Description

Anti-bias regenerative heat exchanger and use the air-conditioner of this heat exchanger

Technical field

This utility model belongs to air-conditioner field, particularly relates to a kind of anti-bias regenerative heat exchanger and uses the air-conditioner of this heat exchanger.

Background technology

Air conditioning system maker is in terms of heat exchanger diversion design at present, all uses traditional centrifugal diversion design, makes the feeder number passed through equal the most as far as possible or divide equally loop according to stress test, and the pipeline handing over allotter to be connected with heat is L-shaped single-pipeline.In addition to equal locellus (interior) exterior-heat is handed over, each branch import add different capillary tube regulation coolant quantity number.Due to terrestrial gravitation and the acceleration of gravity of coolant itself, multichannel can be caused when distributing, to flow to the coolant of arm outside allotter many, flow to the coolant inside allotter few, the coolant quantity causing each road differs greatly, cause distribution inequality, the each road that can not make heat exchanger carries out sufficient heat exchange, causes capacity loss.In addition to equal locellus (interior) exterior-heat is handed over, each branch import add different capillary tube regulation coolant quantity number, so can cause power rise, and noise (in especially, coolant flow noise occurs in machine) easily occurs.Being embodied in air conditioner aspect, may cause ability step-down, power becomes big, and efficiency is deteriorated then.

Utility model content

This utility model, for the technical problem of existing heat exchanger coolant branch road distribution inequality, proposes a kind of heat exchanger with T-shaped pipeline, and coolant forms eddy current in T-shaped pipeline, can make heat exchanger shunting uniformly, prevent the centrifugal force that coolant gravity produces.Without additional capillary tube, just can make the coolant distributed uniform of heat exchanger, reach good heat transfer effect.

In order to achieve the above object, the technical solution adopted in the utility model is:

A kind of anti-bias regenerative heat exchanger, hands over fin, some hair fastener pipes to connect composition coolant loop including flowing into arm, allotter, hair fastener pipe and heat.Being connected between described inflow arm and allotter and have T-shaped pipeline, described T-shaped pipeline includes VERTICAL TUBE and horizontal tube, and described horizontal tube one end connects inflow arm, and the other end seals, and seal is circular arc；Described VERTICAL TUBE connects allotter.

As preferably, flow into branch pipe welding on one end inwall of horizontal tube.

As preferably, VERTICAL TUBE plugs the side to horizontal tube, and stretches to inside horizontal tube.

As preferably, VERTICAL TUBE and horizontal tube are 90 ° and are welded to connect.

This utility model additionally proposes a kind of air-conditioner, including compressor, heat exchanger, fluid reservoir,.Described heat exchanger includes that flowing into arm, allotter, hair fastener pipe and heat hands over fin, some hair fastener pipes to connect composition coolant loop.Being connected between described inflow arm and allotter and have T-shaped pipeline, described T-shaped pipeline includes VERTICAL TUBE and horizontal tube, and described horizontal tube one end connects inflow arm, and the other end seals, and seal is circular arc；Described VERTICAL TUBE connects allotter

Compared with prior art, advantage of the present utility model and having the active effect that

Heat exchanger described in the utility model, vortex is formed when coolant circulates in T-shaped pipeline, effectively reduce inertia and centrifugal force, make the centrifugal force that air conditioning chamber's (interior) outer machine heat prevents coolant gravity from producing when handing over shunting, without additional capillary tube, just can make the coolant distributed uniform of heat exchanger, reach good heat transfer effect.The end of horizontal tube is set to circular arc simultaneously, makes the coolant distribution confluxed more uniform, and the buffering effect of coolant is more preferable.Can also effectively reduce coolant gas-liquid separation, effectively reduce the noise that coolant flow noise produces.Due to shunting uniformly, high pressure is relatively low for air-conditioner, can effectively reduce the complete machine acc power of this air-conditioner, improve complete machine capability.

Detailed description of the invention

In order to be better understood from this utility model, illustrate with embodiment below in conjunction with the accompanying drawings.

In description of the present utility model, it should be noted that, " bottom " " top " in described circuit system " etc. the orientation of instruction or position relationship be based on position relationship shown in the drawings; being for only for ease of description this utility model and simplifying describes; rather than instruction or imply the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.

Example: as shown in Figure 1 and Figure 2, a kind of anti-bias regenerative heat exchanger, hand over fin 4 including flowing into arm 1, allotter 2, hair fastener pipe 3 and heat.Some hair fastener pipes 3 connect arrangement through u shaped connector, form multiple coolant loop, are provided with heat and hand over fin 4, increase heat exchange area outside coolant loop.Being connected between described inflow arm 1 and allotter 2 and have T-shaped pipeline 5, described T-shaped pipeline 5 includes VERTICAL TUBE 51 and horizontal tube 52, and described horizontal tube 52 one end connects inflow arm 1, and the other end seals, and sealing end is circular arc；Described VERTICAL TUBE 51 top connection allotter 2, allotter top connects each coolant branch road 6.With reference to Fig. 3, coolant flows through T-shaped pipeline 5 through flowing into arm 1, enters each coolant loop, carry out heat exchange after the distribution of the most the allocated device 2.A vortex is formed when coolant circulates in T-shaped pipeline 5, effectively reduce inertia and centrifugal force, make air conditioning chamber's (interior) outer machine heat hand over the centrifugal force that shunting prevents coolant gravity from producing, it is not necessary to add capillary tube, just can make the coolant distributed uniform of heat exchanger, reach good heat transfer effect.The end of horizontal tube 52 is set to circular arc simultaneously, makes the coolant distribution confluxed more uniform, and the buffering effect of coolant is more preferable.Can also effectively reduce coolant gas-liquid separation, effectively reduce the noise that coolant flow noise produces.

Fig. 4 is the T-shaped pipeline of this utility model 5 and allotter 2 connection figure.As described in Figure 4, flow into arm 1 and be welded on one end inwall of horizontal tube 52, use the form of welding so that flow into the connection between arm 1 and horizontal tube 52 tightr, improve sealing.VERTICAL TUBE 51 preferably plugs the side to horizontal tube 52, and it is internal to stretch to horizontal tube 52, and VERTICAL TUBE 51 then uses with the outside of the junction of horizontal tube 52 and welds, and the most preferably improves sealing.

This utility model additionally proposes a kind of air-conditioner using above-mentioned heat exchanger, and due to shunting uniformly, high pressure is relatively low, can effectively reduce the complete machine acc power of this air-conditioner, improving complete machine capability, in response to national energy-saving policy, this design can be widely applied to develop high-efficiency and energy-saving type air-conditioning.

The above; it it is only preferred embodiment of the present utility model; it it is not the restriction that this utility model is made other form; any those skilled in the art are changed possibly also with the technology contents of the disclosure above or are modified as the Equivalent embodiments of equivalent variations is applied to other field; but it is every without departing from technical solutions of the utility model content; any simple modification, equivalent variations and the remodeling made above example according to technical spirit of the present utility model, still falls within the protection domain of technical solutions of the utility model.
