Embodiment 1

[0036] Embodiment 1 provides a kind of low-noise heat exchange equipment, such as figure 1 As shown, it includes a lower air channel 100 , a base plate 200 , a fan unit 400 and an upper air channel 300 , and the fan unit is detachably placed in the space formed by the base plate 200 and the upper air channel 300 .

[0037] The downflow channel 100 is located below the base plate 200 , and the hot air generated by the operation of the machine flows into the heat exchange device from the downflow channel 100 . Above the base plate 200 are the fan unit 400 and the upper air duct 300 , and the hot air flowing through the fan unit 400 flows out through the upper air duct 300 .

[0038]The upper air duct 300 is surrounded by three sides, and the three sides are the left side, the right side and the rear side respectively. The front of the upper air duct 300 is not provided with a closed surface, and the fan unit is assembled and disassembled through the front of the upper air duct....

Embodiment 2

[0046] Embodiment 2 provides a heat exchange system using the above heat exchange equipment, see Figure 5 , on the basis of the heat exchanging device, further comprising a rotational speed monitoring device signally connected to the heat exchanging device, and a rotational speed display unit connected to the rotational speed monitoring device. The rotational speed monitoring device is implemented based on a single-chip microcomputer.

[0047] The heat exchange device is connected to a speed monitoring device for monitoring the speed of the fan through the fan plug 403 . The speed monitoring device is used to detect in real time whether the fan is working normally. Specifically, the fan 401 in the fan unit 400 is a three-wire DC fan. In addition to the common live wire and ground wire, the fan also has a speed monitoring wire. When the fan rotates a circle, the monitoring line outputs a square wave pulse. Within a predetermined time range, the rotational speed of the fan ...

Embodiment 3

[0050] Embodiment 3 provides a real-time monitoring method for heat exchange using the above-mentioned heat exchange system, see Image 6 , including the following steps:

[0051] S1, monitor the rotation of the fan through the speed monitoring line, the fan rotates one circle, and the speed monitoring line outputs a square wave pulse;

[0052] S2. The rotational speed monitoring device detects the number of square wave pulses within a predetermined time range, and judges the running condition of the fan accordingly.

[0053] S3, the speed monitoring device gives an alarm prompt to the faulty fan in the form of a buzzer alarm and / or uploading the speed information of the fan to the speed display unit.

[0054] When multiple fan units are connected, the speed monitoring device detects the speed of each fan separately, and if any fan is damaged, an alarm signal is sent immediately.

Abstract

The invention relates to the field of heat radiators, in particular to low-noise heat exchange equipment and a heat exchange system. The low-noise heat exchange equipment comprises a lower air passage, a base plate, a fan unit and an upper air passage, wherein the fan unit is detachably arranged in a space formed between the base plate and the upper air passage. The low-noise heat exchange equipment has the advantages that the noise influence to the external environment by the operation of the fan is effectively decreased; by adopting the detachable structure, the heat exchange equipment is easily replaced; especially when the fan fails, the quick replacement of the fan is guaranteed, and the influence to the normal running of a machine is avoided. By additionally arranging rotation speed monitoring equipment and a rotation speed display unit, the invention also provides the heat exchange system and a monitoring method of the heat exchange system for monitoring the operation states of the heat exchange equipment in real time, so as to further improve the convenience in use of the heat exchange equipment, and also improve the working efficiency of a working machine used by the heat exchange equipment.

Description

technical field [0001] The invention relates to the field of radiators, in particular to a low-noise heat exchange device and a heat exchange system. Background technique [0002] With the development of my country's electronic industry, the power levels of digital transmitters, FM transmitters, and electronic jammers in various frequency bands are increasing, and the output power is also increasing, and the corresponding heat dissipation requirements are getting higher and higher. Condition monitoring, replacement, and maintenance of heat exchange devices put forward higher requirements. [0003] The heat dissipation fan is generally used in conjunction with the radiator. Its main function is to allow the hot and cold air to exchange heat and effectively reduce the temperature of the electronic device during work. It is an indispensable part of the air-cooled heat dissipation method. Compared with water cooling, natural convection, and phase change heat dissipation, forced ...
