Claims

[Scope of utility model registration request]

(1) In a cooling system installed under the floor of a vehicle, the bottom of the case with the evaporator installed inside is sloped so that the upstream side of the evaporator is lower than the downstream side of the evaporator in the air flow direction, and the evaporator inside the case is A water reservoir for condensed water to collect on the bottom surface on the more upstream side and a drain hole for draining the condensed water collected in the water reservoir are provided, and a drain hole is provided to drain the condensed water collected in the water reservoir from the liquid receiver to the expansion valve. A vehicle cooling device characterized by being provided with a cooling section that cools a refrigerant.

(2) The cooling unit has a structure in which a refrigerant conduit from a liquid receiver to an expansion valve is disposed in condensed water accumulated in a water reservoir. The vehicle cooling device described.

(3) In the cooling section, a refrigerant conduit from the liquid receiver to the expansion valve is installed at the lower part of the outside of the drain hole, which is a slit-shaped or many small holes, through which the condensed water accumulated in the water reservoir flows to the outside. 2. The vehicle cooling device according to claim 1, wherein the condensed water flowing down from the drain hole wets the outer peripheral surface of the refrigerant conduit.

(4) The scope of the utility model registration claim, characterized in that the cooling unit has a structure in which condensed water seeps into a water-retaining cloth provided on the outer peripheral surface of the refrigerant conduit leading from the liquid receiver to the expansion valve. 1st
The vehicle cooling device described in 2.

(5) The cooling unit has a structure in which a water-absorbing porous block is attached to a notch in the water reservoir, and a refrigerant conduit is passed from the liquid receiver to the expansion valve under or within the block. A vehicle cooling device according to claim 1, characterized in that:
