A liquid to refrigerant heat exchanger includes an enclosed coolant volume that is at least partially defined by a plastic housing and by a metal closure plate. The metal closure plate can be part of a brazed assembly containing a continuous refrigerant flow path. The refrigerant flow path is disposed within the coolant volume, where heat can be transferred between the refrigerant within the refrigerant flow path and the liquid within the coolant volume. The plastic housing can at least partially surround the refrigerant flow path to at least partially bound a liquid flow path along a portion of the coolant volume. An inlet diffuser and an outlet diffuser can be mounted to the housing to direct the liquid through the housing. The plastic housing is sealingly joined to the closure plate along an outer periphery of the closure plate.

High pressure capable liquid to refrigerant heat exchanger

A liquid to refrigerant heat exchanger includes a coolant volume that is at least partially defined by a plastic housing and by a metal closure plate. The plastic housing is sealingly joined to the closure plate along an outer periphery of the closure plate. The metal closure plate can be part of a brazed assembly that defines a continuous refrigerant flow path through the heat exchanger between a refrigerant inlet port and a refrigerant outlet port.

The invention relates to a concrete compacting device for compacting plastically deformable concrete in a formwork, comprising at least one vibrating unit which is attached to the formwork and has a vibration-generating unit. The compacting device is characterized in that the vibrating unit comprises an acceleration sensor for generating a signal corresponding to a vibration generated by the vibration-generating unit at the level of the formwork, and a control unit which is impinged upon by said signal and serves to control operating parameters of the vibration-generating unit.
