THERMAL CONDITIONING MODULE WITH ACCUMULATION DEVICE
A heat treatment module for a heat treatment system of a vehicle is disclosed. The heat treatment module includes a first heat exchanger, a second heat exchanger, and an internal heat exchanger. The first heat exchanger and the second heat exchanger both are configured to bring about an exchange of heat between a refrigerant fluid and a heat transfer liquid. The internal heat exchanger is configured to bring about an exchanger of heat between the refrigerant fluid, which is subjected to two different temperature levels in the heat treatment system. The heat treatment module includes an accumulation device configured to contain the refrigerant fluid. The internal heat exchanger includes a platform on which the accumulation device is disposed.
EJECTOR-INTEGRATED HEAT EXCHANGER
An ejector-integrated heat exchanger includes multiple tube forming members. The tube forming member includes an ejector, a flow-out side refrigerant passage, and a suction side refrigerant passage. The ejector includes a nozzle portion decompressing a refrigerant, a refrigerant suction port, and a pressure increasing portion in which the refrigerant drawn from the refrigerant suction port and the refrigerant jetted from the nozzle portion are mixed, a pressure of the mixed refrigerant being increased in the pressure increasing portion. In the flow-out side refrigerant passage, the refrigerant flowing out of the pressure increasing portion performs heat exchange while flowing. In the suction side refrigerant passage, the refrigerant that is to be drawn through the refrigerant suction port performs heat exchange while flowing. Multiple tube forming members are arranged such that the refrigerant flows in parallel with each other.
Evaporator
An evaporator includes multiple refrigerant tubes, multiple air passages provided between the refrigerant tubes, a cold storage container disposed in the multiple air passages, and a temperature detector. The evaporator further includes a freezing allowable region and a freezing unallowable region that is provided above the freezing allowable region. The cold storage container has a small thickness region and a large thickness region that is positioned above the small thickness region. The large thickness region demarcates a smaller space with the refrigerant tubes than the space demarcated between the small thickness region and the refrigerant tubes. The small thickness region of the cold storage container is positioned within the freezing allowable region, the large thickness region is positioned in the freezing unallowable region, and the temperature detector is disposed in the freezing allowable region.
Refrigeration system with integrated core structure
A refrigeration system includes a core comprising a stack of core plates. The core defines a condenser, an evaporator and a refrigerant reservoir. The condenser has a plurality of refrigerant flow passages and a plurality of first coolant flow passages in alternating arrangement. The evaporator has a plurality of refrigerant flow passages and a plurality of second coolant flow passages in alternating arrangement. The condenser has a refrigerant outlet in flow communication with the refrigerant inlet of the refrigerant reservoir, where the refrigerant side of at least one of said core plates includes a refrigerant communication passage providing flow communication between the refrigerant outlet of the condenser section and the refrigerant inlet of the reservoir section.
HEAT EXCHANGE DEVICE
A heat exchange device includes a heat exchanger and a mounting plate for fixing the heat exchange device, and includes first and second flow passages which are not in communication with each other. The mounting plate includes a communication hole, a protruding portion and a mounting hole. The protruding portion protrudes outwards from the front side of the mounting plate. The mounting hole extends through the protruding portion and the mounting plate and includes a valve core receiving cavity. The valve core receiving cavity is in communication with the communication hole via a connection groove at a back side of the mounting plate; the mounting plate is fixed to the heat exchanger in a sealed manner, the mounting hole is in communication with the first flow passage, and the communication hole is in communication with the first flow passage via the connection groove and the mounting hole.
System and method for dynamic control of an evaporator
The invention relates to a plate heat exchanger including a plate package, which includes a number of first and second heat exchanger plates which are joined to each other and arranged side by side in such a way that first and second plate interspaces are formed. At least two injectors are provided, each injector being arranged to supply a first fluid to at least one of the first plate interspaces in the at least one plate package and at least one valve is arranged to control the supply of the first fluid to the at least two injectors.
Plate heat exchanger
A plate heat exchanger includes a plate package having first and second heat exchanger plates. The plates are joined to each other and arranged side by side so that a first plate interspace exists between each pair of adjacent first and second heat exchanger plates, and a second plate interspace is formed between each pair of adjacent second and first heat exchanger plates. The first and the second plate interspaces are separated from each other and provided side by side in an alternating order. Substantially each heat exchanger plate has at least a first porthole forming a first inlet channel to the first plate interspaces. At least two injectors are arranged in a wall portion of the first inlet channel and extend from the exterior of the plate package to the first inlet channel interior, and each injector supplies a fluid to more than one of the first plate interspaces.
Evaporator fins in contact with end bracket
A refrigerator is provided with an evaporator assembly located in a compartment. The evaporator assembly includes a pipe, a fan assembly, a plurality of fins, a first and second bracket. The pipe is configured to transport a refrigerant that exchanges heat with an air stream from the compartment. The plurality of fins is inserted on the pipe. The brackets each include apertures to receive bent end portions of the pipe. The brackets are configured to hold the pipe and the fins in a specific position, to mount the evaporator assembly within the compartment, and restrict the air stream exiting the evaporator assembly from mixing with the air stream entering the evaporator assembly. The fins include end fins that are placed in direct contact with the first end bracket and are configured to further restrict the air stream from flowing through the plurality of apertures of the brackets.
Heat exchanger with thermal storage function
A cylindrical hole is formed between peripheral belt portions of two container constituent plates of a thermal storage material container of an evaporator with a cool storage function. A cylindrical portion of a thermal storage material charging member having a thermal storage material charging passage is disposed in the cylindrical hole and brazed to the two container constituent plates. That portion of the thermal storage material charging member which protrudes from the cylindrical hole includes a crushed portion and a cylindrical uncrushed portion. The crushed portion seals the thermal storage material passage. The cylindrical portion of the thermal storage material charging member is smaller in outside diameter than the uncrushed portion, and the cylindrical portion and the uncrushed portion have the same inside diameter. The cylindrical portion has an inward protrusion protruding into a thermal storage material containing space, and the inward protrusion has a radially expanding engagement portion.
SANITARY EVAPORATOR ASSEMBLY
An ice maker evaporator assembly having an evaporator pan with a back wall and left, right, top and bottom sidewalls extending from the back wall, and a freeze plate located within the evaporator pan. Refrigerant tubing is thermally coupled to the back wall of the evaporator pan opposite the left, right, top and bottom sidewalls. A first layer of insulation is formed on the refrigerant tubing.
