Abstract
The invention discloses a kind of direct heat transfer plate heat exchanger, there is thermal-insulated frame on plate heat exchanger periphery；Plate heat exchanger is combined into by two panels heat exchanger plates, has to form the depression of runner, connecting tube connecting passage on heat exchanger plates, and refrigerant passes in and out runner by connecting tube；Ice can only be formed in thermal-insulated frame side during ice making, and when deicing, it is water that the ice heat absorption for the plate surface that exchanges heat, which is melted, and plate ice loses viscosity, releases the ice cube in heat exchange plate face, and the present invention is simple in construction, heat transfer efficiency is high, cost Low investment is small, power consumption is few.
Description
Technical field
The present invention relates to refrigeration technology field, especially a kind of direct heat transfer plate heat exchanger.
Background technology
At present, ice making heat exchanger used in plate ice machine is mainly indirect heat transfer plate heat exchanger, and the cold of refrigerant evaporation must
Two layer materials must be passed through（Refrigerant flow path tube wall and heat exchanger plates）One of contact surface, made from refrigerant flow path outer surface by contact
Cold is passed to ice making heat exchanger plates by ice heat exchanger plates inner surface, and ice is formed on the outer surface of ice making heat exchanger plates.It is such indirect
Heat transfer should overcome the thermal resistance of refrigerant flow path, overcome the thermal resistance of surface loose contact again, heat transfer efficiency is low, and material
Dosage is more, and cost is high.Therefore prior art has much room for improvement and developed.
The content of the invention
The technical problem to be solved in the present invention is：It is high to provide a kind of heat transfer efficiency, material usage is few, the low direct biography of cost
Hot plate piece heat exchanger.
The present invention technical solution be：A kind of direct heat transfer plate heat exchanger, including it is heat exchanger plates, connecting tube, heat-insulated
Frame；The plate heat exchanger is combined into by two panels heat exchanger plates, can use viscous, weldering, hot pressing connects, ensures the plate heat exchange
The intensity of device and the seal of runner, the heat exchanger plates are using the good sheet material of heat conduction（Such as copper aluminium titanium stainless steel）Pressure
System, described heat exchanger plates are symmetrical, have to form the depression of runner on the heat exchanger plates, and the runner of the plate heat exchanger is exactly
Formed by the depression on the heat exchanger plates, connecting tube connects the runner on the heat exchanger plates, and refrigerant passes through the connection
Pipe passes in and out the runner on the plate heat exchanger；There is thermal-insulated frame on the plate heat exchanger periphery, and the thermal-insulated frame is using poly-
Compound expanded material is molded, and ice can only be formed in the thermal-insulated frame, and what one side was bonded in the thermal-insulated frame side described changes
On hot plate outer surface, hydrophobic processing is done in the outer surface of the heat exchanger plates.Refrigerant passes in and out the plate by the connecting tube and changed
The runner on hot device, the low pressure refrigerant liquid flowed into during ice making evaporate suction in the runner of the plate heat exchanger
Heat, gasification outflow, water freezes on the heat exchanger plates outer surface in the thermal-insulated frame of the plate heat exchanger, setting when
Between after, certain thickness plate ice is formed on the outer surface of the heat exchanger plates；Now plate ice machine, which automatically begins to enter, deices pattern, flows
The higher pressure refrigerant gas entered condenses heat release in the runner of the plate heat exchanger, and liquefaction is flowed out, the heat exchange plate surface
It is water that ice heat absorption, which is melted, and plate ice loses viscosity, releases the ice cube in the heat exchange plate face；The plate ice machine automatically begin to again into
Enter ice-make mode.The plate heat exchanger can also be applied to refrigerator or other heat exchange, ice makers.
The beneficial effects of the invention are as follows：Heat transfer efficiency is high, and material usage is few, and cost is low.
