Title:
PLATE TYPE HEAT EXCHANGER AND REFRIGERATION DEVICE USING IT
Document Type and Number:
Japanese Patent JP3871324
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a plate type heat exchanger for an evaporator capable of enhancing heat transfer performance by equalizing a feed amount of a cooling medium to respective channels of the plate type heat exchanger, and a refrigeration device.
SOLUTION: In the plate type heat exchanger 1 for an evaporator of the refrigeration device, a cooling medium inlet passage 2 is provided in a lower stacked direction of the respective plates and partition plates 5 for dividing at a ratio making right and left areas of the inlet part and the number of the stacked plates in a stacked direction same is provided in the cooling medium inlet passage 2. Orifices 3 or throttle passages for delivering/feeding the cooling medium wet vapor from the divided cooling medium inlet passage 2 to the respective channels are arranged. In the plate type heat exchanger 1, an intermediate partition plate 4 for dividing the whole stacked plates to halves in the stacked direction and feed passages 6 for separately feeding the cooling medium can be provided in the divided cooling medium inlet passage 2. The orifices 3 of the cooling medium inlet passage can be constituted such that the speed of the cooling medium wet vapor passing becomes Mach 0.7-1.0.
