Problems solved by technology

[0005] 1. The air cannot circulate in a large area throughout the aging room, resulting in uneven temperature in the aging room and affecting the quality of the aging test
[0006] 2. An aging room often needs at least three fans to achieve heating and cooling
Too many fans and the setting of air inlets waste resources

specific Embodiment approach

[0020] figure 1 , 2 Shown is an embodiment of the present invention. In this embodiment, the hot air circulation system includes an air duct system arranged inside the main body 1 of the aging room. The air duct system is a circulating air duct 4, and the circulating air duct 4 is provided with Four air outlets 2.1, 2.2, 2.3, 2.4 and two return air outlets 5.1, 5.2. The four air outlets 2.1, 2.2, 2.3, 2.4 are installed on the top surface of the aging room. The number of air outlets is based on the aging room. The size and use of the internal space require a symmetrical and even distribution. In this embodiment, there are four. The air outlets are arranged symmetrically with the main air duct of the circulating air duct. The air return 5 is arranged at the bottom of the aging room. At appropriate positions, in this embodiment, two return air ports 5 are symmetrically arranged on both sides of the circulating air duct. The above-mentioned circulating air duct 4 is also provided wi...

Abstract

The invention relates to a hot air circulating system which is specifically applied for carrying out heating, heat preservation and cooling on the air in a burn-in room and is capable of enabling the temperature in the burn-in room to be circulated in a large scale, enabling the temperature in the burn-in room to be more uniform and reducing the number of draught fans in the burn-in room under the situation that heating, heat preservation and cooling technologies of the burn-in room is ensured. The hot air circulating system comprises a circulating air duct system, wherein the circulating air duct system is arranged at the inner part of a burn-in room main body and is provided with four air outlets and two air return inlets, the air outlets are arranged on an air duct on the inner top surface of the burn-in room, the air return inlets are arranged at the inner bottom end of the burn-in room, the two air return inlets are symmetrically arranged at two sides of a circulating air duct on the inner side wall of the burn-in room, the circulating air duct is also internally provided with a circulating draught fan and an indoor heat exchanger, the circulating draught fan is driven to rotate through a draught fan motor, the indoor heat exchanger is a condenser or an evaporator in a heat pump system, and the circulating draught fan and the indoor heat exchanger respectively have the function of heating or refrigerating the air in the circulating air duct.

Description

Technical field [0001] The invention relates to a hot air circulation system, which is specifically applied to heating, heat preservation and cooling of air in an aging room. Background technique [0002] Electrical aging room is an equipment that simulates a high temperature and harsh test environment for high-performance electronic products. It is an important test equipment to improve product stability and reliability. This equipment has been widely used in power electronics, computers, communications, biopharmaceuticals, etc. field. [0003] The air circulation of the current aging room is mainly circulated through the outlet air ducts and the air inlet air ducts arranged on both sides of the inner wall of the aging room. The heating is mainly realized by the circulating air of the fans and pipes. The cooling is generally in the aging room Install exhaust fans in other locations. [0004] The existing technology has the following disadvantages: [0005] 1. The air cannot circula...
