Ventilation and heat exchange device of control cabinet

Abstract

The invention belongs to the field of ventilation and heat exchange equipment. The ventilation and heat exchange device of the control cabinet comprises a control cabinet body; the control cabinet body is of a rectangular structure; fixed bases are fixedly installed at the outer walls of the periphery of the bottom of the control cabinet body; each fixed base is of a rectangular structure; a threaded hole is formed in the outer wall of the top of each fixed base; a cabinet door is movably connected to one side of the outer wall of the front surface of the control cabinet body through a rotating shaft; a window of a rectangular structure is formed in the outer wall of the front surface of the cabinet door; and a locking clamping buckle is rotationally connected to the outer wall of the side, close to the window, of the cabinet door. With the ventilation and heat exchange device of the invention adopted, the interior of a pressure measuring instrument can be observed in time; emergency situations in a test process can be effectively avoided; safety performance is improved; a ventilation effect in the control cabinet body can be timely and effectively achieved; the service lives of electronic components are prolonged; and a dustproof effect and a damp-proof effect in the control cabinet body can be well achieved.

Description

technical field [0001] The invention relates to the field of ventilation and heat exchange equipment, in particular to a ventilation and heat exchange device for a control cabinet. Background technique [0002] Ventilation and heat exchange equipment is widely used in daily production and life. The more common ventilation and heat exchange equipment includes hot air circulation ovens and low-pressure vacuum vacuum drying ovens. Hot air ovens cannot be used for dry materials, and there are often not only one type of product produced by a factory, which makes the factory need to prepare two sets of ventilation and heat exchange equipment, which greatly increases the cost of the process. The melting point of phenylpyruvate is only 17°C, while its other product, 4-biphenylmethanol, has a very high melting point, which can be satisfied by a hot air oven.

[0002] Ventilation and heat exchange equipment is widely used in daily production and life. The more common ventilation and heat exchange equipment includes hot air circulation ovens and low-pressure vacuum vacuum drying ovens. Hot air ovens cannot be used for dry materials, and there are often not only one type of product produced by a factory, which makes the factory need to prepare two sets of ventilation and heat exchange equipment, which greatly increases the cost of the process. The melting point of phenylpyruvate is only 17°C, while another product, 4-biphenylmethanol, has a very high melting point, which can be satisfied by a hot air oven.

[0003] Common hot air oven, such as Chinese Patent Publication No.: CN202853277U, in the patent document on April 3, 2013, discloses a hot air circulation oven, including: a main box, one side of which is provided with a box door, and the box door The adjacent side plates are the first side plate and the second side plate; the drying box is arranged inside the main box, and the side plate adjacent to the first side plate of the drying box is the third side plate; The side plate adjacent to the side plate is the fourth side plate; the third side plate and the fourth side plate are provided with a ventilation device; a fan; a heating device is installed at the air outlet of the fan; between the top plate of the main box and the top plate of the drying box The first air passage is formed; the second air passage is formed between the second side plate and the fourth side plate; the third air passage is formed between the first side plate and the third side plate, and the ventilation device of the drying box in the above-mentioned hot air circulation oven The size of the air vent can be adjusted, the air intake is easy to control, and the temperature is easy to control. The principle of this type of drying oven is doomed to the limitation of the object to be dried. It cannot be used for drying heat-sensitive objects, and the drying equipment needs to be replaced.
