Problems solved by technology
Limited by more than 80% of the height difference, the overall heat exchanger is not compact enough
Chinese patent CN201010153985.3 discloses a separated phase-change heat exchanger. The flat tubes used in the evaporator and condenser are provided with fins, but the thickness of the root of the fins occupies the flow area and increases the flow resistance.
At the same time, the fins are inserted into the flat tube, the process is complicated

Provided is a heat pipe cooling device. The heat pipe cooling device comprises a machine shell, a separating plate, a heat pipe exchanger, an outer circulating fan and an inner circulating fan, wherein the outer circulating fan is arranged in an outer circulating air duct, the inner circulating fan is arranged in an inner circulating air duct, the interior of the machine shell is divided by the separating plate into the outer circulating air duct and the inner circulating air duct, the heat pipe exchanger comprises a condenser arranged in the outer circulating air duct, an evaporator arranged in the inner circulating air duct, a steam ascending pipe arranged between an outlet of the evaporator and an inlet of the condenser, and a liquid descending pipe connected between an outlet of the condenser and an inlet of the evaporator, the core of the condenser is formed by a set of parallel abreast flat tubes, the core of the evaporator is formed by a set of parallel abreast flat tubes, the inlet of the condenser is higher than the outlet of the evaporator, a fin is arranged between every two adjacent flat tubes, the fins and the corresponding flat tubes are connected into a whole in a brazing mode, and according to the flat tubes of the condenser and the flat tubes of the evaporator, each flat tube is a porous flat tube internally provided with a plurality of longitudinal vertical ribs, a plurality of thin flow passes are arranged in each porous flat tube, the structural strength is improved due to the vertical ribs, and the circulation area is ensured at the same time. The heat pipe cooling device is simple in structure and technology.
Description
technical field [0001] The invention relates to an air heat exchanger used in the field of industry and communication for cooling heat-generating parts such as electronic components installed in a closed box cavity. Background technique [0002] Existing cooling devices can house electronic components with semiconductors and the like inside in a closed box, that is, a closed casing, to prevent malfunctions caused by deposition of dust, debris, moisture, and the like. In this case, since the above-mentioned electronic component is a heat-generating element, it is necessary to cool the inside of the casing, but it is not possible to directly blow external air into the casing to cool the heat-generating element. Therefore, the prior art provides a cooling device using a heat exchanger composed of a heat pipe or the like, which exchanges heat between high-temperature air inside the casing and low-temperature air (outside air) to cool the casing. internal.
