Definitions
- the invention relates to an evaporator board with at least one arranged thereon Refrigerant channel, which at least one connected to a suction line outflow-side channel end section and which has at least one inflow-side, over a Capillary tube serving as a throttle with refrigerant channel end section having a refrigerant injection point formed by the capillary tube.
- the refrigerant channels according to the roll bond process or Z-bond method are produced, it is state of the art that within one to the drain-side end of a refrigerant channel covering the evaporator board connected suction pipe runs as a throttle capillary. This is over the drain-side channel end section over the inflow-side channel end section of the refrigerant channel and there by forming an injection point so-called stamping of the inflow-side channel end section on the Evaporator board fixed, with the embossing at the same time a separation between the inflow-side and thus the pressure-side area of the refrigerant channel and the discharge-side and thus suction-side area of the refrigerant channel is effected.
- the invention has for its object an evaporator board according to the Preamble of claim 1 with simple constructive measures in terms of To improve noise emissions.
- the noise level caused by the refrigerant flowing in through the injection point reduced, creating a cooling device in the living area without being bothersome and annoying the people in the living space to act can be set up, whereby the Quality of life within the living space has increased.
- the Lowering the noise level below the usual hearing threshold avoided that Incoming noise of the refrigerant is interpreted as a malfunction of the refrigeration device and customer service is unnecessarily called.
- the means as a fluidic the inflow Channel end section upstream pipe-like connector are formed, which serves to connect the capillary tube and which via elastic Connecting elements with the inflow-side channel end section and the outflow-side Channel end section is connected.
- the relocation of the injection point in the connector opens the Possibility of the cross section of the connector serving as an injection channel without Influence on the execution of the evaporator board, in particular on the design of the refrigerant channel arranged there, targeted, according to the needs To be able to choose requirements.
- the means as a fluidic the inflow Channel end section upstream, mechanically from the drain-side channel end section and fluidically decoupled connector are formed, to which the Capillary tube is connected.
- a particularly simple and in the Large-scale production is particularly reliable, with high reproducibility Achievable reduction in noise emissions because the refrigerant injection point only still via the connecting pipe serving as the injection channel with the evaporator board is connected so that those resulting from the injection process of the refrigerant Suggestions are more fully decoupled from the evaporator board.
- the tube-like connector within a in the Evaporator board recess is arranged.
- Such a design allows not only a particularly flat design for the Evaporator board but also a particularly simple manufacturing technology and reliable coupling of the capillary tube to the connector.
- the Connection point visible and thus with regard to a high quality of the Evaporator boards controllable by an inexpensive visual inspection. Further can be saved due to the recess, serving as an injection channel Connector be provided with sound-absorbing material.
- a particularly favorable decoupling of the connector serving as an injection point of the evaporator board arises if after a next advantageous Embodiment of the object of the invention is provided that the inflow side Channel end section with the connector connected to it at least over whose connection length is arranged within the recess.
- the tube-like connector is at least one frustoconical trained length section, on its smaller cross-sectional area equipped end the capillary tube is connected.
- a turbulent inflow of the Refrigerant in the connector at least largely avoided, which the Structure-borne noise on the evaporator board caused by the suggestions inflowing refrigerants are additionally reduced.
- a particularly low-noise evaporator variant results if after another preferred embodiment of the object of the invention is provided that the Capillary tube outside the drain-side channel end section the inflow-side Channel end section is supplied and fluidically connected to this.
- the capillary tube within the suction line into the The vicinity of the drain-side channel end section runs and at a distance from it led out of the suction line and connected to the connector.
- Such advantageous further training not only brings an improvement in Energy efficiency of the refrigerator, namely by pre-cooling the inside of the Suction tube running capillary tube with it, but creates through the separation the connection area of the suction pipe on the evaporator board from that of Capillary tube in a simple way a reduction of the through that The refrigerant flowing in the capillary tube causes the injection noise.
- the capillary tube is guided along the outer surface of the suction line and is connected to the connector.
- An evaporator board can be operated particularly quietly if after a last preferred embodiment of the subject of the invention provided is that at least the inflow-side channel end section and that for connecting the Capillary tube serving connector is embedded in soundproofing material.
- FIG. 1 is a simplified schematic representation Evaporator board 10 shown, which has a meandering on its surface extending, for example manufactured in the Rollbond or Z-Bond process Has refrigerant channel 11. This has a two-way flow technology connected to it and led up to the edge of the evaporator board 10 drain-side channel end section 12, which for connecting a liquid and gas-tight within the flow cross section of the channel end section 12 fixed suction pipe 13 is used.
- the channel end section 19 is, for example, made of aluminum or copper or The same manufactured tubular connector 20 liquid and connected gastight.
- the tubular connector 20 has a for coupling to the channel end section 19 serving section 21 with parallel extending surface lines and an adjoining section 22, which in Type of a truncated cone is formed.
- With the section 22 is the end section 15 of the capillary tube 14 liquid and gas-tight connection, whereby an inside the connector 22 arranged injection point 23 for within the Capillary tube 14 flowing refrigerant is created.
- FIG. 2 shows a second embodiment of an inventive Evaporator board 30, which like the evaporator board 10 is at least one extending approximately meandering over its surface, for example in Rollbond or Z-bond method generated refrigerant channel 31.
- This has an inflow-side arranged in the upper third of the evaporator plate 30 Channel end portion 32, the free end one into a tubular Connecting piece 33 receiving section 34, the connecting piece 33 in the present case is in the form of a circular hollow cylinder.
- the connector 33 has a truncated cone Section 35 on. This is within a drain end section 36 Serving channel piece of the refrigerant channel 31 arranged, which for receiving of the frustoconical section 35 one with its free end Has channel section 32 facing connection piece 37.
- connection section 38 is provided.
- annular connecting element 39 which, on the one hand, seals against the channel wall of the connecting piece 37 or the channel end section 32 and on the other hand sealing to the jacket side of the Connector 33 creates.
- the connector 33 is the smaller one End of its truncated cone-like section 35 having a cross-sectional area with one serving as a throttle and belonging to a capillary tube 40 End portion 41 connected liquid and gas tight, the end portion 41 for Formation of a refrigerant injection point 42 in the frustoconical section 35 protrudes.
- the capillary tube 40 which is inside the drain-side channel end portion 36 is guided from its connecting piece 37 to its connecting section 38, runs outside of the evaporator board 30 within a liquid and gas tight connected to the connection section 38 suction pipe 43, whereby the capillary 40 cooled down to improve the energy efficiency of the refrigerant circuit is.
