Description

Technical Field

[0001] The utility model relates to the technical field of aging experiment, in particular to a heating device for an aging test chamber. Background Art

[0002] A high-temperature aging test chamber is a common experimental device used to simulate the aging of items in a high-temperature environment. Its heating principle is to provide heat energy through heating elements to raise the temperature inside the test chamber, thereby realizing the high-temperature aging test of items.

[0003] Currently, the heating components used in aging test chambers are usually fixed inside the chamber body. When performing maintenance and repair on them, it is necessary to disassemble the chamber body itself, which is troublesome. Moreover, the air circulation of the heating device is poor, resulting in a poor effect of uniformly heating the products.

[0004] Therefore, we propose a heating device for an aging test chamber to solve the existing problems. Content of the Utility Model

[0005] The purpose of the utility model is to propose a heating device for an aging test chamber aiming at the problems existing in the background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A heating device for an aging test chamber includes a chamber body and a substrate. The substrate is provided at the rear opening of the chamber body through bolts. The upper air plate and the lower air plate are symmetrically provided on the substrate. The upper air plate and the lower air plate are slidably inserted into the interior of the chamber body. Air ducts are provided on both the upper air plate and the lower air plate. The two air ducts are interconnected through a pump transmission assembly. Two electric heating components are respectively provided on the upper air plate and the lower air plate.

[0007] Preferably, a chamber door is rotatably installed at the front opening of the chamber body through a hinge. A sealing structure is provided on the joint surface of the chamber door and the chamber body. A door handle is installed on the outer surface of the chamber door through bolts.

[0008] Preferably, sliders are installed on both the upper air plate and the lower air plate. Two sliding grooves adapted to the sliders are symmetrically opened on the inner wall of the chamber body. The two sliders are respectively slidably inserted into the two sliding grooves.

[0009] Preferably, the pump transmission assembly is composed of a discharge pipe, a pump body and a suction pipe. The pump body is provided on the outer surface of the substrate.

[0010] Preferably, the discharge pipe is provided at the discharge end of the pump body. The air duct of the upper air plate is interconnected with the discharge pipe.

[0011] Preferably, the suction pipe is provided at the suction end of the pump body. The air duct of the lower air plate is interconnected with the suction pipe.

[0012] Preferably, the electric heating component is composed of an electric heating rod and a machine base. The two machine bases are respectively fixed on the upper air plate and the lower air plate, and the two electric heating rods are respectively fixed in the two machine bases.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] During the use of the heating device for the aging test chamber of the present utility model, a placement rack can be placed inside the box body of the aging test chamber, and then the product is placed on the placement rack and the box body is closed. After connecting to an external power supply, the electric heating component works to generate heat;

[0015] Meanwhile, the pump body works. The pump body sucks the air inside the box body, and drives the air inside the box body to circulate internally through the air duct under the drive of the pump transmission component. During the process of air internal circulation, the air continuously contacts the working electric heating component, so that the air is uniformly heated to complete the uniform heating action of the product;

[0016] At the same time, when it is necessary to repair the heating device, only the substrate needs to be removed, so that the substrate together with the upper air plate and the lower air plate is separated from the box body of the aging test chamber, and then the electric heating component on it can be repaired and maintained;

[0017] The present utility model adopts a split design, which can facilitate the disassembly, assembly and maintenance of the heating structure of the aging test chamber by personnel. At the same time, it strengthens the internal air circulation of the aging test chamber and improves the effect of uniformly heating the product. Description of the Drawings

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1

[0026] As Figures 1 - 4 shown, a heating device for an aging test chamber proposed by the present utility model includes a box body 1 and a substrate 2. The substrate 2 is provided at the rear opening of the box body 1 through bolts. Upper wind plates 9 and lower wind plates 12 are symmetrically provided on the substrate 2. The upper wind plates 9 and the lower wind plates 12 are slidably inserted into the interior of the box body 1. Air ducts 13 are provided on both the upper wind plates 9 and the lower wind plates 12. The two air ducts 13 are interconnected through a pump transmission assembly. Two electric heating components are respectively provided on the upper wind plates 9 and the lower wind plates 12.

[0027] Based on Embodiment 1:

[0028] During the use of the heating device for the aging test chamber of the present utility model, a placement rack can be placed inside the box body 1 of the aging test chamber, and then the product can be placed on the placement rack and then the box body 1 is closed. Connect to an external power supply, and at this time the electric heating component works to generate heat;

[0029] Meanwhile, the pump body 6 works, and the pump body 6 sucks the air inside the box body 1. Driven by the pump transmission assembly, the air inside the box body 1 undergoes internal circulation through the air ducts 13. During the internal circulation of the air, the air continuously contacts the working electric heating component, so that the air is evenly heated to complete the uniform heating action of the product;

[0030] At the same time, when it is necessary to repair the heating device, only the substrate 2 needs to be removed, so that the substrate 2 together with the upper wind plate 9 and the lower wind plate 12 is separated from the box body 1 of the aging test chamber, and then the electric heating component thereon can be repaired and maintained.

[0031] Embodiment 2

[0032] As Figures 1 - 4 shown, a heating device for an aging test chamber proposed by the present utility model, compared with Embodiment 1, further includes: a box door 3 is rotatably installed through a hinge at the front opening of the box body 1. A sealing structure is provided on the joint surface of the box door 3 and the box body 1. A door handle 4 is installed on the outer surface of the box door 3 through bolts. Through the design of the box door 3, it is convenient to control the opening and closing state of the box body 1.

[0033] Slider 8 is installed on both the upper air plate 9 and the lower air plate 12. Two sliding grooves adapted to the slider 8 are symmetrically formed on the inner wall of the box body 1. The two sliders 8 are respectively slidably inserted into the two sliding grooves. Through the sliding cooperation of the slider 8 and the sliding groove, the movement tracks of the upper air plate 9 and the lower air plate 12 can be limited, and the installation stability of the upper air plate 9 and the lower air plate 12 can be increased.

[0034] The pumping component is composed of a discharge pipe 5, a pump body 6 and a suction pipe 7. The pump body 6 is arranged on the outer surface of the base plate 2. The discharge pipe 5 is arranged at the discharge end of the pump body 6. The air duct 13 of the upper air plate 9 is communicated with the discharge pipe 5. The suction pipe 7 is arranged at the suction end of the pump body 6. The air duct 13 of the lower air plate 12 is communicated with the suction pipe 7. The pump body 6 is powered on for operation. The air inside the box body 1 is sucked through the air duct 13 of the lower air plate 12. During the air flow process, the air contacts the electric heating component on the lower air plate 12. The sucked air is re-discharged into the box body 1 through the air duct 13 of the upper air plate 9. During the exhaust process, the air contacts the electric heating component of the upper air plate 9. Thus, the air is uniformly heated during the internal air circulation.

[0035] The electric heating component is composed of an electric heating rod 10 and a machine base 11. The two machine bases 11 are respectively fixed on the upper air plate 9 and the lower air plate 12. The two electric heating rods 10 are respectively fixed in the two machine bases 11. The electric heating rod 10 is powered on for operation to generate heat.

[0036] It should be noted that the structures of the pump body 6 and the electric heating rod 10 are existing mature technologies. Their working principles and internal structures are known to those skilled in the art. The present utility model only utilizes their functions and does not improve their internal structures. Therefore, no detailed description is given here. Those skilled in the art can make any optional selection according to their needs or convenience.

[0037] The above specific embodiments are only several preferred embodiments of the present utility model. Based on the technical solution of the present utility model and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

[0038] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.
