A valve includes a housing including a plurality of ports including an inlet port in communication with a radiator. The valve includes a cylinder located in the housing that includes a plurality of apertures and a fail safe opening. The cylinder is moveable such that one of the plurality of apertures can be aligned with one of the plurality of ports of the housing to determine a flow of a fluid through the valve. The valve includes a moveable feature moveable with and relative to the cylinder, and the moveable feature covers the fail safe opening of the cylinder when a temperature of the fluid flowing through the valve is below a threshold temperature.

FIELD COIL ASSEMBLY OF ELECTROMAGNETIC CLUTCH FOR COMPRESSOR
The present invention relates to a field coil assembly of an electromagnetic clutch for a compressor. The present invention comprises a core 210, and a coil 240 installed to the core 210 and formed by winding a unit wire 250. At this time, the unit wire 250 wound on the coil 240 is made of aluminum, and an area ratio R of an inner sectional area M of the core 210 to a cross-sectional area of the unit wire 250 is 400 to 640. According to the present invention as above, since the unit wire 250 used for the coil 240 is made of aluminum with a small specific weight and low price rather than copper, the weight of the field coil assembly 200 is decreased to improve fuel efficiency of a vehicle and decrease a production cost of the field coil assembly 200.

The present invention relates to an evaporator, and more particularly, to an evaporator which can restrict a surface area of a communication hole with respect to a cross sectional area of a compartment and a surface area of a tube with respect to a surface area of a fin, thereby providing a dimensional extent for maximizing the heat exchange efficiency. Therefore, by optimizing a relation between the surface area of the communication portion and the surface area of the compartment of the first header tank and dimensions for each surface area and the heights of the tube and fin, the present invention provides a dimensional extent for maximizing the heat radiation amount, reducing the maximum temperature deviation of the core portion and allowing the refrigerant and air to be smoothly flowed, thereby maximizing the heat exchange efficiency.

A fluid pump (10) includes a pumping chamber (14), an inlet (16) and an outlet (18) fluidly connected with the pumping chamber, and a passage (24) fluidly connected between the inlet and the outlet. Fluid flowing through the passage bypasses the pumping chamber. In one example, the fluid pump (10) pumps coolant within a vehicle cooling system between a heater core (23b) and a vehicle engine (23a).
A shell tube and heat exchanger (10) includes a plurality of tubes surrounded by a shell (16). Each tube (12) includes a plurality of indentations. A mold is placed in a desired positions and orientation in a die. A tube is placed in a first position within a die, and the mold crimps the tube to form the desired indentation in the tube. The mold is then released, and the tube is moved relative to the mold to a second position. The mold again crimps the tube to form an additional indentation. Alternately, the mold includes a roller that forms a groove on the tube. The tube is translated or both translated and rotated relative to the mold to form the groove.
