Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to cooling oil supplied to machine tools, oil tuners for cooling cutting oil, or cooling water for supplying cooling water to water-cooled electronic equipment. The present invention relates to the configuration of a liquid temperature adjustment device applied to a supply device, etc.

[Conventional technology]

First, the configuration of a conventional liquid temperature adjustment device is shown in FIGS. 3 and 4. In the figure, ■ is the case, 2 is the compressor 3. Condenser 4. A refrigerator consisting of a cooler 5, 6 a heater unit, 7 a liquid pump, and 8 the cooler 5. A liquid supply pipe line is piped into the machine via a heater unit 6 and a liquid supply pump 7, 9 is a blower fan that flows cooling air to the condenser 4 (air-cooled type), and 10 is a control box, which adjusts the liquid temperature. configuring the device.

Here, the cooler 5 of the refrigerator 2 has a spiral evaporator coil 5b inside a double-structured cylindrical container 5a surrounded by an inner cylinder and an outer cylinder, as shown in FIG. 2 in detail. It is built-in, and there are liquid supply pipes 8 at the top and bottom of the cylindrical container 5a.
is connected. Further, the heater unit 6 has an electric sheathed heater 6b built inside a cylindrical container 6a, and the cylindrical container 6a is connected to the liquid feeding pipe line 8. Note that 11 is a pipe joint inserted into the liquid sending pipe line 9.

Such a liquid temperature regulating device is used in the following manner. That is, an external liquid sending pipe 12 is piped between the inlet and outlet of the liquid sending pipe 8 drawn out from the case 1 and a heat load such as a machine tool or an electronic device (not shown), and the liquid is supplied thereto. Circulating flow is used to cool the heat load to maintain it at the proper operating temperature. During this circulating flow process, the liquid that has returned from the heat load side (normally, the liquid temperature has increased by taking heat from the heat load) is transferred to the cooler 5 described above. After being cooled or heated as necessary during the flow process through the heater unit 6 and adjusted to a predetermined temperature, it is sent out again to the heat load.

[Problem to be solved by the invention]

By the way, the conventional configuration described above has the following drawbacks in terms of structure and handling.

(1) Since the cooler and heater unit of the refrigerator are separated and built into the case, they require a large space and the device becomes large.

(2) In a cooler with a double structure of inner and outer cylinders, the empty space in the center of the container is not used at all, and this becomes dead space, reducing space efficiency.

(3) Even when the heater unit is handled as an optional component, since the heater unit is installed at a distance from the cooler, piping work connecting the two is troublesome.

The present invention has been developed in consideration of the above points, and it is possible to improve space efficiency and make the entire device small and compact.In addition, when the heater unit is treated as an optional component, assembly and piping can be easily performed. An object of the present invention is to provide a liquid temperature regulating device.

Means for Solving Problem C] In order to solve the above problem, in the apparatus of the present invention,
The cooler and heater unit of the refrigerator shall be assembled together.

Here, as the above-mentioned integral assembly structure, for a cooler in which an evaporator coil is built in a cylindrical container with a double structure of inner and outer cylinders, a heater unit is removably housed in the central space of the cylindrical container. and the heater unit shall be assembled together.

In addition, in order to facilitate the handling of the heater unit in particular,
Inlet for liquid drawn from the heater unit.

It is preferable to attach a pipe joint to the outlet pipe and connect it to the liquid supply pipe inside the machine via this pipe joint.

[Effect]

According to the above configuration, since the cooler and the heater unit are assembled together, the occupied space can be reduced. Moreover, the piping path of the liquid feeding pipe connecting between the cooler and the heater unit is shortened, and the heater unit can be easily handled as an optional component by inserting a removable pipe joint into this portion. Furthermore, by inserting the heater unit into the inner space of the cooler with a dual structure of inner and outer cylinders and assembling it as one piece, there is no dead space in the cooler, which increases space efficiency accordingly.

〔Example〕

1 and 2 show an embodiment of the present invention. In the drawings of the embodiment, the same parts corresponding to FIGS. 3 and 4 are given the same reference numerals.

The basic configuration in FIG. 1 is the same as that in FIG. 3, but the main difference from the configuration in FIG. 3 is that the heater unit 6 is assembled integrally with the cooler 5 of the refrigerator 2. be. Specifically showing this assembly structure, as shown in FIG. 2, the heater unit 6 is attached to the cylindrical container 5a of the cooler 5, which has a dual structure of inner and outer cylinders, so as to fit inside the central space of the container 5a. Furthermore, the inlet and outlet pipes drawn out from the bottom of the cylindrical container 6a of the heater unit 6 are connected to the other pipe via a pipe joint 11 that can be attached and detached with one-touch operation. In addition, a partition plate 6C is provided in the container of the heater unit 6 between the outlet and the outlet side in order to improve heat exchange efficiency between the heater 6b and the liquid.

If the heater unit 6 is to be installed later as an optional component, the work procedure is to first insert the heater unit 6 into the central space of the container 5a from above and fix it, and then to install the heater unit 6 into the container 5a of the cooler 5 from above. The inlet and outlet pipes pulled out from the bottom are connected to the liquid feeding pipe line 8 via the pipe joint 11.

〔Effect of the invention〕

Since the liquid temperature adjusting device of the present invention is configured as described above, it exhibits an excellent effect.

In the structure of claim I, since the cooler and heater unit of the refrigerator are assembled together, the entire device can be made compact, and the length of the liquid supply pipe connecting between the cooler and the heater unit can be reduced. The length is short, and piping work can be done easily.

Further, by adopting the configuration of claim 2, the inner space of the cooler can be effectively utilized, thereby further promoting miniaturization and compactness of the device.

Furthermore, by employing the configuration of claim 3, assembly and piping of the heater unit can be easily performed, and handling especially when the heater unit is an optional component is facilitated.
