Cooler for heater-containing box

Abstract

There is provided a cooler for heater-containing box in which an outside air fan for carrying air on an outside air path and an inside air fan for carrying air on an inside air path are arranged such that a rotating shaft of each fan is in parallel with an air intake direction, and a heat exchanger for exchanging sensible heat of outside air and inside air is arranged between the outside air path and the inside air path such that a suction port at a longitudinal air-path side of the heat exchanger is aligned with a blowout port of the fan. The cooler for heater-containing box capable of making the depth thinner can be provided.

Description

technical field [0001] The present invention relates to a box structure installed outdoors, which has heating elements such as electronic components inside, which generate a large amount of heat, requires cooling even in winter, and has performance and lifespan that are greatly affected by temperature. Cases for precision machines, especially as regards their cooling devices. Background technique [0002] In recent years, the high performance of electronic components and the high density of electronic components relative to control substrates have increased, and the amount of heat generated from the control substrates has increased dramatically. Along with this, the temperature inside the box tends to rise, and the operation assurance and product life of the electronic components on the control board are greatly affected by the temperature inside the box. Therefore, reliability cannot be ensured unless the temperature in the box is cooled below a certain level. [0003] Fo...

Problems solved by technology

[0026] In addition, when thermally welding the outer peripheral sides of the laminated heat transfer plates, there is a problem that the height of the opening on the outer peripheral side and the height of the air passage may decrease due to thermal shrinkage, and it is required to ensure the height of the opening on the outer peripheral side and the height of the air passage to suppress increase in ventilatory resistance

[0027] In addition, in thermal welding, there is a problem that man-hours are spent on welding work to prevent welding failures, and it is required to reduce man-hours of welding work and improve productivity

[0028] In addition, when the excess thin plate is cut off from the heat transfer plate, burrs (burrs) remain at the inlet or outlet of the air passage, and during heat welding, the opening height of the inlet or outlet may decrease and the airflow resistance may increase due to the burrs. Big problem, it is required to prevent the reduction of the opening height due to the burr and suppress the increase of the ventilation resistance
