Abstract

PURPOSE:To keep a woody nature and enable a member to be used as a thermal radiating member in a floor heating process by a method wherein the wooden material having a degree of driness with a rate of moisture less than a specified value and provided with some through-pass holes therein is applied, a thermal medium flowing preventive processing is applied to the through-pass holes, the thermal medium is circulated within the through-pass holes and then heat is radiated through the wooden material. CONSTITUTION:A core part 2 of a wooden material 1 is formed with a through-pass hole 3 having an inner diameter of 3cm. A water-proof (liquid) processing is applied in the through-pass hole 3. In this case, a thermal medium flowing pipe 4 is fitted so as to have the above-mentioned waterproof process. As the wooden material 1, material having a rate of moisture less than 15% (preferably, a rate of moisture or about 10% or less) as its degree of driness is applied. This is applied because a feature of the wooden material is realized under a more preferable condition. Normally, in order to dry a woody material up to a rate of moisture of about 10%, its drying period is extended and its drying facility is large in scale. However, a presence of the through-pass hole 3 enables an easy drying to be performed and further the through-pass hole 3 may act as a thermal radiator.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a heat radiator that retains the properties of wood and a method for manufacturing the same, and more specifically relates to a heat radiator that retains the properties of wood and a method for manufacturing the same. The present invention relates to a heat dissipating body that maintains the properties of the present invention and a method for manufacturing the same.

[Technical background of the invention]

Conventionally, various heat radiators have been known, and typical examples include electric carpets, electric blankets, and panels with built-in infrared radiation sources. but,
These heat radiators have problems such as the cost of supplying heat sources being too high.

Further, all of these heating elements are configured to be used indoors by being laid on the floor. Therefore, although the floor surface has the advantage of being able to move freely,
For example, in the case of a floor made of wood, there are problems such as the hygroscopicity, moisture release, warmth, etc. of the wood being impaired.

By the way, in recent years, dried wood materials have been reconsidered as wall materials for buildings and the like. This is due to the fact that dry wood is ``breathing'' and adapts to its natural environment, although this may be due to its design and color tone.

Therefore, the present inventor conducted various studies based on the viewpoint of whether it was possible to obtain a heat dissipating body that could be obtained without impairing the characteristics of wood materials, and as a result, learned the following. In other words, ■ Ordinary lumber must be dried to a certain degree (moisture content of 15% or less) in order to be used as a building material, so if it is left outdoors for several years and once it has dried to a certain extent, it should be dried. I put it in the oven to dry it.

■ ■It takes a lot of time to achieve the desired degree of dryness.

■ If normal drying methods are used, cracks may occur on the surface.

■ In many cases, the drying oven uses an internal heating device such as microwave heating, so it is necessary to take measures such as electromagnetic shielding.

Next, the present inventor further addressed the above-mentioned problems, and based on the viewpoints of (1) how much dryness should be set, and (2) how to provide heat medium flow passages, various As a result of consideration, we found the following.

■ After making a through hole in the lumber, hot air containing steam is applied to the lumber from two directions: the outside of the lumber and the inside of the through hole, resulting in a structure that is free from cracks, has sufficient strength, and has a moisture content of 15%.
Dry timber with the following dryness is obtained:

(2) The above-mentioned dried lumber is provided with through holes, which can be used as heat medium flow paths and have the strength as a building material.

- Dry lumber with a moisture content of about 15% allows for natural temperature regulation and there is no risk of condensation.

The present invention was devised in response to the above points, and its purpose is to maintain the properties of wood and to maintain the properties of wood that can be used as a heat dissipation member in floor heating etc. An object of the present invention is to provide a heat sink and a method for manufacturing the same.

[Means to achieve the purpose]

As a means for achieving the above object, the heat dissipating body retaining the properties of timber of the present invention uses a dry wood with a moisture content of 15% or less and is provided with through holes. The structure is such that the through hole is treated to prevent the heat medium from flowing out by fitting a waterproof pipe, etc., and the heat medium is circulated within the through hole to radiate heat through the wood material.

Here, in the above structure, the wooden material is usually constructed from tatami mats, or square timbers or panels such as cedar or cypress wood. In addition, if necessary, multiple wooden materials can be connected and arranged so that the respective flow paths are properly connected to form a single panel to form a building floor or a soil heating bed for a greenhouse. The configuration is as follows.

In addition, the method for manufacturing a heat radiator that maintains the properties of timber according to the present invention as a means for achieving the above-mentioned object is such that after drilling a through hole in the core of the timber, the front side of the timber and the inside of the through hole are Apply hot air containing steam from both sides to reduce the moisture content to 15
% or less, and then perform heat medium outflow prevention treatment by fitting a waterproof vibrator into the through hole, etc., and flow the heat medium through the treated through hole to transfer the heat of the heat medium through the wood material. The structure is such that heat can be radiated by

In this specification, the term "r heating medium" is a concept that also includes the refrigerant J that radiates r cold air. Therefore, in this case,
In other words, the "heat radiator" can also be called a "cooler radiator."

[Effect]

The heat dissipating body of the present invention based on the above structure retaining the properties of lumber allows the heat medium to flow through the waterproofed through holes, thereby preventing the heat medium in the through holes from passing through the surrounding wood material. It acts to radiate heat. In this case, the wood has been dried to a moisture content of 15% or less (preferably 10% or less), which increases the heat radiation efficiency and naturally adjusts the humidity in the atmosphere where it is installed. It works like this. Therefore, even if the inside of the wood material is heated by a heating medium, it acts to prevent cracks and the like from occurring.

Further, according to the method for manufacturing a heat radiator that maintains the properties of lumber according to the present invention based on the above structure, the through holes drilled in the drying process for drying the heat medium flow passage to a moisture content of 15% or less are utilized. It has the effect of being able to be formed by

As described above, the heat dissipating body of the present invention that maintains the properties of timber uses wood material that has been dried to a moisture content of 0.15% or less. It has two characteristics: the distribution of the medium, and these characteristics improve the properties of wood, such as workability, adhesiveness, moisture permeability,
It is possible to provide a heat dissipating body that has properties as a heat dissipation source without losing its moisture dissipation properties. Furthermore, the method for manufacturing a heat radiator that maintains the properties of lumber according to the present invention is characterized in that the drying through-hole is used as a heat medium flow path, and this characteristic point allows the through-hole to be used effectively. This is the method I used.

〔Example〕

Hereinafter, embodiments embodying the present invention will be described with reference to the drawings.

Here, Figs. 1 to 3 show embodiments of the present invention, Fig. 1 is a perspective view of a heat radiator, Fig. 2 is a longitudinal cross-sectional view of the heat radiator, and Fig. 3 is a manufacturing process for manufacturing the heat radiator. It is a process diagram.

The heat sink of this example is made of wood material 1 as shown in Fig. 1.2.
It is made of square timber. Here, as the wood material 1, a square lumber made of cedar wood or seed material of 9asX 9aIX 4000 is usually used. However, it is clear that other types, shapes and sizes may be used.

A through hole 3 having an inner diameter of 3 cm is bored in the core portion 2 of the wooden material 1, and the through hole 3 is treated with waterproofing (liquid). Here, the heat medium flow pipe 4 is fitted and the treatment has been performed. Further, the number of through holes 3 is not limited to one, but may be configured to include a plurality of through holes.

Note that the wood material l has a moisture content of 15% or less (preferably 1
The dryness level (moisture content of about 0% or less) is used. This is the most important point in completing the heat dissipation body of the present invention, and by using the wood material 1 with this moisture content, the characteristics of the "r wood material" itself can be exhibited in a favorable state. 0 Normally, as mentioned above, drying lumber to a moisture content of about 10% requires a long drying period and requires large-scale drying equipment, but the presence of the through holes 3 , easy drying is possible, and the through holes 3 can act as heat radiators.

By the way, the heat sink l as described above is manufactured in the following manner. That is, as shown in FIG. 3, the manufacturing process involves three steps: 0 through-hole drilling process, 1) drying process, and 2 heat medium flow path forming process.

Consistent hole drilling process 1 This step is a step of drilling a through hole in the core of the lumber.

That is, it is a process of drilling one or more through holes in the core of the timber using a boring machine or the like.As the timber, various materials may be used, including interior materials such as cedar and cypress, as well as exterior materials. Sometimes used. Furthermore, if necessary, the thinned wood 1 may be used as square lumber or round lumber in order to effectively utilize the thinned lumber 1. Furthermore, plate-shaped timber or the like may be used.

The size of the through hole is 173 mm, which is the outer diameter of the lumber.
The hole has an inner diameter of approximately This is based on consideration of the strength after drying, but it is not limited to sizes with other ratios, round holes, for example, square holes, etc. In case, U
It may also be a through hole in the shape of a letter or an elbow shape.

One drying process The one drying process is a process for drying the lumber in which through holes have been drilled to a moisture content of 15% or less.

In order to dry the wood to a moisture content of 15% or less, hot air is applied to the front side of the lumber, and hot air is sent from inside the through hole to dry both the inside and outside. Here, hot air having a temperature of around 100° C. and a humidity slightly lower than the moisture content of wood is used. Further, the moisture is reduced depending on the dryness of the timber.

However, the configuration is not limited to this.

Through drying work, when the dryness of the lumber reaches a predetermined value, the strength is improved to about 1.5 times that of undried lumber without through holes, and the strength is improved by about 1.5 times, and there is no cracking or deflection. It was confirmed that j did not occur either.

One heat medium flow path forming step The first step is a step in which the through holes of the dry wood material obtained in the previous step are formed as heat medium flow paths. That is, this is a process of performing waterproofing to prevent leakage caused by flowing steam or hot water (liquid) into the through hole. In addition,
When hot air is passed as a heat medium, hot air outflow prevention processing is performed to prevent the hot air itself from directly flowing out to the outside of the wood material.

Here, it is formed by fitting a heat medium flow pipe into a through hole. The fitting is performed by inserting and integrating into the through hole. However, it may also be formed by coating the inside of the through hole with a resin.

A heat radiator is obtained by performing the steps described above, and a joint part (for supplying and discharging a heat medium) is provided at the end of the heat radiator.
fittings) are installed. Then, by connecting the heat radiators in parallel and in series, it becomes a panel shape (for example, a unit panel heat radiator made of the same size as a tatami mat), and a flooring material having a heat radiating part,
We are able to obtain wall materials, ceiling materials, soil heating beds for greenhouses, field board members, etc. It is important that the joints between the unit panels, the heat medium flow passages of the unit heat radiators, etc., connect the respective pipes, etc. in a watertight manner.

Next, in order to confirm the effect of the heat radiator obtained in the above example, 10 heat radiators (heat radiators made of square timbers with a length of 1800 m and a width of 90 m+) were connected to the recipient's size and made into panels. A unit panel heat radiator consisting of panels connected in the horizontal direction and jointed at the ends so that each heat medium flow path forms a single path, and formed to the size of the receiver) is laid on the tatami mat. The heat medium flow path was connected to form the floor of a 6 tatami room (room temperature = 10°C), and hot water at 45°C was circulated from the end of the heat radiator. When the surface temperature of the material was measured, heat radiation of around 22℃ was detected, and the center of the room was 18℃ and the ceiling was 18℃.
was detected. From this result, it was confirmed that the heat radiator of this example could be sufficiently used as a heating system such as floor heating.

Note that the present invention is not limited to the embodiments described above, and includes modifications that can be made within the scope of the invention. Incidentally, wood materials are not limited to lumber and tatami mats, but also include, for example, man-made building materials that have the characteristics of wood (panels obtained by mixing and compressing calcium silicate and glass fiber, etc.). You may use this.

By the way, when a plurality of panel-shaped unit panel heat radiators according to this embodiment are laid on a floor frame, the floor surface is slightly larger than the laid panels, in other words, the laid panels are made smaller than the floor frame. As a condition, each flow passage can be jointed, and after the joint is completed, another wooden material is used in the gap where there is usually no flow passage. ) etc. are preferably fitted. and,
In such a configuration (paneled), - it acts as a floor heating by supplying a heat medium such as hot water into the inside of the circulation path that communicates with the contract, and it can supply a heat medium such as cold liquid. It also functions as an air conditioner, and has the advantage that each unit panel heat radiator can be easily replaced with a tatami mat in the summer.

(Effects of the Invention) As is clear from the above description, according to the heat radiator of the present invention, by circulating the heat medium in the waterproofed through-hole, the heat medium in the through-hole is Heat is radiated through wood that has been dried to a moisture content of 15% or less (preferably 10% or less), which increases heat radiation efficiency and reduces humidity in the installed atmosphere. This has the effect of providing a radiator that retains the natural regulating characteristics of wood.

Furthermore, according to the method for manufacturing a heat radiator of the present invention, the heat medium flow passages can be formed using the through holes drilled in the drying process to dry the moisture content to 15% or less, so that the characteristics of wood can be maintained. This has the effect that a retained heat dissipating body can be obtained through a simple process.
