Abstract
The utility model discloses thermocouple good heat dissipation performance, comprising in sequence from a cold end to a hot end: a junction box having lead terminals, an upper protective sleeve and a measurement protective sleeve; a hole cavity of the measurement protective sleeve is provided with a temperature measurement element; a heat dissipation element is arranged between the upper protective sleeve and the measurement protective sleeve; and the center of the heat dissipation element is provided with an inner hole which is communicated with the hole cavity of the measurement protective sleeve. Compared with the structure of traditional thermocouple, the thermocouple in the utility model can achieve excellent heat dissipation effects without lengthening the length of the upper protective sleeve.
Description
Technical field
The utility model belongs to temperature instrumentation structural design field, is specifically related to a kind of thermopair of perfect heat-dissipating.
Background technology
Thermopair as a kind of temperature instrumentation have that measuring accuracy is high, measurement range is wide, advantages of simple structure and simple.The thermopair in use high temperature place in petroleum chemical industry often need to be measured the temperature more than 1000 ℃.When thermopair operation work, heat can be delivered to upper protective casing from the measuring and protecting sleeve pipe and be delivered to terminal box again.Yet according to requirement of explosion proof regulation, when the temperature of terminal box surpasses 60 ℃, do not reach in some aspects requirement of explosion proof, the situation such as the temperature transmitter in the terminal box also can highly occur that accessory is aging because of temperature simultaneously, distortion, measurement data are inaccurate.In order to reduce the temperature of terminal box, the modal way that present client takes is the length that prolongs upper protective casing, adopts this way the length that installing space does not satisfy thermopair can occur, the situation that causes thermopair to install; If the thermo wires of thermopair adopts noble metal, along with the increase of upper protective casing length, cost also increases thereupon so.
The utility model content
For the deficiency that exists on the existing thermocouple structure, the utility model provides a kind of length that need not prolong upper protective casing also can reach the thermopair of good radiating effect.
The technical scheme that realizes the utility model purpose is:
A kind of thermopair of perfect heat-dissipating comprises from the cold junction to the hot junction successively: have the terminal box of lead terminal, upper protective casing and measuring and protecting sleeve pipe; In the vestibule of described measuring and protecting sleeve pipe, be provided with temperature element;
Be provided with heat dissipation element between described upper protective casing and the measuring and protecting sleeve pipe; Described heat dissipation element center is provided with the endoporus with the vestibule UNICOM of measuring and protecting sleeve pipe.
In the technique scheme, the outer wall of described measuring and protecting sleeve pipe is provided with mounting flange or external thread.
In the technique scheme, described mounting flange is welded on the described measuring and protecting sleeve pipe.
In the technique scheme, described terminal box and described upper protective casing welding.
In the technique scheme, the upper and lower side of described heat dissipation element is spirally connected with upper protective casing and measuring and protecting sleeve pipe respectively.
The utlity model has positive effect:
(1) in the utility model thermopair by between upper protective casing and measuring and protecting sleeve pipe, setting up heat dissipation element, in use, heat is delivered to the heat dissipation element place by the measuring and protecting sleeve pipe, and the heat that is delivered on the terminal box through upper protective casing again after the radiating treatment of heat dissipation element just can reach requirement; And need not be as traditional thermopair; the length of protective casing in the prolongation; effectively avoided because the problem that can't install that the installing space deficiency is brought, at heat dissipation element the installation that endoporus with the vestibule UNICOM of measuring and protecting sleeve pipe is thermopair thermo wires when being convenient to assemble has been set in addition.
(2) outer wall of the described measuring and protecting sleeve pipe in the utility model is provided with mounting flange or external thread, can make things convenient for the installation of thermopair by adopting this structure.
Description of drawings
Fig. 1 is a kind of structural representation of the thermopair of perfect heat-dissipating in the utility model;
Reference numeral shown in the figure is:
The 1-terminal box; The 11-lead terminal; The upper protective casing of 2-; 3-measuring and protecting sleeve pipe; The 4-temperature element; The 5-heat dissipation element; The 51-endoporus; The 6-mounting flange.
Embodiment
Below in conjunction with accompanying drawing a kind of embodiment of the present utility model is elaborated:
A kind of thermopair as shown in Figure 1, comprises from the cold junction to the hot junction successively: terminal box 1, upper protective casing 2 and measuring and protecting sleeve pipe 3 with lead terminal 11; Described terminal box 1 and described upper protective casing 2 welding; In the vestibule of described measuring and protecting sleeve pipe 3, be provided with temperature element 4; Be provided with heat dissipation element 5 between described upper protective casing 2 and the measuring and protecting sleeve pipe 3; Described heat dissipation element 5 centers are provided with the endoporus 51 with the vestibule UNICOM of measuring and protecting sleeve pipe 3, and the thermo wires upper end of thermopair is passed from this endoporus 51 with the junction block (not shown) of terminal box 1 inside and is connected; The upper and lower side of the described heat dissipation element 5 in the present embodiment is spirally connected with upper protective casing 2 and measuring and protecting sleeve pipe 3 respectively, also can adopt in practical operation in other connected modes that guarantee under the product quality prerequisite.
The thermopair of said structure is by setting up heat dissipation element 5 between upper protective casing 2 and measuring and protecting sleeve pipe 3; in use; heat is delivered to heat dissipation element 5 places by measuring and protecting sleeve pipe 3; and the heat that is delivered on the terminal box 1 through upper protective casing 2 again after heat dissipation element 5 radiating treatment just can reach requirement; need not as traditional thermopair, prolong the length of upper protective casing 2; effectively avoided because the problem that can't install that the installing space deficiency is brought, at heat dissipation element 5 installation that endoporus 51 with the vestibule UNICOM of measuring and protecting sleeve pipe 3 is thermopair thermo wires when being convenient to assemble has been set in addition.
In order to make things convenient for the installation of thermopair, the outer wall of the described measuring and protecting sleeve pipe 3 in the present embodiment is provided with mounting flange 6, specifically mounting flange is welded on the protective casing 3, when this thermopair is installed, fixes by this mounting flange 6 and the flange on the external unit; In practical operation, also can by threading on measuring and protecting sleeve pipe 3, be connected on the external unit in the mode that is spirally connected.
Obviously, above-described embodiment of the present utility model only is for the utility model example clearly is described, and is not to be restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And these belong to apparent variation or the change that connotation of the present utility model extends out and still belong to protection domain of the present utility model.
