Abstract
The utility model relates to a plate and tube heat exchanger which is capable of eliminating heat transfer resistance between a heat transfer plate and heat transfer tubes and improving the heat transfer effect of the plate and the tubes. The heat transfer plate and the heat transfer tubes of the plate and tube heat exchanger are made into one body. The plate and tube heat exchanger is composed of the heat transfer plate and two heat transfer circular tubes under the heat transfer plate, wherein the heat transfer plate and the circular tubes are cast into one body and are tightly connected so as to form the plate and tube heat exchanger. Due to the tight combination mode of the heat transfer plate and the circular tubes, the heat transfer resistance between the plate and the tubes is decreased. When the plate and the tubes carry out heat exchange, heat is directly mutually transferred and conducting ability and heat exchange efficiency are improved.
Description
Technical field
The utility model relates to heat-exchange device, is specifically related to a kind of tube-on-sheet heat exchanger that can improve heat exchanger effectiveness.Belong to International Classification of Patents F28F3/00 " parts---the tabular or lamination element of interchangeable heat exchange or heat-transfer equipment " technical field.
Background technology
In the prior art, the heat transfer plate and the heat-transfer pipe of tube-on-sheet heat exchanger are generally all constituted by two parts, and these two parts are in heat conducting process, because it is bad to coincide, cause thermal resistance to increase, and heat transfer efficiency descends.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of heat transmission resistance that can eliminate between heat transfer plate and the heat-transfer pipe is provided, and improves the tube-on-sheet heat exchanger of heat-transfer effect between plate and the pipe.
The purpose of this utility model is achieved through the following technical solutions.
The heat transfer plate and the heat-transfer pipe of tube-on-sheet heat exchanger are made the all-in-one-piece structure, that is: tube-on-sheet heat exchanger, form by heat transfer plate and two circular heat-transfer pipes being provided with below thereof, two pipes that this heat transfer plate and its are provided with below are cast into one, closely connect, form tube-on-sheet heat exchanger.
Described heat transfer plate can be flat board or concave-board.The width of flat board or concave-board and thickness can be decided according to the actual requirements.The size of pipe and thickness can be decided according to the actual requirements.
The utility model is because into a single integrated structure with the plate and the pipe making of tube-on-sheet heat exchanger, and heat transfer plate and heat-transfer pipe are that casting becomes one with a kind of material.It is combined closely and has reduced heat transmission resistance between plate and the pipe, and when plate and pipe carried out heat exchange, heat directly transmitted mutually, has improved conducting power and heat exchanger effectiveness.Greatly reduce the energy loss that causes owing to the heat-transfer effect difference in actual use.
Description of drawings
Fig. 1 is the structural representation of the tube-on-sheet heat exchanger of the utility model plane template;
Fig. 2 is the structural representation of the tube-on-sheet heat exchanger of the utility model groove template.
Among the figure: 1, heat transfer plate, 2, heat-transfer pipe.
The specific embodiment
As shown in Figure 1, in this tube-on-sheet heat exchanger, adopt plane template 1, be provided with two pipes 2 below dull and stereotyped 1, flat board 1 is to become one through special processing casting with pipe 2.It forms a carriage, has strengthened the contact area with planar object.
As shown in Figure 2, in this tube-on-sheet heat exchanger, adopt groove template 1, below the concave-board 1, be positioned at symmetrical position, groove both sides and be provided with two pipes 2, concave-board 1 is the semicircle that forms arc through special processing casting, then with pipe 2 cast solids.This tube-on-sheet heat exchanger has strengthened the contact area with circular object, is convenient to circular article moulding, has improved heat transfer efficiency simultaneously, has reduced energy consumption.
Claims (2)
1, a kind of tube-on-sheet heat exchanger is made up of heat transfer plate and two heat transfer pipes being provided with below thereof, and it is characterized in that: described heat transfer plate closely is connected, is cast into one with two pipes that it is provided with below.
2, tube-on-sheet heat exchanger according to claim 1 is characterized in that: described heat transfer plate can be flat board or concave-board.
