirt, pump discharge water, etc. will accumulate in that area, and the accumulated sand, mud, dirt, pump discharge water, etc. As a result, the pipe to be cooled corrodes and holes form, which can lead to serious problems.In addition, sand, mud, etc. adhere to the pipe to be cooled, which impedes heat exchange with the pump discharge water, resulting in a significant drop in performance. .

みに弧状に配設すれば、被冷却管の腐蝕、配設し

ることができるのである。 Therefore, if the pipe to be cooled is arranged in an arc shape only on the outer periphery of the opening and above the bottom level of the opening as in the present invention, corrosion of the pipe to be cooled and heat of the arranged pipe to be cooled can be avoided. This makes it possible to effectively prevent a decline in the exchange rate.

構成されている。 Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 3 to 5. Reference numeral 26 in FIG. 3 is a casing, which has openings 22 at both ends and a flange 20 formed in the opening. As shown in FIG. 4, the casing 26 has a larger cross-sectional area than the opening 22, and the center O1 of the cross-section of the casing 26 is aligned with the center of the opening 22. Further, the casing 26 is formed by abutting an upper body 28 and a lower body 30, and legs 32 are attached to the outer peripheral surface of the lower body 30. Furthermore, an inspection window 34 is provided in the axial center of the casing 26, one at the top and two at the bottom, so that the inside of the casing 26 can be inspected. A first plenum 36 is disposed at the right end of the casing 26, and a second plenum 38 is disposed at the left end. Both of these plenums 36, 38 are formed in the shape of an arc of a lower cavity around the outer periphery of the opening 22 with the center of the cross section O1 as the center, and have an internal space.
Further, both the plenums 36 and 38 are communicated with each other by cooled pipes 40 as shown in FIG.
are disposed along the circumference centered on the cross-sectional center O 1 and are not disposed below the opening 22 . In other words, the cooled pipe 40 is
It is arranged in an arc only above the bottom level of No. 2. The first plenum 36 is connected to an inlet 44 and an outlet 46 for water to be cooled, which is a fluid to be cooled. The first plenum 36 is divided into a plurality of sections by partition plates 48 arranged in the radial direction. Two cooled pipes 40 are connected to each compartment to which the inlet 44 and the outlet 46 are connected. In addition, each intermediate compartment has four cooled pipes 40.
is connected. The second plenum 38 is configured to connect four cooled pipes 40 to all compartments.

温となり熱交換が行なわれる。 The operation of the in-line heat exchanger having such a configuration will be explained. First, cooling water flows into the casing 26 from the left flange 20, for example, and flows out from the right flange 20. The cooled water cooled by the cooling water flows from the inlet 44 into the compartment at the right end of the first plenum 36 . Two cooled pipes 40 communicate with this compartment, and the cooled water passes through the two cooled pipes 40 to the second plenum 38.
flows into. Since the second plenum 38 communicates the four cooled pipes 40 with one compartment, the cooled water flowing into the compartment of the second plenum 38 from the two cooled pipes 40 at the right end flows into the adjacent compartment. It flows into the second compartment from the right end of the first plenum 36 through two cooled pipes 40 . In this way, the water to be cooled repeats meandering in the axial direction of the casing 26 and flows out from the outlet 46. Then, while flowing through the cooled pipe 40, the water to be cooled is cooled by the cooling fluid (pump discharge water) flowing in the casing 26, and becomes low temperature, thereby performing heat exchange.
以上の如き実施例では本考案の効果に加えて次

ケーシング２６は上下に２分割されるので保守
点検の際には上部体２８を取外して容易に内部の
保守点検を行なうことができる。 Since the casing 26 is divided into upper and lower halves, the upper body 28 can be removed for maintenance and inspection, and the interior can be easily inspected.
なお、本考案は以上の実施例に限定されるもの
ではない。たとえば、被冷却水は被冷却管４０を

通するようにしてもよい。 Note that the present invention is not limited to the above embodiments. For example, the water to be cooled is not limited to flowing through the to-be-cooled pipe 40 in a meandering manner, and may be made to flow only in one direction.
