Description

Bonding method of heater and its structure {ASSEMBLING METHOD OF HEATER AND ASSEMBLY THEREOF}

The present invention relates to a coupling method of a heater and a structure thereof, and particularly, is applied to a gas heater, and the combination can modularize each unit in advance so that assembly can be performed quickly in a subsequent bonding process, and manufacturing energy can be saved. It is to ensure that.

h The air heater driven by the fan generally has an external shape in the form of a plate, and is configured by connecting a heat generating unit and a heat radiating unit. The connection method is to press the mechanical parts or to combine the bonding method, the assembly parts, referring to Figure 1, the heater 10 is coupled to the electrode plate 11 on both sides of the heating element (1), the electrode plate When electric power is conducted through the heat generating part 1 through 11, heat energy generated from the heat generating part 1 is indirectly dissipated toward the heat dissipation substrate 12 through the electrode plate 11, and the heat dissipation substrate 1. (12) achieves the purpose of air heating by heat exchange with the air passing through convection.

In the conventional bonding assembly method, referring to FIG. 2, a cover 14 is installed above the work table 16, and a heat drying apparatus 15 is installed inside the cover 14 to form a drying environment space 140. The components 16 such as the heat generating member 1, the electrode plate 11, and the heat radiating substrate 12 are arranged on the upper surface of the work surface 16 opposite the drying environment space 140. They are arranged in order according to their relationship. The joining operation applies an adhesive agent to each joining surface, and presses it by the fixed pressure p using the jig 13 of both sides. During the pressing process, the heat drying apparatus 15 emits heat radiation wave R to dry the adhesive, which is introduced into the center of each part in order from the outer surface. This approach has the following drawbacks.

1. When introduced into the part center from the outside during the drying process, its transfer time is long and the solidification state is not uniform.

2. If the component members are loosely arranged and the line of force is biased to one side at a fixed pressure p, there is a fear that the construction accuracy is lost.

3. When the part is loose and the holding pressure is too high, the part can be deformed thereby.

4. After the joining is completed, if the heating element has a defect, the adhesive is already solidified and can not be replaced, so the whole is thrown away, which can lead to waste of materials.

5. During the coagulation process, the heat dryer must radiate heat radiation, resulting in the energy consumption of the assembly process.

6. Since the jig and drying space are large spaces and the jig must have rigidity, metal materials are generally used, because they have considerable enthalpy, and the heat content can absorb heat radiation waves. As a result, the energy burden on the heat dryer is increased.

7. Jig has heat content effect and absorbs heat radiation wave, so it's easy to get your hands on during operation.

8. Although the cover is insulated, it cannot be completely insulated and heat radiation is transmitted to the outside. When the cover is opened, the heat energy inside the drying space is dissipated to the production line along the Brownian movement of the air. It can cause heat pollution, especially in summer.

9. The heat dissipation substrate and the electrode plate are made of metal, which can have a thermal expansion and cold shrinkage effect against heat, and thus can be expanded by heat during the bonding process and shrink when cooled, as well as a time for receiving heat. Because of the long deformation, the deformation may be large and the position shift due to shrinkage after cooling may be relatively increased, and the molecules of the adhesive may be easily torn during the process, thereby losing the bonding fixation force on the bonding surface.

SUMMARY OF THE INVENTION An object of the present invention is to provide a bonding method applied to an air heater and a structure thereof, in which each main body unit constituting the heater is separated first, and the unit is a heat exchange unit and a heat generating unit, and after bonding, a relatively high bonding force is achieved. It is possible to make the assembly production quickly, and conduct the energization test at the same time during the bonding process, and use the heat energy generated in the energization test process as the promoting energy of the adhesive solidification reaction, thereby wasting the energy of the conventional drying process. It is also to prevent the production of splicing and to make the splicing production quick.

The second object of the present invention is to mount the heat exchange module to one end of the energizing electrode, to insulate the heat dissipation board by fixing the insulating jig, and to obtain the buffering effect of the mechanical force when plugging or unplugging the terminal. It is to help physical action such as to endure pressure through intervention.

The third object of the present invention is to electrically couple with the absence of other use environments, such as after each unit is combined, to cover the entire outer surface of the heater with an insulating protective film to withstand physical or chemical properties, or to be applied to a vehicle. By isolating, it has a current blocking effect on other neighboring parts in the vehicle.

The fourth object of the present invention is to conduct an energization test simultaneously with the joining process, thereby using the exothermic energy to the heat generating unit, to transfer the heat of the conduction test directly to the bonding interface, and also to the bonding surface state. The bonding state of the area of the bonding unit is to be constant.

The fifth object of the present invention is to join each component in a joining manner, and to undergo a conduction test, before the adhesive is still solidified in the conduction test process, if there are components with poor electrical properties, the defective part before solidification By eliminating this, it is possible to prevent waste of materials and process time.

A sixth object of the present invention is to insert a heat conductive insulating plate into a heat exchange unit to cut off a current on a heat radiating substrate, and the insulating plate uses a mineral material such as aluminum oxide having high mechanical strength.

The seventh object of the present invention is to respond quickly to the demand of the market by selecting the quantity differently according to the change of quantity of each unit so as to quickly respond to the different power production, and to the parts safety and the stock of the production line. To prevent concerns.

The eighth object of the present invention is to reduce the cost of the jig or heat shielding material to prevent heat loss because the pressing jig does not need to use a high temperature resistant material during the manufacturing process.

The ninth object of the present invention is to significantly reduce the assembly work space of the production line through the practice of the present invention.

The tenth object of the present invention is to completely eliminate the use of heat-dry energy during the assembly production process, and also not to daisy-chain hands, and to allow the operating space to be freely moved.

The object of the present invention described above is to manufacture one or more plate-type heat generating units and two or more heat exchange units in a combination method of a heater, in particular, a method capable of rapidly combining the main component units independently produced by modularization with a heater, Coupling electrode plates to the heat exchange units, respectively; Applying an adhesive to the surface of the facing surface of each unit; Inserting and installing a heat generating unit according to an electrical arrangement in the heat exchange unit, and placing the heat generating unit in a flat surface on a workbench in an open space, and assembling it into a novice form of a heat generating unit; Pressing both sides of the heat generating unit with a jig to fix the outside; Simultaneously conducting an energization test of the steps to extract electrical parameters; Bonding the adhesive using the thermal action of the energization test; And extracting the finished product after coagulation of the adhesive.

According to the present invention, not only can be easily assembled on a workbench of a general production line, but also eliminates the burden of other heat-drying energy in the joining process, does not require the use of a cover facility, and there is a fear of having a worker's body in the operation process. No heat source is generated. In addition, since the operating space is open, it does not interfere with the assembly of the body, and conducts an energization test simultaneously during the joint solidification process, so that effective parameters can be obtained, and the heat wave generated by the energization test promotes an adhesive solidification process. It can play a role, shortening the joint solidification time and improving the production rate. The solidification state of the adhesive is uniform for the area of each unit of the mating surface, and the bonding firmness is evenly enhanced. In addition, the pre-configured units independently form the individual, can withstand the pressure of the jig in the process of combining with the heating unit, the conduction, heat transfer interface is more closely coupled, and each unit is standardized production method Independent bulk pre-production can eliminate component inventory concerns. Having the advantage of being able to carry out various types of production, it should be noted that equivalent implementations relating to the methods and structures of the invention should be included within the scope of the invention.

In the embodiment of the present invention, referring to FIG. 3, a unit constituting the heater 10 is first manufactured as a heat generating unit 2 and a paired heat exchange unit 3, and an electrode plate is provided in the heat exchange unit 3, respectively. 31 is provided and the terminal 4 is provided in one end. The heat exchange unit 3 performs heat exchange of air using the substrate 32, and the outer circumference thereof is fixed to the frame 33. The heat generating unit 2 is a plate-type heat generating member 21, the heat generating member 21 may use a positive temperature coefficient ceramic resistance heating element, a plurality of heat generating unit (2) type connected in series in the plate shape May be used.

Referring to Figure 4, the heater 10 of the present invention is configured by independently bonding the heat generating unit 2 and the heat exchange unit 3 completed in advance, the heat exchange unit 3 and the heat generating unit 2 is combined The surface is coated with an adhesive in advance, and both sides are pressed and fixed by a fixed pressure P generated by a jig (not shown). Since the heat exchange unit 3 and the heat generating unit 2 are manufactured in advance, In this case, the position between each part is already set first and thus combines mechanical force. Therefore, it can be pressed under a relatively high fixed pressure P, the contact surface of the heat exchange unit 3 and the heat generating unit 2 can counter the relatively high fixed pressure, and also by pressing the applied adhesive (not shown) It can be pressed and applied relatively firmly.

By conducting an energization test by introducing electric power from the terminal 4 at the same time during the crimping process, it is possible to detect whether the heat transfer operation is normal and at the same time extract the test parameters. If a defect occurs in the heat generating unit 2, the heat exchange unit 3 is quickly removed and the heat generating unit 2 is removed and replaced before the adhesive is still solidified, or in the process of applying a fixed pressure P, When the unit 3 loses mechanical resistance and is torn down, the heat exchange unit can be replaced. Such immediate replacement is a situation before the adhesive solidifies, so that sufficient collection and use of resources is possible.

During the conduction test process, if a heat wave is generated in the heat generating unit 2, it directly acts on the adhesive on the bonding surface of each unit to thermally accelerate the solidification of the adhesive. Therefore, the energization test carried out simultaneously in the present invention can immediately detect the normality of the parts, and secondly, the detected thermal energy can be directly used for solidifying and promoting the adhesive, and the heat is applied to the contact surface of each unit. Since it occurs evenly, the solidified state of the adhesive appears uniformly in the area of each unit. Since the jig does not need to be subjected to heat and only mechanical pressure is applied, the jig does not need to use a high temperature resistant material, and even a heat insulating material is used to absorb heat during the heating unit 2 and the energization test process. Can be prevented from being consumed.

According to the present invention, the assembly line can be executed anywhere in the production line having a flat table, and there is no need for a special dry manufacturing environment, and the assembly operation is not limited to space. After the heat exchange unit 3 and the heat generating unit 2 are assembled, one heat generating unit 100 is formed. According to the present invention, according to the demand of a single unit of heat generating unit 100, a plurality of heat exchange units 3 and a pair of heat generating units 2 are selected and combined in a parallel arrangement or a superimposed manner, thereby providing a heater 10 In response to the increase in the quantity of the heat generating unit 2 can be made to change the thermal work power. Therefore, it is possible to produce quickly in response to the demand of different power.

In the energization test process, since the heat generating unit 2 generates heat at the same time as a whole, the bonding interface is simultaneously heated. This eliminates the need for thermal equilibrium time and allows it to solidify quickly, resulting in a relatively fast production rate.

The heat exchange unit 3 uses the heat dissipation substrate 32 as a working body, and fixes the outer circumference of the heat dissipation substrate 32 with the mold 33. The coupling between the heat dissipation substrate 32 and the mold 33 may be combined by a tin plating method or a bonding method, and the bonding method may use an adhesive which solidifies at room temperature, and has heat conduction conditions after completion. .

The thermal energy generated during the energization test may promote the solidification rate of the adhesive to be bonded. If the adhesive requires a large amount of thermal energy promotion, the thermal energy may be extended to promote the solidification of the adhesive with a relatively large amount of thermal energy. It is possible to obtain an effect.

The outer circumference thereof is fixed by the frame 22. The frame 22 is made of a physical material, and has a receiving groove 220 to fit the heat generating member 22 therein. The heating member 21 may be fitted into the insertion groove 220 by using a dry coupling method or by applying an adhesive to the fitting interface so that the adhesive is solidified and coupled. The use of the frame 22 is carried out when there are a plurality of heat generating members 21, and the frame 22 is regularly combined to form a single plate-shaped heat generating unit 2.

Referring to FIG. 6, a gap between the electrode plate 31 and the heat dissipation substrate 32 of the heat exchange unit 3 may be spaced by a heat conductive insulating plate 5, and the heat conductive insulating plate 5 may be an electrode plate 31. Because it isolates the heat dissipation substrate 32 is thereby disconnected from the electricity. The outer circumference of the heat dissipation substrate 32 is fixed by the mold 33, and the mold 33 and the insulating plate 5 and the electrode plate 31 are similarly bonded by a joint solidification method, but are coupled at room temperature or in other ways. Basically, it must be completed first so that the insulating plate 5 can be sandwiched between the electrode plate 31 and the heat dissipation substrate 32 or the installed frame 33.

Referring to FIG. 7, the heat exchange unit 3 is configured by coupling the heat dissipation substrate 32 and the mold 33 to the electrode plate 31 via the heat conductive insulation plate 5.

Terminal 4 is a form exposed to the outside, basically there must be a fixed thing, and should be arranged at intervals according to the position of the plug. The refraction portion 310 is provided at one end of the electrode plate 31, and the refraction portion 310 is formed by the refraction surface 311. In the present invention, the terminal 4 independent of the refraction surface 311 is further provided. Indirectly connected.

Therefore, the terminal 4 is fastened by the fastening groove 61, and only one side is fixed, and the other side is connected to the lower part of the insulating plate 5 via the electrode plate 31 extending from the refraction portion 310, thereby fixing two points. In addition, since the insulation fitting 6 has a rectangular shape and is fixed in another axial direction, the terminal 4 is fixed three-dimensionally. That is, the heat dissipation substrate 32 or the frame 33 is disconnected from the current by using the space between the insulation fittings 6, and the mechanical buffering force is provided to the terminal 4 in the process of turning on and off the power supply.
