Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a simple test tank used for heat resistance testing of various devices.

[Conventional technology]

Conventionally, in order to perform heat resistance tests on various types of equipment, if the item was small, the test was performed by removing it from the equipment and attaching it to a bracket in a test chamber.

As a result, attachment and detachment are time-consuming and troublesome.

In addition, brackets had to be made each time according to the product being tested, which resulted in high costs and problems.

On the other hand, in order to test large objects, it is necessary to set up a heat resistance test chamber, which poses problems such as construction costs and installation location. I had to ask.

[The problem that the idea aims to solve]

In order to solve the above problems, this invention has developed a heat-resistant test tank that can be used for various types of equipment, whether small or large, and can be easily installed due to its simple configuration. is intended to provide.

[Means to solve the problem]

In order to solve the above problems, the present invention includes a tent 1 that covers an object to be examined, a hot air generator 2 that sends hot air into the tent 1, and a system that senses the temperature inside the tent 1 and controls the hot air generator 2. In a simple heat resistance test chamber consisting of a temperature regulator 3, a ventilation hole 15 for sending hot air into the tent 1 is provided at an appropriate position below the side surface of the tent 1, and a discharge port of the hot air generator 2 is connected to the ventilation hole 15. A chamber box 16 is provided at the discharge port to diffuse and discharge the hot air, and the chamber box 16 has a facing surface facing the discharge port and a side surface, and the facing surface is relatively wide. An opening is provided at a lower position on the opposing surface, an opening is also provided on the side surface other than the lower side surface of the chamber box 16, and an exhaust hole 11 is provided near the lower end of the tent 1. Established.

[Effect]

A chamber box 16 provided at the outlet of the hot air generator 2 discharges hot air at a constant temperature horizontally from above, from the sides, and from below the opposing surface of the chamber box 16 along the side surface of the tent 1. , circulates inside the tent 1, and is finally discharged from an exhaust hole 11 provided near the lower end of the tent 1. This maintains a constant high temperature inside the tent.

〔Example〕

Hereinafter, one embodiment will be described based on the accompanying drawings.

The accompanying drawings all illustrate embodiments of the present invention.

Fig. 1 is an exploded perspective view of the present invention, and 1 indicates the tent, which is approximately box-shaped and consists of a frame and tent fabric, and the tent fabric uses coated glass tent fabric with good heat insulation. This is desirable.
A large number of small diameter exhaust holes 11 are bored near the periphery of the lower end of the tent 1.

Further, a blow hole 15 for blowing hot air is provided at a lower position on one side of the tent. Further, a hole 14 for inserting a sensor of the temperature regulator 3 is provided on the same side as the ventilation hole 15.

A discharge port of the hot air generator 2 faces the ventilation hole 15, and a chamber box, which will be described later, is provided at the discharge port.

FIG. 2 is an explanatory view of the chamber box 16 seen from the inner surface of the tent 1. Reference numeral 12 indicates a frame of the tent, and reference numeral 13 indicates a tent area. The chamber box 16 is connected to the discharge port of the hot air generator 2 facing the ventilation hole 15, has a substantially rectangular parallelepiped shape, has a slightly wider surface facing the discharge port, and has a lower position on the opposite surface. Two openings are provided, and an appropriate number of openings are provided on the top surface and both side surfaces. These openings prevent the hot air from directly hitting the test object, and the hot air is discharged upward, left and right, and horizontally from the lower position of the surface facing the outlet. After being circulated within 1, it flows out from the exhaust hole 11. This keeps the inside of the tent 1 at a constant high temperature.

The hot air generator 2 has a built-in heater of approximately 1KW to 4KW, and is capable of adjusting the blowing temperature within a range of up to 450°C. The output of the heater is adjusted using a dial 21 on the front of the hot air generator 2. Although not shown, it is equipped with a main switch, a fan switch, and a heater switch like a normal hot air generator.

The temperature controller 3 is adjusted by turning ON/OFF, but if a hot air generator having an inverter function that automatically adjusts the output is used, it may have a function that simply sends a temperature signal.

Next, how to use the present invention will be explained.

The test object A is placed on a table such as a block, and the tent 1 is assembled and covered.

A temperature regulator 3 is fixed to the side of the tent 1.

The sensor 31 of the temperature regulator 3 is inserted into the tent 1. The mounting position of the sensor 31 is changed depending on the size of the test object A, etc.

Connect the hot air generator 2 to the ventilation hole 1 on the side of the tent 1.
5 and connect it to the temperature controller 3.

Adjust the dial 32 of the temperature controller 3 to the specified temperature.

The temperature of the hot air generator 2 is set higher than the test temperature to increase the heating capacity. this is. This is to quickly warm up the test object A to a temperature at which it can be tested.

After the temperature inside the tent 1 becomes constant, the heating capacity of the hot air generator 2 is set to an appropriate value, and the test is started.

During the test, the hot air generator 2 is connected to the temperature controller 3
The temperature inside tent 1 is kept constant by repeatedly turning on and off.

When tested using the test chamber of this example, it was possible to obtain a temperature distribution accuracy of ±2° C. with a heating time of 15 minutes.

Furthermore, in this example, the material of the tent fabric was set and selected for testing up to 100°C, but by changing the material, it is possible to perform heat resistance tests up to 200°C.

Although the embodiments have been described above, the size, shape, material, etc. of each component can be changed as desired.

[Effect of idea]

A heat resistance test tank can be easily assembled and installed using a hot air generator or the like.

A constant high temperature condition can be easily created by constantly discharging hot air within the tent, circulating it, and exhausting it to the outside.

Due to the structure of the chamber box, the hot air does not directly hit the test object, and it circulates efficiently within the tent, allowing the interior of the tent to be maintained at a constant high temperature.

Hot air is circulated through the tent through exhaust holes provided at the lower end of the tent, and then efficiently exhausted, thereby maintaining the inside of the tent at a constant high temperature.

As described above, the present invention has a simple structure and has significant effects.
