Description

Divided flow combined evapourator for freezer

The utility model relates to a kind of heat exchanger of refrigeration plant, specifically a kind of shunting combination ice chest evaporator.

The evaporimeter of present commercially available refrigerator-freezer is single closed circuit, it is cold-producing medium only enters an aluminum behind capillary evaporator pipeline, the evaporimeter refrigerating speed of this structure is slow, and because of making evaporimeter with aluminum pipe, so pipeline easily is corroded and bores a hole, the outside seepage of cold-producing medium causes refrigerator-freezer forfeiture refrigerating function.This evaporimeter and refrigerating chamber are an integral body in addition, during maintenance, and not only dismounting difficulty, and to destroy insulating foam layer, and increased the repairing difficulty, also improved the cost of repairs.

It is fast that the purpose of this utility model provides a kind of refrigerating speed, and maintenance is easy to the refrigerator-freezer refrigerating evaporator.

The utility model is achieved like this adopts the knockdown evaporimeter of shunting, and this evaporimeter comprises two groups of evaporation plate, isocon and collecting pipes of constituting the closed circuit of symmetry.Evaporation plate then is the one piece member that is made of coiled pipe and support side's plate, is diverted to by isocon in two groups of evaporation plate through the cold-producing medium of bundle of capillary tubes, by collecting pipe cold-producing medium is back to the compressor from two groups of evaporation plate then.The flow through length of pipeline loop of the cold-producing medium of this evaporimeter has only half of former evaporimeter loop total length, thereby flows through the loop required time and also shorten half, and refrigerating speed improves greatly.Two groups of evaporation plate and freezer compartment wall are not integral, thereby when maintenance dismounting easily, do not destroy heat-insulation layer yet, every group of evaporation plate can be made up of two or more than two evaporation plate, when evaporation plate when forming more than two, coiled pipe between the evaporation plate can connect with tube connector, other shape that one-tenth square shape capable of being combined, door font, river font or refrigerator-freezer require.What and of size, the shape decision of big I of every group of evaporation plate by refrigerator-freezer.The evaporation plate of this segmented also helps maintenance, when which section coiled pipe has perforation, as long as the evaporation plate of this section is changed, and needn't change whole evaporation plate.Can reduce the cost of repairs greatly.

By Fig. 1-3 as seen, evaporimeter of the present utility model comprises

evaporation plate

1,2, isocon 3 and the collecting pipe 4 of two groups of symmetries.

Evaporation plate

1,2 includes coiled pipe 6 and gripper shoe 7, and isocon 3 is made up of skirt and two arms, and its skirt is connected with capillary, and two arms are connected with refrigerant inlet 8, the 8 ' (see figure 6) of two groups of

evaporation plate

1,2 coiled pipe 6 respectively. Collecting pipe 4 is made up of skirt and two arms, and its skirt and compressor loop are connected, the two arms (see figure 6) that is connected with the refrigerant outlet 9,9 ' of two groups of

evaporation plate

1,2 coiled pipe 6 respectively. Every group of evaporation plate can be made up of two or more than two evaporation plate. Can connect by tube connector 5 between two evaporation plate.

Evaporation plate

1 or 2 coiled pipe 6 can be integrated with support side's plate 7 or coiled pipe 6 is bonded on support side's plate 7 (sees Fig. 4,5). Corrosion-resistant for evaporimeter, increase the service life. Coiled pipe 6 can be made of copper material. The evaporimeter that assembles, be installed to refrigerating chamber after, be not integral with heat-insulation layer, dismounting easily, be convenient to maintenance, do not destroy heat-insulation layer yet, can greatly save maintenance time and expense.

Therefore evaporimeter refrigerating speed of the present utility model is fast; Processing and easy to maintenance, reduced maintenance time and expense, evaporation tubes is more corrosion-resistant, has increased service life, is convenient to packed and transported and depositing.

Embodiment, present embodiment are the square shape evaporimeter, and its planar development is seen Fig. 6.

This evaporimeter is made up of two groups of evaporation plate, and every group of evaporation plate has small one and large one two evaporation plate, and its label is 1A, 1B for 1 group, and 2 groups is 2A, 2B.The coiled pipe of evaporation plate and support side's plate are not one, and coiled pipe is made into the semi-circular section (see figure 5) with copper pipe and is bonded on support side's plate.Serpentine type arrangement on two groups of evaporation plate is symmetrical, so that when isocon is connected with it with collecting pipe, the shortest distance (see Fig. 6, use isocon, the collecting pipe of T font to get final product) can be arranged, the coiled pipe interface on two evaporation plate of 1A, 1B 10,11 is communicated with tube connector 5; With tube connector 5 ' the coiled pipe interface on two evaporation plate of 2A, 2B 10 ', 11 ' is communicated with.Use isocon 3 that the refrigerant inlet 8,8 ' of the coiled pipe of 1B, 2A evaporation plate is joined then, the refrigerant outlet 9,9 ' of the coiled pipe of 1A, 2B evaporation plate is connected with collecting pipe 4.This has just constituted the square shape shunting combined evaporimeter with two symmetrical circuits basically.The marginal portion on evaporimeter top (behind the refrigerator-freezer of promptly packing into outwardly an end) will be pressed into flange 12, flange is 15 millimeters, and become 135 degree angles with the evaporation plate plane, to increase gripper shoe intensity, improve the outward appearance of repairing the back refrigerator-freezer.

When ice chest evaporator is installed, need only bore the open-work that diameter equates with the skirt external diameter by the position of refrigerator-freezer wall at the isocon skirt, equally also bore an open-work that equates with this skirt external diameter outside by refrigerator-freezer cabinet wall at the collecting pipe skirt, two skirts are passed open-work respectively, be connected with muffler with the air inlet pipe of cooling cycle system outside cabinet, the evaporimeter of refrigerator-freezer is a successful installation.During reparation, as long as dismantle, and needn't the wall of whole freezing chamber be destroyed, and can repair, avoided transportation in the original place having gone bad parts accordingly.
