Abstract
The utility model discloses an energy-conserving formula heat exchanger of three channels contains a plurality of that arranges in proper order and is used for three kinds of different heat exchange gas/fluidic plate group and front and back end plate, contains board (1, 2, 3, 4) that mutually support and form three return circuits in every group, form a venturi channel between board (1) and board two (2), between board three (3) and board four (4), form a venturi channel opposite in venturi channel direction for board one (1) and board two (2) formation, between board two (2) and board three (3), form a heat-retaining medium passageway. The utility model discloses a heat exchanger structure is ingenious, and the circulation is equipped with three passageway in proper order, can make the heat of the gas-liquid of taking the waste heat that lets in at any time all by retrieving well and preserve, is particularly useful for the occasion of heat recovery with utilize the wrong time, and application range is wide, and the setting of venturi channel can let the gas-liquid pass through more smoothly, can save energy greatly from this, and the practicality is strong.
Description
Technical Field
The utility model belongs to the heat recovery field especially relates to a three channel energy-conserving formula heat exchanger.
Background
Along with the development of society, people are more and more cherishing to the energy, also want more and more high to the recovery requirement of waste heat, avoid the waste of energy, and current heat exchanger mostly exchanges between direct both sides, but this kind of mode is only suitable for online heat energy heat transfer and use basically, if the heat source utilizes one side not in the required period, heat in the heat source that has high temperature waste heat that the opposite side supplied is just can not in time be retrieved, probably only can the useless emission fall or waste.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a three-channel energy-saving heat exchanger is provided.
The utility model discloses a realize through following technical scheme:
the three-channel energy-saving heat exchanger comprises a plurality of plate groups and front and rear end plates which are sequentially arranged and used for three different heat exchange gases/fluids (A, B, C), each group comprises plates (1, 2, 3 and 4) which are mutually matched to form three loops, a Venturi channel is formed between the plate I1 and the plate II 2, a Venturi channel opposite to the Venturi channel formed between the plate I1 and the plate II 2 is formed between the plate III 3 and the plate IV 4, and a heat storage medium channel is formed between the plate II 2 and the plate III 3.
Preferably, the plates 1, 2, 3, 4 are vacuum brazed with copper as a brazing material between the plates.
Preferably, the plates 1, 2, 3, 4 are provided with a plurality of corrugations or protrusions.
The utility model has the advantages that:
the heat exchanger of the utility model has the advantages of ingenious structure, three channels are arranged in sequence in a circulating manner, the gas/liquid with the waste heat of the upper pass band can be filled in the middle layer, the gas/liquid with the waste heat of the lower pass band can be filled in the middle layer, the heat storage liquid can be filled in the middle layer, the gas/liquid with the waste heat can be well recovered and stored at any time, the heat exchanger is particularly suitable for the occasions with wrong heat recovery and utilization, the application range is wide, the heat recovery rate under the condition of asynchronous heat recovery and utilization can be greatly improved, the heat source supplement of the gas-liquid rear channel which needs to be heated is reduced, the gas-liquid can be more smoothly passed through by the Venturi type channel, the working power of the pressure pump which is used for pumping in the liquid and is arranged at the inlet of the upper, is worthy of popularization.
