Abstract
The invention provides a heat tube type heat exchanger with a good heat exchange effect. The heat tube type heat exchanger is composed of a hollow tube allowing a liquid at a first temperature to flow through and a heat exchange tube allowing a liquid at a second temperature to flow through. The heat exchange tube is located in the hollow tube. The key is to arrange spoilers in the heat exchange tube; each spoiler is cambered; one end of each spoiler is fixedly connected with an inner wall of the heat exchange tube, while the other end of each spoiler is bent in a direction of a central axis of the heat exchange tube; a nick is formed in the middle of the free end of each spoiler, and the end portions, on the two sides of the nick, of each spoiler are bent in different directions. When the liquid at the second temperature flows in the heat exchange tube, the liquid is blocked and guided by the spoilers, and part of the liquid flows in the direction of the central axis of the heat exchange tube, leading to the fact that the original liquid at the central axis of the heat exchange tube spreads around; in this way, own heat exchange of the liquid in the heat exchange tube is accelerated, such that the temperature of the liquid in the heat exchange tube trends to be uniform; and therefore, the defects of non-uniform temperature and bad heat exchange effect of the liquid in the traditional heat exchange tube are overcome.
Description
Technical field
The invention belongs to refrigeration technology field, be specifically related to the heat exchanger that a kind of air-conditioning uses.
Background technology
Heat exchanger is used to make heat be delivered to cold flow body from hot fluid, device with the technological requirement of satisfied regulation, it is a kind of commercial Application of convection heat transfer' heat-transfer by convection and conduction of heat, and in heat exchanger, the modal inside and outside heat of heat pipe that is through exchanges and realizes heat exchange purpose hot-pipe type heat-exchanger.In traditional hot-pipe type heat-exchanger, the liquid only pressing close to heat pipe inner surface just easily realizes heat exchange, and the heat exchange effect of the liquid of heat pipe central authorities is poor, how to improve the heat exchange effect of entirety, is the direction of engineers design.
Summary of the invention
The purpose of the present invention is to propose to the hot-pipe type heat-exchanger that a kind of heat exchange effect is good.
The hot-pipe type heat-exchanger of the present invention is by the hollow pipe flow through for the first temperature liquid and the heat exchanger tube flow through for the second temperature liquid, described heat exchanger tube is positioned at hollow pipe, it is critical only that in described heat exchanger tube and be provided with spoiler, described spoiler is arc, one end of spoiler is fixing with the inwall of heat exchanger tube to be connected, and the other end bends to the direction, axis of heat exchanger tube；It is provided with breach in the middle part of the free end of spoiler, and the bending direction of the spoiler end of breach both sides is different.
Second temperature liquid is when heat exchange Bottomhole pressure, its obstruction being subject to spoiler and guiding, partially liq flows to the direction, axis of heat exchanger tube, originally the liquid being in the axis place of heat exchanger tube is spread to surrounding, thus accelerate the heat exchange of heat exchange liquid in pipe self, temperature of liquid in heat exchanger tube is reached unanimity, changes the drawback that the temperature of liquid in traditional heat-exchange tube is uneven, heat exchange effect is poor.Owing to being provided with breach in the middle part of the free end of spoiler, and the bending direction of the spoiler end of breach both sides is different, when liquid flows through the free end of spoiler, can produce the little eddy current consistent with the direction, axis of heat exchanger tube, accelerate the mixing of liquid.
Further, described spoiler has a multi-disc, and straggly is distributed in heat exchanger tube, so that the liquid flowing in heat exchanger tube is in unordered shape, makes the temperature of liquid in heat exchanger tube reach unanimity.
Further, in order to conveniently install spoiler, the inwall of described heat exchanger tube is provided with female thread, and described spoiler is installed in annulus, and the lateral surface of described annulus is provided with and the external screw thread of described screw-internal thread fit, and described annulus is installed in heat exchanger tube by threaded engagement.The hot-pipe type heat-exchanger of the present invention, by arranging the spoiler that structure is unique, easy for installation, improves the situation that the temperature of liquid in heat exchanger tube is uneven, thus improve the effect of heat exchange.

Accompanying drawing indicates: 1, hollow pipe；2, heat exchanger tube；3, spoiler；31, the spoiler on the left of breach；32, the spoiler on the right side of breach；4, annulus.
Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, the effect and operation principle etc. of the mutual alignment between the such as involved shape of each component of the specific embodiment of the present invention, structure, each several part and annexation, each several part is described in further detail.
Embodiment 1:
As shown in the figure, the hot-pipe type heat-exchanger of the present embodiment is by the hollow pipe 1 flow through for the first temperature liquid and the heat exchanger tube 2 flow through for the second temperature liquid, described heat exchanger tube 2 is positioned at hollow pipe 1, it is critical only that in described heat exchanger tube 2 and be provided with spoiler 3, described spoiler 3 is arc, one end of spoiler 3 is fixing with the inwall of heat exchanger tube 2 to be connected, and the other end bends to the direction, axis of heat exchanger tube 2；It is provided with breach in the middle part of the free end of spoiler 3, and the bending direction of spoiler 3 end of breach both sides is different, in the present embodiment, the spoiler 31 on the left of breach bends to the inwall direction of heat exchanger tube 2, and the spoiler 32 on the left of breach bends to the direction, axis of heat exchanger tube 2.
Further, described spoiler 3 has a multi-disc, and straggly is distributed in heat exchanger tube 2, so that the liquid flowing in heat exchanger tube 2 is in unordered shape, makes the temperature of liquid in heat exchanger tube 2 reach unanimity.
Further, installing spoiler 3 in order to convenient, the inwall of described heat exchanger tube 2 is provided with female thread, and described spoiler 3 is installed in annulus 4, the lateral surface of described annulus 4 is provided with and the external screw thread of described screw-internal thread fit, and described annulus 4 is installed in heat exchanger tube 2 by threaded engagement.
When second temperature liquid flows in heat exchanger tube 2, its obstruction being subject to spoiler 3 and guiding, partially liq flows to the direction, axis of heat exchanger tube 2, originally the liquid being in the axis place of heat exchanger tube 2 is spread to surrounding, thus accelerate the heat exchange of liquid self in heat exchanger tube 2, temperature of liquid in heat exchanger tube 2 is reached unanimity, changes the drawback that the temperature of liquid in traditional heat-exchange tube is uneven, heat exchange effect is poor.Owing to being provided with breach in the middle part of the free end of spoiler 3, and the bending direction of spoiler 3 end of breach both sides is different, when liquid flows through the free end of spoiler 3, can produce the little eddy current consistent with the direction, axis of heat exchanger tube 2, accelerate the mixing of liquid.
