A plate package made according to the method includes first heat exchanger plates and second heat exchanger plates. Each heat exchanger plate has a first porthole, and the port hole of at least one of the heat exchanger plates is surrounded by a peripheral rim. The first heat exchanger plates and the second heat exchanger plates, are joined to each other and arranged side by side in such a way that the peripheral rims together define an inlet channel extending through the plate package. The peripheral rim of the first and/or the second heat exchanger plates has at least one through hole, forming a fluid passage allowing a communication between the inlet channel and the first plate interspaces. The at least one through hole is made in a condition in which the first and the second heat exchanger plates have been joined to each other to form the plate package.

Method of making a plate package for a plate heat exchanger

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.

System and method for dynamic control of an evaporator

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.

Plate heat exchanger

The invention relates to a plate heat exchanger () having a package of heat transfer plates (), which are provided with through inlet ports () forming an inlet channel () through the package, and between the heat transfer plates arranged sealing means, which together with the heat transfer plates in every other plate interspace delimit a first flow passage () for one fluid and in each of the remaining plate interspaces delimit a second flow passage () for a second fluid, wherein the inlet channel () communicates with each first flow passage () by way of a first inlet passage (), and is sealed from communication with each second flow passage by the sealing means.
