Description
Technical field
The utility model relates to a kind of heating element heater, especially relates to a kind of half-packaging heat conduction aluminum heater.
Background technology
Beaker is a kind of container conventional in laboratory, common are test tube, horminess glass tube, evaporating dish etc., when test, often need to heat the liquid in beaker, can isolate heating by asbestos gauge.
Common heater is plate armature, as shown in Figure of description 2, heater is flat foundry goods 2a, when heating, the flat bottom of beaker is placed on foundry goods 2a and is heated, but this heater exists following problem: the contact area of beaker and heater is too small, and heat conduction efficiency is not high, and heat conduction directionality is bad.
Utility model content
The utility model is mainly existing for existing heater and problem that beaker contact area is too small, the efficiency of heating surface is low, and the half-packaging heat conduction aluminum heater that a kind of contact area is large, the efficiency of heating surface is high, conduction orientation is good is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of half-packaging heat conduction aluminum heater, comprise the foundry goods being connected with test beaker, described foundry goods is semicircle spherical structure, the intrados of foundry goods is suitable with the outer surface of test beaker, foundry goods is provided with cavity, the electrothermal tube that has integrally casting to form in cavity, the port of foundry goods is provided with circular support ear, support ear forms a circle along the port of foundry goods, several fixing holes on support ear, the bottom of foundry goods is connected with stem.This heater is by foundry goods and the moulding of electrothermal tube integrally casting, and after stem conduction, heating tube produces heat, passes to electrothermal tube, and electrothermal tube passes to the liquid in the test beaker in the cavity of inserting foundry goods again, heats.Because foundry goods is semicircle spherical structure, beaker is inserted after the cavity of foundry goods, and contact-making surface becomes sidewall contact from traditional bottom contact, and contact-making surface is larger, and heat conduction efficiency is higher, and has better centering and stability.The support ear supporting construction that is this electric heater, when heating, by the fixing hole on support ear, can be fixed on this electric heater on heating carrier, as sheet metal component etc.
As preferably, the radius of described foundry goods is not less than the cup radius of testing beaker.The radius of foundry goods is not less than the cup radius of testing beaker, and guarantee beaker can be put into the cavity of foundry goods easily.
As preferably, described stem has two, and two stems are symmetrically distributed in the bottom of foundry goods.After stem conduction, foundry goods produces heat.
As preferably, the bottom of described foundry goods is provided with aperture, and aperture is positioned in the middle of two stems.After beaker expanded by heating, volume can increase, and because the flat bottom of beaker and the bottom of foundry goods exist certain space, the volume of increase can be used for offsetting this space, and aperture is used for ensureing the inside and outside gas communication in space.
As preferably, described fixing hole has six, and six fixing holes are evenly distributed on support ear.When heating, by the fixing hole on support ear, this electric heater can be fixed on heating carrier, six fixing holes, stability is higher.
Therefore, the beneficial effects of the utility model are: foundry goods is semicircle spherical structure, and beaker is inserted after the cavity of foundry goods, and contact-making surface becomes sidewall contact from traditional bottom contact, and contact-making surface is larger, and heat conduction efficiency is higher, and has better centering and stability.
Brief description of the drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is a kind of structural representations of traditional beaker heater.
Shown in figure: 1-test beaker, 2-foundry goods, 3-electrothermal tube, 4-support ear, 5-fixing hole, 6-stem.
Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
As shown in Figure of description 1, a kind of half-packaging heat conduction aluminum heater, comprise the foundry goods 2 being connected with test beaker 12, foundry goods is formed by aluminium alloy casting, foundry goods is semicircle spherical structure, the intrados of foundry goods is suitable with the outer surface of test beaker, the radius of foundry goods is not less than the cup radius of testing beaker, foundry goods is provided with cavity, the electrothermal tube 3 that has integrally casting to form in cavity, the port of foundry goods is provided with circular support ear 4, support ear forms a circle along the port of foundry goods, on support ear, there are six fixing holes 5, six fixing holes are evenly distributed on support ear, the bottom of foundry goods is connected with stem 6, stem has two, two stems are symmetrically distributed in the bottom of foundry goods, the bottom of foundry goods is provided with aperture, aperture is positioned in the middle of two stems.
This heater is by foundry goods and the moulding of electrothermal tube integrally casting, and after stem conduction, heating tube produces heat, passes to electrothermal tube, and electrothermal tube passes to the liquid in the test beaker in the cavity of inserting foundry goods again, heats.Because foundry goods is semicircle spherical structure, beaker is inserted after the cavity of foundry goods, contact-making surface becomes sidewall contact from traditional bottom contact, contact-making surface is larger, heat conduction efficiency is higher, and having the beaker of better centering and stability same capability, the contact area of packaging type heat conduction aluminum heater will promote 80%, make heater have the higher thermal efficiency.The support ear supporting construction that is this electric heater, when heating, by the fixing hole on support ear, can be fixed on this electric heater on heating carrier, as sheet metal component etc.
Should be understood that this embodiment is only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
