Problems solved by technology

[0009] However, in the floor heating equipment systems of Patent Documents 1 and 2, the pipes, hot water pads, or floor materials through which hot water passes are separate components, and the cost of integrating them is quite high, and the pipes, hot water pads, or floor materials The material is not completely assembled tightly, so there is a problem of low heat conduction efficiency
[0010] In addition, the thermal insulation toilet seat of Patent Document 3 is a component composed of two resin molded parts, the toilet cover and the base plate, and a planar heating element. The assembly cost is high, and the gap between the heating element and the cover cannot be avoided. There are voids and the thermal efficiency is low
[0011] In addition, with regard to automobile hoods, housings of home appliances, and office automation equipment, it is not enough to provide a heat dissipation function at the material level or design level as described above, and it is still a subject of research.

Embodiment 1

[0049] use as figure 2 The mold shown in the figure is integrally molded with an injection molding machine ("TP-180H" manufactured by Toyo Ki Metal Co., Ltd.) figure 1 Resin molded products with the following dimensions shown.

[0050] tube

[0051] Outer diameter 7mm, inner diameter 4.5mm, wall thickness 1.25mm, length 200mm

[0052] flat part

[0053] 100mm×150mm, wall thickness 1.5mm

[0054] A steel ball with a diameter of 4.5 mm was used as a floating core, and a pressurized fluid was supplied from a gas generator for gas hollow injection molding ("airmold" manufactured by Asahi Engineering Engineering Co., Ltd.). Nitrogen was used as the pressurized fluid. As the resin, a polyamide 66 resin ("Leona 1300G" manufactured by Asahi Kasei Co., Ltd.) containing 33% by weight of glass fibers was used.

[0055] First, if image 3 Shown, with resin temperature 260°C, injection pressure 11.77MPa (120kg / cm 2 ) conditions to inject the above resin, the injection pressure...

Embodiment 2

[0059] A molded article was obtained under the same conditions as in Example 1 except that PPS resin (Toray; TORAY high thermal conductivity material HS01) was used as the resin and the resin temperature was 320°C.

[0060] When 5° C. cold water was passed through one end of the pipe portion of the obtained molded product and discharged from the other end, the average temperature of the flat plate portion was 18° C., showing sufficient performance as a heat dissipation unit.

Abstract

Disclosed is a low-cost resin molding, which can give heat-insulating and heat-radiating functions of extremely excellent heat transfer and which has high reliability and a convenient manufacturing process. The resin molding is integrally injection-molded to comprise a pipe (1) which has at least a bent pipe portion (3) and passes a fluid, and a flat plate (4).

Description

technical field [0001] The present invention relates to a resin molded body in which a pipe portion and a flat plate portion are integrally injection-molded and a method for producing the same. More specifically, it relates to a resin molded body that functions as a thermal insulation board or heat sink by passing a fluid through the pipe portion and a method for manufacturing the same. . Background technique [0002] Conventionally, in a floor heating system having a thermal insulation function, as shown in Patent Documents 1 and 2, for example, a pipe for flowing hot water, a hot water pad incorporating the pipe, and a composite of floor materials are generally used. [0003] In addition, regarding the warm water toilet seat, Patent Document 3 describes an example in which a heating wire for heat preservation is incorporated in the space between a cover plate and a base plate made of a resin molded body to impart a heat preservation function to the toilet seat. [0004] F...
