Description
Technical Field
The present invention relates to a temperature-controlled air supply device.
Background
Conventionally, as disclosed in japanese patent laid-open publication No. 2009-530588, there is known a temperature-controlled air supply device including an air conditioning unit that adjusts the temperature of air, a pipe through which the air whose temperature has been adjusted in the air conditioning unit flows, and a cover that is connected to the pipe and forms a predetermined inspection area. In the temperature-controlled air supply device disclosed in japanese patent application laid-open No. 2009-530588, air whose temperature has been adjusted by the air conditioner is blown out through a pipe into a predetermined inspection area, and therefore the temperature of the inspection area or the temperature of a test piece placed in the inspection area is adjusted to a predetermined temperature.
Since the temperature-controlled air supply device disclosed in japanese patent application laid-open No. 2009-530588 is configured to blow air into the inspection area formed by the cover, the blowing noise when the air is blown into the cover is not much concerned. However, if the volume of the blown air needs to be increased, the sound may be intentionally blown out. In addition, when the structure is adopted in which the temperature-controlled air is blown to the predetermined inspection area without providing the cover, there is a possibility that the sound is blown out more intentionally.
Disclosure of Invention
The purpose of the present invention is to provide a temperature-controlled air supply device that can achieve such an unexpected level of air blowing sound when blowing temperature-controlled air toward a test object.
The temperature-controlled air supply device according to the present invention includes: a pipe into which air is introduced, and a heater provided at a distal end of the pipe. The heater includes a heating element configured to heat air and an outer case housing the heating element. The heating element functions as a stopper for air flowing in the outer case before being blown out from the heater.
According to the present invention, the blowing sound of the air when the temperature-adjusted air is blown out to the test object can be made inconsiderable.

Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
The temperature-controlled air supply device according to the present embodiment is used to adjust the temperature of a test piece or the temperature around the test piece to a predetermined temperature and blow the temperature-adjusted air toward the test piece. The test body may be a test object to be subjected to a material test by being set in, for example, a universal tester (tensile tester), an impact tester, a friction and abrasion tester, or the like. In addition, the test object may be a test object to be measured such as an output current value or an output voltage value, for example, in an electronic module.
As shown in fig. 1, the temperature-controlled air supply device 10 includes a device main body 14 having a cooling unit 25 capable of cooling air supplied to a test piece. The apparatus main body 14 includes, in addition to the cooling unit 25: an inlet pipe 16 for guiding air to the cooling unit 25; a delivery pipe 18 through which air having passed through the cooling unit 25 flows; and a control panel 20 for controlling the cooling unit 25, a heater 31, and the like, which will be described later.
An external supply source (not shown) is connected to the introduction pipe 16, and air is supplied from the external supply source to the introduction pipe 16. The air supplied from the external supply source is pressurized so as to be blown out to the test object.
As the cooling unit 25, for example, an evaporator of a refrigerator constituting a vapor compression refrigeration cycle is used. The air introduced into the introduction pipe 16 is cooled to a predetermined temperature in the cooling unit 25.
The delivery pipe 18 is provided with a flow rate control valve 28. The air having passed through the cooling unit 25 is adjusted in flow rate by the flow rate adjusting valve 28, and then is led out from the apparatus main body 14 through the lead-out pipe 18. The flow rate control valve 28 may be provided upstream of the cooling unit 25. Further, the flow rate adjustment valve 28 may be omitted.
The control panel 20 controls the cooling unit 25 and the heater 31 so that the temperature detected by a temperature detector 32 described later reaches a predetermined temperature. The control panel 20 controls the flow rate adjustment valve 28 so as to achieve a predetermined air flow rate. The flow rate control valve 28 may be formed of a manual valve instead of being controlled by the control panel 20.
A pipe 30 for circulating the air led out from the lead-out pipe 18 is connected to the lead-out pipe 18. The pipe 30 is made of a flexible material and can be flexibly bent. Since the pipe 30 is insulated, the temperature of the air in the pipe 30 is hard to change.
The pipe 30 is provided with a heater 31. The heater 31 is provided at the distal end of the pipe 30 and can heat the air flowing through the pipe 30. The air having passed through the heater 31 is blown out from the heater 31.
A temperature detector 32 is provided at a downstream end of the heater 31. The temperature detector 32 detects the temperature of air flowing around a heating element 34 (see fig. 2) described later of the heater 31, and outputs a signal indicating the detected temperature. This signal is sent to the control panel 20 of the apparatus main body 14.
As shown in fig. 2, the heater 31 includes a heating element 34 and an outer package 36 configured to house the heating element 34.
The outer package 36 includes a tubular pipe main body 36a made of metal and an electrically insulating inner pipe 36b fixed to the inner circumferential surface of the pipe main body 36a. The inner tube 36b is attached to the tube main body 36a at least in a region where the heating element 34 is arranged. In the case where the heating element 34 is covered with an electrically insulating coating layer to ensure electrical insulation between the tube main body 36a and the heating element 34, the inner tube 36b may be omitted and the outer covering 36 may be formed of a metal member. In the case where the tube main body 36a is formed of an insulating material, the inner tube 36b may be omitted.
The tube main body 36a (outer package 36) is formed in a shape extending in one direction. A space (internal space) S1 is present in the tube main body 36a (outer package 36), and the space (internal space) S1 is open at one end 36c and at the other end 36d in the longitudinal direction.
A first joint 38 is provided at one end 36c of the pipe main body 36a (outer package 36), and the pipe 30 is connected to the first joint 38. When the outer package 36 is connected to the pipe 30, the space inside the pipe 30 communicates with the internal space S1 of the outer package 36.
The other end 36d of the tube main body 36a (outer package 36) forms an air blowing portion by opening through the internal space S1.
A second joint 40 is provided at the other end 36d of the tube main body 36a (outer package 36) so as to be able to connect a blow-out pipe (not shown). That is, the opening of the other end 36d of the package 36 may be directed toward the test piece so that the air blown out from the opening is directly blown toward the test piece, but an unillustrated blow-out pipe may be connected to the second joint 40 so that the air blown out through the blow-out pipe is blown toward the test piece.
A temperature detector 32 is attached to the second joint 40. The temperature detector 32 detects the temperature of the air that passes through the heating element 34 and is blown out from the heater 31. The temperature detector 32 may be attached to the other end 36d of the tube main body 36a (the outer package 36) instead of the second joint 40. In this case, the temperature detector 32 also detects the temperature of the air after passing through the heating element 34.
The exterior body 36 is covered with a decorative plate 42, and a heat insulator 44 is provided in a space between the exterior body 36 and the decorative plate 42. In addition, the thermal insulation member 44 and the decorative plate 42 may be omitted.
An intermediate portion 36e between one end portion 36c and the other end portion 36d of the package body 36 has a larger diameter than the one end portion 36c and the other end portion 36d. That is, the inner diameter of the middle portion 36e of the outer package 36 is larger than the inner diameters of the one end portion 36c and the other end portion 36d. The intermediate portion 36e functions as a housing portion for housing the heating element 34. The inner tube 36b is provided on the inner peripheral surface of the intermediate portion 36e of the tube main body 36a. The inner diameter of the intermediate portion 36e may be the same as the inner diameters of the one end portion 36c and the other end portion 36d.
The heating element 34 is formed of a wire rod that generates heat by conduction, and is disposed so as to surround the core rod 46 formed of an insulator. That is, the heating element 34 is disposed in a space (accommodation space S2) defined by the intermediate portion 36e of the package 36 and the plug 46. The housing space S2 is a part of the internal space S1.
The heating element 34 is wound around the mandrel 46 and is disposed in a predetermined range of the direction in which the mandrel 46 extends. The temperature detector 32 is disposed at a position spaced a small distance downstream from the heating element 34. In addition, if the shape retention of the heating element 34 can be ensured even without the mandrel 46, the mandrel 46 may be omitted.
One lead wire 47 connected to one end of the heating element 34 is inserted into a through hole 46a formed in the center of the mandrel 46, and is pulled out from the base end of the mandrel 46 to the outside of the package 36. The other lead wire 48 connected to the other end of the heating element 34 is drawn out to the outside of the package 36 without being inserted through the through hole 46 a.
The cross-sectional area of the housing space S2 defined by the intermediate portion 36e of the exterior body 36 and the mandrel bar 46 in the direction perpendicular to the flow direction of the air (the direction in which the internal space S1 extends) is substantially the same as or smaller than the cross-sectional area of the space inside the pipe 30 in the direction perpendicular to the flow direction of the air. The heating element 34 is disposed in the housing space S2, and the heating element 34 occupies at least half (or 70% or more) of the cross-sectional area of the housing space S2 in the direction perpendicular to the flow direction of the air. Therefore, the cross-sectional area of the portion of the housing space S2 not occupied by the heating element 34 in the direction perpendicular to the flow direction of the air is considerably smaller than the cross-sectional area of the space inside the pipe 30 in the direction perpendicular to the flow direction of the air. Therefore, the heating element 34 functions as a resistor for the air flowing in the housing space S2.
The heating element 34 may be in contact with the inner surface of the outer case 36 or may be spaced apart from the inner surface of the outer case 36. However, the gap width between the heating element 34 and the inner surface of the package 36 is preferably extremely small. In this case, air may flow between the heating element 34 and the inner surface of the outer case 36. Therefore, the heating element 34 functions as a resistor for the air flowing in the housing space S2. Even when the heating element 34 is disposed so as not to contact the inner surface of the package 36, if the heating element 34 generates heat and expands, the heating element 34 may contact the package 36.
Further, the heating element 34 is not in close contact with the mandrel 46 but has a slight clearance from the mandrel 46, allowing displacement of the heating element 34 in the length direction of the mandrel 46. Therefore, when the air flows in the housing space S2, the air sometimes flows between the heating element 34 and the core rod 46. Therefore, the heating element 34 surrounds the mandrel 46 so as to allow air to flow between the heating element 34 and the mandrel 46, and functions as a resistor for air. Further, it is not necessary to form a gap between the heating element 34 and the mandrel 46, and the heating element 34 may be displaced by the pressure when the air flows, so that a slight gap is formed between the heating element 34 and the mandrel 46, and the air flows through the gap.
Further, the heating element 34 has a little gap between the wires adjacent to each other. Thus, air passes between the wires adjacent to each other in the wound heating element 34, on the basis of which the air can also be depressurized. The heating element 34 may have a structure in which no gap is formed between adjacent wires, or a structure in which a slight gap is formed between the wires by a pressure when air flows, and air flows through the gap.
In the temperature-controlled air supply device 10 according to the present embodiment, the cooling unit 25 and the heater 31 are controlled in their capabilities by the control panel 20 based on the temperature detected by the temperature detector 32, and the air (compressed air) introduced into the inlet pipe 16 of the device main body 14 is cooled in the cooling unit 25. The cooling of the cooling unit 25 is not necessarily performed.
The air having passed through the cooling unit 25 is adjusted in flow rate by the flow rate adjusting valve 28, and flows into the pipe 30 through the delivery pipe 18. The air flowing through the pipe 30 flows into the heater 31 and flows through the internal space S1 of the housing 36. The air flows into the housing space S2 housing the heating element 34, and is heated by the heating element 34. In addition, depending on the set target temperature, the air may not be heated by the heating element 34.
When the air flows through the housing space S2 defined by the inner surface of the outer package 36 and the mandrel bar 46, the heating element 34 acts as a resistance to the flow of the air, and therefore the pressure of the air decreases by flowing through the outer package 36. The air having passed through the housing space S2 at a predetermined temperature is blown out from the heater 31 toward the test piece, but the pressure of the air is reduced at this time, and thus the blowing noise is reduced.
As described above, in the temperature-controlled air supply device 10 according to the present embodiment, the air flowing through the pipe 30 flows into the heater 31, and the air having passed through the heater 31 at a desired temperature is blown out toward the test object. The heating element 34 housed in the outer case 36 of the heater 31 serves as a resistor for air flowing in the outer case 36. Therefore, since the pressure of the air decreases while flowing through the exterior body 36, even when the pressurized air is introduced into the pipe 30, the air is heated to a low pressure when being blown out from the heater 31. Therefore, the blowing sound of the air when blown out to the test object can be set to a level that is not noticeable.
Further, in the outer case 36, the pressure of the air is reduced when the air flows between the heating element 34 and the inner surface of the outer case 36, and further, the pressure of the air is reduced when the air flows between the heating element 34 and the outer surface of the core rod 46. Therefore, when the air is blown out from the heater 31, the air becomes low-pressure air whose temperature is controlled, so that it is possible to make it difficult to make the blowing sound of the air when the air is blown out to the test object inconstant.
When air flows into the housing space S2 of the outer package 36 of the heater 31 from the pipe 30, the cross-sectional area of the flow path is reduced to half or less. Thereby, the heater 31 becomes air flow resistance and the air is decompressed. Therefore, the blowing sound of the air when the test object is blown out from the heater 31 can be made less noticeable.
The embodiments disclosed herein are illustrative in all points and should not be construed as being limited thereto. The present invention is not limited to the above-described embodiments, and various modifications, improvements, and the like can be made without departing from the scope of the invention. For example, in the above embodiment, the housing space S2 of the heating element 34 is configured such that air can flow between the inner surface of the outer package 36 and the heating element 34, but the present invention is not limited thereto. It is also possible to employ a structure in which air flows only between the heating element 34 and the core rod 46.
In addition, although the housing space S2 of the heating element 34 is configured such that air can flow between the heating element 34 and the mandrel 46, the present invention is not limited thereto. A structure in which air flows only between the inner surface of the outer case 36 and the heating element 34 may be employed. Further, in the housing space S2 of the heating element 34, a structure is adopted in which air can flow between the inner surface of the outer body 36 and the heating element 34 and between the heating element 34 and the mandrel 46, but the present invention is not limited to this. In the heating element 34, a structure in which air flows only between adjacent wires may be employed.
The cross-sectional area of the portion of the housing space S2 not occupied by the heating element 34 is equal to or less than half of the cross-sectional area in the pipe 30, but the pressure of the introduced air is not limited to this.
As shown in fig. 3, a stirrer 50 capable of stirring air may be provided in the heater 31. The stirrer 50 is for alleviating temperature deviation of the air passing through the heating element 34 in the circumferential direction, and is disposed in a portion (the other end portion 36 d) located on the downstream side of the heating element 34 in the internal space S1 of the outer body 36. By providing the stirrer 50, the temperature of the air blown out from the heater 31 can be suppressed from being biased. Further, by providing the agitator 50, it is also possible to further improve the effect of reducing the blow-out sound.
In fig. 3, the stirrer 50 is disposed upstream of the temperature detector 32 (between the heating element 34 and the temperature detector 32), but instead of this configuration, the stirrer 50 may be disposed at a portion downstream of the temperature detector 32. At this time, the agitator 50 is easily replaced.
As shown in fig. 4, a blow-off pipe 52 having a built-in stirrer 50 may be connected to the second joint 40. The air having passed through the heater 31 is blown out through the blow-out pipe 52. In this case, the stirrer 50 is disposed on both the upstream side and the downstream side of the temperature detector 32. The stirrer 50 provided at the other end 36d of the tube main body 36a (outer package 36) may be omitted.
Here, the embodiments are described in general.
(1) The temperature-controlled air supply device according to the embodiment includes a pipe through which air is introduced and a heater provided at a distal end of the pipe. The heater includes a heating element configured to heat air and an outer case housing the heating element. The heating element functions as a stopper for air flowing in the outer package before being blown out from the heater.
In the temperature-controlled air supply device, air flowing through the pipe flows into the heater, and air having a desired temperature passing through the heater is blown out toward the test object. The heating element housed in the housing serves as a resistor for air flowing in the housing. Therefore, since the pressure of the air is reduced while the air flows through the exterior body, even when the pressurized air is introduced into the pipe, the air is heated and blown out from the heater to be a low-pressure air. Therefore, the blowing sound of the air when blown out to the test object can be set to a level that is not noticeable.
(2) The heating element may also allow air to flow between the heating element and the inner surface of the outer body and act as a barrier to air.
According to this configuration, in the outer case, when air flows between the heating element and the inner surface of the outer case, the pressure of the air is reduced. Therefore, when the air is blown out from the heater, the air becomes low-pressure air whose temperature is controlled, and therefore, the blowing sound of the air when the air is blown out to the test object can be made to be inconsiderable.
(3) The heater may have a core rod formed of an insulator. In this case, the heating element may surround the core rod so as to allow air to flow between the heating element and the core rod, and may function as a resistor for air.
According to this structure, in the outer shell, the pressure of the air is reduced when the air flows between the heating element and the outer surface of the mandrel. Therefore, when the air is blown out from the heater, the air becomes low-pressure air whose temperature is controlled, and therefore, the blowing sound of the air when the air is blown out to the test object can be made to be inconsiderable.
(4) In the case where the heater has a core rod formed of an insulator, the heating element may be disposed in the outer package so as to surround the core rod. In this case, the following may be used: the cross-sectional area of a portion of the space between the inner surface of the outer package and the mandrel, which is not occupied by the heating element, is less than half of the cross-sectional area in the pipe.
According to this configuration, when the fluid flows from the pipe into the portion of the heater housing that accommodates the heating element, the cross-sectional area of the flow path is reduced to less than half. Thereby, the heater becomes air flow resistance and the air is decompressed. Therefore, the blowing sound of the air when the air is blown from the heater to the test object can be made to be inconsiderable.
(5) A stirrer that can stir air may be provided in a portion of the heater located on the downstream side of the heating element. With this configuration, the air blown out from the heater can be prevented from having temperature variations.
As described above, the air blowing sound when the temperature-adjusted air is blown out to the test object can be set to a level that is not intended.
