Abstract

A thin plate heat exchanger which belongs to the heat exchange devices, in particular to a thin plate heat exchanger formed by laminated channels comprises a shell body and is characterized in that the middle of the shell body is provided with a layer of pipe coil cold water channel formed by welding a pipe coil slot plate and a flat thin plate, and the upper surface and the lower surface of the cold water channel are respectively provided with a layer of hot water channel formed by the pipe coil slot plate. The utility model can be used in various heat exchanging situations and is especially suitable for the heat utilization of the waste hot water of household showers.

Description

Thin plate heat exchanger

Technical field:

The utility model belongs to a kind of heat-exchanger rig, particularly the Thin plate heat exchanger that is made of the lamination passage.

Background technology:

No. 98202907.1, Chinese patent disclosed " demountable panel shell heat exchanger " is per two ripples to be spun plate be welded into one group, forms a runner, two groups of plate assemblings, makes to form another runner again between two groups of plates again, organizes plate more and forms a complete machine.Though this heat exchanger can bear high temperature, high pressure, need per two plates are welded into one group, the technology relative complex.

Summary of the invention:

The purpose of this utility model is to provide a kind of a coil-like frid and Zhang Ping's thin plate is welded into one group, forms a cold water channel; Again thereon, a coil-like thin plate is respectively put on the two sides down, constitutes two hot water channels' Thin plate heat exchanger up and down.

The utility model comprises housing, it is characterized in that the coil-like cold water channel that the centre in housing has one deck to be formed by coil-like frid and dull and stereotyped weldering system, and cold water inlet is located at the outer rim of coil-like cold water channel, and cooling water outlet is located at the central authorities of coil-like cold water channel; Upper and lower faces at coil-like cold water channel, the coil-like hot water channel who respectively has one deck to constitute by coil-like frid, hot water inlet is located at the central authorities on Thin plate heat exchanger upper strata, and penetrating housing and upper strata hot water channel's coil-like frid, outlet is located at upper and lower two-layer coil-like hot water channel's outer rim; In the central authorities of coil-like cold water channel, be provided with a communicating pipe of passing cold water channel and being communicated with upper and lower two-layer hot water channel.

The utility model can be used for various heat exchange occasions, during especially for domestic hot water's shower, be thermal source, the cold water of sending water heater to is carried out heat exchange with it earlier in the utility model with the waste water after the shower, send the water heater heating after the preheating again to, then can reach the energy of saving more than 70%.

Description of drawings:

Accompanying drawing 1 is a cutaway view of the present utility model.

Accompanying drawing 2 is the coil-like frids that use when making the utility model;

Among the figure: the 1-housing; The 2-hot water channel; The 3-cold water channel; The coil-like frid of 4-; The 5-hot water inlet; The 6-cooling water outlet; 7-communicating pipe; The 8-cooling water inlet; The 9-hot water outlet; The 10-isolation channel; The 11-heat-insulation layer.

The specific embodiment:

Weld jointly with a flat thin plate earlier and make coil-like cold water channel 3, establish a cooling water inlet 8, establish a cooling water outlet 6 in the central authorities of coil-like cold water channel 3 in the outer rim of coil-like cold water channel 3 with a coil-like frid 4 as shown in Figure 2; Respectively put a coil-like frid 4 at the upper and lower faces of cold water channel 3 again, constitute upper and lower two-layer hot water channel 2, the central authorities with upper and lower two-layer hot water channel are communicated with the communicating pipe 7 of passing cold water channel 3; With housing 1 cold water channel itself and upper and lower two-layer hot water channel are fixed in the housing 1 again, intermediate open position hot water inlet 5 on housing 1, obviously, hot water inlet 5 should penetrate housing and upper strata hot water channel's coil-like frid, and the outer rim place in the side of housing 1 corresponding to upper and lower coil-like hot water channel opens a hot water outlet 9.During use, hot water is from hot water inlet 5 and enter communicating pipe 7 the upper and lower two-layer hot water channel 2, is revolving to outflow from telophragma; Cold water then enters cold water channel from cooling water inlet 8 and is spiraling toward center stream, discharges from cooling water outlet 6 at last to be used.Coil-like frid 4 among the figure also can be circle, rectangle, ellipse etc. for being square, and the isolation channel 10 on it both can play the current deflecting effect, can play reinforcement again.Isolation channel 10 is generally trapezoidal cross-section, its upper base 2mm, and the 4mm that goes to the bottom, trapezoidal high 4mm, the distance between two grooves is best with 18mm.Certainly, the section of isolation channel 10 also can make other shapes, and its size and spacing also can change.In order to improve efficient of the present utility model, be preferably between upper and lower two-layer hot water channel 2 and the housing 1 and add one deck insulation material 11.When being added with insulation material 11, hot water inlet 5 also should penetrate insulation material 11.

Claims

1, a kind of Thin plate heat exchanger, comprise housing, it is characterized in that: the coil-like cold water channel that the centre in housing has one deck to be formed by coil-like frid and dull and stereotyped weldering system, cooling water inlet is located at the outer rim of coil-like cold water channel, and cooling water outlet is located at the central authorities of coil-like cold water channel; Upper and lower faces at coil-like cold water channel, the coil-like hot water channel who respectively has one deck to constitute by coil-like frid, hot water inlet is located at the central authorities on Thin plate heat exchanger upper strata, and penetrating housing and upper strata hot water channel's coil-like frid, hot water outlet is located at upper and lower two-layer coil-like hot water channel's outer rim; In the central authorities of coil-like cold water channel, be provided with a communicating pipe of passing cold water channel and being communicated with upper and lower two-layer hot water channel.
