When the hot inside air is drawn to the area around the heat-absorbing section, the working fluid absorbs the heat, vaporizesand immediately ascends inside the pipe.

6 The evaporated fluidreleases the heat at the upper section of the pipe, is cooled by theoutside air, and then condenses and returns to cycle of the absorption of latent heat, heat dissipation, andcondensation is repeated continually inside the heat pipe at conditionAs shown in the figure below, half the length of a super-thermal conductive pipe isimmersed in a hot water bath maintained at 80 C. The graph shows the increasein the temperature of the upper end of the pipe immediately after immersion bycomparing it with the result of a normal copper pipe.* The super-thermal conductive pipeis generally called a heat pipe. Itsprinciple was found by Gaugler(General Motors, ) in 1942and was named by Grover in 1963.

7 Mount the equipment securely with properscrews. Be sure to mount the equipment with its heat-absorbing section at the bottom (for inside aircirculation). Be sure to mount the equipment in a verticalposition. Consider the mounting position carefullybecause objects near the air inlet/outlet willaffect the cooling ability. Take extra care not to cut your fingers orhands with the aluminum fin on the outlet port. Do not use the ENH heat exchanger outdoors. Do not use the equipment in a place where the temperature exceeds or drops below theallowable ambient temperature or where corrosive or flammable gases may be generated. Do not use the equipment in a place where it may be exposed to vibration or shock. Avoid installing the equipment in a place where it may be exposed to vapor or water. Because this is heat-exchanging type cooling equipment, it cannot cool the air inside thecontrol panel to a temperature lower than that of the outside air.

8 Depending on the position of the devices inside the control panel, the air circulation may beinsufficient, resulting in an uneven temperature inside the control panel. In such a case,provide additional appropriate circulation or change the positions of the devices susceptibleto heat to the lower section of the control Mounting the ENH Unit1. Test the machine before installing the unit. Before cutting the control panel, cover the equipment in the panel with a plastic sheet tokeep metal chips out. Install this equipment horizontally or vertically. The securing screws (four) for the protection cover are set on the heat exchanger unitupon product delivery. Make sure to remove the screws before installing the main unit.(These instructions are for the inside-the-panel mount type only. Screws are provided in abag with the outside-the-panel mount type.)

Tighten the screws a crimp terminal (with an insulating cap) to connect the power supply cable to the power supply the fan starts, check that the fan rotates in the proper direction and that there is no abnormalitysuch as vibration or Be sure to use the rated power supply. Check the specifications and provide an appropriate breaker (commercial product) betweenthe heat exchanger and the power supply. Be sure to ground the grounding terminal (FG). Double-check the voltage and wiring before turning on the Note that the internal circulation fan starts continuous operation immediately after thepower is turned careful not to catch your fingers between the operating fan and the fan guard.
