Title:
REFRIGERANT EVAPORATOR OF NO-CIRCULATION PUMP OF ABSORPTION TYPE REFRIGERATION UNIT, REFRIGERATION UNIT AND MATRIX
Document Type and Number:
WIPO Patent Application WO/2017/088772
Kind Code:
A1
Abstract:
Provided are a refrigerant evaporator (101) of a no-circulation pump of an absorption type refrigeration unit, an absorption type refrigeration unit and a refrigeration matrix. The refrigerant evaporator (101) of the no-circulation pump comprises: a plurality of diversion grooves (204) arranged in an upper and lower layers. Heat transfer tubes (203, 305) are laid over the respective layers of the diversion grooves (204). A refrigerant water flows outside the heat transfer tubes (203, 305). Cold water is circulated inside the heat transfer tubes (203, 305). A plurality of discharge holes (302) are provided on the side wall of the diversion groove (204) to enable the refrigerant water to flow to the diversion grooves (204) at the lower layer, so as to keep the refrigerant submerging the heat transfer tubes (203, 305). The refrigerant evaporator (101) of the non-circulation pump uses the heat transfer tubes (203, 305) having the small diameter, the thin wall and the large density, to obtain the larger heat exchange area per unit volume so as to meet the requirements of small volume and high heat exchange efficiency. The diversion groove (204) for guiding a flow is provided below each row of the heat transfer tubes (203, 305) to allow the refrigerant water to contact with and have heat exchange with the heat transfer tubes (203, 305) in the diversion groove (204), and to allow the refrigerant water flowing in a shell pass not to have to fill all of the space of the shell pass and to only necessarily submerge the the heat transfer tube (203,305).
