Abstract
The utility model discloses an air circulation system of an ageing room for a heat pump electronic product. The system consists of a fan, air flues, air intakes and an air return port. According to the system, a heat source is provided for the ageing room by a heat pump unit, heat energy is fed into the air flues by the fan, the heat energy is fed into the ageing room from the air intakes, and air in the ageing room is sucked into the air flues by the air return port to realize the air circulation of the ageing room under the action of the fan. Through the hot air circulation system, the problem that the distribution of the temperature in the ageing room is not uniform is solved, and the goal that temperature measurement is simultaneously performed on multiple points in an ageing area is achieved, and therefore, the uniformity of the temperature in the ageing room is effectively guaranteed. According to the air circulation system of the ageing room for the heat pump electronic product disclosed by the utility model, the problems that the distribution of the temperature in the ageing area in a traditional ageing room is not uniform and single-point temperature measurement is inaccurate can be effectively solved.
Description
Technical field
The utility model relates to a kind of air circulation system of heat pump electronic product burn-in chamber.
Background technology
Along with development of electronic technology, the integrated degree of electronic product is more and more higher, and structure is more and more trickleer, and operation is more and more, and manufacturing process becomes increasingly complex, and can produce the defective of hiding like this in manufacture process.To a good electronic product, not only requiring has higher performance indications, but also advantages of higher stability will be arranged.The stability of electronic product depends on the factors such as reasonability, components and parts performance and complete machine manufacturing process of design.At present, generally adopt high temperature ageing technology to improve stability and the reliability of electronic product both at home and abroad, by high temperature ageing the hidden danger that exists in the production processes such as defective, welding and assembling of components and parts is exposed in advance, the product that assurance is dispatched from the factory can be stood the test of time.The uniformity coefficient of burn-in chamber temperature inside will influence the accurate judgement of system, when the temperature inside skewness, the signal that Temperature sampler is gathered will produce error, and the control signal of control system produces error, finally cause too high, the tested electronic product damage of temperature in the burn-in chamber.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of air circulation system of heat pump electronic product burn-in chamber, has characteristics easy to use simple in structure.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of air circulation system of heat pump electronic product burn-in chamber, this system is made up of blower fan, air channel, air inlet and return air inlet, this system provides thermal source by source pump for burn-in chamber, by blower fan heat energy is sent in the air channel, from air inlet heat energy is sent in the burn-in chamber, by return air inlet the air in the burn-in chamber is drawn in the air channel, under the effect of blower fan, realizes the air circulation of burn-in chamber.Solve the difficult problem of temperature distributing disproportionation in the burn-in chamber by hot air circulating system, and realized the multiple spot in the aging zone is carried out the purpose of thermometric simultaneously, thereby effectively guaranteed the uniformity of temperature in the burn-in chamber.
Lay along the inwall of burn-in chamber in described air channel, air inlet is arranged on the top of burn-in chamber, form air-supply structure with the air channel that lay at the top, lower openings place, air channel installs back the air port, arrange in the air channel hot-air that will produce through heat pump from air outlet send continuously and the zone of will wearing out air suck the blower fan in air channel continuously from return air inlet.
Described air circulation system has a plurality of return air inlets and a plurality of air inlet, makes its area coverage to aging zone increase greatly, has effectively guaranteed the even intensification in aging zone.
Compared with prior art, the utility model circulates by the air to burn-in chamber, make the burn-in chamber temperature inside even, make the electronic product of test be in identical hot environment, the detected indoor temperature of Temperature Detector is accurate, make control system receive temperature signal accurately, make corresponding control signal, can effectively overcome in the existing burn-in chamber temperature distributing disproportionation in the aging zone and, the inaccurate problem of single-point thermometric.
Description of drawings
Fig. 1 is the air circulation schematic diagram of heat pump electronic product burn-in chamber of the present utility model.
Fig. 2 is heat pump electronic product burn-in chamber air circulation system vertical view of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is carried out more detailed explanation.
Be illustrated in figure 1 as the air circulation system schematic diagram of heat pump electronic product burn-in chamber of the present utility model, this system is made up of blower fan, air channel, air inlet and return air inlet, this system provides thermal source by source pump for burn-in chamber, by blower fan heat energy is sent in the air channel, from air inlet heat energy is sent in the burn-in chamber, by return air inlet the air in the burn-in chamber is drawn in the air channel.Under the effect of blower fan, realize the air circulation of burn-in chamber.Lay along the inwall of burn-in chamber in the air channel as shown in Figure 2, and air inlet is arranged on the top of burn-in chamber, and lower openings place in air channel installs back the air port, constitutes circulation air path.Solve the difficult problem of temperature distributing disproportionation in the burn-in chamber by air circulation system, and realized the multiple spot in the aging zone is carried out the purpose of thermometric simultaneously, thereby effectively guaranteed the uniformity of temperature in the burn-in chamber.
Specific implementation process of the present utility model is: the air in the burn-in chamber enters the air channel from return air inlet, and move along the air channel, and behind heating blower and heater, air themperature is raised, get back in the aging chamber from air inlet through the air channel again, so just realized the whole evenly purpose of heating is carried out in aging zone.High air circulation system has a plurality of return air inlets and a plurality of air inlet, makes its area coverage to aging zone increase greatly, has effectively guaranteed the even intensification in aging zone.In the hydronic process of room air, be positioned at indoor a plurality of thermocouples and realize respectively the temperature of each point is detected, in time grasp the Temperature Distribution situation in aging zone, thereby effectively avoided spot measurement to cause the inaccurate drawback of temperature survey.
